8MAINTENANCE
The dispenser is designed and built to be relatively maintenance free. To assure
trouble free operation, the following recommendations should be followed:
1. Make certain air supply is clean and dry
2. Avoid turning barrels upside down or laying barrel so that material may
run through air line to internal components
3. Avoid connecting the unit to excessive moisture or solvent saturation.
4. Avoid connecting air supply exceeding 100 psi (6.9 bar) for the DX-350
and 15 psi (1.03 bar) for the DX-355
5. Use only Amyl Alcohol to clean outside surface of the main housing.
6. Use only soft cloth to clean the LCD

11 I/O Configuration and End of Cycle Switch
During a dispense 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 dispense cycle, pin 3 will be grounded. Please make sure the
external device (your machine that controls the dispenser/controller) has the
same ground as the DX-350/355 controller.
Pin 7, 8, and 9 = Available
