6.1.3 Arrangement module replacement
i
Information:
Arrangement module part no.: 5009301
The arrangement module is the central network part (12 V) for all other
electronic components and the 12 V fan.
Check:
When the green LED 42 on the front side of the plate is lit or blinking, the
arrangement module is operating correctly. (module self-checking)
When the red LED 41 is lit, the arrangement module is defect and must be
replaced. (module self-checking)
LED 41 and 42 see 6.1.5 Positions of the LEDs on the Controls.
Safety:
When working on the operation module, make sure that the main power
supply is disconnected (an all-pole isolation switch with a minimum contact
opening of 3mm must be located close to the unit- on site) and ensured
against switching on again.
Attention: When the unit is with power, the arrangement module carries live
voltage.
This work should only be performed by a CONVOTHERM trained electrician.
