Unmodified Orac question

[asto]

Asto,
Have you had a look at the interlock on the key/stop button I understand you turn the key to the right press button and it will not lock down, will display man opp but will not move axis, press and hold for 3-4 seconds to energize the 2 relays before the axis will move.

Hi Phillo5!
Do you know where these relays are located and of what kind they are.Latching relays/normally open maybe? Energized by 5-volt pulses?
Cause in the keyboard matrix there is one 5-volt line.
