4.6 POTENTIOMETERS
PUMP Adjustment (PUMP ADJ) –
Output 10
The PUMP ADJ potentiometer is used to increase or decrease the frequency of Output 10
which affects the pump frequency. The pump frequency is adjustable from 20 –
80
cycles
per minute.
Rotating the potentiometer dial
clockwise
will increase the output frequency.
Rotating the potentiometer dial
counterclockwise
will decrease the output frequency.
HIGH Voltage Adjustment (H.V. ADJ)
The H.V. ADJ potentiometer is used to increase or decrease the output of the High Voltage
Power Supply. The High Voltage Power Supply is adjustable from 0 –
30,000
VDC.
Rotating the potentiometer dial
clockwise
will increase the high voltage output.
Rotating the potentiometer dial
counterclockwise
will decrease the high voltage output.
Measuring Exact Output Voltage
The High Voltage Power Supply output can be determined by measuring the DC Voltage
across TP1 (Test Point 1) and Ground. The DC Voltage will be a reference between 0 and
5.0 VDC. To determine the actual High Voltage Output multiply the Voltage across TP1 and
Ground times 6 kV/volt.
Example:
Voltage across TP1 is measured as 2.2 VDC
(2.2 volts) (6 kV/volt) = 13.2 kV
= 13,200 VDC
DWELL Adjustment (DWELL ADJ)
Factory use only, corresponds with Output 8.
4.7 SYSTEM MODES
PRIME MODE
Terminal Block J9
-
INPUT 1
-
Connection 1 & 2 and/or PCB Mounted Pushbutton
Prime mode
-
will cycle the pump outputs for a period of 60 minutes and should be used during system
installation or the fluid lines to the nozzles need to be filled prior to spraying. The pump cycle during Prime
mode is 120 CPM.
Note: It may require several Prime mode cycles before fluid reaches the nozzle opening, depending on
selected fluid line length, flow rate, and fluid viscosity.
Terminal block J9
-
Input
1 is intended for a
customer
-
installed
normally
-
open momentary pushbutton
(Optional).
Input 1 will only be active if the system is in Standby Mode. This means that the
system cannot be in Lubrication Mode, Burst Mode, Test Mode, or any fault condition.
—The PCB mounted PRIME pushbutton will be fully functional whether or not Block J9, Input 1
is connected.
