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 LE 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. I EM, its subsidiaries and affiliates, are not in a position to guarantee all of the characteristics of a given system or product not designed by I EM.
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 (P F-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 Ferrou
s 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. o 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 LE on the switch and the LE ’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.

CONNECTION EXAMPLE: Switches in series PLe Cat.4
Two switches connected in series to give dual circuit safety outputs to machine contactors.
Safety Circuit 1 (Black/White) utilises internally checked force guided relay contacts and is
connected in series with the corresponding Safety Circuit 2 (Yellow/Green) of the next
switch.
Allows minimal wiring and higher current switching to K1 and K2 contactors.
A manual start and contactor feedback check is achieved by connecting K1(Aux) and
K2(Aux) feedback contacts and momentary start button through the orange and brown
feedback check.
SAFETY PRECAUTIONS:
1. Installation and commissioning of the device must be performed only
by authorised ersonnel.
2. Observe the country specific regulations when installing the device.
3. The wiring of the device must comply with the instructions in this user
information - otherwise there is a risk that the safety function will be lost.
4. External fusing of the safety contacts (a slow blow or 6A quick action
must be provided).
5. All relevant safety regulations and standards are to be observed.
6. The overall concept of the control system in which the device is
incorporated must be validated by the user.
7. Failure to observe the safety regulations can result in death, serious
injury and serious damage.
8.
Always use Safety Output 1.
