Connecting Cables to the Terminal Strip
To control one device through another, you use the multi-pin connector. To
use remote control, you have to connect cables to the terminal strip (both
included with delivery). The single ports are used to exchange control sig-
nals.
Prerequisite
The device has been turned off.
The power plug has been pulled.
Tools
Depressor tool
Electronic defect
Connecting cables to the multi-pin connector of a switched on device
causes a short circuit.
Turn off the device before connecting cables.
Pull the power plug.
Electronic defect
Electrostatic discharge can destroy the electronics.
Wear a protective bracelet against electrostatic discharge and ground.
Process
1. Place the terminal strip
3
on a suitable sur-
face.
2. Push the depressor tool
1
into the opening
on the upper side.
3. Continue pushing the depressor tool down
and lead the cable
2
into the front end of
the terminal strip.
4. Remove the depressor tool.
5. Check whether the cables are tightly
attached.
6. Plug the terminal strip onto the multi-pin
connector.
Next steps
Finish the installation and perform the initial startup.
Error IN
TTL input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short-circuit to ground) from an
external device, an error message appears and the
device stops.
Error GND
Reference point of the voltage at the signal inputs.
+24V
Event-controlled switching of 24 V
against GND
Protection: 24 V – 200 mA
+5V
Provides a voltage of 5 V with respect to GND. This
makes it possible to supply a consumer that is switched
by an EVENT.
Protection: 5 V – 50 mA
GND
Reference point of the voltage at the signal inputs.
