Resetting Trip Count (Model 1XTXSW Only)
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 21.
• Enter the Programming Mode (see page 10)
• Press and release the left
2
button until RESET TRIP CNT1 appears on the display. Repeat these steps for RESET TRIP CNT2.
• Press the right
g
button. The recorded value of times the set point was reached (the trip count) will appear on the display.
• Press the right
g
button to clear (reset) the trip count to zero.
• Press the left
2
button 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 configuration time constant for suppressing certain
transient short-duration events.
Refer to the Programming Flowchart on page xx
• Enter the Programming Mode (see page xx) and move through the commands until FILTER is scrolling on the display. Press the right
g
button.
• 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
2
button, select a time constant.
• Press the right
g
button 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 (Model 1XTXSW Only)
The Trip Delay provides a configurable delay for SW1 and SW2 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 21.
• Enter the Programming Mode (see page 10)
• Press and release the left
2
button until TRIP DELAY1 scrolls on the display. Repeat these steps for TRIP DELAY2.
• Press the right
g
button. OFF will appear on the display.
• Press the left
2
button 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
2
button to increment the blinking digit.
• Press the right
g
button to move to the next digit.
• Press the right
g
button to enter the new Trip Delay value.
