4.2.2 Terminals of the PS 830
4.2.3 Place and exchange of solenoid fuse
The fuse of the solenoid valve SVD.L is located
on the bottom side of the controller. If the
solenoid valve doesn’t work, should you check
the fuse.
4.2.4 Voltage disconnection
The control unit PS 840 switches off the line volt-
age of the target device via the clamps 1,2 and
3,4. The switching power is 250V / 5A.
The load switched through the terminals 1, 2
and 3, 4 must not exceed the maximum cur-
rent limit (5 A) at any time!
For example, if switch mode power supplies are
used, the starting current is many times higher
than the specified nominal rated current con-
sumption. In this case a start-up current limita-
tion (e.g.an NTC) shall be installed to avoid inad-
missibly high currents.
