Rotograph EVO (Rev. 1) 8-14
8.2.3.2. E360 and E361: X-ray button pressed during power on
This message is displayed if, during the power on procedure, the X-ray
button, local (E360) or remote (E361) have been sensed as pressed.
Release the button if it was pressed: the error condition is reset powering
off the unit and on again.
If the error is still present, check the continuity of cables of the interested
button. For the local one, S8, it is connected to X18 of the keyboard and
it is transferred to the main CPU using the CANBus cable.
• Check that the cable X18-X18 to the main CPU is well inserted and
its continuity.
• From the main CPU, the signal is routed to the Generator board
(A10), using the CANBus cable X20-X20; check also that this cable is
well inserted and its continuity. Replace it if damaged.
• If the error is still present, check the correct insertion of the flat cable
between the Generator CPU board (A9) to the Generator board (A10).
The cable is labelled X53-X53; replace it if damaged.
WARNING:
On the Generator board (A10) there are dangerous high voltage,
230 VAC and 400 VDC.
Before accessing the Generator CPU and power board (A9 and A10),
it is mandatory to switch off the mains and wait up to 2 minutes in
order to allow the discharge of the capacitor .
