Section 9 K-Tech Load Weigh System (Pretorque only)
Controllers with pretorque use the K-Tech Load Weigh System. Proper installation and
adjustment of this device is essential to the operation of the control system. Failure to follow
the procedures outlined in this section can result in poor ride quality and improper operation of
the control system.
This section is intended as a supplement to the K-Tech Installation Adjustment manual. Read
all related material before beginning installation of the unit.
Before installing the and adjusting the K-Tech Load Weigh system you must first determine
which system you have. To do this, look at the cover of the electronics box. On it you will see a
label with the model number of the unit.
There are two systems presently in use, the LW3200, and the LW4201. The latter is the latest
system, and incorporates an automatic re-calibration feature, eliminating the need for periodic
re-calibration of the unit. For installation of the LW3200, refer to section 9.1 of this chapter. For
LW4201, refer to section 9.2.

9.1.1

Preparation

Before beginning the installation of the unit, the car should be adjusted and running at contract
speed. The cab should be complete, with all walls, ceiling panels, and flooring installed. If not,
do not install the unit until the cab is complete!
9.1.2

Sensor Mounting

The sensor must be mounted while the car is empty and at the lowest landing. Failure to do so
could cause the sensor to 'unload' at lower floors and lead to erratic operation.
Locate an area of the crosshead about 1/3
of the way from the end. This area should
be clear of brackets or other structural
members.
