Sensor Jam Clear Commands
These registers are applicable only to a Sensor Jam condition. By default, in ZPA mode, the ERSC will attempt 3 times to automatically clear a sensor jam and if the sensor is still blocked, the ERSC will stop the zone. To reset this condition the Carton must be manually removed after the 3rd attempt and the sensor cleared before the zone will return to normal operation.
These registers allow the PLC to remotely attempt another auto-clear cycle in an attempt to clear the jam condition. Please note that this function requires the PLC to make a transition from 0 to 1 in the register to initiate another auto-clear cycle. Holding the value to 1 will not cause the retry to continue indefinitely. Each attempt requires a new transition from 0 to 1
