d) Relays:
1. X10 (WV1 and WV2): If WV1 continues and WV2 does not energize, check for
115VAC between X10 relay terminal #4 (GY) to neutral (W) and X10 relay terminal
#2 (W/O) to neutral (W). If 115VAC is present at relay terminal #2 (W/O) and not
at relay terminal #4 (GY), check for 115VAC at relay terminal #8 (P). If 115 VAC is
present at relay terminal #8 (P) and not at relay terminal #4 (GY), replace relay.
If 115VAC is present at relay terminal #4 (GY) and not at relay terminal #2 (W/O)
and WV1 contines, clean or replace WV1.
2. X12 Relay (DV Lockout relay 1) and X13 Relay (DV Lockout relay 2):
If DV energizes (water owing down the drain) check for 115VAC at X12 relay
terminal #8 (GY) to neutral (W). If 115VAC is not present see "d)1. X10 (WV1 and
WV2)" above. If 115VAC is present, check X12 relay terminal #6 (Y) to neutral (W)
and #4 (P) to neutral (W). If 115VAC is not present from X12 relay terminal #6 (Y)
to neutral (W), check for 115VAC on X10 relay terminal #5 (V) and relay terminal
#3 (Y) to neutral (W). If 115VAC is present on X10 relay terminal #5 (V) and not on
relay terminal #3 (Y) replace X10 relay. If 115VAC is present on relay terminal #6 (Y)
and not on X12 relay terminal #4 (P) replace X12 relay. If 115VAC is present on
X12 relay terminal #4 (P), check for 115 VAC at X13 relay terminal #8 (P) to neutral
(W). If 115VAC is present, check for 115VAC at X13 relay terminal #2 (W/BK) to
neutral (W). If 115VAC is present at X13 relay terminal #2 (W/BK), replace
X13 relay. If 115VAC is not present on X13 relay terminal #2 (W/BK) and water is
going down the drain, clean or replace DV.
3. X11 (DV/HPT relay): If PM energizes during initial harvest, check X11 relay
terminal #8 (DBU) to neutral (W). If 115VAC is present, and CB LED 3 is off, replace
CB. If 115VAC is not present, check for 115VAC at X11 terminal #6 (R) to neutral
(W). If 115VAC is present and CB LED 3 is off, replace X11 relay. Check X11 relay
terminal #5 (W/BU) to neutral (W). If 115VAC is present, check X11 relay terminal
#8 (DBU) to neutral (W). If 115VAC is present on X11 relay terminal #8 (DBU) and
CB LED 3 is off, replace CB.
