ZS MK2 with digital auto tilt

3.2.1 Description
A ZS MK2 variant with double acting tilt cylinders, single acting lift cylinders and digital auto tilt functionality.
Sensor inputs in use:
S1 - The S1 sensor input is bridged to the S1+ sensor power output.
S2 - Liquid-based angle sensor located on the platform used to control the auto tilt functionality. The sensor
is activated when the platform is tilted down from horisontal and stays active untill it is tilted back up to hor-
isontal. As long as the sensor is active, the tail lift will automatically tilt the platform up when the Up-button is
pressed.
S3 - The S3 sensor input is bridged to the S3+ sensor power output.
S4 - Pressure sensor located on the positive hydraulic feed to the left lift cylinder used to activate the open
platfom alarm. The sensor is active when the pressure in the cylinder drops below 60 bar which enables the
Pa+ and Pa- pins on the control card.
S5 - Pressure sensor located on the positive hydraulic feed to the lift cylinder used to control the auto tilt
functionality. Once the tail lift has reached ground level, the pressure in the cylinder drops below 2,5 bar
which activates the sensor which stays active until the pressure exceeds 2,5 bar again. As long as the sensor
is active, the tail lift will automatically tilt the platform down when the Down-button is pressed.
