CONTINUOUS OPERATION SHOULD NOT EXCEED THE DESIGNATED OVER RANGE PRESSURE OR WORKING PRESSURE RANGE STATED WITHIN
THE LITERATURE AND ON DEVICE NAMEPLATE.
Over Range Pressure: The maximum pressure to which a pressure sensor may be continuously subjected without cause damage and maintaining
set point repeatability.
Max Working Pressure: The maximum that can be applied to both process ports simultaneously without affecting sensor performance.
The One Series electronic switch product line is based on an all-solid-state electronic module that incorporates a microprocessor. The com-
bination of features like no moving parts and IAW™ self-diagnostics provide a highly reliable, accurate and repeatable monitor for detecting
pressure and temperature thresholds which once reached, can make intelligent switch decisions based opon retained settings and current
conditions. The One Series monitors its own health and reports the status locally through the IAW™ (I Am Working) feature that provides a
solution to the “blind device” issue common with mechanical switches. You will always know the health status of the One Series.
The One Series is also very rugged, featuring a Type 4X, weather-tight enclosure suitable for harsh environments and hazardous (Class I,
Division 1) locations. The 0.5% accuracy rating is maintained over a very wide -40°C to +70°C operating range using active temperature
compensation. Repeatability is 0.1% of full range while the switch set point and deadband (hysteresis) is fully programmable over the entire
range of the sensor. Reaction time for the One Series to a process change is typically 100 mS or less.
2-WIRE SIMPLICITY (MODEL 1XSWLL AND 1XSWHL)
The One Series 2-Wire electronic switch is designed to operate on discrete input leakage current. The microprocessor-based One Series is the
only switch to operate and switch over a single pair of wires, similar to a traditional mechanical switch. It combines the simplicity and low cost
features of a switch and the reliability features found in a transmitter and without the need to provide additional wiring.
• Models 1XSWLL and 1XSWHL are designed to work with most Programmable Logic Controller (PLC) or Distributed Control System (DCS)
discrete inputs and some interposing relays. When open, the switch draws 750 µA (max); when closed, the switch sinks or sources 0.1
A maximum.
I Am Working (IAW™)
The One Series also contains UE’s patented IAW™ self-diagnostic software. On a continuous basis, the IAW™ algorithm checks for proper opera-
tion, 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 the control system and used to detect normal, tripped, and fault conditions. IAW™ self-monitors, searching for possible faults, both
within the instrument and in the overall system (see Fault Codes, table 4, page 16). In the event of a detected fault, the One Series will attempt to
display the fault details and provide remote electrical indication by opening (turning off) the IAW™ Output. In the case of certain micro-controller
faults, the revolving arrow may freeze or go out; indicating locally that a failure exists.
DISPLAY FEATURES AND DIAGNOSTICS
The One Series features a large, easy to read LCD display (see Figure 1). It is used for three main purposes: process indication, programming of
key features 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 110% of the full
scale range noted on the nameplate.
• 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
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”. 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.

PART I - MOUNTING
FLAMEPROOF, NON-INCENDIVE, INTRINSIC SAFETY - 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 19.
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.
Mount the device using the four (4) 1/4” clearance holes in the enclosure base. Plumb sensor to the process port. See page 19 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 HEX WHEN MOUNTING THE
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 12 FOR ADDITIONAL
INFORMATION).
PROCESS CONNECTIONS AND SENSOR FOR FLAMEPROOF, NON-INCENDIVE AND INTRINSIC
SAFETY INSTALLATIONS
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
FAULT CONDITIONS
In the case of a fault condition, the display may indicate the following:
If the IAW™software detects a fault outside of the micro-controller, and can still operate, it will display an error message.
If the fault is one which affects the micro-controller or the display, the revolving arrow around “IAW” will either freeze or go out.
If it is a failure of the power supply or the wiring, the display will go blank.
(See Fault Codes, page 16 for a complete description of fault diagnostics.)
Please refer to the product technical brochure for product specifications. Product technical brochure may be found at www.ueonline.com.

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. 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 20.

WIRING DIAGRAMS - Model 1XSWHH
Model 1XSWHH requires 70 – 240 VAC @ 0.015 A external power supply for each device. Power for all One Series functions are provided by this
power supply connection at TB2, terminals C (L1/H) and D (L2/N). Connections for the programmable solid state relay switch are made at TB2
terminals A and B. (refer to table 2, page 6 and table 3, page 8).
The wiring diagram below (Figure 9) provides a view inside the One Series base enclosure with the display module removed. TB2 is located there.
All models include a separate IAWTM switched output located at TB3 on the back of the display module. This signal provides the health status of
the One Series and is normally closed. When open, this signal provides an indication that IAWTM has detected a fault condition. Monitor this signal
by connecting it to the discrete input of a PLC or DCS. The IAWTM wiring connection is not required if remote health status of the One Series is not
used.
NOTE: The solid state relay switch in model 1XSWHH has a minimum load requirement of 0.150 A making it incompatible with control system
inputs. Do not exceed the maximum switch ratings (see table 2, page 6) or permanent damage to the One Series may result.

INTRINSIC SAFETY WIRING DIAGRAMS - MODEL 1XSWLL
(Use Class 2 or SELV Power Supply Only)
Model 1XSWLL is intended for direct connection to a PLC or DCS discrete input, or other suitable load (see graph 1, page 15). Power is
obtained and the discrete switch signal is provided by the same two-wire connection. Polarity must be observed. (refer to Table 2, page 6)
for switch ratings.
DO NOT CONNECT MODEL 1XSWLL DIRECTLY TO A POWER SUPPLY WITHOUT A SUITABLE LOAD IN SERIES WITH THE
SWITCH.
For 1XSWLL models, only one conduit opening is required. The unused conduit opening must include an explosion-proof/flameproof plug,
made from a corrosion-resistant material, suitable for all gas and dust groups as listed on the nameplate. Blanking elements from factory
have been tested with the enclosure as an assembly and carry no markings.
SELECTING AN INTRINSIC SAFETY BARRIER (Model 1XSWLL)
For Intrinsically-Safe (I.S.) installations, please reference the Control Drawing UE 62174–64 for Intrinsic Safety entity parameters and wiring
information (https://www.ueonline.com/support/product-drawings/). Model 1XSWLL must be wired to an approved I.S. galvanically isolated
barrier for Zone 0 EPL Ga and Class I, Division 1 classifications. The information provided is for reference only and is intended to act as a
guide in the selection of a suitable I.S. Barrier.
SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.
Installation of Intrinsically-Safe circuits must be performed in accordance with the requirements of the government and/or other local
authority having jurisdiction. System components and installation methods must be approved by the appropriate recognized approval
authority.
There are two general types of I.S. Barriers, shunt diode (passive) safety barriers and transformer isolated barriers. Shunt diode safety
barriers are not recommended for use with model 1XSWLL.
Transformer Isolated Barriers:
Due to the unique method by which the model 1XSWLL operates, a specifically designed isolated barrier must be used. Any safety barrier
that adheres to NAMUR standard EN 60947-5-6 for proximity and dry contact switches may be used to achieve intrinsic safety with the One
Series model 1XSWLL.
Recommended NAMUR standard transformer isolated intrinsic safety barriers:
Pepperl+Fuchs models KCD2-SR-Ex1.LB and KFD2-SR2-Ex1.W.LB
Figure 4 (page 6) shows a typical wiring scheme depicting model 1XSWLL connected to a programmable logic controller (PLC), distributed

Part III - PROGRAMMING
Tools Required: Programming Flowchart, page 18
Programming of the One Series is accomplished using the two buttons on the faceplate (labeled 2and g- See Figure 10). Stepping
down through the main menu using the left 2button, you can access the various commands of the One Series 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 18 shows the entire programming commands menu structure. Before removing the enclosure cover,
please read the instructions on page 5. The One Series programming menu is a single direction loop, 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 and then re-enter the program and step through to the appropriate feature. If you are in a Submenu, you will need to
continue to the beginning 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 will remove itself from service (go offline). All outputs are set to the fail safe
state and the One Series ignores process variable input from the process sensor. The IAW™ Output signal will open. The switch output
failsafe state will be based on the programmed operating mode of the switch. For example, the failsafe state for “Open on” modes is
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 18 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 One Series 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 program 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 programmer to the Save Changes menu location, which is only possible at menu
actions indicated by an asterisk (*) on the Programming Flowchart, found on page 18.
NOTE: It is also possible to exit the Programming Mode by repeatedly pressing the left 2button from any program command until the
Save Changes menu location is reached.
Saving Programming Changes
When changes have been made to the program 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 program 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 allows the units of measure to be set in the field. The default units are pounds per square inch (PSI) for pressure models
Figure 10

IM_1XSW-02
www.ueonline.com
10
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 and Plug Port values are recalculated for the newly selected units of measure.
Setting the Switch Mode, Set Point and Deadband
Please refer to the Programming Flowchart, page 18.
• Enter the programming mode (see page 9).
• 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.
The One Series has six available modes of operation
OPEN RISE - Switch opens on rising process values that exceed the set point.
OPEN FALL - Switch opens on falling process values that drop below the set point
OPEN WINDOW - Switch opens when process values go outside programmed limits specified by set point high and set point low.
CLOSE RISE - Switch closes on rising process values that exceed the set point.
CLOSE FALL - Switch closes on falling process values that drop below the set point.
CLOSE WINDOW - Switch closes when process values go outside programmed limits specified by set point high and set point low.
Note: “OPEN” Modes are recommended in safety applications where a DTT (De-energize to Trip) output is required. This ensures that the switch
output will go to the fail safe state in the event of a power loss or line break. The IAW™ output always operates in DTT mode.
Please use the Switch Decision Logic (Figure 11, page 11) for help with setting the appropriate switch 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 opens or closes the switch. 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 resets the switch, returning it to the normally
closed or open 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 Switch will open as pressure rises
to 100 and close (reset) as the pressure falls to 90.
• Example 2: If the Control Mode is CLOSE RISE and the set point is 100 and the deadband is 10, the Switch will close as pressure rises
to 100 and open (reset) as the pressure falls to 90.
• Example 3: If the Control Mode is OPEN FALL and the set point is 100 psi and the deadband is 10, the Switch will open as pressure
falls to 100 psi and close (reset) as pressure rises to 110 psi.
• Example 4: If the Control Mode is CLOSE FALL and the set point is 100 psi and the deadband is 10, the Switch will close as pres-
sure falls to 100 psi and open (reset) as pressure rises to 110 psi.
NOTE: Deadband should be set wide enough so that frequent or rapid switch cycling (chatter) does not occur but narrow enough to satisfy
the process conditions. A Deadband value of zero is undefined and, therefore, not permitted.

Resetting the Maximum & Minimum Values
The One Series continuously captures the readings from the sensor and stores one minimum and maximum value since the last time they were
reset. The values can be viewed at any time by removing the enclosure cover and pushing the left 2button. The display will scroll the values and
then return to the Process Display mode.
To reset the values, enter the Programming Mode (see page 9). 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 9), the values will be reset to the cur-
rent reading and begin recording again.

ADVANCED FEATURES
NOTE: No initial programming of these features is required. The default for these advanced commands is zero or off.
Adjusting Display Offset
The One Series 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.
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 18.
• 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 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 18.
• Enter the Programming Mode (see page 9) 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_1XSW-02
www.ueonline.com 13
NOTE: To return to factory calibration settings, enter all zeros for both SPAN and OFST.
Setting the Latch Mode (Manual Reset)
The switch can be configured to latch when the set point is reached. Refer to the Programming Flowchart on page 18.
• 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 Switch changes state when the set point is crossed and
remains latched until the Switch is manually reset by the user or the One Series is power cycled.
When latched, the display will read MAN RSET.
To Reset the Latch
• Enter the Programming Mode (see page 9). 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.
NOTE: Interrupting power to the One Series will also reset the latch.
SETTING THE PLUGGED PORT FEATURE
The One Series 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, indicating a fault. Refer to the
Programming Flowchart on page 18.
• 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 11 for additional information.

Resetting Trip Counter
Trip Count provides information that may be useful for troubleshooting a process. Each time the set point is reached, the trip count is
incremented by 1, up to 9999, where it will automatically return to 1. Trip Count is always on and can be manually reset to zero at any
time by following these steps.
Refer to the Programming Flowchart on page 18.
• Enter the Programming Mode (see page 9)
• Press and release the left 2button until RESET TRIP CNT appears on the display
• Press the right gbutton. The recorded value of times the set point was reached (the trip count) will appear on the display.
• Press the right gbutton to clear (reset) the trip count to zero.
• Press the left 2button to retain the trip count value without resetting.
Setting the Filter
In some applications, it is desirable to “dampen” the switch 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 programmable time constant for suppressing certain
transient short-duration events.
Refer to the Programming Flowchart on page 18
• Enter the Programming Mode (see page 9) and move through the program 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.
Setting the Trip Delay
The Trip Delay provides a programmable delay for the switch with a range of 0 – 999.9 seconds. Zero seconds is the factory default.
When the set point is reached, the switch trip will be delayed by the number of seconds entered into the Trip Delay command using the
following steps.
Refer to the Programming Flowchart on page 18.
• Enter the Programming Mode (see page 9).
• Press and release the left 2button until TRIP DELAY scrolls on the display.
• Press the right gbutton. OFF will appear on the display.
• Press the left 2button to select ON. The Trip Delay value in seconds (default = 000.0) will appear on the display with the left digit
blinking.
• Press the left 2button to increment the blinking digit.
• Press the right gbutton to move to the next digit.
• Press the right gbutton to enter the new Trip Delay value.

TROUBLESHOOTING
The switches contained in the One Series are electronic. The on/off switch signal is produced by a transistor or a solid-state relay, depending on the
One Series model. Electronic switches cannot be properly tested with an ohmmeter. Instead, measure the voltage drop across the switch connected
to the intended load to determine if it is open or closed. A properly functioning One Series electronic switch will exhibit the following voltage levels
(see Table 5):
