Safety functions
The drive interlock remains enabled for 15 minutes and does not accept any valid keys if
more than 5 keys with different invalid codes are inserted and turned in the ignition lock
within 1 minute.
This function avoids ‘finding’ the correct key by chance by trying different keys.
It is only available if the control valve relay is connected in addition with terminal 30.
The drive interlock remains enabled for 15 minutes and does not accept any valid keys if
several invalid keys have been detected without having set the ignition lock to position 0.
Valid keys are accepted only after 15 minutes and after the position 0 of the ignition lock
has been detected. This avoids testing keys without actuating the mechanical ignition lock,
for example by moving the ignition lock to position 1 by force.
Interruptions of the supply line or other control lines do not disable the drive interlock or
delete data (data codes, for example). All important data is saved in a non-volatile memory.
