ELECTRICAL CONNECTIONS
WARNINGS
Before making the electrical connections, make sure that the supply voltage complies with
that specified in the technical data sheet.
 Emitter and Receiver units must be supplied with 24Vdc±20% power.
 The external power supply must comply with the standard EN 60204-1.
The external power supply must comply with EN 60204 (it can bridge short-term
mains failures of up 20ms).
The electrical connections must be made according to the diagrams in this manual. In
particular, do not connect other devices to the connectors of the Emitter and Receiver.
To guarantee reliability of operation, when using a diode jumper supply unit, its output
capacity must be at least 2000µF for each absorbed A.
TEST COMMAND AND RANGE SELECTION
To select the “Low Range” mode, suggested for all installations below 6m, connect pin 2 to
+24Vdc and pin 4 to 0Vdc. In this mode you can give the test command by bringing pin 2 to
0Vdc too. To select the “High Range” mode, for all installations above 6m, connect pin 2 to
0Vdc and pin 4 to +24Vdc.
In this mode you can give the test command by bringing pin 4 to 0Vdc too. Please see table 2.
