Controller
Status Description
Low/No Input Voltage
Check the input voltage to the controller. Measure the voltage between
L1 and L2 using an AC Voltmeter. This voltage should be greater than
190Vac.
Controller is in Program Mode
Check the position of the “RUN/PRG Jumper”. The “RUN/PRG Jumper” is
located in the upper lefthand corner of the controller. Refer to Figure 4.
Placing this jumper in “PRG” mode (Program Mode) allows the user to
update the controller’s software through the “Comm. Port”
(Communications Port). Consult the factory for details on updating the
controller’s software. When this jumper is in “RUN” mode (Run Mode),
the controller will operate normally.
If the controller is powered while in Program Mode, the status indicator
will not turn on. To return the controller to Run Mode turn the power off
to the controller and wait 5 minutes. Then move the “RUN/PRG Jumper”
to “RUN”. Apply power to the controller. The controller is now in
Run
Mode.
