4 Functions and features

The fail-safe inductive sensor GI701S 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 . ( 10 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 e according to EN ISO 13849-1 as well as to the requirements SIL 3 to IEC 61508 and meets SILcl 3 to IEC 62061.

The unit corresponds to the classification I2A30SP2 to IEC 60947-5-2 for non-flush installation ( 6 Installation).

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

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 > 30 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) 6...12 mm

Stainless steel 3.8...8.8 mm

AIMg3G22 0.7...4.8 mm

CuZn37 1...5.2 mm

Copper 0...3.7 mm

* Typical values for damping with a reference target of 45 x 45 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.

5.2 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.

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 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 setting aid is activated ( 8.1).

Release of the enable zone can be carried out

• either by undamping (> 30 mm) for a time of more than 2 s
• or by a voltage interruption (→ 8.3 Deactivate setting aid).

6 Installation

The unit can be non flush mounted according to IEC 60947-5-2, type I2A30SP2.

▶ Ensure the unit cannot work loose (tightening torque ≤ 50 Nm).
▶ Adhere to the installation conditions in accordance with the figures 1 to 3:

1 2 3 30 30 90 30 240 60

▶ 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).

7 Electrical connection

Wiring diagram → 10 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 one fault the supply voltage must not exceed 60 V DC for more than 0.2 s up to a max. value of 120 V DC. (This requires the safe separation between power supply and transformer.)

8 Set-up

8.1 Setting aid

For easy and reliable installation the sensor features an optical setting aid to visualise the enable zone.

① ② 0 > 5 s Signal Power 30 mm

The setting aid is activated by placing a metal object in front of the fail-safe sensor (close range).

After approx. 5 s the yellow LED starts to flash: the setting aid is active.

While this mode is active, the output remains in the safe state ("0").

1: close zone
2: enable zone

8.2 Determine the enable zone

When the setting aid is active, the enable zone can be determined by moving the target (or the sensor if the target is fixed).

① ② 0 30 mm Signal Signal Signal Power Power Power Power

As soon as the target enters the enable zone, the yellow LED goes out. If the target is just outside the enable zone in either direction the LED starts to flash again.

1: close zone
2: enable zone

8.3 Deactivate setting aid

① ② 0 30 mm < 2 s Signal ● Power > 2 s ○ Signal ● Power

If the sensor is undamped for more than 2 s (> 30 mm), the setting aid is switched off and the yellow LED goes out.

This can also be achieved by power off.

1: close zone
2: enable zone

9 Operation

9.1 Switching state of the outputs

9.1.1 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.

9.1.2 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").

9.1.3 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 *) 

*) pull-down current typ. 30 mA

9.1.4 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 one of the two outputs (A1 or A2) and the supply voltage results in the other output (A2 or A1) being switched off in case of a safety request.

9.2 Operating mode

The length of the preceding undamping determines whether the yellow LED comes on with a delay ( 9.2.1) or without delay ( 9.2.2) when a target moves into the enable zone. In any case, the outputs switch on without delay.

In case of undamping the outputs switch off and the yellow LED goes out without delay.

In case of damping in the close range the outputs switch off immediately whereas the yellow LED goes out with a delay of approx. 2 s.

When the LED goes out the outputs are maintained in the safe state ("0"). Thus, switching on again in the enable zone is not possible. Enabling is done by undamping (> 30 mm) of more than 2 s or by interrupting the voltage ( 5.2 Protection against simple defeating).

9.2.1 Delayed switching of the LED

Undamping > 2 s: ① ② 0 30 mm > 3 s Signal Power

If the target was away from the sensor for more than approx. 2 s (>30 mm), the yellow LED goes on with a delay of approx. 3 s in case of damping in the enable zone.

This is also the case if the target is in the enable zone when the voltage is switched on.

1: close zone
2: enable zone

9.2.2 Switching of the LED without delay

Undamping < 2 s: ① ② 0 30 mm ≈ 0 s*) Signal Power

If the target was away from the sensor for less than 2 s (> 30 mm), the yellow LED comes on without delay in case of damping in the enable zone.
