The rejector does not function.

1. Is the rejector activated? Turn the Rejector Status function on.

2. If you hear a clicking sound, but the rejector does not activate,

the air pressure is not turned on. Turn on air pressure to the

rejector.

3. The rejector Pulse Width function may need adjustment.

Contact IDC Customer Support for assistance.

4. Disconnect the wire at TB1-26 and use a digital voltmeter to

measure the resistance between the wire and TB1-25. The resis-

tance should be 165 ohms (±10%).

5. Turn the FT-50 on and off and then use the Fire Rejector On

Demand function to ﬁre the rejector. LED 2 on the processor

card should ﬂash for each reject pulse.

• If the LED ﬂashes, but the rejector does not ﬁre; replace the

power supply.

• If the LED does not ﬂash, replace the processor card.

Unstable Main Power

Surges, sags, and transients in the AC mains can cause the

inspection system to falsely reject good containers. If this occurs,

try the following procedures.

1. Check the AC power mains powering the inspection unit using

line voltage measuring equipment to detect surges, sags, and

transients.

2. Check the AC power mains neutral and ground lines for

common-mode voltages and currents.
