General Description
442G MAB Overview The Guardmaster® Multifunctional Access Box is an electromagnetic
interlocking device with guard locking. The system consists of one locking
module and one handle assembly. An escape release is available as an option.
The Access Box functions by extending the locking bolt from the handle
assembly into the lock module. When the locking bolt is fully extended into
the lock module, the locking arm locks the bolt in this position, preventing the
opening of the guard. The version will determine whether it’s spring force or
solenoid force.
For Power to Release versions, the locking arm is kept in the locked position by
spring force and unlocked by solenoid force when the solenoid is switched ON.
For Power to Lock versions, the locking arm is kept in the locked position by
solenoid force and unlocked by spring force when the solenoid is switched
OFF.
Guard lock monitoring can be deactivated with DIP switches (see Change
Device Configuration (using DIP switches) on page 34).
With ACTIVE Guard Lock Monitoring:
In combination with a movable safety guard and the control system, this safety
device can prevent opening of the safety guard while a dangerous machine
movement is performed. The position of the guard locking is monitored
during this process.
Safety outputs (FO1A, FO1B) are enabled only when the locking bolt is sensed
in its extended position in the lock module AND the locking arm is in position
(for example, the guard is closed and the bolt is both extended and locked).
ATTENTION: For use as a guard locking device in accordance with EN ISO
14119, the guard lock monitoring must be ACTIVE.

Chapter 1 General Description
With INACTIVE Guard Lock Monitoring:
In combination with a movable separating safety guard and the control system,
this safety device prevents dangerous machine movements from occurring
while the safety guard is open. A stop command is triggered if the safety guard
is opened during the dangerous machine function. The position of the guard
locking is not considered during this process.
Safety outputs (FO1A, FO1B) are enabled only when the locking bolt is sensed
in its extended position in the lock module (i.e, the guard door is closed and
the bolt is extended). In this mode, the status of the guard locking is not
considered.

* Apply to hardware revision B and higher.
IMPORTANT The safety outputs (FO1A, FO1B) are not enabled until a handle assembly
has been configured (see Handle Configuration on page 15). After
configuration is completed, the lock module will only recognize the unique
code of the configured handle.

Installation and Wiring
General Considerations Installation must be in accordance with the present manual and must be
performed by qualified personnel exclusively. The Access Box guard locking
switch system is intended to be part of the safety-related control system of a
machine. Before installation, a thorough risk assessment must be performed to
determine whether the specifications (see page 53) of this device are suitable
for all foreseeable operational and environmental characteristics of the
application.
Use appropriate screws, bolts, or nuts that are fitted by tools to mount the lock
module and handle assembly to avoid tampering. Do not over-torque the
mounting hardware.
Handle Configuration The unique-coded handle assembly must be assigned to the locking module
before the system is functional.
During configuration of the handle, the safety outputs are switched off.
• Insert bolt tongue in the locking module.
•Apply operating voltage (U
A and UB).
• The State status indicator flashes (5 Hz) as the device performs a self-test
(up to 8 seconds).
• Programming begins when the State status indicator flashes (1 Hz).
After approximately 60 seconds, the State status indicator turns off.
• To complete the configuration, switch off the operating voltage (UB)
for a minimum of 3 seconds or apply 24V to the input RST for a
minimum of 3 seconds.
IMPORTANT The locking module disables the code for the previous handle assembly if
configuration is conducted for a new handle assembly. A disabled handle
assembly can be configured again only after a third handle assembly has
been configured.

Cutout for Escape Release
IMPORTANT Be careful when mounting the lock module cover to avoid pinching the
ribbon cable.
TIP For easier installation, it is recommended that the handle assembly is
mounted to the guard door before the silver handle is attached to the
handle assembly.
IMPORTANT It must be possible to insert the bolt tongue in the locking module. To check,
close the safety guard several times and actuate the guard door handle.
If available, check the function of the escape release. It must be possible to
operate the escape release from the inside without excessive force
(approximately 40N).
ATTENTION: The escape release must ONLY be accessible from inside the
safeguarded area. The installation must not allow access to the escape
release from outside the safeguarded area.

Escape Release The escape release is used to open a locked safety guard from inside the safe-
guarded area without tools.
With release monitoring active (default factory setting), the system enters into
a latching fault when the escape release is actuated. To reset the device, turn the
power off for at least three seconds or apply 24V to the input RST for a
minimum of three seconds.
Note: A latching fault may not occur if the escape release is actuated slowly.

IMPORTANTIMPORTANT The guard door must be in the open position to clear a latching fault.
IMPORTANT The escape release is not a safety function.
The machine manufacturer must select and use a suitable release according
to the risk assessment.
The correct operation must be checked at regular intervals.
