F30 Error in semiconductor test (timeout or
mu
ltifuse)
Turn supply voltage off and on again; if it
occurs again, send the device in
F32* RES operating mode changed
(during oper
ation)
Switch supply voltage off and on again
F33* EDM operating mode changed
(during operation)
Switch supply voltage off and on again

cl
oses or will not open)
Check EDM wiring, turn supply voltage
off and on again
F35* Start/restart button pressed longer than
10 seconds
Check the start button wiring

longer than
3 seconds
Check transmitter test input
F37* EDM configuration error Check EDM wiring, turn supply voltage
off
and on again

Code Cause/significance Activity for removing errors
*) Locking error - a system reset is only achieved by switching the supply voltage off and on.
