Sheet 1

The first sheet of this drawing shows six connectors that connect to the interlock panel. The first connector, J201, contains the AC power that energizes the observatory E-Stop. If the E-Stop is asserted, the AC will go away and the ADC motor power will be interrupted. The manual paddle can be plugged into the interlock connector or a extension cable can be plugged in that will enable the user to plug the paddle in at the instrument via J607. J401, contains the AC power input for the interlocks. This power comes from channel 3 of the Pulizzi controller. J402 brings the +24V supply into the interlock panel. J403 brings the stage motor drive into the interlock panel. J404 takes the motor drive from the interlock panel and sends it to the stage.

Sheet 2

This sheet shows the two connector that pass I/O signals to and from the interlock panel. The first connector, J405, contains signals running from the interlock panel to the Galil IOM-1964 and the Net/Hardware Err signal running back to the interlock panel.
