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 met­alworking 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

tive in the case of a component fail­ure

` The circuit prevents a further press

stroke in the case of:
– Relay failure

Installation

][Montage_Zweihand

` The safety relay should be installed

in a control cabinet with a protec­tion type of at least IP54.

` Use the notch on the rear of the unit

to attach it to a DIN rail.

` Ensure the unit is mounted securely

on a vertical DIN rail (35 mm) by us­ing a fixing element (e.g. retaining
brakket or an end angle).

Notice

The distance of the button connected
to the two-hand relay from the nearest
danger zone must be large enough
that if one of the buttons is released,
the dangerous moment is interrupted
before the operator can reach into the
danger zone (see EN 999 “The posi­tioning of protective equipment in re­spect of approach speeds of parts of
the human body”).

Service life graph

Lebensdauerkurve_Rela is_Text vor Kurv e

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.

Si-Kennzahlen_Zusatz_Relais_Lebensdauer_PDB

It is essential to consider the relay's
service life graphs. The relay outputs'
safety-related characteristic data is
only valid if the values in the service life
graphs are met.

The PFH value depends on the switch­ing frequency and the load on the relay
output. If the service life graphs are not
accessible, the stated PFH value can
be used irrespective of the switching

frequency and the load, as the PFH
value already considers the relay's
B10d value as well as the failure rates
of the other components.

Si_Kennzahlen_Erläute rung

All the units used within a safety function must be considered when calculating the safety characteristic data.
