PBand PB 2should always be set thesame to achieve balanced control.6.Press [DISPLAY] to store the new settings and return to normal operation.CYCLE TIME: Multiplied by the controller output (0 to 100% Open or 0 to 100% Close) to determine the actual on time ofthe output relays. Faster actuators will require shorter cycle times to prevent excessive overshoot. Suggested cycle timesfor standard actuators are listed below.ActuatorCycle TimeB-C Medium Torque10 secondsB-C High Torque5 secondsDuff-Norton2 secondsChange cycle times, if required, by the following procedure:1.Press [SET UP] until the display reads SET UP TUNING.2.Press the [FUNCTION] key until the lower display reads CYC TI. The upper display will show the current cycletime setting.3.Use the] or ]keys to change the cycle time value.4.Press the[FUNCTION] once more until the lower display reads CYC2TI.5.Change cycle time 2 to the same value as cycle time 1.6.Press the[DISPLAY] key to store the new settings and return to normal operation.INPUT FILTER:The DC200E controller includes an electronic input filter which can be used to compensate fordisturbances at the pressure tap. If the displayed value is erratic even when the controller is in MANUAL and thedamper is stationary, set the input filter to 1 or 2 using the following procedure.
