TABLE 3 TROUBLE-SHOOTING GUIDE
PROBABLE CAUSE SUGGESTED ACTION
Pull on chain slightly in each direction in order to
disengage the chain hoist and return the operator
to electrical operation. Check switch otherwise.
Reset the overload protection: press reset button
located on the side of the unit for a single phase
operator. For a three phase operator, the thermal
switch is inside the motor, let motor cool and
restart operator. Is the door unbalanced?
Reset circuit breaker.
Replace fuse. If control circuit fuse keeps blowing:
Disconnect all external devices. Leave power
terminals connected. Run the operator artificially
by using jumpers and shorting out the appropriate
terminals as indicated in the Start-Up and Testing
Guide. Then reconnect the various external
devices one by one until you find the one causing
the short to ground.
OR: If you have an ohm-meter, use it to check all
incoming wires for continuity to ground. The meter
should read infinity in all instances. If there is
conduction between any control circuit wire and
ground, this indicates a leak to ground and this is
why the control circuit fuse blows when power is
applied.
In some cases, the trouble is intermittent: i.e. the
fuse only blows at certain times. This problem is
more difficult to detect, but again: disconnect all
wires going to external devices, and run the
operator: if the fuse does not blow, this indicates
that the trouble resides outside the operator.
