Errors with no error codes
No indication in the display window (machine
not responding or operates apart from this).
If the power is on, be very careful when
working on the machine.
Verify that:
• the machine receives power.
• the machine has not been emergency stop-
ped.
• the red LEDs on the programme unit card
and the I/O card light steadily. (Verify through
measurement that X:1 - 2 at A11 is 16 V. If
not, troubleshoot the voltage supply circuit.)
• verify that the green LEDs on the programme
unit card and the I/O card blink quickly.
• verify the fuses F11 and F12 (T 1.25 A) in the
rear control unit. Replace burnt-out fuses.

box. Refer to the manual ”Instructions for Clarus
Communication Tests”.
