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
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 failure
The circuit prevents a further press
stroke in the case of:
– Relay failure
– Contact welding
– Coil defect on a relay
– Open circuit
– Short circuit
Install base unit without contact expander module:
Ensure that the plug terminator is
inserted at the side of the unit.
Connect base unit and PNOZsigma
contact expander module:
Remove the plug terminator at the
side of the base unit and at the contact expander module.
Connect the base unit and the con-
tact expander module to the supplied connector before mounting
the units to the DIN rail.
Installation in control cabinet
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 (35 mm).
When installed vertically: Secure
the unit by using a fixing element
(e.g. retaining brakket or end angle).
Push the unit upwards or down-
wards before lifting it from the DIN
rail.
CAUTION!
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 movement 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.

To increase the service life, sufficient
spark suppression must be provided
on all output contacts. With capacitive
loads, any power surges that occur
must be noted. With contactors, use
freewheel diodes for spark suppression.

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