6 10V DC power supply (I
max
50mA)
Note
Terminal block
The terminal block is led out with spring-loaded terminals. A cable cross-section of 0.08 up to
1.5 mm
2
can be connected to the terminals. A cable cross-section of 1.5 mm
2
is recommended.
Note
Relay output (K1)
An external fault message can be output via the isolated contact of the integrated relay.
During operation, the relay picks up, i.e. connections "11" and "14" are jumpered. If a fault
occurs, the relay drops out (contact load, max. 250V AC 2A).
Note
Factory-inserted jumper between 10V and E1
When delivered, a jumper is inserted between the "10 V" power supply and analog input "E1."
100 % of the speed is achieved during operation in this way.
After the line voltage has been switched on and after a run up time of approx. 20 seconds, the
fan is operated at a constant 100% speed (rated speed).
Note
Speed control via setting signal
Adjust the cooling depending on the duty cycle and the utilization level of the 1PH8 motor.
Remove the jumper inserted in the factory between "10 V" and "E1". The fan speed can be set in
the range 50 …100% using a setpoint signal (0…10V).
