First determine which device triggered the anomaly by examining the anomaly message on the application's computer console (within the Metalprogetti B2K/BAM application).
For Uniform Conveyor Systems running B2K
The anomaly record will contain both the CONVEYOR number as well as a POINT description which indicates the faulting device (arm, gate, etc).
For Storage Systems running BAM
The device ID is made up of 4 digits - the first 2 indicate the conveyor ID, the second 2 indicate the device ID.
In the following examples, XX represents conveyor ID while the last 2 digits represent the device.
Main conveyor anomalies will always be XX-00,
extraction arm anomalies will always be XX-01 through XX-10 depending on how many arms are installed,
and feedrail anomalies will always be XX-11 as demonstrated below.

| Possible Causes | Checks to Perform |
| Spreading device mechanically obstructed | Verify spreader bars are not prevented from fully closing by jammed hangers. |
| Proximity sensor has become damaged or defective | Verify proximity sensor responds to the presence of metal by placing something metallic on the face of the sensor and observing if the sensor LED lights up. If LED does not light up when metal is touching the face - replace sensor and test. |
| Proximity sensor or actuation bracket out of position | Shut off air pressure by turning the valve on the regulator to the off position - then fully open and extend the spreader bars. Once all the way forward and in the down position, verify the LED on PX18 lights up as the angled bracket comes in contact. If LED does not light up, determine if the sensor or the standoff bracket needs adjustment and adjust as necessary. If LED lights up, proceed with next check. |
| Sensor signal not reaching PLC in main panel | Use the following instructions to determine if sensor signal is reaching the PLC: 1) Turn main power off and open power panel door 2) With door open, turn main power on (see note below) 3) Acquire assistant to actuate sensor on/off repeatedly 4) Observe PLC and look for input LED to flicker in conjunction with sensor If unable to correlate or detect the PLC input pulses, contact Metalprogetti Support department for further assistance. To Turn Main Power ON/OFF with DOOR OPEN - Identify the master on/off switch inside the panel (usually a long square rod protruding from the middle of panel or nearby) and then firmly grasp the manual actuator and rotate (clockwise for ON, counter-clockwise for OFF). If unsure or unable to turn the actuator, escalate to appropriate team members. Observe all standard safety precautions and protocols. |
