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

Please refer to the operating manual for installation and operation. ][Wichtig_PDB Service life graph The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negligible.
