SYMPTOM
POSSIBLE CAUSE
CHECK
CORRECTIVE ACTION
System shows no
sign of life.
No power to system.
Check fuses and main
disconnects.
Correct and replace main
fuse as necessary
See "Motor does not move at
all" below.
(page 11).
System blows main
Faulty wiring to transformer.
Check line voltage wiring.
tuse (tou mA)
—located on
Aquatrol panel
printed circuit
board (page 11).
Faulty transformer.
Check transformer as follows:
Switch off the unit and remove the
Aquatrol from subbase. Route 2
wires through a wiring knockout in
the subbase and connect them to
terminals D and 3. Connect the
free ends of the wires to a suitable
ac voltmeter. Replace Aquatrol on
subbase and switch unit on. Meter
should read approx. 24 Vac.
Remove wires from unit after
transformer test.
Replace Aquatrol if
necessary.
Panel powered,
LED's light, but no
power on output
terminals C or A.
Output fuse blown or faulty
wiring.
Check fuse and wiring.
Replace output fuse (see
page 11). Correct wiring.
Motor does not
move at all
(stopped in
midstroke).
Failure in motor.
Use function switch to check motor
action (positions 1 and 3). Use
voltmeter to check voltage at
motor.
Replace motor if
necessary.
No power to motor.
If line voltage is not supplied from
Aquatrol, check power supply.
Repair power supply as
necessary.
Component failure in panel.
Function switch-operates motor
but turning adjustment knobs does
not.
Replace panel.
Linkage is jammed.
Inspect linkage—operate
manually.
Repair linkage, valve
damper, or sequencer.
Loose connections.
