Commissioning

Measurements
The ASD supply voltage on terminals 1 and 2 must be checked (check also terminals 3 and 4 in the case of a redundant sup-
ply). The voltage must be between 17.6 and 27.6 V for a correctly set FACP voltage supply (not emergency current operation).
The value depends on the line length. Once commissioning is completed, the measured voltage value is to be entered in the
commissioning protocol (see Sec. 7.8).
With the conductor cross-section determined and installed as described in Sec. 4.8.2, this voltage range must always be avail-
able at the end of the electrical installation – i.e. at the ASD 532 – to ensure that the ASD 532 is able to operate fault-free (see
also Sec. 4.8.2).
Notice
If the measured value is outside the specified range, the ASD 532 may malfunction or even become damaged
(over 30 VDC).
Voltage values that are too low can be caused by insufficiently dimensioned conductor cross-sections or an incor-
rectly set FACP voltage.
