10) ZERO SP POT
Is only for a two pots steering application. It is used to capture the zero setting of
the steer handle pot for manual mode steering.
11) SET STEER 0-POS
Is used to set the voltage the steer angle feedback pot wiper will assume at the end
of an automatic centering operation. Adjust this setting by Entering SET STEER 0-
POS. The default value is 2500.0 mV. You may roll the value up and down using
the (5) and (6) keys in 5mV increments until the truck will move straight ahead after
centering.
12) SET MIN FB POT
it is used to adjust the scaling of the counterclockwise 90 degrees rotation of the
MDU for use with the LEDs steer angle indicator and to stop steering when this
value is surpassed and LIMIT DEVICE setting is ON. Adjust this setting with
guidance in manual mode (tacho or stepper motor controlled steering). Turn the
handle-wheel counterclockwise until the maximum 90 degrees angle is obtained.
With the SET MIN FB POT in the ZAPI hand set display, push the ENTER (3)
button. The display changes to the present feedback pot value. Push the OUT (4)
and the ENTER (3) button to save this new reading.
13) SET MAX FB POT
Is used to adjust the scaling of the clockwise 90 degrees rotation of the MDU for
use with the LEDs steer angle indicator and to stop steering when this value is
surpassed and LIMIT DEVICE setting is ON. Adjust this setting with guidance in
manual mode (tacho or stepper motor controlled steering). Turn the handle-wheel
clockwise until the maximum 90 degrees angle is optained. With the SET MAX FB
POT in the ZAPI hand set display, push the ENTER (3) button. The display changes
to the present feedback pot value. Push the OUT (4) and the ENTER (3) button to
save this new reading.
14) AUX VOLTAGE #1
Is for the stepper motor application only. This voltage is auto acquired the first time
the EPS-AC is switched on and corresponds to the voltage level in the D line (CNB-
3) when the stepper motor is standing. Typical 2.5V.
15) AUX VOLTAGE #2
Is for the stepper motor application only. This voltage is auto acquired the first time
the EPS-AC is switched on and corresponds to the voltage level in the Q line (CNB-
9) when the stepper motor is standing. Typical 2.5V.
