What causes fault code CONV-008 (Sortation Diverter Fault)?

Pneumatic cylinder not actuating — air supply issue. Solenoid valve stuck or failed — check coil and spool. Position confirm sensor not seeing diverter in position. Mechanical obstruction preventing full diverter travel. PLC output not energizing — check output module LED

How do I fix fault code CONV-008?

Check air supply — gauge should read plant spec (typically 80-90 PSI). Manually actuate solenoid valve — use manual override button on valve. Check position confirm sensors — verify they see diverter at both retracted and extended. Inspect diverter mechanism for jammed products or debris. Check PLC output — verify output LED is ON when divert commanded. If valve good but cylinder slow, check flow controls and cylinder seals

Sortation Diverter Fault

CONV-008

Sortation diverter (pop-up wheel, pusher, or shoe sorter) failed to actuate or did not reach position within time limit.

Probable Causes (ranked)

Pneumatic cylinder not actuating — air supply issue
Solenoid valve stuck or failed — check coil and spool
Position confirm sensor not seeing diverter in position
Mechanical obstruction preventing full diverter travel
PLC output not energizing — check output module LED

Fix Steps

1 Check air supply — gauge should read plant spec (typically 80-90 PSI)
2 Manually actuate solenoid valve — use manual override button on valve
3 Check position confirm sensors — verify they see diverter at both retracted and extended
4 Inspect diverter mechanism for jammed products or debris
5 Check PLC output — verify output LED is ON when divert commanded
6 If valve good but cylinder slow, check flow controls and cylinder seals

Field Trick

Hit the manual override on the solenoid valve. If the diverter moves, the problem is electrical (PLC output or solenoid coil). If it doesn't move, it's pneumatic or mechanical.
