CR pump control

Status Indicator
The Pump control status indicator on the Status/diagnostic screen (Figure 4.4) gives the
following indication – Pump Drive PCB trip.
The Trip Condition
The trip is set if the combined current load from both outputs exceeds 5A for more than 5
seconds.
Switching off the power supply to the system, waiting a few seconds, and then switching back
on should reset the fault. This is achieved by pressing the 'Reset' key in the Pump Control
PCB area of the Status screen.
Short circuit or damaged pump solenoid coils may cause the trip. Any solenoid resistance
below 2Ω should be regarded as suspect.
Other Faults
Check the fuse on the control board. The CR pump control PCB receives its 14V power
supply from the main transformer. This is protected by a 6.3A anti-surge fuse (FS1) on the
PCB (Figure 5.14).
