Installation
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.
Start IN
TTL Input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short-circuit to ground)
from an external device, the device starts. If con-
trolled with software, an electronic trigger is send
through the LAN.
Autozero
TTL Input
Low active
Secure switching threshold at least 10 mA
A signal (short-circuit to ground) sets the measur-
ing signal to zero.
+5 V
Provides a voltage of 5 V with respect to GND.
This makes it possible to supply a load that is
switched by an EVENT.
Protection: 5 V–50 mA
GND
Reference point of the voltage at the signal inputs.
+24 V Valve
Event-controlled switching of 24 V
against GND
Protection: 24 V–200 mA
Valve OUT
Output is active until the valve condition has been
eliminated.
GND
Reference point of the voltage at the signal inputs.
