3.2.4 Scotty 5000 with Telemecanique PLC Control
The Scotty 5000 incorporates two Telemecanique TSX07 Programmable Logic Controllers. Each controller
has a series of LEDs indicating the on/off status of its inputs and outputs. Separate LEDs also verify
communication between controllers. Check Electrical Sheets 8 and 8A for a listing of the devices that are
attached to the controller and to which location (input/output), the device is attached.
When a device is active, the green LED is lit. The yellow com LED should always be lit. The second smaller
PLC will have a blinking red LED in the error position which is normal. The larger primary PLC error lamp
should not be lit.
