11: Condition
Blank/Bad On-Pump Display
Check voltage on mains connector. If voltage is
between 200-250VAC then go to 11B; if below or
0VAC then correct supply and check breaker.
Inspect harness
Verify the wiring harness is connected snugly
and inspect wires for damage. If damaged,
replace drive; If not, go to step 11C.
Verify pump power
Step 11A Step 11B
When a display is completely blank, typically the pump is not powered; this can
be caused by a tripped breaker or possibly related to external automation.
