Activation switch

In the wiring diagram above (page 200), the activation switch has the designation (K).
This represents a component such as a manually operated switch, an emergency
stop push button switch, or the contacts of a safety relay or safety PLC.
• If a manually operated activation switch is used, the switch must be of a type that
can be locked out to the open position.
• Inputs IN1 and IN2 must open/close within 200 ms of each other.
