controller here must be operated in the speed control operating mode, i.e. the output speed of the fans /
compressors is directly proportional to the output voltage from the pack controller.
4. Relay output for power supply bridging
A. For fan speed control
The relay output for fan stage 2 (SIOX 1 terminals 28/25) is used for bypassing the FC / speed controller for the
speed-controlled fans. If the configurable temperature
t
G
-Max
. (menu 3-2-2-1) is exceeded, the enable of the
speed controller is withdrawn (SIOX 1 terminals 15/18, fan output 1 switches off) and the fan output 2 (SIOX 1
terminals 25/28, power supply bridging) is set instead.
B. For fan combined control
The relay output n+1 of the fan stages is used for bypassing the FC / speed controller for fan combined control.
If the configurable temperature
t
G
-Max
. (menu 3-2-2-1)) is exceeded, the enable of the speed controller is
withdrawn (SIOX terminals 15/18, fan output 1 switches off) and the power supply bridging is set instead.
Example: Number of fans n = 3 (combined control - stages)
Number (n) of the digital outputs for fans (L) = 3: Outputs for fan 1 … 3
Relay output for power supply bridging (n+1 = 4): Output fan 4
It must be strictly ensured that the power supply bridging is also realised in the switch cabinet or that
the power supply bridging function is deactivated by setting the parameter

. to "—", otherwise
no more fan capacity is available in the case of too high t
G
(t

> t

-Max.).!
