Overrun Timer
(See Figure 7-13). All versions of the PLC program contain an Overrun Timer that will shut the com-
pressor off after a certain amount of continuous running. The length of time can be set to 5 hours (fac-
tory standard) or from 6 to 24 hours in two hour increments. It can also be bypassed entirely eliminating
the Overrun Timer.
Active Power’s default setting is “Bypassed
”

Adjusting the Overrun Timer
(See Figure 7-15). The setting is determined by rotating the Overrun Timer Adjustment.
1. Begin by gently rotating the Overrun Timer Adjustment fully Counter-Clockwise to 9 o’clock. If it
is desired that the compressor shut down after five hours of continuous running, then leave it at this
position.
2. If it is desired that the compressor shut down after six hours or more hours of continuous running,
rotate the Overrun Timer Adjustment Clockwise .
