9040 Cascade Low Voltage Control Unit - Operation
Automatic applicators, however, typically have a
fixed distance between electrode and target and
thus it is not likely that the spray applicator 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 may be corrected. Additionally, since
there is no operator with automatic applicators,
the overload circuit is required to alert maintenance
when failed parts may be causing the applicator
to operate at less than optimum performance.
When turning the overload circuit ON for applicator
units it may be necessary to adjust the setpoint at
which overload occurs. If so, contact your
authorized ITW Ransburg representative for
assistance.

The 9040 Main PC board contains a safety circuit
that prevents high voltage from being present at
the applicator if the high voltage trigger device
(flow switch, 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 the
control unit repeatedly overloads even though the
high voltage trigger has not bee activated, the main
PC board has failed and should be replaced.

The yellow cable fault/hook OFF LED will light
whenever the low voltage signal to the applicator
is open circuited. This will occur if the cable is
not connected or if the cable becomes damaged
such that power cannot be transmitted to the
applicator. With applicators having hook
transformer mounted ON/OFF switches, the cable
fault/hook OFF indicator will also light when the
switch is placed in its OFF position.
> Because of the manner of high voltage
triggering employed in the REM applica-
tor, the Cable Fault/Hook OFF Indicator
will not function if either wire to the reed
switch, located in the applicator handle,
becomes open circuited (such as when
the cable is disconnected or completely
cut through).
