Cable extension
one of the most common faults on a MJK 713
installation is bad or faulty cable connections.
It is recommended to use a MJK connection box if the
sensor cable must be extended.
Ultrasonic sensor
the Shuttle
® ultrasonic sensor are standard de-livered
with 40 ft of cable. the ultrasonic sensor can be deliv-
ered with up to 150 ft of cable on order, or the standard
40 ft cable can be extended to max. 150 ft.
The cable is a special low capacity cable,
so extensions should always be made with
the same type of cable.
the ultrasonic sensor cable has 5 wires with both color
code and number:
Number: Color: Designation:
1 Brown Ultrasonic pulse
2 red
3 orange temperature compensation
4 Yellow
5 Black Shield )*
)* This wire is connected to the cable shield.
the wires are mounted according to the terminal mark-
ings on the connection box PCB and on the MJK 713
respectively.
Cutting the cable
the cable is delivered with the wires stripped as shown
with the black wire (no. 5) soldered to the shield:
when the cable is cut, only 4 wires will appear:
When the cable has been cut, the shield
should be mounted in terminal 5 instead of
the black wire !
when the ultrasonic sensor is mounted and connected
correctly, the MJK 713 can be connected to the power
supply.
