OFF TIME DELAY
0.0 to 599.9 Sec
Enter the time value in seconds that the output is delayed from turning
off after the trigger point is reached. A value of 0.0 allows the meter to
update the output status per the response time listed in the Specifications.
Enter the reset action of the output. See figure for
details.
Auto = Automatic action; This action allows the output to automatically
reset off at the trigger points per the Setpoint Action shown in Setpoint
Output Figures. The “on” output may be manually reset (off)
immediately by the front panel RST button or user input.The output
remains off until the trigger point is crossed again.
LAtCH = Latch with immediate reset action; This action latches the output
on at the trigger point per the Setpoint Action shown in Setpoint Output
Figures. Latch means that the output can only be turned off by the
front panel RST button or user input manual reset, or meter power
cycle. When the user input or RST button is activated (momentary
action), the corresponding “on” output is reset immediately and
remains off until the trigger point is crossed again. (Previously latched
alarms will be off if power up Display Value is lower than setpoint
value.)
L-dLY = Latch with delay reset action; This action latches the output on
at the trigger point per the Setpoint Action shown in Setpoint Output
Figures. Latch means that the output can only be turned off by the
front panel RST button or user input manual reset, or meter power
cycle. When the user input or RST button is activated (momentary
action), the meter delays the event until the corresponding “on” output
crosses the trigger off point. (Previously latched outputs are off if
power up Display Value is lower than setpoint value. During a power
cycle, the meter erases a previous L-dLY reset if it is not activated at
power up.)

Setpoint Output Reset Actions
This parameter enables the RST button or user input to reset the
output when the display is reset.
Note: For this parameter to operate, the RST button or User Input
being used must be set to dSP and the Input value must be displayed. If
these conditions are not met, the output will not reset.

OUTPUT RESET WITH DISPLAY RESET
YESNO
When YES, the output is disabled (after a power up) until the trigger
point is crossed. Once the output is on, the output operates normally per
the Setpoint Action and Output Reset Action.

ON TIME DELAY
Enter the time value in seconds that the output is delayed from turning
on after the trigger point is reached. A value of 0.0 allows the meter to
update the output status per the response time listed in the Specifications.

HYSTERESIS VALUE
1 to 59999
Enter desired hysteresis value. See Setpoint Output Figures for visual
explanation of how setpoint output actions (balanced and unbalanced)
are affected by the hysteresis. When the setpoint is a control output,
usually balanced hysteresis is used. For alarm applications, usually
unbalanced hysteresis is used. For unbalanced hysteresis modes, the
hysteresis functions on the low side for high acting setpoints and
functions on the high side for low acting setpoints.
Note: Hysteresis eliminates output chatter at the switch point, while time
delay can be used to prevent false triggering during process transient
events.
