complied with�

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

• 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 setup the system has to be subjected to 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�

• Use only as described below (→ 4 Functions and features)�

2.1 Safety-related requirements regarding the application

It must be ensured that the safety requirements of the respective application

correspond to the requirements stated in these instructions�

Observe the following requirements:

► Take measures to avoid metallic objects being placed on the sensing face

intentionally or unintentionally�

► Adhere to EN 1088 for interlocking devices associated with guards�

► Adhere to the specified operating conditions (→ 11 Technical data)� Use of

the sensor in the vicinity of chemical and biological media as well as ionising

radiation is not permitted�

► Adhere to the principle of normally closed operation for all external safety

circuits connected to the system�

► In case of faults within the fail-safe sensor which result in the defined safe

state: take measures to maintain the safe state when the complete control

system continues to be operated�

► Replace damaged units�

3 Items supplied

1 fail-safe sensor GM705S with premounted angle bracket,

1 Allen key for fixing the fail-safe sensor onto the angle bracket,

1 operating instructions GM705S, ident number 704241�

If one of the above-mentioned components is missing or damaged, please contact

one of the ifm branch offices�

4 Functions and features

The fail-safe inductive sensor GM705S detects metal without contact�

Safety function SF: The safe state (output stage switched off; logic "0") is achieved

when undamping greater than or equal to the safe switch-off distance sar

(→ 11 Technical data)�

Also observe the notes on installation of the sensor (→ 6 Installation)�

The fail-safe sensor conforms to the category 4 according to EN 954-1 (valid until

31 December 2011), Performance Level e according to EN ISO 13849-1:2008 as

well as to the requirements SIL 3 to IEC 61508 and meets SILcl 3 to IEC 62061�

The unit corresponds to the classification I2C40SP2 to IEC 60947-5-2 for non-

flush installation (→ 6 Installation)�

The fail-safe inductive sensor has been certified by TÜVNord�

5.1 Enable zone

The outputs (OSSD) are only enabled when a damping target is present in the

enable zone� Outside this enable zone the outputs remain switched off�

If damped with a standard target plate of 60 x 60 x 1 mm made of FE360 (= mild

steel) and non-flush installation to IEC 60947-5-2, the enable zone is in the range

of ≤ 4 �� ≥ 20 mm�

The safe switch-off distance sar is > 45 mm�

The enable zone is different if damping elements which deviate from the standard

target plate in terms of material, form and size are used�

Enable zone for other materials*:

stainless steel 2�0��17�6 [mm]

AIMg3G22 0��9�6 [mm]

AI 99 % 0��8�6 [mm]

CuZn37 0��10�0 [mm]

copper 0��7�0 [mm]

* Typical values for damping with a reference target of 60 x 60 x 1 mm and non-flush

installation to IEC 60947-5-2 at an ambient temperature of 20°C�

5.2 Protection against simple defeating

The fail-safe sensor reacts to metal objects, e�g� the frame of a security door�

Other metal objects that are not intended to enable the sensor must not be

allowed to enable the fail-safe sensor, either intentionally or unintentionally�



► Take measures to prevent metal objects, except the designated target,

from being placed on the sensing face or in the enable zone intentionally

or unintentionally�

In addition, the sensor has the following switching characteristics to make simple

defeating of its safety function more difficult:

1� By slowly introducing a metallic object into the enable zone, the outputs are

immediately switched, but displayed by the LED with a delay of approx� 3 s

(→ 9�2�1 Delayed switching of the LED)� By doing so, the object is generally

in the close range before the LED indication is lit� The technical instructions

concerning the restart of the installation must be observed�

2� If the metal object remains in the close zone for over approx� 2 s, the outputs

are completely disabled and no longer enabled in case of damping in the

enable zone� If the object stays in the close range for longer than approx� 5 s,

the adjustment mode is activated (→ 8�1 Activate adjustment mode)�

Release of the enable zone can be carried out

• by undamping (> 45 mm) for over 2 s

• or by power off

(→ 8�3 End adjustment mode)�

6.2 Installation conditions

The unit is non-flush mountable according to IEC 60947-5-2, type I2C40SP2�

► Ensure the unit cannot work loose�

► Tighten captive screws with 1 Nm�

► Limit the use of oblong holes to the initial setting�

► Adhere to the installation conditions in accordance with the figures 1 to 4:

7 Electrical connection

Wiring diagram (→ 11 Technical data)

► Disconnect power� Also disconnect any independently supplied relay load

circuits�

► Supply voltage: Connect L+ to pin 1 and L- to pin 3 of the connector�



The nominal voltage is 24 V DC� This voltage may vary between 19�2 V and

30 V incl� 5% residual ripple to EN 61131-2�



In case of a single fault the supply voltage must not exceed 60 V DC

for over 0�2 s up to a max� value of 120 V DC� (This requires the safe

separation between power supply and transformer�)



For unit with cULus approval and the scope of validity cULus:

The device shall be supplied from an isolating transformer having a

secondary listed fuse rated either

a) max� 5 amps for voltages 0~20 Vrms (0~28�3 Vp) or

b) 100/Vp for voltages of 20~30 Vrms (28�3~42�4 Vp)�

8 Set-up

8.1 Activate adjustment mode

For easy and reliable installation the sensor can be put in the adjustment mode�

> 5 s

Signal

Power

This is done by placing a metallic

object directly in front of the sensing

face of the fail-safe sensor (close

range)�

After approx� 5 s the yellow LED

starts to flash: The adjustment mode

is active�

As long as this mode is active the

output stages remain in the safe

state�
