Connection
The device is connected as shown in
. The monitoring outputs can be routed to a control system.
The switch can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 s. The RST
input must be connected to 0 V if it is not used.
If there is an internal error (see chapter
5. System status table CTP/CTA-L1/2-BP on page 26
), the reset does not work.
WARNING
