12.1 Additional switching output for a step
The controller has only 6 or 12 switching outputs. An additional switching output, however, is required
for a step.
Solution:
The CX plus offers the possibility to use the switching output for the fan as additional switching output
for a step.
Procedure:
Activate
the function “
Use the switching output FAN as step switching output
”
(SETUP/406).
Set the setting to “
YES
” in the SETUP menu 406.
!
CAUTION
When you switch between functions, all active steps must always be switched off one by one first,
before the control may restart. FON steps are not switched off.
Set the step type for the additional switching output (SETUP/100/OUt and SETUP/403).
Set the desired step type for the step output no. 7 resp. 13 in the SETUP menu 100/OUt or 403
(
DEFAULT: “AUTO”).
If the step identification is switched off (SETUP/308 =
NO
), the step size for the step output
no. 7 resp. 13 must be entered manually in the SETUP menu 402.
Function:
If the step type is set to “
AUTO
”, the controller uses the “fan switching output” as 7
th
resp. 13
th
step. If
the controlle
r switches on the switching output, this is signalled with the step symbol “7” resp. “13” on
the display. If the step type is set to “FON”, this step is permanently switched on.
NOTE:
If the function “Use the switching output FAN as step 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).
