First determine which device triggered the anomaly by examining the anomaly message on the application's computer console (within the Metalprogetti B2K/BAM/MAP 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 Order Assembly Systems running MAP or 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 |
| Insufficient or missing air pressure | Examine gauge on air regulator and determine if current pressure (black needle) is above the minimum required (green needle). If not, verify sufficient air pressure is available and the air purge valve (red knob) is in working (SUP) position. |
| Air pressure at regulator set too low | If black needle is near or lower than the green needle, try increasing pressure by pulling up on the top knob and rotating counter-clockwise. If black needle does not raise, there is insufficient pressure to regulator and building supply needs to be checked (see above). |
| Minimum required pressure set too high | Verify green needle is set at 0.4MPA. To adjust, rotate and remove clear plastic cover - then manipulate small brass set screw up/down as necessary. |
| Air pressure sensor has become damaged or defective | If black needle is sufficiently above green needle (0.1MPA or more) and anomaly persist - replace gauge and test. |
| Air pressure 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. |
