136 UDC2300 Controller Product Manual 12/00
12.2.44 I MIN or I RPM (RESET - INTEGRAL TIME)
This prompt is part of the Tuning Set up group.
I MIN = RESET TIME IN MINUTES / REPEAT
I RPM = RESET TIME IN REPEATS PER MINUTE
RESET RATE or INTEGRAL TIME adjusts the controller’s output in accordance with
both the size of the deviation (SP-PV) and the time it lasts. The amount of the corrective
action depends on the value of Gain. The Reset adjustment is measured as how many
times proportional action is repeated/minute.
Used with control algorithm PID-A.
Defined as “HEAT” Reset on Duplex models for variations of Heat/Cool applications.
The selection of minutes per repeat or repeats per minute is made in the Control
parameters group under prompt “MINRPM.”
Range of Setting: 0.02 to 50.00
12.2.45 I2 MIN or I2 RPM (RESET2 - INTEGRAL TIME)
This prompt is part of the Tuning Set up group.
I2 MIN = RESET IN MINUTES / REPEAT
I2 RPM = RESET IN REPEATS PER MINUTE
RESET RATE 2 or INTEGRAL TIME 2 adjusts the controller’s output in accordance
with both the size of the deviation (SP-PV) and the time it lasts. The amount of the
corrective action depends on the value of Gain. The Reset adjustment is measured as how
many times proportional action is repeated/minute.
Used with control algorithm PID-A.
Defined as “COOL” Reset on Duplex models for variations of Heat/Cool applications or
for a Second Set of PID constants.
The selection of minutes per repeat or repeats per minute is made in the Control
parameters group under prompt “MINRPM.”
Range of Setting: 0.02 to 50.00
12.2.46 INCRMT (TIME COUNT INCREMENT)
