11. Connection of a single CTP/CTA-BR (separate operation)
If a single CTP/CTA-BR is used, connect the device as shown in Fig. 6. The monitoring outputs can be routed to a control
system.
The following applies to devices with RST input: The switch can be reset using 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 15. System status table CTP/CTA-L1/2-BR on page 38), the reset does not work.
WARNING
In the event of a fault, loss of the safety function due to incorrect connection.
To ensure safety, both safety outputs FO1A and FO1B must always be evaluated.
Ì
Important!
The example shows only an excerpt that is relevant for connection of the CTP/CTA system. The
Ì
example illustrated here does not show complete system planning. The user is responsible for safe
integration into the overall system. Detailed application examples can be found at www.euchner.com.
