Connecting the LRGT 1.-.. conductivity transmitter
Please use a shielded, multi-core TC-ER control cable with minimum wire size AWG18, e.g.,
OELFLEX CONTROL TM CY 5G1, to connect the equipment. Max. length
328 ft (100 m).
Connect the terminal strip as shown in the wiring diagram.

Connect the shield as shown in the wiring diagram.
Route the connecting cable between items of equipment separately from power lines.
In the plant:
Electrically connecting the conductivity electrode/transmitter
Connecting the LRG 16-4 conductivity electrode
Please use a shielded, multi-core TC-ER control cable with minimum wire size AWG18, e.g.,
OELFLEX CONTROL TM CY 5G1, to connect the equipment.
Connect the terminal strip as shown in the wiring diagram.

Connect the shield to the central grounding point (CGP) in the control cabinet.
The cable length between the conductivity electrode/resistance thermometer and conduc-
tivity controller is max. 98 ft (30 m), or max. 32 ft (10 m) with a conductivity of 0.5 - 5 ppm
(1- 10 µS/cm).
Route the connecting cable between items of equipment separately from power lines.
The LRG 16-9 conductivity electrode is equipped with an M12 A-coded, 5-pole sensor connector,
see
Fig. 3
for assignment. A pre-wired control cable (with connector and socket) is available in
various lengths as an accessory for connecting the equipment.
This control cable is not UV-resistant and must be protected with a UV-resistant plastic
tube or cable duct if installation is outdoors.
For connection to the LRR 1-50 conductivity controller, please remove the connector and wire the
terminal strip as shown in the wiring diagram.

Connect the shield to the central grounding point (CGP) in the control cabinet.
If you are not using the pre-wired control cable, lay a five-core TC-ER control cable with minimum
wire size AWG18, e.g., OELFLEX CONTROL TM CY 5G1, as the connecting cable. In addition, con-
nect a socket, e.g., Binder series 713 99-0436-58-05,
to the control cable at the electrode end.
The cable length between the conductivity electrode and controller is max. 98 ft (30 m), or
max. 32 ft (10 m) with a conductivity of 0.5 - 5 ppm (1 - 10 µS/cm).
Route the connecting cable between items of equipment separately from power lines.
Connecting the LRG 16-9 conductivity electrode
Attention
■
Please bring the equipment into service as described in the LRG 16-4,
LRG 16-9 and LRGT 1.-.. Installation & Operating Manuals.
■
Route the connecting cable between items of equipment separately from power
lines.
■
Check the connection of the shield to the central grounding point (CGP) in the
control cabinet.
■
The conductivity transmitter must be connected to its own dedicated supply
voltage.
