Coded Magnetic Safety Switch ZCode -LC
User Information

English translation

Correct Use

ZCode-LC is a coded tamperproofed magnetic safety switch with
transistor output. It is simple to install, IP67 dust- and waterproofed and has no moving or touching parts. Anything other
than the ZCode actuator will not trigger the switch. In combination with a dual channel ZANDER safety relay or ZANDER safety
PLC the switches are selfmonitoring with short-circuit protection.

Features

• Coded sensor with switch indication LED
• 2 non-contact safety outputs
• Easy to install
• Wide tolerance to guard misalignment
• Protection IP67
• Safety categorie 4 - for single connection to a ZANDER

safety relay
• Upt to PL e, Kat. 4 according to EN ISO 13849-1
• For applications with high protection and hygiene requi-

rements, e.g. food industry

• High operational life without moving or touching parts

Function

Coded magnetic non contact safety switches ZCode are
designed to interlock hinge, sliding or removal guard doors
(see Fig. 1).
The outputs of the ZCode will be switch off, if the guard
door is opened. The connected safety relay will open the
safety contacts immediately.
The ZCode safety switches have a magnetic sensing system 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 from 4 directions even in extreme environments of
temperature and moisture.

Precautions

Electrical
Connection

M4 mounting bolts must be used to fix the switches and
actuators. Tightening torque for mounting bolts to ensure
reliable fixing is 2Nm. Always mount on to Non Ferrous
materials. The recommended setting gap is 5mm.
The safety switches must not be used as a mechanical
stop. The actuators must not be allowed to strike the
switch. An adjustment by striking with a hammer is inadmissible. Do not mount adjacent switches or actuators
closer than 30mm. Typical misalignment tolerance after
setting is 5mm in any plane.

• Installation and commissioning of the device must be

performed only by authorized personnel.
• Observe the country-specific regulations when installing
the device.
• The electrical connection of the device is only allowed to
be made with the device isolated.
• 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.

The installation of all ZCode - safety switches must be in
accordance with a risk assessment for the individual application. For monitoring the ZCode switches, the two redundant outputs must be connected to a safety emergency
stop relay (e.g. ZANDER SR“C“) or a dual channel connection has to be made with the inputs of a safety PLC.

• It is not allowed to open the device, tamper with the devi-

ce or bypass the safety devices.
• All relevant safety regulations and standards are to be

observed.
• The overall concept of the control system in which the

device is incorporated must be validated by the user.
• Failure to observe the safety regulations can result in

death, serious injury and serious damage.
