The 9040 Printed Circuit Board (PCB) contains a
safety circuit that prevents high voltage from being
present at the applicator if the high voltage trigger
device (pressure switch, PC contact, etc.) has not
been triggered. If a failure mode should occur that
would attempt to send high voltage to the applicator,
even though the high voltage trigger has not been
activated, the PC board will shut down and enter
an overload condition. If repeated overloads occur,
every time the overload reset button is pushed,
open the cabinet door and see if the red LED (see
Figure 5, in the "Maintenance" section for
LED1location) on the PC board lights for about 2
seconds after pushing the reset button. If it does,
the PC board has failed and should be replaced.

Power supplies for applicators shipped
from the factory with the overload circuit
ON. Automatic applicators typically have a
fixed distance between electrode and target
and thus it is not likely that the spray appli-
cator would come into close proximity with
the part during normal use. If it should, then
it is desired that an overload occur to alert
maintenance so that the condition can be
corrected. Additionally, since there is no
operator with automatic applicators, the
overload circuit is required to alert mainte-
nance when failed parts may be causing
the spray applicator to operate at less than
optimum performance.

Lighting of the yellow overload/reset lamp indicates
that an overload condition has occurred. The
overload circuitry is integral to the power supply
and is factory calibrated and sealed. It allows
normal operation, testing, and maintenance. It will
only activate if the spray applicator current exceeds
the preset limit as a result of component (barrel,
transformer, cable) failure or improper applicator
to target distance. If the overload should trip,
locate and correct the problem. Then reset the
overload by pushing the reset switch in, or turning
the ON/OFF switch OFF and back ON again.
The overload feature can be turned ON or OFF by
moving jumper JP5 on the main PC Board (see
Figure 5, in the "Maintenance" section for location
of JP5). To turn the overload circuit OFF, position
jumper JP5 so that it covers (shorts) pins 1 and 2.
To turn the overload circuit ON, position jumper
JP5 so that it covers (shorts) pins 2 and 3.
