Trendsetter VLF - Timeout Moving Balance Weight Actuator (error number 15844)

Timeout Moving Balance Weight Actuator (error number 15844)


Product		Trendsetter VLF
Component		Balance weights

Error		15844 ALE: Timeout moving balance weight actuator

Symptoms		The balance weight cylinder does not move within the time specified by "altim bct".

Cause		The value of the nvs parameter 'altim bct' (balance cylinder timeout) may be low, the balance cylinder extend/retract sensors may not be working properly, or the air/electrical connections may be faulty.

Solution		Move the drum balance cylinder "act bal1 on/off" or "act bal2 on/off" to verify that the sensor sees the cylinder movement. If the system does not sense that the cylinder is moving, check its actual behaviour by opening the door and looking at it (if servicing remotely, ask the operator to check). If the cylinder is moving, the extend/retract sensors are probably faulty. Check and adjust the hall-effect cylinder. If the sensor is not working, mask the sensor AL BES and save it. Replace the sensor at the next site visit. If the cylinder is not moving, or is still too slow, adjust the control valve or increase "altim bct".
