1) HOUR COUNTER
There are two possible value options for what will appear in the root menu hand set
display.
- RUNNING = Run time when the steering is enabled.
- KEYON = Time counted continously when the logic is supplied.
2) MICRO CHECK
This feature is to support the debugging activity option. It is used to inhibit the
Supervisor microprocessor operation and allow the system to run with just the Main
microprocessor support. This operating mode does not allow the supervisor
controlled safety switch to close. Therefore, traction is disabled.
- NONE = Inhibit supervisor functions.
- PRESENT = Enable diagnostic interaction between Main and Supervisor
microprocessors.
3) ENCODER CONTROL
Not used. This setting will turn the optional encoder control ON.
4) FEEDBACK DEVICE
Not used. The only feedback device expected is the steer angle feedback pot. This
option (and the previous too) was to cater for an application using the FB encoder
as a FB potentiometer replacement. This choice makes it possible to use the
encoder also for the motor control: it could be a valid support to make steering
control easier in a closed loop application (steering position control).
5) LIMIT DEVICE
When this option is set ON the steer angle feedback pot will be adopted instead of
the limit switches. As soon as the feedback pot voltage overcomes either the SET
MIN FB POT or the SET MAX FB POT adjustment, the steer will be disabled.
6) DIRECTION GAUGE
There are two options for trucks equipped with a steer angle direction gauge. This
setting permits the indicated turning direction displayed on the gauge to be
reversed.
7) AUTO INP ACTIVE
Sets the active logic level (or edge) for the automatic centering mode request
(AUTOSEL).
- Level 0 = External automatic request is active High (i.e. the AUTOSEL switch is
open)
- Level 1 = External automatic request is active Low (i.e. the AUTOSEL switch is
closed)
- Level 2 = External automatic request is active on the rising edge of every odd
number (i.e. the first rising edge is for automatic, the second returns to manual, the
third is for automatic, etc.)
- Level 3 = External automatic request is active on the falling edge of every odd
number (i.e. the first falling edge is for automatic, the second is return to manual,
the third is for automatic, etc.)
