Non Contact Stand Alone Coded Safety Switches
MAINTENANCE:
Weekly: Check alignment of actuator and look for signs of mechanical damage to the switch casing. Check wiring for signs of damage.
Monthly: Check each switch function by opening and closing each guard individually in turn and ensuring that the Green LED on the switch is illuminated when the switch is closed and
extinguished when the switch is open. Check that the machine stops and cannot be re-started when each switch is open.
Never repair any switch, actuator or integral cables. Replace any switch displaying signs of mechanical damage to the casing or cables.
IMPORTANT NOTE:
Read and understand these instructions before installing, operating, or maintaining this equipment.
The product is designed to be a component of a customised safety orientated control system. It is the responsibility of each manufacturer to ensure the correct overall functionality of its
systems and machines. IDEM, its subsidiaries and affiliates, are not in a position to guarantee all of the characteristics of a given system or product not designed by IDEM.
APPLICATION:
Coded Non Contact switches are designed to interlock hinged, sliding or removal guard doors. They are specifically advantageous when:
a)
poor guard alignment exists
b)
anti-tamper is required
c)
high hygiene requirements exist e.g. food industry hose down
d)
a long mechanical life is required (no moving or touching parts).
The PSA/MSA Coded Non Contact Switches can be used to provide protection up to Category 4 and Ple to ISO13849-1.
OPERATION:
All Coded Non Contact Safety Switches are designed to conform to EN60947-5-3 (PDF-M) and be used as directed by EN1088, EN ISO12100 and EN 60204-1. They have coded
magnetic sensing which provides a wide (>10mm) sensing distance and provides a high tolerance to misalignment after sensing. They can be fitted behind stainless steel fittings and can
operate in extreme environments of temperature and moisture.
INSTALLATION:
Installation of all Coded Non Contact Switches must be in accordance with a risk assessment for the individual application.
The PSA/MSA internally monitor 2 redundant circuits as per ISO13849-1 for up to Ple/Category 4 protection.
M4 mounting bolts must be used to fix the switches. Tightening torque for mounting bolts to ensure reliable fixing is 1.0 Nm. Always mount on to Non Ferrous materials.
The recommended setting gap is 5mm. The Safety switch must not be used as a mechanical stop or be adjusted by striking with a hammer.
The actuator must not be allowed to strike the switch. Do not mount adjacent switches or actuators closer than 30mm.
Typical misalignment tolerance after setting is 5mm.
After installation always check each switch function by opening and closing each guard individually in turn and ensuring that the Green LED on the switch and the LED’s on the Safety
Relay are illuminated when the switch is closed and are extinguished when the switch is open. Check that the machine stops and cannot be re-started when each switch is open.
ACTUATOR OPENING DIRECTIONS: DIMENSIONS:
Align actuator and switch using the target lines. All dimensions in mm.
