Max Working Pressure: The maximum that can be applied to both process ports simultaneously without affecting sensor performance.
The One Series transmitter-switch product line is based on an all-solid-state electronic module that incorporates a microprocessor.
The One Series Field Safety System™ is a loop-powered, all-in-one device connected directly to the final element and replacing a
transmitter, safety relay, trip amplifier, and logic solver. It has an embedded high capacity, programmable safety relay that provides
extremely fast response time in the event an emergency shutdown of a final control element is triggered. The One Series Field
Safety System™ incorporates UE’s patented IAW™ self-diagnostics, redundant and diverse signal processing, and software algo-
rithms to detect abnormalities in the process, and internal faults within. The device meets the latest IEC 61508 standard for SIL 2
SIS and the requirements of SIL 2 for random integrity at HFT = 0, SIL 3 for random integrity at HFT = 1, and SIL 3 for systematic
capability.
Not all abnormal conditions require emergency shutdown, so the One Series Field Safety System™ provides additional logic
outputs for use in voting logic schemes that could report warnings prior to a shutdown. This feature provides the ability to balance
safe working environments with process throughput when conditions permit it.
The One Series Field Safety System™ provides an explosion-proof type 4X/IP66, weather-tight enclosure suitable for harsh envi-
ronments and hazardous (Class I, Division 1, Zone 1) locations. Repeatability rivals that of a process transmitter, with a 0.1% of
full range while the switch set point and deadband (hysteresis) of the Safety Relay Output are fully programmable over the entire
range of the sensor. Reaction time for the One Series Field Safety System™ to a process change is less than 100 milliseconds.
When filter settings are set to “OFF,” switch status and Safety Relay Output are moved to the safe state (open position) in less than
100 milliseconds, and the 4-20 mA output stabilizes to 90% of a step response within 250 milliseconds.

I Am Working (IAW™)
The One Series Field Safety System™ also contains UE’s patented IAW™ self-diagnostic software. On a continuous basis, the IAW™ algorithm
checks for proper operation, and locally reports the status using messages or revolving arrows on the display. For remote reporting, a discrete
IAW™ output signal can be monitored by logic solver and used to detect normal, tripped, and fault conditions. A discrete outputs truth table is
provided on page 18. IAW™ self-monitors, searching for possible faults, both within the instrument and in the overall system (a list of the various
fault codes is outlined in table 5, page 17). In the event of a fault condition, the One Series Field Safety System™ will attempt to display the problem and
provide remote indication signals using the IAW Status and NAMUR NE43 standard 4-20 mA outputs. In the case of certain micro-controller faults, the revolving
arrows may freeze or go out, indicating that a failure exists. If loop power is interrupted to the One Series Field Safety System™, the display will go blank
and all discrete outputs will open.
DISPLAY FEATURES AND DIAGNOSTICS
The One Series Field Safety System™ features a large, easy to read LCD display (See Figure 1). It is used for three main purposes: process
indication, programming and switch status/troubleshooting.
In the Process Display mode, the display may be indicating the following:
• Current process value and units of measure: A value will be displayed as long as the reading is within 103% of the full
scale range noted on the nameplate. For valves beyond 103% of range, the PV is replaced with a scrolling message OVER RANGE.
• I Am Working (IAW™) status: When the unit is working properly, a circular 4-segment arrow will be revolving around the letters “IAW™” in
the top center of the display.
• Offset/Span Adjustment: The word “offset” will appear above the process value, indicating that the factory offset and/or span
calibration has been modified by the user.
In addition, the user can easily access information such as the set point, deadband and minimum/maximum process readings:
By pushing the right gbutton once, the display will scroll as follows:
SP1 XX.XX DB1 XX.XX SP2 XX.XX DB2 XX.XX
By pushing the left 2button once, the display will scroll the min/max process values recorded in memory:
MAX XX.XX MIN XX.XX
The display will automatically revert back to the Process Display mode after scrolling.
ALARM CONDITION
When the process goes beyond the set point, the display will begin to flash, alternating between the process value and “SW1”. This indicates that
set point has been reached, causing the Safety Relay Output (SRO) and Status Switches to open. The display will continue to flash until the process
has returned to a value beyond the deadband, at which point the display will revert to normal operation and process value display. If the unit was
programmed to have a latching output, a small “Latch” icon will light in the display when the set point is reached, indicating that the output is
latched and needs to be manually reset.
FAULT CONDITIONS
In the case of a fault condition, the display may indicate the following:
• If the IAW software detects a fault it will display an error code and force the SRO, SRO Status and IAW Outputs to open state and the 4-20 mA output to the
fault current.
• If the power supply or the wiring fails, the display will go blank. All switch outputs will open (fail safe open) and the 4-20 mA signal will go to zero.
(See the Fault Codes and the Discrete Output Truth Table on pages 17 and 18 for a complete description of fault diagnostics and the response by the One Series
Safety Transmitter.)

PART I - MOUNTING
Tools Required: Screwdriver for mounting bolts; 4 mounting bolts (1/4”Max.)
NOTE: For optional surface and pipe mounting kit, order part no. 6361-704. See page 20.
BEFORE INSTALLING, CHECK THE SENSOR MODEL SELECTED FOR COMPATIBILITY TO THE PROCESS MEDIA IN CONTACT WITH THE SENSOR
AND WETTED PARTS.
IN ALL APPLICATIONS, SECURE THE ENCLOSURE AS DETAILED BELOW. DO NOT MOUNT VIA THE PROCESS CONNECTION ONLY.
Figure 1

IM_ONE_Safety-07

Mount the device using the four (4) 1/4” clearance holes in the enclosure base. Plumb sensor to the process port. See page 20-21 for dimensions.
The device may be mounted in any position except with the sensor connection facing up. Ensure the process connection is sealed to the process
port to prevent leakage. Care should be taken to minimize effects of shock and vibration. The One Series should be protected from direct sunlight
and rain in outdoor installations using a shroud (user supplied). NOTE: the optimal display viewing position is 6:00.
FOR PRESSURE AND LOCAL TEMPERATURE MODELS ALWAYS HOLD A WRENCH ON THE SENSOR HOUSING HEX WHEN MOUNTING DEVICE. DO
NOT TIGHTEN BY TURNING ENCLOSURE, THIS WILL DAMAGE THE CONNECTION BETWEEN THE SENSOR AND HOUSING.
FOR DIFFERENTIAL PRESSURE MODELS (ESPECIALLY LOW RANGE MODELS), MOUNT THE SENSOR LEVEL TO MINIMIZE ANY PRESSURE
READING OFFSETS. THE OFFSET COMMAND MAY BE USED TO ZERO THE DISPLAY, (SEE PAGE 13 FOR ADDITIONAL INFORMATION).
PROCESS CONNECTIONS AND SENSOR INSTALLATION
NEVER INSERT ANY OBJECT INTO THE PRESSURE SENSOR OPENING. DAMAGE TO THE SENSOR WILL RESULT, AFFECTING ACCURACY.
Pressure and Differential Pressure Models
To pipe mount: Thread the pressure connection onto the pressure port, with thread sealant, making sure that the mating threads are clean and
free of debris. Use a wrench on the pressure connection hex to tighten. Test for leaks. On Differential Pressure models, the Low (L) side pressure
must NOT exceed the high (H) side pressure. Damage to the sensor may result.
Local and Remote Temperature Models
For Local Ambient Sensing (model L): Mount using the mounting holes on the electronics housing. Mount the device to ensure that the sensor
housing will not be damaged and where the measured temperature is representative of the surrounding environment.
For Local Spring-Loaded (model T): A suitable thermowell, made from corrosion-resistant material, 5 threads engaged minimum, with thread
sealant, is required to maintain enclosure type 4X/IP66.
For Remote Sensing: Route the extension wire to avoid contact with live components or close proximity to electrical noise sources. Avoid kinks, or
excessive flexing. Tighten the ferrule fitting, if applicable.
For Surface Sensing: Secure the sensor housing to the pipe or vessel using an adhesive or strapping method suitable for the application.
For Immersion Sensing (models C, H, R & L): Use of a thermowell is highly recommended to aid in maintenance, testing and preservation of the
system integrity. For existing thermowells with 0.375” bore, an insert is available from UE as part number 62169-44 (see Figure 2). The adapter provides a
faster heat transfer by adapting the 0.250” diameter temperature sensor housing to a larger bore 0.375” thermowell. Heat transfer compound is recommended
in the bottom of the well and inside the adapter opening.
Insert the sensor housing (0.25”diameter) into the well ensuring that the sensor’s sheath bottoms out and the well is completely immersed in
the media (2.5”min.) Screw the sensor’s nipple into the thermowell, with thread sealant, by placing a wrench on the union nut. Tighten the union
connector.
For best temperature measurements, the sensor housing must be in full contact with the surface or media being measured. Heat transfer compound
may be used to aid in fully transferring the media temperature to the sensor housing. Locate where the temperature is most representative of the
system. Minimum insertion depth is 2-1/2”. Sensor dimensional drawings are shown on page 21.

The One Series Field Safety System™ enclosure includes two conduit openings,
one intended for the high-power SAFETY RELAY OUTPUT (SRO) wiring and the
other intended for low-level signal and analog 4-20 mA wiring. 4-20 mA signals
shall be wired using a shielded/twisted pair to minimize the effects of electrical
interference. Please follow local electrical code requirements for explosion/flame
proof instrumentation.
The diagrams in Figures 5 and 6 provide a rear view of the display module after
it has been removed from the base enclosure and an inside view of the base
enclosure circuit boards. Terminal Block 1 (TB1) is located on the display module.
All other terminal blocks (TB2 - TB4) are located inside the base enclosure.
Model 2SLP is loop-powered and is connected directly to an analog input of a PLC
or DCS via TB1 providing a 4-20 mA analog signal (see Table 3). (Polarity must
be observed). The loop connection powers the entire One Series Field Safety
System™, including the Safety Relay Output switch actuation. The auxiliary SAFETY
RELAY OUTPUT is connected via TB2 and is intended to switch an external load.
Refer to Table 3 for the SAFETY RELAY OUTPUT switch ratings.
Figure 6 shows the switch wiring connections located at TB2, TB3 and TB4 inside
the base enclosure. TB2 A and B terminals are provided for the external power
supply inputs to be switched by the Safety Relay Output. The SRO at TB2 C and D
terminals provide connections to the Safety Relay Output switch. Polarity must be
observed on all VDC switches. Please refer to the wiring diagrams shown on page
7.
The SRO Monitor function, if used, requires a connection to VDC (+) or VDC (-)
depending on whether the SRO circuit arrangement is sinking or sourcing (either
Neutral1 or Neutral2 for model 2SLP47). This connection allows the SRO current
to be measured that is sent out to an external load (final element), allowing the
IAWTM diagnostics to determine the integrity of the SRO wiring and if the SRO is
functioning properly.
NOTE: As an alternative to loop power, model 2SLP may be wired directly to a
24 VDC power supply (+) and minus (-) terminals. In this wiring configuration,
power is provided for all switching and diagnostic functions but a 4-20 mA output
is not possible. This alternative method of powering the One Series Field Safety
System™ may be used when loop power is not available and a 4-20 mA output is
not desired.
Two additional discrete outputs are available at TB3 and TB4 - SRO STATUS and
IAW OUTPUT. These are intended for use in Safety Instrumented Systems (SIS)
applications and for monitoring certain One Series Safety Transmitter functions.
These discrete signals are useful for voting logic schemes where the safety PLC can
decide to initiate an emergency shutdown (ESD) or an alarm depending on their
state. These outputs may also be used to distinguish between a process upset
(set point reached) or the IAW™ self-diagnostics detecting a fault with the One
Series Field Safety System™. Please refer to table 4 on page 15 for additional
information.
NOTE: Do not exceed the maximum switch ratings of the SAFETY RELAY OUTPUT,
IAW™ OUTPUT and SRO STATUS signals or permanent damage to the One Series
Field Safety System™ may result. Please refer to Table 3.

The following wiring diagrams show the One Series Field Safety System™ fully configured where the health status (IAW) and SRO switch status signals are
being monitored by a logic solver (PLC or DCS). These connections are not required; however, UE recommends monitoring the IAW signal to maximize the safe
failure fraction in an SIS application. Additionally, wiring the SRO to an external load (final element) is not required.
For direct control of a final element from the One Series Field Safety System™, Figures 11-13 show the recommended SRO wiring methods. The wiring con-
nection shown at TB2 – A+B is required for proper operation of the SRO Monitor diagnostics only if this feature is turned ON in the menu. The default factory
setting for SRO Monitor is OFF.

PART III - PROGRAMMING
Basic Programming
Tools Required: Programming Flowchart (see Flowchart 1, page 19)
Programming of the One Series Field Safety System™ is accomplished using the two buttons on the faceplate (labeled 2and g
see Figure 15). Stepping down through the main menu using the left 2button, you can access the various commands of the software
menu. The right button is then used to move into the command submenu for setting up or modifying the parameters.
NOTE: The flowchart on page 19 shows the enitre programming commands menu structure. Before removing the enclosure cover,
please read the instructions on page 5. The programming menu is a single direction lop, with submenus embedded within, so there is
no way to back up in the program. If you need to make a correction to a prior Main Menu step, you will need to continue forward, exit,
then re-enter the program to step through to the appropriate feature. If you are in a Submenu, you will need to continue to the begin-
ning of the menu item and re-enter the Submenu to make the correction.
Entering the Programming Mode
NOTE: While in the Programming Mode, the One Series Field Safety System™ will remove itself from service (go offline). All out-
puts are set to the fail safe state and the Field Safety System™ ignores process variable input from the process sensor. The Safety
Relay Output and Status, and the IAW™ Output signal will open. The control system will interpret these signals as a detected fault and
a process upset (set point reached) simultaneously. It is essential to alert the control system operators before entering the
Programming Mode.
Use the Flowchart on page 19 as a guide through the various commands in the Programming Mode.
• Press and release both buttons 2g simultaneously and then press the right button gto enter the password.
• Enter the 4-digit password. The factory defualt password is “0000”.
• The left 2button increments the blinking digit.
• The right gbutton sets the digit and moves to the next.
• Once a valid password is entered, “OK” will appear on the display.
• Press and release the right gbutton.
• CLR MAX/MIN (or MAN RSET if Latch is set) will appear on the display.
This is the first command prompt in the Programming Mode.
NOTE: The Field Safety System™ will automatically exit the Programming Mode and resume monitoring the process (go back online)
if two minutes elapse without a button being pressed. The One Series recalls all previously saved parameters from memory and any
program changes that were made will be discarded. This two-minute timeout feature prevents the One Series from being left offline
accidentally.
Exiting the Programming Mode
When any of the programming commands are displayed, it is possible to escape and exit the Programming Mode by pressing the left
2and right gbutton simultaneously. Doing this redirects the program to the Save Changes menu location, which is only possible at
menu actions indicated by an asterisk (*) on the Programming Flowchart, found on page 19.
NOTE: It is also possible to exit the Programming Mode by repeatedly pressing the left 2button from any programming command until
the Save Changes menu location is reached.
Saving Programming Changes
When changes have been made to the programming settings, a choice is provided to Save or Discard the changes. At any prompt:
• Press both left 2and right gbuttons to display SAVE CHNG menu.
To Save changes, press the right gbutton. NO (the default) will be displayed.
• Press the left 2button to toggle and display YES.
• Then press both left 2and right gbuttons to confirm, save the changes and return to the Process Display mode.
The One Series will resume process monitoring (go back online) using the new programming parameters.
To Discard changes, press the right gbutton. NO will be displayed.
• Press both left 2and right gbuttons to confirm, discard changes and return to the Process Display mode.
The One Series will resume monitoring the process (go back online) recalling all previously saved parameters from memory.

BASIC FEATURES
Setting the Units of Measure
The One Series Field Safety System™ allows the units of measure to be set in the field. The default units are pounds per square inch
(PSI) for pressure models and degrees Fahrenheit (˚F) for temperature models.
• To change the units of measure, enter the programming mode. Press the left 2button. The display will scroll SET UNITS.
• Press the right gbutton and the display will read the default units psi or˚F.
• Repeatedly press and release the left 2button to select from the available choices. Stop at the desired choice.
• Press the right gbutton to make the selection. The display will return to “Set Units.”
• Press the left 2button to continue on in the menu or press both left 2and right gbuttons to exit the Programming Mode and
save changes.
NOTE: MAX/MIN memory is reset (changed to zero) whenever the units of measure have been changed. Set Point, Deadband, Offset,
Span, Plug Port, and 4 mA and 20 mA values are recalculated for the newly selected units of measure.
Setting the Safety Relay Output Mode, Set Point and Deadband
Please refer to the Programming Flowchart, page 19.
NOTE: The One Series Field Safety System™ is intended for use in functional safety applications. As a result, the Safety Relay Output
(SRO) was designed to fail safe (open) if power is lost to the One Series Field Safety System™ or if a fault is detected by the IAW
self-diagnostics.
• Enter the programming mode (see page 10).
• Press and release the left 2 button until SW1 appears on the display.
• Press the right g button. The previously selected mode will appear. OPEN RISE is the factory default.
NOTE: The One Series Field Safety System™ has three operating modes:
OPEN RISE - The Safety Relay Output opens on rising process values that reach the set point.
OPEN FALL - The Safety Relay Output opens on falling process values that reach the set point
OPEN WINDOW - The Safety Relay Output opens when process values are within a specified range set by two points, set point high and
set point low.
Please use the Safety Relay Output Decision Logic (Figure 13, page 12) for help with setting the appropriate Safety Relay Output mode.
• Press and release the left 2button until the desired mode appears.
• Press the right gbutton to select the mode and move on to the set point. SP will appear.
NOTE: The set point is the process value at which the One Series Field Safety System™ opens the Safety Relay Output. The Set Point
is fully programmable throughout the operating range of the sensor as noted on the device nameplate.
• Press the right gbutton to select a positive or negative set point. POS is the default. Use the left 2button to change to NEG.
• Press the right gbutton to view and change the set point. Press the left 2button to increment the blinking digit. Press the right
gbutton to enter and move to the next digit.
• Press the right gbutton to enter a new Deadband. DB will show on the display.
NOTE: The Deadband is the amount above or below the set point at which the One Series Field Safety System™ resets the Safety
Relay Output, returning it to the normally closed state. Deadband is represented as a value which is added or subtracted from set point,
depending on the control mode.
• Example 1: If the Control Mode is OPEN RISE and the set point is 100 and the deadband is 10, the Safety Relay Output will open as
pressure rises to 100 and close (reset) as the pressure falls to 90.
• Example 2: If the Control Mode is OPEN FALL and the set point is 100 psi and the deadband is 10, the Safety Relay Output will open
as pressure falls to 100 psi and close (reset) as pressure rises to 110 psi.
NOTE: Deadband should be set wide enough so that frequent or rapid Safety Relay Output cycling (chatter) does not occur but narrow
enough to satisfy the process conditions. A Deadband value of zero is undefined and, therefore, not permitted.

• Press the right gbutton to view and change deadband. Press the left 2button to increment the blinking digit. Press the right g
button to enter and move to the next digit.
• Press the right gbutton to enter a new Deadband. SW1 will show on the display.
NOTE: The Set Point and Deadband settings are subject to the accuracy of the instrument. Actual switch points may vary up to +0.5%
of the sensor’s maximum range at room temperature. Example: The P15 sensor has a range of 0 to 300 psi. When setting a Set Point
of 150, the actual switch point may occur between 148.5 and 151.5 due to the accuracy error of +1.5 (300 x 0.5%).
Figure 16
Resetting the Maximum & Minimum Values
The One Series Field Safety System™ continuously records the readings from the sensor and stores the minimum and maximum (MAX/MIN,
peak hold) values in non-volatile memory. The max/min values may be viewed at any time by removing the enclosure cover (page 5) and pushing
the left 2button. The display will scroll the MAX/MIN values and then return to the Process Display mode.
To reset the values, enter the Programming Mode (see page 10). Repeatedly press the left 2button to get to the CLR MAX/MIN command and then
press the right gbutton two times. After exiting the Programming Mode and saving the changes (see page 10), the values will be reset to the
current reading and begin recording again.

ADVANCED FEATURES
NOTE: No initial configuration of these features is required. The default for these advanced commands is zero or off.
Adjusting Display Offset
The One Series Field Safety System™ is factory calibrated to 0.25% of the sensor’s maximum range at room temperature. In some
installations, it may be necessary to adjust the display’s offset due to the range and position of the sensor. Chemical seals with long
capillaries combined with low maximum range sensors are a common cause of offset error. The OFFSET command allows the user
to enter a positive (“POS”) or negative (“NEG”) offset to the display readings. An offset adjustment of up to +10% of the sensor’s
maximum range is allowed. If adjusting OFFSET, it may be necessary to adjust SPAN (see below).
Example: When the sensor has a zero pressure applied, but the display reads a value other than zero, entering the additive inverse
(reversing the sign) of the displayed value for OFFSET will force the display to read zero.
NOTE: Any numerical value entered other than 0.00 will cause the display to indicate “Offset” just above the process reading in the
process display.
USE OF THIS OPTION MAY CREATE A CONDITION WHERE THE DISPLAY MAY INDICATE “0.00” WHEN SIGNIFICANT PRESSURE OR
TEMPERATURE (UP TO 10% OF MAXIMUM RANGE) EXISTS IN THE SYSTEM. INDEPENDENT VERIFICATION OF THE PROCESS VARI-
ABLE SHOULD BE DONE PRIOR TO MAINTENANCE ON THE SYSTEM WHEN “OFFSET” APPEARS ON THE DISPLAY.
Refer to the Programming Flowchart on page 19.
• Enter the Programming Mode and use the left 2button to move to the OFST command.
• Press the right gbutton to select a positive or negative offset. POS is default. Use the left 2button to change to NEG.
• Press the right gbutton to view and change the offset. Zero is the factory setting. Press the left 2button to increment the blink-
ing digit. Press the right gbutton to enter and move to the next digit.
• Press the right gbutton to enter the new offset and return to the main menu.
Adjusting Span
SPAN provides an adjustment to shift the slope of the sensor’s response curve to accommodate an offset value other than zero. To
adjust SPAN, calculate and enter a new SPAN value.
To calculate the SPAN value, apply a reference source below maximum scale to the sensor. Record the value that shows on the One
Series Field Safety System™ display and the reference source value. Divide the reference source value by the display value and then
multiply the result by the sensor’s upper range.
FORMULA: SPAN = reference source / display value x upper range value
• Pressure example: For a sensor range of 0 - 100 psi, choose a reference source (90) below the upper range limit (100) to
prevent an over range condition. Divide the reference source value from the resulting display value (88). Multiply the result by the
upper range limit. Span = 90 / 88 x 100 = 102 (rounded)
• Temperature example: For a sensor range of -40 to 450ºF, choose a reference source (400) below the upper range limit (450) to
prevent an over range condition. Divide the reference source value from the resulting display value (404). Multiply the result by
the upper range limit. Span = 400 / 404 x 450 = 446 (rounded)
Refer to the Programming Flowchart on page 19.
• Enter the Programming Mode (see page 10) and use the left 2button to move to the SPAN command.
• Press the right gbutton to select a positive or negative span. POS is the default. Use the left 2button to change to NEG.
• Press the right gbutton to view and change the span. Zero is the factory setting. Press the left 2button to increment the blink-
ing digit. Press the right gbutton to enter and move to the next digit.
• Press the right gbutton to enter the new span and return to the main menu.

IM_ONE_Safety-07

NOTE: To return to factory calibration settings, enter all zeros for both SPAN and OFST.
Setting the Latch Mode (Manual Reset)
The Safety Relay Output can be configured to latch open when the set point is reached. Refer to the Programming Flowchart on page
19.
• LCH1: In the Programming Mode, press the right gbutton.
• If OFF is displayed, press the left 2button to set LCH1 to ON.
• Press the right gbutton to set the latch. When latch mode is on (set), the Safety Relay Output changes state from closed to open
when the set point is crossed and remains latched until the Safety Relay Output is manually reset by the user or the One Series
Field Safety System™ is power cycled.
When latched, the display will read MAN RSET.
To Reset the Latch
• Enter the Programming Mode (see page 10). If the Latch is set, the display will read MAN RSET. To return to the Process Display
without resetting the latch, press the right gbutton.
• To continue programming without resetting the latch, press the left 2button.
• Press both 2g buttons to reset the latch. The display now reads RSET DONE.
• Press the right gbutton to return to the Process Display.
• Press the left 2button to continue Programming.
Setting the Plugged Port Feature
The One Series Field Safety System™ IAW™self-diagnostics have the ability to detect that the process port may be plugged. It does
this by monitoring the sensor for changes over time. The amount of change and the time period are programmable. If the process
variable does not change by the amount and selected time period, the display will indicate PLUG and the IAW™Output will open, indicat-
ing a fault. Refer to the Programming Flowchart on page 19.
• Enter the Programming Mode and press the left 2button until PLUG PORT is scrolling on display. Press the right gbutton.
• There are four possible selections -
• OFF - This disables the plugged port function and is the default setting. This should be done where sensor plugging is
not a concern or where the system pressures may not change over time (example: a storage tank).
• 1 minute
• 1 Hour Maximum time with no process variation before fault indication
• 24 Hours
• Using the left 2button, select a time.
• If OFF is selected, press the right gbutton to return to the PLUG PORT command and leave Plug Port deactivated.
• Press the right gbutton to enter a process value < 10% of the sensor’s maximum range. This number represents the minimum
variation expected in the process value over the time period entered above under normal operating conditions. Each time the
process value reaches this value, the Plug Port timer is reset.
NOTE: This value can be accurately determined by subtracting the minimum from the maximum process value as recorded by the MAX/
MIN feature. See RESETTING MAXIMUM AND MINIMUM VALUES on page 12 for additional information.

SETTING THE SRO FAULT MONITOR
The SRO fault monitor senses the output of the relay and verifies that it is in the correct state. If the relay is closed when it should be open or open
when it should be closed this feature will turn off IAW, set the output current to < 3.6 mA attempt to turn off the SRO and SRO Status outputs. A
relay fault message will be displayed. This feature requires a connection to +VDC, -VDC or neutral (L2) from the load’s power supply. See wiring
connections for TB2 on page 8.
NOTE: The SRO fault monitor default is set to “OFF” from the factory and must be enabled by the user. Refer to the Programming Flowchart on page 19.
• Enter the Programming Mode and move through the program until SRO FAULT MON is scrolling on the display. Press the right gbutton.
• If OFF is displayed, press the left 2button to set fault monitoring to ON
• Press the right gbutton to activate SRO fault monitoring.
Setting the Filter
In some applications, it is desirable to “dampen” the Safety Relay Output response and prevent intermittent false trips due to pressure
spikes or other transient/isolated events. The Filter feature provides a software digital filter with a configuration time constant for sup-
pressing certain transient short-duration events.
Refer to the Programming Flowchart on page 19.
• Enter the Programming Mode (see page 10) and move through the commands until FILTER is scrolling on the display. Press the
right gbutton.
• The available selections are as follows
Pressure Models: OFF (Default) Temperature Models: 1/2 second
1/4 second 1 second
1/2 second 2 seconds
1 second
2 seconds
• Using the left 2button, select a time constant.
• Press the right gbutton to enter the time constant and return to main menu.
NOTE: The One Series typically responds to a process value change in less that 100 milliseconds when the Filter is set to off. Using this
feature can lengthen the overall response time of the One Series for certain types of process value changes (pressure spikes).
• A shorter delay setting provides a faster response but is less stable.
• A longer delay setting provides a slower response and is more stable.

IM_ONE_Safety-07

NOTE: Do not replace the One Series display module or pres-
sure sensor. Swapping these amongst devices will cause a
mis-match between the stored sensor calibration data and the
pressure sensor. For proper operation, the display module
serial number must always match the serial number inside the
enclosure (see Figure 18).
These serial numbers must match for proper operation.
DISPLAY MODULE CALIBRATION
SETTING THE SCALE
The 4-20 mA output is field scalable. The default setting is 100% of the sensor’s maximum range, where 4 mA represents minimum and 20 mA
is maximum range. If desired, both the 4 mA and 20 mA levels may be set independently to shrink or stretch the portion of the sensor’s range
represented by the 4-20 mA output.
• Setting the 4 mA portion of the scale (see Figure 17):
• Enter the Programming Mode (see page 10) and use the left 2button to move to the 4MA SET command.
• Press the right gbutton to select a positive or negative scale. POS is the default. Use the left 2button to change to NEG.
• Press the right gbutton to view and change the scale. Press the left 2button to increment the blinking digit. Press the right g
button to enter and move to the next digit. This process value must be between -3% and 25% of the sensor’s maximum range.
• Press the right gbutton to enter the new scale and return to the main menu.
• Setting the 20 mA portion of the scale (see Figure 17):
• Enter the Programming Mode (see page 10) and use the left 2button to move the 20MA SET command.
• Press the right gbutton to select a positive or negative scale. POS is the default. Use the left 2button to change to NEG.
• Press the right gbutton to view and change the scale. Press the left 2button to increment the blinking digit. Press the right g
button to enter and move to the next digit. This process value must be between 50% and 110% of the sensor’s maximum range.
• Press the right gbutton to enter the new scale and return to the main menu.
NOTE: Scaling the 4-20 mA output over a smaller portion of the sensor’s range does not the increase the accuracy of the proportional output. A
2:1 turndown is possible using these commands.
