• Each remote controlled lock is associated with one operator station

• If an operator station should fail (emergency) it can be switched to another operator station

• If the energy supply should fail an emergency operation (about 1 hour under full load) is still possible

• If the transmission paths should fail, local operation is still possible

• All operating controls which are needed for the procedure of the lock process, are available at every operator station

• Every dangerous area is monitored by a permanently assigned camera / monitor
