The recommended patchcord for use with GuardLink® and ArmorBlock® Guard Safety I/O is the 2 m (6.5 ft) catalog number
889D-F5ACDM-2. Replace the 2 with 0M3 [0M3 (0.98 ft)], 1 [1 m (3.28 ft)], 5 [5 m (16.4 ft)], or 10 [10 m (32.8 ft)] for standard cable lengths.

OSSD Mode Safety Signals
In OSSD mode, safety outputs Safety A and Safety B are OFF (0V) when the switch is in safe state (that is, the switch is unlocked). When the switch is in operational state (that is, closed and locked), safety outputs Safety A and Safety
B are ON (24V) and contain test pulses. The test pulses are used to detect short circuits to 24V, to 0V and cross faults (from Safety A to Safety B). This description of the test pulses is provided for informational purposes; you cannot modify them.
IMPORTANT To prohibit nuisance tripping, mask the OSSD input channels of the safety system with an On to Off delay of at least 1 ms.

When the 440G-MZ safety switch is connected in a GuardLink system, the safety signals are Safety In and Safety Out. These signals are dynamic signals in operational state and two-way communication signals in the safe state.
ATTENTION: For information on a known anomaly, see Knowledgebase Article
Unlocked 440G-MZ switch on GuardLink doesn't respond to lock command on power up
.
Figure 8 on page 21 shows the basic components of a GuardLink system with a
DG safety relay master. The 440G-MZ safety switch, with embedded
GuardLink technology, connects to the link with a passive tap (as shown in
Figure 8 on page 21 ) or a passive power tap (catalog number 440S-PF5D4).

Chapter 4 Wiring and System Integration
Different types and versions of GuardLink enabled and passive taps can be connected in any order and can be mixed on the same link. For more information about the configuration a GuardLink safety system, see publication 440R-UM015 .
Both the Power to Release and Power to Lock versions of the 440G-MZ safety switch can be connected to a GuardLink safety system.

Add Device to a Studio 5000
Project
Information about how to add a 440G-MZ safety switch to a GuardLink system in a Studio 5000® project can be found in the user manual for the GuardLink safety master. See publication 440R-UM009 for information about using the upload method or manual method to add a 440G-MZ safety switch in a
GuardLink circuit controlled by a Guardmaster® DG safety relay.

shows the lock command function. The lock command is a 24V logic signal with a current of less than 2 mA. The function of the logic signal is dependent on the catalog number.

GuardLink Mode
In a GuardLink system, the GuardLink safety master (for example a DG safety relay) issues lock and unlock commands to the 440G-MZ safety switch via the
GuardLink Control, Lock, and Unlock (CLU) signal. This signal is either static or dynamic. When static, this signal is LO when the system is operational and
HI when a demand is placed on the safety system. The signal is dynamic when an unlock or lock command is issued to the 440G-MZ safety switch.
When multiple guard locking devices are installed in a GuardLink system, the
GuardLink safety master inserts a short delay between commands to each successive device to minimize the momentary inrush current to the solenoids.
The device closest to the master receives the command first. The device furthest away from the master receives the command last.
See publication 440R-UM015 for more information.
