The internal solenoid valve fuse must be
adapted to the solenoid valve
4.2.2 Terminals of the PS 830
Terminal Description
1,2 relay contact 1
3,4 relay contact 2
5,6 terminal for solenoid valve
mains, according to model conductor N
7,8 –
or minus by DC
mains, according to model condcutor L1
9,10 +
or plus by DC
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.

4.2.3 电磁阀保险丝的放置和更换
电磁阀SVD.L的保险丝位于控制器的底部。 如
果电磁阀不工作，你应该检查保险丝。
4.2.4 电压断开
控制单元PS840通过夹子1,2和3,4关闭目标设
备的线路电压，开关功率为250V/5A。
通过终端1、2和3、4切换的负载在任何时候都
不得超过最大电流限制(5A)！
例如，如果使用开关模式电源，则启动电流比指
定的额定电流消耗高许多倍。 在这种情况下，
应安装启动电流限制(例如NTC)，以避免不合理
的大电流。
