Connecting Receiver to Transmitter Sensor
For ATEX versions of the LDS 6 the receiver sensor are pre-
mounted with special ATEX electronics and surge protection. The
green phoenix contact mounted on the sensor card is already
connected with a red wire for + and a black wire for –. Two addi-
tional wires should be connected to the phoenix connector.
These wires come from the loop cable.
1. Connect the green wire next to the red wire on the phoenix
contact.
2. Connect the brown wire next to the black wire on the phoenix
contact.
3. Connect the sensor housings, on both the transmitter and the
receiver side, to earth using the premounted 2 meter earth
cable (yellow-green).
