Dual-channel Emergency Stop and Cable-pull Switch

Monitoring

Achievable safety rating

Cat. 4

DIN EN ISO 13849-1

PLe

DIN EN ISO 13849-1

SIL3

IEC 62061/61508

Stop category

EN 60204-1

Features

•

Dual-channel monitoring

•

Cross-connection detection

•

Start buton

•

Monitoring of external contactors (EDM)

Safety sensor/operating
mechanism

•

Emergency stop button

•

Cable-pull switch, latching

Notes

•

Manual reset

•

Autostart is possible if the NC circuits from
K3 and K4 are attached to 3.3 and 3.4.

Note:

All example applications shown are proposals without warranty. In any case the operator has

to perform a safety review of the entire site.

When the emergency stop button is pushed or the cable-pull switch is activated, the EP-19xx
switches off the 24 V supply for the modules (switchable modules refer to the section,

Contact Information

) within the safety segment and thus also contactors K3 and K4. The failure of a

switching element in the emergency stop button or the cable-pull switch as well as a cross-circuit in
their supply lines does not result in the failure of the emergency stop mechanism and is detected
within the fault-reaction time.
The EP-19xx module switches on the 24-V supply for the modules within the safety segment if:

•

Emergency button is unlocked

•

Cable-pull switch is unlocked

•

Feedback circuit (NC contacts of K3 and K4) is closed

•

Start push button has been pushed and released again

Contactors K3 and K4 are controlled by the PLC and can switch on as soon as the EP-19xx has
switched on the 24-V supply.
