Instruction Manual
63
Rate Alarm (
rate
)
Program the rate
set point
to trigger the alarm. 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 to-
tal/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
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
