10. Use maintenance menu to turn on distillate pump while monitoring LED corresponding to SSR 5 on PCB3.
Does LED come on?
YES Go to step 11.
NO Go to TYPICAL AC OUTPUT SIGNAL FAULT (WP 0104 00).
11. Use maintenance menu turn on distillate pump while checking for >100 VAC between terminal (12) on SSR
PCB3 and TB1 terminal (N).
Is >100 VAC present?
YES Go to step 12.
NO Go to TYPICAL AC OUTPUT SIGNAL FAULT (WP 0104 00).
12. Use maintenance menu turn on distillate pump while checking for >100 VAC between distillate pump
contactor terminals (A1) and (A2).
Is >100 VAC present?
YES Go to step 13.
NO Go to step 18.
13. Use maintenance menu to turn off distillate pump then check for >200 VAC across distillate pump contactor
input terminals (L1 and L2), (L1 and L3), and (L2 and L3).
Is >200 VAC present?
YES Go to step 14.
NO Go to step 22.
14. Use maintenance menu to turn on distillate pump then check for >200 VAC across distillate pump contactor
output terminals (T1 and T2), (T1 and T3), and (T2 and T3).
Is >200 VAC present?
YES Go to step 15.
NO Replace distillate pump contactor (WP 0220 00).
15. Use maintenance menu to turn on distillate pump then check for >200 VAC across distillate pump overload
relay output terminals (T1 and T2), (T1 and T3), and (T2 and T3).
Is >200 VAC present?
YES Go to step 16.
NO Replace distillate pump overload relay (WP 0221 00).
16. Position SW2 then SW1 to OFF.
17. Check wiring and connections between overload relay and distillate pump.
Are connections OK?
YES Replace distillate pump (WP 0162 00).
NO Repair as necessary.
18. Position SW2 then SW1 to OFF.
