Cycle Time
This Tune mode parameter is used to select the on/off cycle time for time proportioning
outputs (Ct1 for Output 1 and/or Ct2 for Output 2). (See page 41, Section 4.5)
When using the Position Proportioning option, Ct1 must be selected for the stroke time of the
motor.
Deviation Band Alarm (Output 3)
This feature can be used to provide an indication that the process value has deviated outside
of a selectable deviation tolerance band value that strattles the setpoint. If in the Program
mode out3 is selected as 5, an assigned output will be off as the process value is within the
deviation band about the setpoint. The output will turn on if the process value falls below or
goes above the deviation band about the setpoint. The amount of the deviation band is
selected in the Tune mode parameter, dbAL.
If out3 is selected as 6, an assigned output will be on as long as the process value is within
the deviation band about the setpoint. The output will turn off if the process value falls below
or goes above the deviation band about the setpoint. The deviation band value is selected in
the Tune mode, dbAL.
Display Filter Factor
This Program mode parameter is used to dampen the process value displayed. The selec-
tions range from 1 through 20, the value represents the number of process scans that will be
averaged for the display value. Factory default is 1, no filtering.
