Connecting the data line between the conductivity controller and the URB 55
A pre-wired control cable with socket is supplied for connecting the equipment. For terminal
assignment, see wiring diagrams
Fig. 16
to
Fig. 18
.
■
If you are not using the pre-wired control cable, you must use a shielded, twisted-pair control
cable with minimum wire size AWG23 (0.25 mm
2
), e.g., LIYCY 2 x AWG23 (0.25 mm
2
).
■
Maximum cable length 98 ft (30 m).
■
Wire the terminal strip as shown in wiring diagrams
Fig. 16
to
Fig. 18
.
■
Wire the 9-pole D-Sub connector as shown in
Fig. 15
.
■
Connect the grounding point of the enclosure (URB 55) to the central grounding point in the
control cabinet. Connect the shield just once to the central grounding point in the control
cabinet.
■
Route connecting cables separately from power cables.
Connecting the SPECTORmodul bus system
Using the supplied data cable [16 ft (5 m)], connect the URB 55 to the first controller in the system.
If the system has a second controller, position this immediately next to the first controller and
connect terminals 11 and 12 of the two controllers to one another as follows:
■
Terminal 11 (controller 1) to terminal 11 of controller 2
■
Terminal 12 (controller 1) to terminal 12 of controller 2
