FUNCTION
After the supply voltage is applied to terminals A1/A2 and the
safety inputs are closed, the enabling current paths (NO contacts)
are closed and the signal current path (NC contact) is opened by
pressing the reset button (manual start with monitoring). When the
safety inputs are opened/de-energized, the enabling current paths
(NO contacts) are opened immediately.
CIRCUIT DIAGRAM
• Manual start with monitoring – Reset input S34 is connected to
safety input S11 via a RESET button. To monitor external contact
blocks (EDM), their NC contacts must be connected in series to
the RESET button.
• Monitoring of light curtains – The KM device types are especially suitable for the monitoring of very fast tactile switching
operations, for example in safety light curtain applications. Very
short switch-off procedures of a few milliseconds are detected
reliably and lead to the switching off of the internal relays.
