Dimensions in drawings

Unless otherwise indicated, all dimensions are stated in millimetres (mm).

171019 v2.00-RiA Operating instructions SG-RST 153 Page 5/15

Safety

Without a test signal, the control unit corresponds only to category 1.

The control unit is designed only for safety edges with an 8k2 monitoring resistor.

Safety mats and safety bumpers may not be connected.

The performance level PL is dependent on the output of the connected load. PL d can

also be achieved in some cases. We will be glad to assist you.

Intended use

The control unit is designed for signal processing of a pressure-sensitive protective

device. It evaluates the output signals of sensors with monitoring resistor 8k2. The

integrated output signal switching device (OSSD) transmits the evaluated safety sig-

nals directly to the downstream control.

The product complies with ISO13849-1:2015 Category2 PLc. So that the safety

classiﬁcation is retained, the downstream control must be of the same or a higher

category.

Safety

Safety instructions

ÄDo not use in ATEX zones

Do not use the Control Unit in potentially explosive environments (ATEX). The

control unit is not authorised for use in these zones.

ÄDisable in case of error

Disable the safety device in case of malfunctions or visible damage.

ÄPrevent restarting of the machine

As long as a hazard continues to exist, take measures to prevent the machine

from restarting, for example by means of a startup lockout.

ÄPrevent electric shock

When working on electrical systems, always disconnect them from the power

supply and secure them against being switched on again, to prevent injuries from

electric shock.

For your own safety the following safety instructions apply.

ÄEnsure careful conﬁguration of interface

The quality and reliability of the interface between the safety device and the ma-

chine aects the overall safety. Take special care when setting up this interface.

Safety

Terminals X1 to X2 are not potential-free.

ÄDo not modify the control unit

Never manipulate or make changes to the control unit.

Residual dangers

There are no known residual dangers associated with this product.

ÄDo not cross link control unit

Do not cross link the control unit with other control units.

ÄFit spark absorbers

When connecting inductive loads, ﬁt spark absorbers (RC modules) to the con-

sumer.

ÄCheck supply voltage

Check supply voltage. It must correspond with the connecting voltage USon the

type plate.

ÄObserve pin assignment

Observe pin assignment when connecting the supply voltage.

ÄProtect relay contacts

Risk of welding: Protect the relay contacts externally.

ÄDo not overload control unit

Ensure that the speciﬁed switching current is not exceeded.

ÄDo not exceed the maximum number of sensors

Do not connect more sensors on the control unit, than the number speciﬁed in

the installation instructions of the sensors.

ÄMaintain distance

When installing in the switch cabinet, ensure sucient distance from heat sourc-

es (at least 2 cm).

ÄObserve degree of protection

Only use the control unit in rooms with a minimum degree of protection of IP54

(e.g. switch cabinet).

To prevent irreparable damage to the product, the following safety instructions ap-

ply.

Operation

•red LED „FAULT“:

Cable break

•yellow LED „SENSOR“:

Sensor actuated or testing

•green LED „POWER“:

Supply voltage connected

The control unit can be operated with AC/DC 12 to 24 V or AC 230 V. If supply volt-

age is connected, the green “POWER” LED lights up. The control unit now monitors

the connected sensor, which must be equipped with an 8k2 monitoring resistor. In

sensors that are not actuated, relay K1 energizes and switching channel 1 is closed. If

the sensor is actuated, relay K1 de-energizes, the yellow “SENSOR” LED lights up, and

switching channel 1 is opened. In case of a cable break, relay K1 de-energizes, the red

“FAULT” LED lights up, and switching channel 1 is opened.

Prior to any dangerous movement the safety function of the sensor must be moni-

tored via an external test signal from the machine control.

Without a test signal, the control unit corresponds only to category 1.

Automatic reset

1. Mount the sensor in the desired position using screws with a diameter of 4 mm.

To do so, remove the enclosure cover.

Operation

The control unit operates without a reset function. If the sensor is released after actu-

ation, relay K1 energizes again with a delay of tw. (see reactivation time twin chapter

Installation

For your safety, the generally accepted safety rules also apply for assembly:

•Disconnect all devices and live parts in the immediate vicinity from the power

supply.

•Ensure that all devices and live parts cannot be switched back on.

•Test to ensure that all devices and live parts are disconnected from the power

supply.
