Multifunctional Access Box and Guard Locking with Time Delay Safety Relay
Bolt Locking Mechanisms
The access box has two mechanisms for locking the bolt actuator to prevent
locking the guard and restart of the machine while an operator is inside the
safeguarded area.
One of the bolt locking mechanisms automatically extends when the handle is
in the OPEN position. The other mechanism is manually extended (see Figure
1). To pivot out, press the grooved part (only possible with the handle in the
OPEN position and the bolt retracted).

IMPORTANT
With the manual bolt locking mechanism rolled out, the bolt cannot be
extended.
