The PCM operating range is factory set according to the specific model. The operating
range can be changed to convert a PCM to any of four available operating ranges without
purchasing another model.
The operating range is converted by changing the position of the jumpers on the printed
circuit board located under the PCM’s cover.
Illustration A.
The PCM is equipped with two
jumpers that are positioned over the pins labeled 3, 2, 1.
Illustration B.
To change the time range:
1.
Unplug the PCM power cord from the input power supply.
2.
Remove the cover and reposition the jumpers to correspond with the desired
operating range.
Refer to Interchangeable Operating Range Settings below.
3.
Replace the PCM cover.
4. IMPORTANT!
Update the PCM data label to represent the converted model and
operating range for accurate sizing.
