What causes fault code CONV-002 (Conveyor E-Stop Active)?

E-stop button pressed — check all stations along conveyor line. Pull-cord switch activated — cable pulled or switch triggered. Safety relay failed or not reset after E-stop event. Wiring fault in E-stop circuit — open connection in series chain. Safety PLC input module fault

How do I fix fault code CONV-002?

Walk the entire conveyor line — check every E-stop station for pressed buttons. Check pull-cord switches — reset if activated, inspect cable tension. Reset safety relay after all E-stops are released. If no visible activation, check E-stop circuit continuity with meter. Verify safety relay output contacts are closing after reset. Check PLC safety input module for faulted channel

Conveyor E-Stop Active

CONV-002

Emergency stop circuit is open. Conveyor drive is disabled. One or more E-stop devices are activated or circuit has a fault.

Probable Causes (ranked)

E-stop button pressed — check all stations along conveyor line
Pull-cord switch activated — cable pulled or switch triggered
Safety relay failed or not reset after E-stop event
Wiring fault in E-stop circuit — open connection in series chain
Safety PLC input module fault

Fix Steps

1 Walk the entire conveyor line — check every E-stop station for pressed buttons
2 Check pull-cord switches — reset if activated, inspect cable tension
3 Reset safety relay after all E-stops are released
4 If no visible activation, check E-stop circuit continuity with meter
5 Verify safety relay output contacts are closing after reset
6 Check PLC safety input module for faulted channel

Field Trick

In a long conveyor line with many E-stops, use a meter at the safety relay input. Start at the relay and work backward, checking circuit continuity at each junction box until you find the open.
