Description
The Voltage Feedback Fault indi-
cates the cascade drive signal is
not present. It typically occurs
when high voltage is triggered.
The Boot Fault indicates that an
active trigger signal was detected
during the start-up sequence.
The DI/DT Overload Fault indi-
cates that the change in current
has exceeded the user specified
current limit (sensitivity, SE), dur-
ing the user selected time interval
(Sample Time, SA).
Solution
1. Turn off the voltage controller and remove
the high voltage cable from the voltage
controller.
2. Turn on the power, wait for 0µA display,
and place HV test jumper J8 in shorted po-
sition. If the UC fault occurs, send the high
voltage controller in for repair. If no fault
occurs, continue.
3. The high voltage cable may have failed.
Replace the high voltage cable and re-test.
4. Send applicator unit in for repair.
1. Turn off the voltage controller.
2. Ensure test jumper J8 is not shorted on
both posts. Ensure that the gun trigger is
not pressed or for remote units that the re-
mote trigger input signal is not active.
3. Turn on the voltage controller to verify that
a trigger signal is not present and that the
unit enters the 'ready' state.
4. Send the voltage controller in for repair or
contact technical support.
1. Ensure that the target and no other object
is approaching the applicator within the
minimum safe distance during applica-
tion. Reset the fault and re-test operation.
2. Using the parameter adjustment mode,
adjust the sensitivity and sample time inter-
val configuration values for DI/DT. Re-test
operation for different values.
3. Contact technical support for further assis-
tance.
