Installation instructions for the electrical installer
EU declaration of conformity
The package leaflet is part of the device's scope of delivery. The documents are available as PDF files
and can be downloaded from the manufacturer's website.
A lockable housing with protection type IP54 is recommended for device installation.
•
Connect the device according to the installation instructions.
•
Ensure that the connected sensor and transmitter corresponds to the intended configuration.
•
Check the functionality of the device with a connected transmitter and sensor for correct functioning.
•
A calibrated sensor simulator and a calibrated digital multimeter may be required to test the device
with a connected transmitter
•
Put the safety circuit into operation and check it for correct functioning.

Notes for operation
In standard operation, the green LED (PWR) lights up continuously.
If a malfunction occurs during operation, then the output signal is usually set to a value outside the "nor-
mal" signal range of 3.6 to 21 mA. The connected SIS should therefore check the loaded signal values
for validity and initiate corresponding measures if they deviate from the normal values.
Make sure that the connected measuring transmitters respond to line faults at the sensors.
After switching off and switching back on, the required voltages are established in the device. Signal
transmission then occurs without any further measures.
