1.1 TOUCHSCREEN DISPLAY OVERVIEW
The communicator has a 4.3-inch widescreen backlit TFT color touchscreen display with 480 x 272
WQVGA pixel resolution. The entire viewable area of the screen is an active touch surface. The touchscreen
responds to and is optimized for finger presses (even through gloves). NO stylus is necessary. Never touch
the screen with sharp objects – simply use your finger.
Display Layouts
There are two styles of displays presented on the communicator, system menu displays (Section 3.1) and
HART®
menu displays (Section 3.2).
The main system menu display is the initial menu at power turn on. It is also accessible from any HART®

2.0 GENERAL OPERATION
2.1 Power Button
The Power Button has two functions:
Power On – Whenever the communicator is in an “Off” state, pressing the power key turns the
communicator on. This is a complete system start. The communicator will execute a complete power op
sequence. Information regarding the time and date is briefly displayed to allow the user to verify the
communicator’s readiness
.
Standby Operation – When the communicator is fully on, and the power button is pressed briefly, the unit
enters the Standby state where allowed. In this state the display is off and most user input is ignored to
conserve battery power between uses. The on-board computer maintains the previous system state to
provided rapid recovery (Resume Operation).
Resume Operation - When the communicator is in Standby Operation, and the power button is pressed
briefly, the unit quickly resumes operation, returning to a fully “On” state of functionality at the same menu
level that was interrupted.
Power Off – When the communicator is fully on, and the power button is pressed for three seconds, the unit
will power down completely where allowed. This conserves the most battery power but requires a full
initialization when the unit is turned on again.
2.2 Backlight
The Backlight has 5 intensities from minimum to full Brightness. The user can select intensities by pressing
the Backlight Button. Backlight intensity affects battery life. A lower intensity level will increase operation
time.
2.3 Display Auto Dim Timer
Display Auto Dim is a configurable mode that allows the user to minimize the backlight when there is no
user or HART®
activity detected by the communicator for a user defined period of time. This period is
adjustable using the Display Auto Dim Timer. A shorter period will decrease battery consumption when the
communicator is not being used.
2.4 Auto Standby Timer
Auto Standby is a configurable mode that allows the user to automatically put the communicator into a
standby state when there is no user or HART®
activity detected by the communicator for a user defined
period of time. The inactivity period is adjustable using the Auto Standby timer. In combination with the
Display Auto Dim Timer, shorter period will decrease battery consumption. The standby timeout begins
when the Auto Dim Timer times out. If the Auto Dim Timer is set to “Never” the standby timeout will not
begin.
2.5 Portable Operation / Battery Life
The communicator is powered by a rechargeable li-ion battery pack for portable operation. A full charge
typically allows for 20 hours of typical operation. See section 2.7 for instruction on battery removal and
replacement. Replacement battery packs are available from Yokogawa (1W-9A820-1).

6
The battery pack contains an advanced battery fuel gauge that actively monitors the battery capacity and
therefore does not require any “battery training” throughout the life of the battery pack.
2.6 PC Communication / Recharging Cradle
The Recharging Cradle, included with each unit, automatically recharges the li-ion battery pack when the
communicator is properly inserted into the energized cradle. To fully charge a depleted battery pack takes
about four and one half hours.
The recharging cradle also connects the communicator with a PC for file updates to the communicator when
it is properly inserted in the cradle and a USB cable is attached from the cradle to a PC with the proper USB
drivers and Yokogawa update package. See section 5 for update instructions.
The Recharging Cradle is not intended to recharge a battery separately. To properly charge a battery
pack it is required to be inserted into a communicator prior to being placed on the charger.
Charging Indicator
There is a multicolor LED on the recharging cradle. This LED indicates the current charging mode.
Off – No battery pack inserted, or power disconnected.
Solid Green – Battery is charged.
Flashing Amber – Battery is charging.
Solid Amber – Battery temperature out of charging range (10°C-40°C), charge suspended.
Flashing Red – Battery fault.
Solid Red –Charger fault.

The Recharging Cradle is not rated for intrinsic safety and should only be used in a non-hazardous area.
See the “Hazardous Area Use” section of this manual and the Intrinsic Safety Control Drawing in the
Appendix of this manual for more information.
2.7 Battery Pack Installation & Removal
The battery pack is held into the communicator by two standard 6-32 screws with hexagonal sockets that
require a 7/64” hex key wrench.
To install the battery pack set the communicator enclosure with the display downward on a flat stable
surface. Rest the battery pack in the battery pack compartment of the enclosure leaving a ½” gap between
the battery pack and the connector on the communicator enclosure. Slide the battery pack upward along the
enclosure until the connectors mate completely and the screws are aligned with the threaded inserts on the
communicator body. Thread the screws into the insert to complete the installation.
For disassembly, reverse the order of the operations.
Over-tightening the battery case screws when assembling can cause damage to the communicator.
Maximum torque should not exceed seven in-lb.
Battery should be charged completely (10 hours) before using the communicator the first time. See Section
2.9 for detail on using the charging cradle.

2.7 Memory Card
The communicator is shipped standard with a µSD memory system card. The system card is used for storage
of required software, software updates, HART®
DD files and device configuration files. It is not intended for
use unrelated to the operation of the communicator. When the µSD memory system card is in the
YHC5150X, the user has no access to the card except with the Yokogawa provided PC software.
This card should only be replaced by Yokogawa part 1W-9P780, or its successor, and only under the
direction of Yokogawa personnel. Use of a non-system memory card will void safety certifications.
To access the memory card, follow the Battery Pack removal instructions.
To remove the memory card - Once the battery pack has been removed, press gently on the memory card to
unlock it from the card holder. Carefully remove the memory card from the enclosure ( Note: tweezers or
small needle-nose pliers can be helpful in removal and insertion).
To replace the memory card – Insert the memory card carefully into the card holder, contacts toward the back
of the communicator and card label towards the front (screen side) of the communicator. Be sure the
memory card is resting in the holder before releasing it. Gently press the card into the holder to lock it into
place. Replace the battery pack and secure it to the communicator enclosure.
2.8 Kick Stand
The communicator is equipped with a kick stand to provide a better viewing angle. The stand latches in the
down/open position. To return the kick stand to the up/closed position squeeze the base inwards from both
sides to unlatch it.

9
2.9 External Connections
Loop Communication Jacks / Lead Set – All models are equipped with a standard size banana jack on
0.75” center. The lead set supplied with the communicator has a standard banana plug on one end and mini-
grabbers on the other for convenient connections.
For Intrinsically Safe model YHC5150X, verify the instruments in the loop are installed in accordance
with intrinsically safe field wiring practices before making connection from the field device to the Unit’s
loop communication jack. See the Hazardous Area Use Section of this manual and the Intrinsic Safety
Control Drawing in the Appendix for more information.
Charging Cradle Connector
Each unit has an electrical connector located at the bottom of the handheld. The connector provides fast and
secure connection to the Communication / charging cradle supplied with each handheld. Seat the connector
end of the communicator into the charging cradle with the front of the communicator facing the front of the
charging cradle. Inserting the communicator into an energized cradle begins the charge cycle and allows
communication with a PC. See section 5 for update instructions.
The Recharging Cradle is not rated for intrinsic safety and should only be used in a non-hazardous area.
See the “Hazardous Area Use” section of this manual and the Intrinsic Safety Control Drawing in the
Appendix of this manual for more information.

2.10 Keyboard Functionality
The keyboard is logically arranged into four areas based on the frequency of use. The alpha and fixed
function keys will be used less frequently than the navigation and numeric keys.
The alpha keys contain all 26 characters of the ISO basic Latin alphabet. They are arranged in the same
order as a standard QWERTY keyboard. The alpha keys are used for text data entries as well as hexadecimal
(A to F) numeric data entries. When not entering data these keys are ignored.

Decision keys (hard key) are active when decision buttons appear on the screen. Their function is duplicated
by the decision buttons (touch screen button). Decision keys are also used for some auxiliary functions. See
sections 3.2 (Create shortcuts) for detail.
Navigation keys are used to move focus around the display and to select the item that is in-focus.
Information key provides on-screen help when available.
Numeric keys are used for text or numeric data entries.
Numeric keys are also used as accelerators to advance menus and initiate actions when indicated by the on-
screen icons.

2.11 Touch Keyboard Functionality
The YHC5150X Series and HART®
communication support the ISO Latin-1 (ISO 8859-1) character set for
most text data entry. This character set contains 191 characters. Of these characters 65 are available on the
communicator main keyboard. The remaining characters, and duplication of the ISO basic Latin alphabet
(lower + upper case) are available from the touch screen. Whenever a text edit window appears the touch
keyboard is visible too. There are multiple keysets to allow larger keys, improving usability. Since the ISO
basic Latin alphabet characters are available from the dedicated keyboard, they are the last touch keyset. The
touch keys are grouped by language usage wherever practical, and keysets are ordered based on estimated
usage. The first touch keys that are visible are commonly used symbols. To move to other keysets use the
“<<<” and “>>>” touch keys. Upper/Lower case selection (Cap Lock) does not affect keyset #1 or keyset
#2 (symbols). Navigation of the keys on the text edit display is by touch screen or the Navigation Key set.
A red box surrounding the key signifies that the key has focus. Some text data parameters (“tag” for
example) do not support the full ISO Latin-1 (ISO 8859-1) character set. When this is the case, the non-
functional touch screen characters will be gray. Since these data types do not support lower case alpha
characters, be sure the “Key Caps Locked” symbol is present, or the alpha hard keys will appear not to
function. When the characters entered in the edit box reach the string size limit for a specific parameter, , the
cursor disappears, a yellow block appears after the last character and additional character entry is ignored.
For example, “tag” is limited to eight characters. If the length of the data entry exceeds the field size on the
screen the characters can be shifted left or right by sliding your finger in the data field. Data entry always
shifts the characters full left so the end of the entry is visible.

The communicator provides device specific HART®
communication functions that allow the user to poll,
configure and maintain supported HART®
field devices. The communicator uses Universal, Common
Practice and Device Specific commands to facilitate communication with a HART®
field device. The
communicator can be used to commission devices, reconfigure devices, or maintain devices through
analog and sensor trim adjustments. Many other features defined by the device manufacturer are also
supported.
The communicator will communicate with any HART device through Universal and Common Practice
Commands using the standard Generic DD but must have the DD for a specific HART®
device installed
before it can execute Device Specific Commands. When HART®
device support for new devices becomes
available, the communicator software can be easily updated using a PC with an internet connection and
software provided.

4.2 HART®
Connections
HART®
connections are made using two standard banana jacks (3/4” center) located at the top end of the
communicator. Refer to the following diagram. Polarity is not a concern for HART®
connections so both
jack collars are black. Yokogawa supplies a HART®
lead kit (1W-A900529-00014) complete with mini-
grabber connections and a 250 Ω load resistor with each unit.
Consult the transmitter manual for proper connection in hazardous locations
For low load loops (less than 250 Ω), a 250 Ω resistor may be needed in the loop to insure reliable HART®
communication. Yokogawa supplies a 250 Ω load resistor in the form of a standard adaptor (1W-A36821).
Refer to the following diagram for connection details.
HART®
connections are standard banana jacks
(3/4” center)

30
When connecting the communicator to a loop with a resistive load greater than 250 Ωs, the HART®
jacks
may be connected across the load, the loop + and -, or to the HART®
device communication terminals. Refer
to the following diagram for connecting across the loop + and -.
.
Do not connect the communicator across the loop supply. This does not provide the
proper resistance and no HART®
communication will be possible.
4.3 HART®
Communication
Upon power up the communicator automatically polls for HART®
devices in the range specified on the
HART®
Setup System menu (default range is zero).
The HART®
Connection status bar on the system screens indicates the current state of the HART®
connection.
If you select the gray bar, no action will occur. The communicator will continue to send poll address
messages within the configured range as long as a device has not been selected for connection. If new
devices are added to the loop, within the configured range, they will be detected automatically.
Or the currently selected device is in the process of connecting.
When the bar is gray: there is no device connected;

31
If the bar indicates devices have been found you can select which device to connect by selecting the bar.
This brings up a list box from which to pick your device.
Once you choose a device and press Accept, the box will collapse and the communicator will initiate
connection. Once the device is connected the bar will turn green.
If the poll address range is a single address, and a device is found at that address, the communicator will
immediately initiate connection, and additional polling is terminated. The bar will turn green when the
initialization is complete.
Whenever the bar is green:
It indicates that a device is actively connected to the HART®
network. The communicator does not
continue to poll for other devices. If the green bar is selected the communicator will initiate the online
HART®
menus. If a different device is desired selecting the Restart Poll icon will begin a new search for
devices and the established HART®
connection will be lost.
4.4 Device Specific & Generic HART®
Communication
The communicator supports a large and growing number of Device Specific DDs (Device Object Files). To
facilitate communication with HART®
devices that are not yet supported with Device Specific DD files or that
do not require DD files, the communicator includes Generic HART Communication capability. This allows
the user to communicate with any HART®
device using Universal and Common Practice commands to poll,
configure, and maintain HART®
devices. Specific functions supported include most polling, tagging, device
configuration and trim operations for analog outputs. Generic communications do not support Device Specific
commands for higher order HART®
functions. Review the User’s Manual for the HART®
device of interest
for more information on device specific command support.

32
4.5 Using Generic HART®
Communication
The Generic HART®
Communication mode starts automatically when HART®
communication is initiated
with a device for which no Device Specific DD (device object file) is stored in the handhelds flash memory.
When this occurs, line two of the display will indicate “Generic” and the device tag number.
In general, the Generic HART®
mode operates similarly to its device specific DD counterpart (see HART®
Communication section of this manual for more details). However, the communicator does not display Device
Specific related communication menus or options when in the Generic communication mode. For example, the
Zero and Sensor trim menu options (normally executed by Device Specific commands) are not displayed for
pressure transmitters without DD support.
4.6 Managing Device Configuration Files
The current parameter settings for a connected HART®
device can be stored into a file on the uSD system
card for later use. This file can then be used in duplicating settings to a new device of the same model,
restoring settings to a repaired device, and for documentation purposes. What parameters are stored is
defined by the manufacturer of the HART®
device.
If the Commit Changes button is illuminated, the communicator parameters should be committed
to the device before storing or retrieving a configuration. If the parameters are not committed and the
user chooses to store the parameters, the user is warned that the parameters do not match the device. If
the user decides to continue with the store the file is marked as “As Modified”. Any online modifications
to parameters done prior to restoring a configuration that were not committed to the device are lost, if
those parameters are in the stored configuration.
Selecting the Configuration Options button will bring up a list of configuration actions.
To store a device configuration, the user selects Configuration Store.
Dialog boxes direct the user to appropriate actions:
1. The user is prompted for a file name. The default file name is the tag parameter defined in the device. The
user may change this to any file name not currently in use for this device model. Unsupported characters are
grayed-out and ignored. If the user picks a name already in use, the communicator gives them an option of
cancelling or overwriting the current file.
2. If the configuration has not already been marked as “As Modified”, the user has to choose a configuration
type. The choices are “As Found” (device settings before modification) or an “As Left” (device settings after
modification).
The configuration file is saved in the communicator uSD card memory and can be restored to update any
transmitter of the same model and revision.
To restore a device configuration, the user selects Configuration Restore. The configuration files are
segregated by device model and revision. When a restore is requested, only the configurations that
pertain to the model of the connected device are presented. The user chooses a file and selects Accept
(). This will restore the stored parameters to the communicator’s parameter cache. The parameter
changed indicator beside affected parameters will appear, and the Commit Changes button is illuminated.

33
The user now has the option of making further modifications to the parameters on the HART®
menu, or
committing them to the device.
4.7 Communication Troubleshooting
If a HART®
device is connected to the unit but “No Devices Found” notification is received, or the device is
not in the table of found devices:
1) Make sure all connections are correct and secure. Check for shorts, open circuits and multiple
grounds.
2) Determine if the loop resistance is greater than 250Ω and less than 1100Ωs. If less than 250 Ω
then use the supplied 250 Ω load resistor in series with the loop (see diagram HART®
Connections
section).
3) Determine if any device is in burst mode. Disable burst mode if possible during troubleshooting.
4) Check the polling address type and range selected from the system menus. If the polling address
set on the transmitter is outside of the range selected for the communicator, the device will not be
discovered. Set the poll type to “by address” and set the polling address range to the maximum (0-
15 for HART®
Universal Revision 5 devices, 0-63 for newer HART®
devices). Start a new poll
and determine if the device is found.
5) If multiple HART®
devices are in the loop, there could be an address conflict (two devices at
same address). Testing the devices individually is the best path.
6) Determine if there are multiple master devices on the loop. HART®
communication only permits
one primary and one secondary master. Remove all other master devices from the loop for
troubleshooting.
When the message “Generic” is displayed after connecting to a HART®
device there are two possible causes:
1) No device specific DD for that device is currently installed in communicator memory. This
could occur if the device DD has not been released by the HART Communication Foundation
(visit their website for full list), or if the DD database on your PC requires updates. See section
5 for update instructions. The connected HART®
device supports only HART®
Universal and
Common Practice commands (i.e. generic commands). There are several such devices on the
market, particularly level type devices.
If multiple devices of the same name appear at different addresses, the cause is normally a HART®
Universal Revision 5 device in the loop and the polling range selected on the communicator extending
beyond HART®
polling address 15. Addresses beyond 15 were undefined until HART®
Universal
Revision 6.
