When the protective door is opened, the drive must be brought to a
safe standstill and switched off after a safely monitored timer has run
down.
The protective door is opened every 10 minutes in two-shift operation.
The working period is Monday to Friday.
The actuations are calculated to be 6 x 1/h *16 h/d *260d = 24960 per
year.
