Fan motor SCC Line 61 - 202

Bus
Only when the green LED is ON (power supply existing and electronic motor control ok), the motor is
functional
The fan motor rotates clockwise - anti clockwise with a 120 second interval.
On floor units with 2 motors the bottom motor carries a jumper for bus recognition. This jumper
(40.01.581) is part of the wiring harness. Caution: These jumper pins carry 120Vac!

It is possible that the motor will reduce speed independently to avoid energy transfer by the rotating fan wheel.
In case the motor develops an internal problem, it will stop and try to restart after 10 seconds. During this time hot
air productions is stopped, steam is still possible. In the service history Service 55 or 56 (bottom motor) is shown.
(ref. to blink code under "Error messages"
Note: In this case there is no Service 34.x error! - Motor doesn't turn, hot air heating is blocked
When changing the fan motor, a new motor shaft gasket must always be used!
Failure of the fan motor can have different reasons, mainly humidity or voltage
related.
Check all possible humidity sources (steam pipe from steam generator to cabi-
net, motor shaft gasket, connection control box to vent pipe, water connections
to nozzles and solenoids etc. )
Check power connections, units 3NAC build before 11_2014: connect motor
power supply to L1, (ref. TI 19 - 2014, MI 01 - 2015)
