9060 High Voltage Controller - Operation
The analog input signals are calibrated during
manufacturing. The following table lists the
analog input voltages corresponding to their
respective setpoints from 20kV to 90kV in 10kV
increments. The actual analog value can vary
slightly from unit to unit, but should be no more
than ±0.1V off the value listed below.

If the setpoint values are NOT matching
closely to the values listed in the table,
the unit may need recalibrated or re-
paired. Please contact your Ransburg
representative.
The 9060 Controller automatically trun-
cates the maximum setpoint value to the
maximum voltage allowed for the applica-
tor being used. Control signal increases
beyond the maximum voltage equivalent
will have no effect.

!
DO NOT attempt to use both analog
voltage and analog current at the same
time. The analog inputs are mutually ex-
clusive. Using both inputs simultaneous-
ly will damage the input circuit. Only one
analog input, current or voltage, can be
used at time to control the setpoint value.

Local/Remote Mode Selection
The local/remote mode selection signal is used
to determine when the unit should be in LOCAL
mode or REMOTE mode.
remain in the active ON state for the unit to
operate in REMOTE mode.
LOCAL/REMOTE MODE SIGNAL TIMING:
The local/remote mode signal hold time for a
mode change is 10 ms.
N O T E
The 9060 Controller is designed to pre-
vent false triggering when the unit chang-
es between LOCAL and REMOTE
modes. Following any mode change,
there is a 300 ms delay during which all
triggers are ignored.
Reset Signal
While in REMOTE mode, if a fault occurs, the
fault can be detected by the control system
using the fault relay contact outputs. If the fault
relay signal is active, the Reset Signal can be
used to clear the fault status. To clear a fault
using the reset signal, turn off the trigger signal,
then turn on the reset signal for approximately
10 ms to reset the fault.. Then turn off the reset
signal.
RESET SIGNAL TIMING:
The reset signal has a minimum hold time of 10
ms.
N O T E
There is a 5 second fault reset delay
timer that inhibits the triggering of high
voltage immediately after a fault reset.
The Reset button on the front panel can
also be used in REMOTE mode to clear a
fault condition as long as the front panel
lockout jumper is not installed.
Trigger Signal
The trigger signal is used to activate the High
Voltage output from the cascade.
