9060 Cascade Low Voltage Controller - Operation

Analog Setpoint Control
The analog control signals are the dominant
setpoint control signals. When one of the
signals is present, it will override tripleset
setpoint control when the minimum analog
control signal value is reached. The minimum
signal required is the equivalent to 20kV. While
analog control is used, the control signal can be
adjusted between control signal’s minimum and
maximum values to adjust the output.
ANALOG SETPOINT SIGNAL TIMING:
The analog “setpoint” signal minimum hold time
is 80 ms to allow for analog sampling. Output
will begin to adjust after the setpoint has been
updated.
ANALOG VOLTAGE SIGNALING:
Control Signal Range:
0 - 10V
Minimum Signal (20kV): 2.0V
ANALOG CURRENT SIGNALING:
Control Signal Range:
0mA - 20mA
Minimum Signal (20kV): 4mA
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 analog setpoint control signal drops
below the minimum setpoint value, tripleset
selection will automatically take control
again. This will cause the setpoint to return
to the last tripleset value that was used.
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. This signal must
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.
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.

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.
