Triggering
High voltage is actuated by the presence of an
active trigger signal. In LOCAL mode, this is
normally accomplished by pulling the trigger of
the handgun to start the flow of atomizing and
fan control air through the applicator. When the
applicator is triggered, an air flow switch (see
Accessory table) is activated, and the trigger
signal is issued to the 9060 unit. In REMOTE
mode, the control system logic issues the
trigger signal to the 9060 unit directly.
In either case, the kV setpoint is displayed on
the kV display, the actual current draw on the
µA display, and the high voltage light illumi-
nates. Under the µA display is a bar graph
meter that illuminates according to the actual
current draw shown in Figure 19.
Figure 19: µA Bar Graph Meter Display
The green and yellow regions of the bar graphs
meter indicate output current is in the optimum
range for maximum transfer efficiency. The red
region of the bar graph indicates high output
current causing decreased transfer efficiency.
If high output, check maintenance of applicator
and external equipment of the power supply .
Measuring "High Voltage On"
Time
The 9060 High Voltage Controller records the
amount of time the high voltage is triggered on
up to 99,999 hours. This value is display on the
kV and µA displays of the unit. There are two
registers that retain this information, one that
may be reset, the other that is permanently
retained in memory. The number of hours the
unit's high voltage has been on may be dis-
played by depressing at the same time the
preset 1 and reset buttons (See Figure 20).
The display will show hours of use for 3 sec-

onds. This is the resettable register.
To reset this register, press the reset button
while the hours are displayed.
To view the non-resettable register, press the
preset 2 and reset buttons at the same time.
This display will show the hours for 3 seconds.

Local/Remote Mode (HV Control)
Button
The 9060 Controller is designed for both
LOCAL and REMOTE use. Although present
on the front panel, the Local/Remote mode
button has no functionality.
mode selection is controlled by the remote I/O
local/remote signal line. The LOCAL and
REMOTE mode (triangle) indicators on the left
and right side of the mode button are shown in
Figure 21. The indicator corresponding to the
unit's current operating mode should be lit while
the unit is on.

If the unit is in remote mode with no ex-
ternal signals connected, the unit is not
functioning properly. Check remote termi-
nal block for an input signal and if none
exists, send the control unit in for repair.
