ICD_Transporter

Transporter

The transporter is the mechanical part of the AT that is involved in the relocation procedure and hosts the anchoring system.
The control is deployed on the Auxiliary LCU.
The devices are controlled by the Siemens PLC, connected to a RS232 Serial Port via Connector W42.

There will be 10 relative simple on-off drives connected to a manual control panel, for the following functions:

telescope engage/disengage
transporter engage/disengage
telescope up and down
transporter wheels up and down
transporter direction
transporter forwards and backwards
ROS up and down
enclosure open and close
ROS lock and unlock

The complete control of the transporter drives for the whole relocation sequence is under the contractor's responsibility, but status information is provided to the ESO control system via signals connected to the LCUs Digital I/O board.
