Check the
incoming power.*

Check breaker first, then
check wiring coming
into operator.
The voltage should be
120 Vac or 240 Vac depending
on the application.

Check the AC power switch.

Is it ON?

Check the power
wiring connector.

Is it plugged into the correct
socket?

Check the transformer.*

Check the transformer voltage going into
the bridge rectifier (orange wires).
The reading should be 24 Vac (+/- 15%).
If not, replace the transformer.

Check the bridge
rectiﬁer.*

Check the voltage coming
out of the bridge rectifer
(red and black wires).The
reading should be 35 Vdc
(+/- 15%).
If not, replace the bridge
rectifier.

7

Check the control
board.

Try replacing the fuse on
the control board. If that
does not work, replace
the control board.

Check the batteries.*

Check the battery connections. Make
sure two 7AH batteries OR two 33AH
batteries are connected in series.
Check the voltage coming from each
battery by disconnecting the battery
from the operator. A fully charged
battery should read 12.8 to 13.3 Vdc per
battery. If not, replace the batteries.
