Use the ‘+’ and ‘-’ buttons to increase and decrease the amount of cycles respectively. Press the ‘OK’ button again to set the counter value.

The Option Modes allow for the changing of some variables, which may extend filter life or increase performance on non-standard applications. If the settings are changed, the defaults are as follows: Option Mode: ShutDown Pls #: 05 Option Mode: Shutdwn delP: 3.0 Option Mode: Run Pls delP: 7.0 Option Mode: Alarm delP: 9.9 Optional Variable Frequency Drive (VFD) A Variable Frequency Drive (VFD) can be ordered to operate the motors in place of the contactors and overload. This device operates by varying the frequency used to drive the motor; this causes the motor to run at a slower speed and shifts the blower curve. By bringing in the pressure from a differential pressure sensor, the speed of the drive is correlated to the filter loading.
