Circuitry Protection Devices
To protect the control circuitry from accidental shorts, a low current fuse
(appropriate for the maximum current draw) should be connected in series
between the battery and KSI. Additionally, a high current fuse should be wired
in series with the main contactor to protect the motor, controller, and batteries
from accidental shorts in the power system. The appropriate fuse for each
application should be selected with the help of a reputable fuse manufacturer or
dealer. The standard wiring diagram, Figure 3, shows the recommended location
for each fuse.
Mode Select Switch Operation
The two mode select switches (Mode Select 1 and Mode Select 2) together define
the four operating modes. The switch combinations are shown in Table 2.

Load Sensor [optional]
The 1243GEN2 provides a load sensor input at Pin 1. The controller can be
programmed to vary the strength of regen braking depending on the load sensor
input. The load sensor, if one is used, should be sized to handle your application’s
maximum expected load without exceeding 5 V.
