Rockwell Automation Allen-Bradley Guard master MC2 Bedienungsanleitung

Product Information

Original Instructions

Magnetically Coded Non-contact Switch (MC2)

Catalog Numbers 440N-Z21W1PA, 440N-Z21W1PB, 440N-Z21W1PH

Wiring

Recommended Mating Cable

The standard cable lengths are 2 m, 5 m, and 10 m. Use catalog number 889D-F8AB-2 [2 m (6.5 ft)] for the

standard length. Replace the 2 with 5 [5 m (16.4 ft)] or 10 [10 m (32.8 ft)] for other standard cable lengths.

Status/Diagnostic Indicator

Mounting Information

Use nonremovable screws, bolts, or nuts to mount the switch and actuator. Do not over torque the

mounting hardware. It is recommended to use M3 screws and washers throughout.

Maximum torque is 1 N•m (8.86 in•lb). Use nonmagnetic mounting hardware.

Position the switch and actuator so they are aligned with each other.

Mounting for Maximum Misalignment

Mount the sensor to the fixed part of the guard and the actuator to the movable section. Keep the sensor

and actuator within the sensing range detailed as shown in Figure 3 on page 2.

Minimum distance between sensors is 50 mm (1.97 in.).

ATTENTION: Read this document and the documents that are listed in

Additional Resources on page 2 about installation, configuration, and

operation of this equipment before you install. Users are required to

familiarize themselves with installation and connection instructions and

requirements of all applicable codes, laws, and standards.In accordance with

applicable codes of practice, suitably trained personnel are required to

implement installation, adjustments, service initiation, use, assembly,

disassembly, and maintenance. If this equipment is used in a manner that the

manufacturer does not specify, the protection that is provided by the

equipment may be impaired.

ATTENTION: The presence of spare actuators can compromise the integrity

of safety systems. Personal injury or death, property damage, or economic

loss can result. Appropriate management controls, working procedures, and

alternative protective measures should be introduced to control their use and

availability.

WARNING: Do not defeat, tamper, remove, or bypass this unit. Severe injury to

personnel could result.
