Bolt Locking Mechanism
The Access Box has two mechanisms for locking the bolt actuator to prevent
locking the guard and restarting the machine while an operator is inside the
safeguarded area.
ATTENTION: The mechanical lifetime of the emergency release is limited to
20,000 actuations. Then the bolt of the locking module does not allow
further emergency releases. To make this function available again, the whole
locking module has to be exchanged.
