REJECT - LOST TACH
Symptom:
The tach signal from the transport was lost.
This is a reject message.
The bill was rejected because the CCC cannot control the transport motor speed without a tach. signal.
Corrective Action:
1. An object is possibly hung-up or jammed in the track.
2. Check for a tach. signal as outlined in Test Procedures in Section 3. Replace the transport if the tach. is bad.
3. Check for intermittent connections in the wiring from the transport to the CCC (P4 - Pin 9).
4. If all of the preceding checks are OK, replace the CCC.
REJECT - VF OPEN
Symptom:
The flipper cell opened too soon.
This is a reject message.
The bill was rejected because the VF cell opened during validation.
The bill is possibly torn, or it may have a hole in it.
An object is possibly hung-up or jammed in the track near the flipper.
If bills are frequently rejected for this message, take the following corrective action:
Corrective Action:
1. Check for tight, binding, or sticky flipper operation.
2. Check for an intermittent open circuit in the wiring to the VF cell from CCC (P4 - pin 7).
3. If the preceding checks do not find the problem, replace the CCC.
If a bill is left in the transport for five seconds, the bill changer will go into
SELF-CLEAR.
