9.5.1 EMERGENCY STOP CIRCUIT
To check the emergency stop circuit, check the CPU IN /OUT screen in Test Mode and
SELECT THE LINE "Emergency Stop" : if the red knob is in the rest position (circuit
closed, movement possible), the message will read ON. When the red knob is pressed, the
message will change to OFF (circuit open, motors stopped). When the knob is turned
clockwise, the movement system is ready to operate. The message turns back to ON
(movement system ready).
However: the previous check only covers the signal processed by the CPU but the problem
could lie in a circuit which goes directly to the drivers. To check whether this is the case,
select the Movement Test from the MOVEMENT SYSTEM screen while in Test Mode.
Refer to the circuit diagram in following the steps below:
When the Movement Test option is selected, the optocoupler breaks the circuits of the
footrest micro-switches (see right-hand side of illustration).
Under normal conditions, when the button is in the rest position (i.e. not pressed), the
message " rd " will appear in the left-hand window of both drivers. However, if the message
is " ih ", this indicates that the circuit remains open for some reason (e.g. bad connection,
damaged cable, faulty button, etc.). The stop message will appear on the monitor screen,
consisting of an image of the stop knob and an acoustic warning.
