A
DDITIONAL SWITCHING OUTPUT FOR A STAGE
The controller has only 6 or 12 switching outputs. An additional switching output, however, is required
for a stage.
Solution:
The CX plus offers the possibility to use the switching output for the fan as additional switching output
for a stage.
Procedure:

Activate the function
“
Use the switching output FAN as stage switching output
”
(SETUP/406).
Set the option to
“
YES
” in the SETUP menu 406.
! CAUTION
When it is switch between functions, all active stages must always be switched off one by one first,
before the control may restart. FON stages are not switched off.

Set the stage type for the additional switching output (SETUP/100/OUt and SETUP/403).
Set the desired stage type for the stage output no. 7 resp. 13 in the SETUP menu 100/OUt or 403
(DEFAULT:
“AUTO”).

If the stage recognition is switched off (SETUP/308 = NO ), the stage size for the stage output
no. 7 resp. 13 must be entered manually in the SETUP menu 402.
Function:
If the stage type is set to
“
AUTO
”, the controller uses the “fan switching output” as 7
th resp. 13 th stage.
If the controller switches on the switching output, this is signalled with the stage symbol
“7” resp. “13”
on the display. If the stage type is set to
“FON”, this stage is permanently switched on.
NOTE:
If the function “Use the switching output FAN as stage switching output” (SETUP/406) is
activated, the fan activation by the alarm system is deactivated. If the temperature limit 1 is exceeded,
the status message
“FAN” is no longer displayed. The switching output fan which has been switched
on by the alarm system is immediately switched off. It is now activated by the control (additional
switching output).
F
AN ACTIVATION
The controller shall take over the fan activation depending on the temperature in the switch cabinet.
Solution:
The CX plus is equipped with a temperature sensor (NTC) integrated under the housing. The limit value,
at which the switching output for the fan shall be activated, can be set in the alarm system.
Procedure:

Deactivate the function
“
Use the switching output FAN as stage switching output
”
(SETUP/406).
Set the setting to
“
NO
” in the SETUP menu 406 (DEFAULT).
!
CAUTION
If the current setting is changed, all active stages are switched off and on again. FON stages are not
switched off.
