If any fault is detected while the fan is running, the fan output is switched off, the relevant fan stage in
the system configuration is deactivated and an alarm is signalled. The fan fault cannot then be
acknowledged until the fan is enabled again in the system configuration.
In the case of speed control, no deactivation of the outputs is performed. In the case of parallel
combined control, no shutdown of fan stage 1 and no disable in the system configuration are
performed.

Setting = NO
An alarm is signalled if any fault is detected while the fan is running. The alarm can be acknowledged:
if the "motor protection" input of the relevant fan is carrying voltage again
after a power failure
4.8.11 Monitoring of the fan speed controller
In the case of types of control with an involved
frequency converter, this is monitored at the
speed controller /
following digital inputs.
Digital input 15 (terminals 78/79) - for "speed controller" type of control
The function of the input is permanently assigned.

4.8.12 External alarm monitoring
An external alarm can be forwarded to the controller via the digital input 15 (terminals 78/79). If there is no
voltage at the input, the message is forwarded after a configurable time delay according to the preselected
priority. The input has no influence on the control functions of the controllers. In the case of operation of the
controller where the HP control is configured as step-by-step switch or combined control -parallel / combined
control -stages, this input is freely available to forward user-defined messages.
The message text for the external alarm (e.g. "Machine room open" can be input (menu 3-5 Alarm Message).
The default text after first start is "External alarm".
