Operation
The PD301 may be used in conjunction with MoT Automated Test Lanes (ATLs). The
operation of the PD301 for MoT testing must be carried out with reference to, and in
accordance with the MoT Tester’s Manual. (copy available from VOSA on request) During
testing, it is necessary to apply the parking brake so that underside inspection can be
safely carried out when using the Play Detector.
On every power-up, the play detector will perform an auto-centre. The plate will first move
right and then left until it comes to rest in the centre position. It will only return back to this
position after each button press in “Continuous Mode” or when the unit is re-started.
To preserve energy and reduce pump / motor wear, the software will de-activate the motor
approximately 2 seconds after each operation.
Note: Ensure the plate is free to move and there is no weight on the plate during the
auto-centre procedure. The plate must be at the centre point before testing a
vehicle.
3.1 The Pedestal
The control pedestal houses the hydraulics and main control system for the Play Detector.
From the pedestal, the operator can switch between Torch or Pedestal mode, and Manual or
Continuous mode. Also there are individual control buttons to manoeuvre the moving plate in
any of four individual directions and an Emergency Stop button that stops the plate
immediately.
