Z 1500/2000 DA

3.4.1 Description
The Z 1500/2000 DA is a variant with double acting tilt cylinders and double acting lift cylinders. It is equipped
with a quick opening valve that increases the opening speed of the platform. It has no auto tilt functionality.
Sensors used
Angle sensor located on the platform used for the safety requirement for two hand operation when opening
and closing against the boxy body. The sensor is inactive when the platform angle is within 45 degrees from
vertical and within this range the two hand control is required. If the platform is closer to horizontal, the sensor
is active and the requirement is removed. This sensor is connected to Di3 on ZePRO1.
Pressure sensor located on the positive hydraulic feed to the tilt cylinder used to activate the open platform
alarm. The sensor is active when the pressure drops below 60 bar which enables the Pa+ and Pa- pins on cabin
switch section of the control card. This sensor is connected to Di4 on the ZePRO1
