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.
Main conveyor anomalies will show as XX-00 |

| Possible Causes | Checks to Perform |
| Centering device mechanically obstructed | Determine if device is extended or retracted. If extended - turn off main power and see if the device retracts. When retracted - repeatedly press the small button on the solenoid valve and verify the centering device extends and retracts without hesitation. If device struggles to extend because conveyor belt is blocking it - shutdown controlling computer and power cycle the conveyor. With computer still off, push the green start button then use manual rotation knob to carefully align the holes in the conveyor belt with the fingers of the centering device. Once aligned, press the small button on the solenoid valve to verify the centering device fully extends and retracts without hesitation. If device hesitates or fails to move, check if articulating arm is pinched too tight by the mount points. |
| Articulating arm pinched too tight by mount points | If device hesitates or fails to move without manual assistance - apply lubrication to the white neoprene spacers above the track. It may also be necessary to slightly reduce pressure on these spacers via the following instructions: 1) Unlock and loosen the 2x horizontal positioning bolts (above the track) 2) Crack loose the 2x forward facing mount bolts (front of track, behind guard) 3) Use screwdriver to gently pry away the aluminum brackets (a tiny amount) Once the above steps have been completed, gently snug and lock the horizontal positioning bolts (above the track) and tighten the forward facing mount bolts (in front of the track). Once secured, use solenoid test button to verify the centering device fully extends and retracts with ease. |
| Proximity sensor has become damaged or defective | If device moves freely - gently press a piece of metal (screw driver tip, car key, coin, etc) against the sensor face (pointed towards the floor) and verify the LED on the sensor lights up. If LED does not light up when direct contact is made, replace sensor and test. |
| Proximity sensor or standoff bolt out of adjustment | If sensor is functioning correctly, press and hold the small button on the solenoid valve to extend the device. Verify the standoff bolt is in the correct position to trip the sensor. If sensor does not trip when device is forward, adjust the sensor position up/down or standoff bolt up/down as necessary keeping a 1mm to 2mm clearance between the bolt head and sensor. |
| Proximity sensor signal not reaching logic controller | Check whether an input on the PLC lights up in conjunction with the LED on the proximity sensor. Two people are needed to perform this check - one to trip the sensor, and one to watch the inputs on the PLC. If a PLC input does not flicker in conjunction with the sensor - check for +24v DC at PLC channel when sensor is tripped. If voltage is not present but LED on proximity sensor lights up - replace sensor and test. If voltage is present - contact Metalprogetti Support department for further assistance. |
| Pneumatic component compromised or other fault | Contact Metalprogetti Support department for further assistance. |
