Graco CycleFlo [11/18] Self test mode

309003 11

Self-Test Mode

CAUTION

During this test, the solenoid valves may be acti-

vated. This will activate a connected pump. To

prevent inadvertent pumping, disconnect the air

supply to the solenoid valves or remove the air lines

to the pump.

TEST MODE (SW1–7)

The CycleFlo has a built-in test program that allows for

dynamic testing of all internal and external compo-

nents.

Once activated, the self-test mode will do the following

continuously until the test mode is de-activated:

D All display digits count from 0–9 in unison. This is

used to determine if any of the displays are faulty.

Replace the display board if segments of the dis-

play fail to activate during the self-test.

D Each of the five front panel buttons activates a

decimal point on the LED displays. Replace the

display board if a button fails to activate a decimal

point.

Position SW1–7 to the ON position to activate the

self-test mode. Position SW1–7 to the OFF position to

de-activate the self-test mode.

REMOTE RUN TEST (SW1–8)

Position SW1–8 (the REMOTE RUN test) to the ON

position to activate the AIR SUPPLY VALVE signal and

cycle the solenoid valves at the CPM rate set by

SW1–1, 2, 3, 4. The Remote Run Test (SW1–8) per-

forms the same function as closing the Remote Run

Switch input, and therefore, is used to test the func-

tionality of the Remote Run Switch input. Follow the

Troubleshooting Guide on page 10 if either fails to

operate.
