terminals (from left-to-right):
“
VALVE
” – Left solenoid
“
IN
” – Incoming power
“
VALVE
” – Right solenoid
9.8.3
Use a Voltmeter to measure
the DC voltage across each
set of “
VALVE
” terminals.
Continue to measure for up to
45 seconds if no voltage is
initially measured.
The voltage should measure:
•
53 VDC
for the P1500W2, P1500W2LP & P1500W2HP models
•
106 VDC
for the P1502W2, P1502W2LP & P1502W2HP models
9.8.4
Close Front Panel.
If the voltage does not measure as indicated above, this is an indication that the
Cycle Timer is defective and should be replaced. See sections 11.3 for part detail
and 11.5 for ordering information.
