“corrected” each time the controller drives the motor to one of its stops (0 %
or 100 %). It avoids all the control problems associated with the feedback
slidewire (wear, dirt, noise). When operating in this algorithm, the estimated
“OUT” display is shown to the nearest percent (that is, no decimal).
Other prompts affected: D BAND
12.2.24 CSRATO (COMPUTER SETPOINT RATIO)
This prompt is part of the Communications Set up group.
RATIO—Computer setpoint ratio
Range of Setting: -20.0 to 20.0
12.2.25 CYC T1 or CT1 X3 (CYCLE TIME - HEAT)
This prompt is part of the Tuning Set up group.
CYCLE TIME (HEAT) determines the length of one time proportional output relay cycle.
Defined as “HEAT” Cycle time for Heat/Cool applications.
CYC TI—Electromechanical relays (seconds)
CTIX3—Solid state relays (1/3 seconds)
Cycle times are in either second or 1/3-second increments depending upon the
configuration of RLY TY in the Output Algorithm Set Up group.
Range of Setting: 1 to 120
ATTENTION
If 1/3 second increments are used, 1 = .33 seconds and 120 = 40 seconds.
