Pump 1 Does Not Work!
If Pump 1 is not working, carry out the following tests to correct the
problem:
To increase the life of the relay, we use a "snubber" circuit on the pump relay.
With this type of circuit, if no pump is connected to an output and relays are open,
the voltmeter will continue reading around 60 volts. This is normal.
It is important to measure voltage when pump is connected to pack.
Power must remain On.
2• Verify if "Pump 1" indicator appears
on keypad display when you press
Pump 1 key.
If "Pump 1" indicator does not appear,
check low level programming first
(see Low Level Section).
1• Check for an error condition on
keypad display. If yes, refer to
specific section indicated by error
condition.
4• If "Pump 1" indicator appears on
keypad display when Pump 1 key
is pressed, verify if Pump 1 works
in any of the speeds.
3• If "Pump 1" indicator does not
appear, use a spare keypad to
verify if keypad is defective.
If it is, replace keypad.
If not, replace board.
