Toro SA41 User Manual

25

The SA41 employs a rear chassis-mounted 25-pin connector, which allows you to add a selection of
optional features to your power system. Note that the software for these functions is already
installed within the SA41 microcontroller.

 The full range of features are:

(a) Remote Keypad:

A low profile keypad with 2-line Liquid Crystal Display, which can

be  located up to 500 metres from your SA41.

Wiring requirements - 6 conductor shielded cable.

(b) DC Current Shunt: Consists of a 200 Amp 75mV current shunt, mounted on an insulated

  base, and a twin flex loom for current sensing.

(c) Controller Outputs: Two external relay or contactor coils can be energised for various AC

or DC switching  applications.

(d) Alarm Inputs:

Two digital inputs that can be programmed to monitor switch contact

status or voltage levels (refer to following circuits for examples)

The Interface Kit SA-SB-01 plugs into the rear of the SA41 and provides a convenient termination
point for the various options outlined above. The screw terminals are numbered from 1 to 14 and
the connections are as follows:
