5.3 ELECTRICAL CIRCUITS ____________________________________________________
When troubleshooting the machine using the controller,
always check that Program Active lamps (2 and 3) are on.
These indicate that the controller has power and the program
is active.
Individual circuits can be tested by operating an input switch,
checking for the required input signal, and looking for a
corresponding output. Keep in mind that not all switches are
located on the instrument panel. The traction pedal, reel lift
limit, and brakes are controlled by small reed switches
mounted on the frame of the mower.
If an input lamp does not light an inactive condition is
indicated. This could be caused by a fuse, faulty switch, or
poor connection.
The electrical connections to the solenoids on the hydraulic
valves are also equipped with small indicator lamps. When lit
these lamps indicate that the output signal has reached the
connection. If lamps do not come on, check wires to and from
connector.
NOTICE
The controller requires a minimum of six volts to operate.
