Technical data

ing, the gray STOP switch is to prevent the operator from using the EMER‐
GENCY STOP switch when the manual operating terminal is disconnected; in
this case the EMERGENCY STOP switch has no effect.
WARNING
Non-functioning EMERGENCY STOP devices can have disasterous
consequences!
Red-yellow
marked EMERGENCY STOP switches must be in working order at
all times and for all modes of operation of a machine or a system.
Hand operated devices with a red-yellow EMERGENCY STOP switch that are
not connected to a machine must be stored in such a manner that they are not
visible and hence cannot be confused with functioning devices in the event of
an emergency.
For this reason, hand operated devices that are intended for frequent temporary
connection and disconnection to/from machines must not be equipped with a
red-yellow EMERGENCY STOP switch. Instead, the gray STOP switch is to be
used for such devices.
WARNING
A release of the EMERGENCY STOP device must not activate an un‐
controlled restart.
WARNING
The EMERGENCY STOP switch is not intended to dunction as a re‐
placement for safety devices.
WARNING
The EMERGENCY STOP switch on the hand-operated device is not
intended to function as a replacement for EMERGENCY STOP switches
which are to be directly fitted to the machine.
WARNING
Specific mechanical faults in the EMERGENCY STOP or the STOP
switches can only be detected on actuation.
The EMERGENCY STOP switch must also be tested cyclically (every 6
months)
by actuating the EMERGENCY STOP switch and observing whether
or not the machine shuts off.
The manufacturer guarantess a life span of >50,000 switching cycles.
