ATA
The stainless steel junction box is designed for the parallel connection of up to 4 load cells.
Type No. of load cells Housing size Inputs Output
KEK-4 up to 4 105 x 210 x 40 mm 4x PG9 1x PG9
The junction box type KEK can be connected to the instrumentation with a shielded 6-wire signal cable.
The corner correction is done with resistors and/or potentiometer.
Housing material: Stainless steel
Protection class: IP65
Cable connection: With clamping terminals
Corner correction: By exchangeable resistors
M ECHANICAL I NSTALLATION
Look for a mounting location which is more or less dry and protected from environmental stress.
E LECTRICAL C ONNECTIONS
Figure 1: Dimensions in [mm]
The connection sequence of the load cells should correspond to the corners of the scale, i.e
Corner 1 = Load cell 1, Corner 2 = Load cell 2, etc.
L OAD C ELL C ABLE C ONNECTION
First the cable gland (see (1) in fig.1) must be loosened. Then you have to feed the load cell cable through the
cable gland unless the shrink tube is fully disappeared in the box. The wires have to run below the printed
circuit board and will be pulled back to the top at the upper end of the printed circuit board. Afterwards you can
connect the cables to the clamping terminals as indicated below:
Cable coulour Description Terminal designation
yellow = Cable shield Shield / Schirm
red = Signal – (Output –) red / rot
white = Signal + (Output +) white /weiss
black = Excitation – (Input –) black / schwarz
(if applicable, brown)* = Sense – black / schwarz
green = Excitation + (Input +) green / grün
(if applicable, blue)* = Sense + green / grün
* if load cell is equiped with 6-wire conductor cable
