Belly Switch

WARNING: Ensure the belly switch is only mapped to a digital input when required.
Activation of this input can cause a drive condition to occur.
The belly switch is normally connected to the end of the tiller arm on class 3 vehicles. When
activated it forces a drive condition in forward at a user specified throttle value and maximum
speed for a specified time.
To configure belly:
Ensure the belly switch is mapped to a digital input.
Specify the maximum belly speed at 290C
Specify a belly throttle at 290C
torque mode or speed demand in speed mode.
Specify a belly time out at 290C
has expired.

Drivability select switches

WARNING: Ensure the driveability switches are only mapped to digital inputs when
required. Activation of these inputs can cause driving parameters to change.
There are two drivability select switches (2126
To enable either of these they must be mapped to digital inputs. When they are active, the
corresponding drivability profiles (2921
See Driveability profiles (page 6-26) for more information.

Economy

The economy input is an analogue input which can be used to increase vehicle efficiency and
extend battery life. It is normally controlled using a potentiometer mounted on the vehicle's
dashboard. The economy voltage (2222
Efficiency is improved by reducing the acceleration rate or the maximum torque.
Configure the economy input at object 2912
Economy function: select acceleration or torque.
Economy voltage input: These settings are similar to those for the throttle
(see page 6-20).
The economy value calculated from the voltage can be read at 2622

Pump configuration

The controller can use a mixture of switch and analogue voltages as the pump input. In addition,
the power steer function can be used as an extra input to the pump if the pump motor is required
to supply pump and power steering.
NOTE: Pump motors always run in speed mode. Ensure the motor slave is also configured for
speed mode in 6060
