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.
WARNING
Failure of the safety function
When used outside of the defined environmental conditions, the safety-related function of the sensor cannot be guaranteed.
▶ Use only in accordance with the defined environmental conditions ( 9 Technical data).
Use of the sensor in the vicinity of chemical and biological media (solid, liquid, gaseous) as well as ionising radiation is not permitted.
UK
Observe the following requirements:
▶ Take measures to avoid metallic objects being placed on the sensing face unintentionally.
▶ Adhere to EN 14119 for interlocking devices associated with guards.
▶ 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 original instructions GF711S, ident no. 11491846.
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 GF711S 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 s_ar ( 9 Technical data).
Also observe the notes on installation of the sensor ( 6 Installation).
The fail-safe inductive sensor is a proximity device with defined behaviour under fault conditions (PDDB) to IEC 60947-5-3.
The fail-safe sensor conforms to Performance Level d according to EN ISO 13849-1 as well as to the requirements SIL 2 to IEC 61508 and meets SILcl 2 to IEC 62061.
The unit corresponds to the classification I2A12SP2 to IEC 60947-5-2 for non-flush installation ( 6 Installation).
The fail-safe inductive sensor has been certified by TÜVNord.
5 Function
1: dual LED: signal (yellow); power (green)
2: close zone
3: enable zone
4: safe switch-off distance s_ar
5: target
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.
The safe switch-off distance s_ar is > 6 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 selected materials*:
| Material Enable zone |
| FE360 (= mild steel) 0.5...4 mm |
| Stainless steel 0...3.1 mm |
| AIMg3G22 0...1.8 mm |
| CuZn37 0...2.0 mm |
| Copper 0...1.2 mm |
* Typical values for damping with a reference target of 12 x 12 x 1 mm and non-flush installation to IEC 60947-5-2 at an ambient temperature of 20 °C.
Depending on the characteristics of the damping element there may be no close zone.
6 Installation
The unit is non-flush mountable according to IEC 60947-5-2, type I2A12SP2.
▶ Ensure the unit cannot work loose (tightening torque ≤ 7 Nm).
▶ Adhere to the installation conditions in accordance with the figures 1 to 3:
▶ Tighten the socket according to the manufacturer's indications. Observe the tightening torque for the ifm socket (e.g. EVxxxx: 0.6...1.5 Nm).
Flush installation of the fail-safe sensor is not permitted since this can result in an increase of the sensing range up to enabling of the outputs (OSSDs).
6.1 Protection against simple defeating
The fail-safe sensor reacts to metal objects, e.g. the frame of a safety door. Other metal objects that are not intended to enable the sensor must not be allowed to enable the fail-safe sensor unintentionally.
▶ Take measures to prevent metal objects, except the designated target, from being placed on the sensing face or in the enable zone unintentionally.
7 Electrical connection
▶ 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 a maximum of 40 V DC. (This requires the safe separation between power supply and transformer.)
1: safety-related logic unit *
* When there is no current flow on the output stage, back feeding > 3.5 V will lead to malfunction.
8 Operation
8.1 Switching state of the outputs
8.1.1 The safe state
The safe state is when at least one of the outputs A1 or A2 (OSSDs) is switched off (zero-current state: logic "0").
If one of the outputs A1 or A2 is switched off, the subsequent safety-related logic unit must bring the complete system into the state defined as safe.
8.1.2 The switched state
If the damping element is in the enable zone and if there is no sensor error, both outputs A1 and A2 (OSSDs) are enabled (logic "1").
8.1.3 Output characteristics
The output characteristics are compatible with the input characteristics to EN 61131-2 type 1 or 2:
Logic "1" ≥ 15 V 2...15 mA
≥ 11 V 15...30 mA
Logic "0" ≤ 5 V leakage current 0.2 mA
8.1.4 Cross fault / short circuit
- A cross fault between both outputs (A1 and A2) is detected by the fail-safe sensor and results in the outputs (OSSD) being switched off at the next safety request. The outputs A1 and A2 remain switched off until the error has been removed or a voltage reset has been carried out.
- A cross fault (short circuit) between output A2 and the supply voltage results in the other output A1 being switched off in case of a safety request.
- When there is no current flow on the output stage, back feeding >3.5V will lead to malfunction.
- The device carries out self-tests for the switch-off capability on A2.
