5.1 Basic display
The default setting displays actual airflow, pressure and/or air speed (selection in the SETUP) and alarm (if
activated).

6) Fan running status
One of 2 relays of the SAT3 option indicates if the fan is actually running (actual value > 20% requested value) or
not.
This allows for example to start an electrical heating coil or a compressor only when the fan is actually running
(contact closed). It is an extra safety feature because you have the certainty the fan is actually running (closed
loop principle)
Wiring diagram: see appendix 6.
7) Alarms
The alarm status output can be taken on the potential free contact R1.
The control box CB2 TAC5 F features 8 alarms :

3 Pa INIT ALARM
4 CA, LS, CPs or CPf
ALARM
Enter nominal airflow to determine corresponding pressure CPf or CPs.
Initialisation of the reference pressure busy. After 1 minute the CB will memorize the value
of the calculated (CPf) or measured (CPs) static pressure on the fan once the INIT airflow
is reached.
Display of instant value of airflow and pressure (CPf) or voltage (CPs) while initializing.
The setup is then completed.
Enter nominal pressure/voltage value for Fan1.
The setup is then completed.

Description
Describes a fan function default. Check wiring, connections and 230V supply.
Otherwise the problem can be caused by defective wire, control circuit or
motor. (1)
It signals a fan pressure alarm.
Alarm LED is lit, R2 relay on SAT3 (option) is closed and theLED over the
SAT3 relay is lit. (1)
1) Actual fan airflow < requested airflow: the requested airflow is located at
a pressure level the fan cannot reach. Change the air system, or the airflow
requested, or a use bigger fan.
2) the nominal airflow requested cannot be reached because the lower
boundary of the fan's working range is reached.
3) Pressure too unstable. (1)
This alarm means the requested airflow or pressure cannot be reached and
the fan is already given the maximum or minimum flow. (1)
