Notes for Operation
When using the XN emergency stop switches in safety-related part of a control
system, observe safety standards and regulations of the relevant country or
region. Also be sure to perform a risk assessment before operation.
Wiring
Tighten the M3 terminal screws to a torque of 0.6 to 1.0 N·m.
Contact Bounce
When the button is reset by pulling or turning, the NC main contacts will bounce.
When pressing the button, the NO monitor contacts will bounce.
When designing a control circuit, take the contact bounce time into consider-
ation (reference value: 20 ms).
LED Illuminated Switches
LED lamp is built into the contact block and cannot be replaced.
Handling
Do not expose the switch to excessive shocks and vibrations, for example by
operating the switch with tools. Otherwise the switch may be deformed or dam-
aged, causing malfunction or operation failure.
