Correct Use
SR10.AD is an emergency stop safety relay combination that
combines non-time-delayed and time-delayed contacts
in a very
compact housing. This permits dangerous components of a
system to be switched off quickly and safely in an emergency
situation. At the same time, other circuits can continue to be
supplied with voltage for up to 30 seconds to allow a tool to be
moved to its idle position or to brake following parts, for exam-
Features
•
4 positively driven safety relays contacts. Possible vari-
ants:
- 3 non-time-delayed and 1 time-delayed contact
- 2 non-time-delayed and
2 time-de
layed contact
- 1 non-time-delayed and 3 time-delayed contact
•
Continuously adjustable time delay (1 bis 30s)
•
Connection of:
- emergency stop buttons
- sa
fety switches
- non-contacts safety switches
- OSSD-Outputs
•
1- or 2-channel activation possible
Function
The moving parts of a machine or system can be quickly
and safely stopped in case of danger with the non-time-
delayed contacts of the SR10.AD.Safety contacts with time
-delay switch-off are also integrated into the
SR10.AD. They are used whenever it is safer to keep
supplying voltage to parts of a machine after the emer-
gency stop switch is operated.
It is ensured that a single fault or malfunction does not lead
to a loss of the safety function and that every fault is de-
tected by cyclical self-monitoring no later than when the
•
It is not allowed to open the device, tamper with the devi-
ce or bypass the safety devices.
•
All relevant safety regulations and standards are to be
observed.
•
The overall concept of the control system in which the
device is incorporated must be validated by the user.
•
Failure to observe the safety regulations can result in
death, serious injury and serious damage.
Installation
As per DIN EN 60204-1, the device is intended for installa-
tion in control cabinets with a minimum deg
ree of protection
of IP54. It is mounted on a 35-mm DIN rail according to
DIN EN 60715 TH35.
Safety
Precautions
•
Installation and commissioning of the device must be
performed only by authorized personnel .
•
Observe the country-specific regulations when installing
the device.
•
The electrical connection of the device is only allowed to
be made with the device isolated.
•
The wiring of the device must comply with the instructi-
ons in this user information, otherwise there is a risk that
the safety function will be lost.

system is switched off and switched on again.
The time-delay contacts are activated at the same time as
the non-time-delay contacts; however, when the emer-
gency stop button is pressed, the contacts are only deacti-
vated after the time set on the potentiometer (1 … 30s).
Electrical
Connection
•
A control transformer according to EN 61558-2-6 or a
power supply unit with electrical isolation from the mains
must be connected.
•
External fusing of the safety contacts (6A slow-blow or
8A quick-action or 10AgG) must be provided.
•
A maximum length of the control lines of 1000 meters
with a line cross section of 0.75 mm
2
must not be excee-
ded.
•
The line cross section must not exceed 2.5 mm
2
.
•
If the device does not function after commissioning, it
must be returned to the manufacturer unopened. Ope-
ning the device will void the warranty.
