Error 69 - Theoretical Maximum Pre-Wet Hz Too High. Based on the specified application
rate setpoints, and the maximum ground speed, the maximum theoretical pre-wet pump
flow required has been calculated to be more than twice the actual pump capacity, which
will lead to serious under-application problems. The actual pump flow setpoint will be
clamped at this value to prevent the controller from becoming unstable, and the pre-wet
pump should be re-calibrated to determine the source of the problem.
Error 70 - Theoretical Maximum Anti-Ice Hz Too High. Based on the specified application
rate setpoints, and the maximum ground speed, the maximum theoretical anti-ice pump
flow required has been calculated to be more than twice the actual pump capacity, which
will lead to serious under-application problems. The actual pump flow setpoint will be
clamped at this value to prevent the controller from becoming unstable, and the anti-ice
pump should be re-calibrated to determine the source of the problem.
19 Joystick Calibration
19.1 Solenoid Nulling
1. Start vehicle and achieve full pump flow.
2. Tap on Joystick symbol.
3. Press “CALIBRATION” button and press a mode button on the
joystick to select a desired mode to adjust.
4. Move the joystick slightly until the hydraulic actuator moves slowly – press “Min” while
the stick is deflected.
5. Move the joystick until the actuator moves at a safe maximum speed – press “Max”.
6. Repeat this for all axis’, directions and modes.
LmtRst – Dump limit warning disappears once acknowledged
Press “CALIBRATION” button again to save all changes.
