Forced Cooling Fan Malfunction

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Ensure to wait at least five minutes after disconnecting the voltage at all poles before opening the device, as there can be electric discharge in the cubicle. Failure to follow these instructions will result in death or serious injury.

WARNING
HAZARD OF INAPPROPRIATE OPERATION Keep out of the device’s danger zone. When working on the device, switch off the line voltage and ensure that it cannot be switched back on. Wait until the device comes to a stop. After working on the device, remove any tools or other objects from the device. Failure to follow these instructions can result in death, serious injury, or equipment damage.

CAUTION
HAZARD OF INCORRECT MAINTENANCE Ensure no repairs are performed on the forced cooling fans. For repair or replacement of the forced cooling fans, contact Schneider Electric. Failure to follow these instructions can result in injury or equipment damage.

NOTICE
HAZARD OF INADEQUATE MAINTENANCE If the forced cooling fan is not operated for a long period in installed condition in a dry environment, start and operate at full speed for at least one hour every four months. If the forced cooling fan is not operated for a long period in installed condition in a damp environment (for example outdoors), start and operate at full speed for at least two hours once a month. Doing the above will move the bearings and allow any condensate that may have ingresses to evaporate. Failure to follow these instructions can result in equipment damage.

Failure to follow these instructions can result in equipment damage.

Malfunction/Fault	Possible cause	Possible remedy
Impeller not running smoothly	Imbalance in rotating part	Clean the device and replace it if imbalance persists after cleaning. Make sure not to remove weight clips during cleaning.
Motor not turning	Mechanical blockage	Switch off, isolate from supply, and remove mechanical blockage.
	Line voltage faulty	Check line voltage, restore power supply, and apply control signal.
	Faulty connection	Isolate from supply, correct connection. Refer to Connection Diagram.
Motor/electronics over temperature	Deficient cooling	Improve cooling. Let the device cool down. To reset the error message, switch off the line voltage for at least 25 s and then switch it on again.
	Thermal overload protector activated	Allow motor to cool off, locate and rectify the cause of the error, and release restart lockout if necessary
	Ambient temperature too high	Reduce the ambient temperature. Reset by reducing control input to 0.
	Impermissible point of operation	Correct the operating point. Let the device cool down.

NOTE: For any other malfunctions, contact Schneider Electric.
