Pulse Rate Alarm (RATE)
Program the pulse rate display set point to trigger the alarm. The rate alarm deadband is
determined by the difference between set and reset points. Minimum deadband is one
display count. If set and reset points are programmed the same, output will reset one
count below set point.
Total or Grand Total Alarm (TOTAL, GRTOT)
Program total or grand total Set point. A pulse alarm will generate when the Set value is
reached by the total or grand total.
If the total/grand total is set for manual reset, this alarm will remain until the total/grand
total is reset to 0.
If automatic total/grand total reset is enabled, the output will generate an alarm for a
period of time programmed in ADVANCE  T RESET  TOTAL  AUTO T DELAY. After
this time delay, the total/grand total will reset to 0 and the alarm will clear.
If Out 1 and Out 2 are set for total or grand total alarm, the auto reset will be triggered on
the highest of the two alarm set points.
For details on setting the total or grand total automatic reset time delay, see
Total Reset (T RESET) on page 78.
Force On State (ON)
This alarm mode forces the output to be active, or on. This mode is primarily used to test
alarm systems.
Force Off State (OFF)
This alarm mode forces the output to be inactive, or off. This mode is primarily used to
test alarm systems.
Timer Output (TIMER)
The timer output produces a constant width pulse at a constant frequency. Program the
Period
(PERIOD) for one time period from 0.1 to 999999.9 seconds (time from the start of one
pulse to the start of the next pulse).
Program the On Time (TIME) for the active low pulse from .01 to 99999.99 seconds (pulse
width). The on time must be less than the delay time.
Select Start (START) to begin outputting the constant timed pulse.
Select Stop (STOP) to end outputting the constant timed pulse.
