850645-01
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 a minimum conductor size of 0.25 mm
2
, e.g. LIYCY 2 x 0.25 mm
2
.
■
Maximum cable length 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 earthing point of the housing (URB 55) to the central earthing point in the control cabinet.
Connect the shield just once to the central earthing point in the control cabinet.
■
Route connecting cables separately from power cables.
Connecting the SPECTORmodul bus system
Using the supplied data cable (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 of controller 1 to terminal 11 of controller 2
■
Terminal 12 of controller 1 to terminal 12 of controller 2
