9060 Cascade Low Voltage Controller - Introduction
15 CP-13-02.2
Any control signal increases that would push
the setpoint beyond this value will have no
effect. This is done to protect the applicator
from adverse damage.
Analog Voltage Signal
The analog voltage signal (3TB-3) is an input
control signal that adjusts the KV setpoint
scaled relative to the voltage signal applied.
The allowable range for the voltage control
signal is 0-10V. The minimum signal re-
quired to override the KV setpoint control is
2.0V.
Analog Current Signal
The analog current signal (3TB-2) is an input
control signal that adjusts the KV setpoint
scaled relative to the current signal applied.
The allowable range for the current control
signal is 0mA-20mA, with the minimum
required to override the KV setpoint being
4mA.
Analog Common Signal
The analog common signal (3TB-4) is the
connection for the common reference (-) of the
analog signal source. It is used as the com-
mon for both the voltage and current signal.
Although the allowable range for the
analog current signal does include 0mA-
3mA, it will normally be listed as 4-20mA
as the 0-3mA portion of the range is insuf-
ficient to override KV setpoint control.

Analog Output
The 9060 Cascade Low Voltage Controller
provides a single analog output signal that can
be used for monitoring the current output. This
output can be used for simple monitoring or it
can be used by the control system to allow for
closed loop analog setpoint adjustment.
Analog Current Signal
The analog current signal (3TB-5) is a scaled
version of the actual feedback current. The
real feedback current is in µA where as the
current signal provided at 3TB-5 is in mA to
make it easily integrated with common sys-
tems like PLCs.
Relay Contact Outputs
The relay contact outputs are the HV On and
Fault outputs that were previously described in
the Signal Interface - Local Mode section.
Their descriptions are duplicated here for
completeness.
High Voltage On ( Relay Output,
Dry Contact )
The “HV on” signal (4TB-3) is available in both
LOCAL and REMOTE modes. This signal,
being a relay controlled signal, can be config-
ured as either an AC or DC signal using the
Relay Common Input as the signal source.
For information regarding the relay contact
voltage ratings, please refer to the “Relay
Output Contacts” portion of the “Installation”
section of the manual. This relay signal is
activated when the High Voltage cascade is
turned on.
Fault ( Relay Output, Dry Contact )
The “Fault” signal (4TB-1) is available in both
LOCAL and REMOTE modes. This signal,
being a relay controlled signal, can be config-
ured as either an AC or DC signal using the
Relay Common Input as the signal source.
For information regarding the relay contact
voltage ratings, please refer to the “Relay
Output Contacts” portion of the “Installation”
section of the manual. This relay signal is
activated when a Fault Condition or Overload
Condition has faulted the 9060 Controller.
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.
