Also adhere to the safety instructions for the operation of the whole installation.

• In case of non-observance of notes or standards, especially when tampering

with and/or modifying the unit, any liability and warranty is excluded.

• The unit must be installed, connected and put into operation by a qualified

electrician trained in safety technology.

• The applicable technical standards for the corresponding application must be

complied with.

• For installation the requirements according to EN 60204 must be observed.

• Connect and lay all cables according to EN ISO 13849-2 D.5.2 (Safety of

machinery - Safety-related parts of control systems).

• In case of malfunction of the unit please contact the manufacturer. Tampering

with the unit is not allowed.

• Disconnect the unit externally before handling it. Also disconnect any

independently supplied relay load circuits.

• After installation of the system perform a complete function check.

• Usetheunitonlyinspecifiedenvironmentalconditions(→11Technicaldata).

In case of special operating conditions please contact the manufacturer.

If one of the above-mentioned components is missing or damaged, please contact
one of the ifm branch offices.

4 Functions and features

The device is a 2-channel pulse evaluation system for the safe detection of
underspeed or standstill of an object.

For evaluation, the device requires 2 pulse pick-ups (pnp-switching sensors
with "normally open" function).

The safe state is when the output contacts (13-14 and 23-24) of the device
are open.

ifm electronic gmbh does not assume any liability for the function and the
interaction of the device with devices from other manufacturers.

Suitability of the device for a certain application cannot be assured and
must be ensured by the user.

The device can be used in applications up to

• PL e according to ISO 13849-1

• SIL 3 according to IEC 61508

• SIL

CL

3 according to EN 62061

4.1 Requirements for the hardware configuration

The following requirements must be met when using the device:

4.1.1 Product-independent requirements

It must be ensured that the safety requirements of the respective application
correspond to the requirements stated in these instructions.

The specified technical data indicated in these instructions must be complied with.
The principle of normally closed operation must be applied to all external safety
circuits connected to the system.

The following points have to be ensured in the application by taking administrative
measures:

• The devices of type "safe standstill monitor", DA102S, in operation must be

subjected to a self-test (switching on) within a period of maximum 6 months
(intermittent operation).
The self-test starts when the supply voltage is applied.

(→7.2Supplyvoltage)

• The safety-relevant relay contacts have to be protected by respective fuses of

3.6 A as short-circuit/overload protection.

(→7.6Switchingoutputs14-23and24-24)

4.1.2 Product-dependent requirements

In case of faults within the device which result in the defined safe state, the device
must be replaced.

Any faulty unit should be returned to the manufacturer.

5.2 Operating principle

The device is a 2-channel pulse evaluation system for the safe detection of
underspeed or standstill. In this respect the device picks up the pulse sequences
of 2 connected pulse pick-ups.

The microprocessors calculate the resulting frequency. The device detects
underspeed as compared to the set switch point by constantly comparing the
frequency of the actual and the preset values.
