IWK-1 feedback cable

Note:

The feedback cable must be run from the lift control valve directly

to the NTA‐2 power supply unit without any intermediate terminals. Any
discontinuity in the feedback cable (break, kink, etc.) can endanger
trouble-free operation.

It is essential that connection 2 is ground-bonded to terminal 12,
otherwise the zero point of the sensor will not be stable.

If you cut the cable to length and terminate it yourself, be sure to wire it
correctly in accordance with the following diagram:
