9. MAINTENANCE
The controller is designed and built to be relatively maintenance free. To assure
trouble free operation, please follow below steps:
1. Make certain air supply is clean and dry.
2. Avoid connecting the unit to excessive moisture or solvent saturation
3. Avoid connecting air supply exceeding 100 psi (6.9 bars)
4. Use only Amyl Alcohol to clean outside surface of the main housing
5. Use only soft cloth to clean the display screen

11. I/O CONFIGURATION AND END OF CYCLE FEEDBACK
During a spray cycle, an open collector circuit closes and remains closed while the
valve is dispensing. Pin 3 and 4 can be as feedback signal to synchronize with other
devices. Power from an external source is allowed to pass through the circuit to
operate a 5 to 24 VDC load. Power consumption must not exceed 250 mA. The
load could be a relay, solenoid, counter, LED, or any device that will operate within
a 5 to 24 VDC range and a maximum of 250 mA.
Note: During the spray cycle, pin 3 will be grounded. Please make sure the
external device (your machine that controls the controller) has the same ground
as the controller.
Pin 7, 8, and 9 = Available
Chassis Ground
