Unit description
][Gertebeschreibung_Zweihand
The two-hand control relay meets the
requirements of EN 574 Type IIIC. It
forces the operator to keep his hands
outside the danger zone area during
the hazardous movement. The unit is
suitable for use on controllers for met-
alworking presses as a component for
simultaneous switching.
It can be used in applications with
`
Mechanical presses (EN 692)
`
Hydraulic presses (EN 693)
`
Safety circuits in accordance with
EN 60204-1
Safety features
][Sicherheitseigenschaften_Zweihand
The two-hand control relay meets the
following safety requirements:
`
The circuit is redundant with built-in
self-monitoring
`
The safety function remains effec-
tive in the case of a component fail-
ure
`
The circuit prevents a further press
stroke in the case of:
– Relay failure
– Contact welding
– Coil defect on a relay
– Open circuit
– Short circuit
