Frequently Asked Questions - Testavit Schuki 2K Testboy

How to connect the Testavit Schuki 2K to a socket?

Turn switch S1 to OFF, then plug the device into the socket to be checked. Ensure that the phase is on the left contact of the connector (view from the display).

What to do if no lamp lights up after connection?

If no lamp lights up, touch the contact electrode GL1. If still nothing, the phase conductor is not connected. If a lamp lights up dimly, the phase is present but the wiring is incorrect. Check the device connection.

How to test a residual current circuit breaker (RCD)?

Plug the tester into a correctly wired socket. With selector S1, choose the rated fault current (10-500 mA). Press the T button: the fault current flows for 200 ms. If the RCD works, it trips and all lamps go out.

What do the lamps in the yellow zone mean?

Lamps L1 (phase), PE (protection), and N (neutral) indicate conductor connection. The combination of lit/unlit lamps diagnoses the socket wiring.

What if the GL1 lamp does not light up when touching the electrode?

This means the device is incorrectly connected or the socket is wrongly wired. Turn the Schuki 2 by 180° and reconnect. If the problem persists, the phase is likely on the protection contact.

What is the meaning of lamp L3?

Lamp L3 (green zone) indicates the residual current circuit protection test. It lights up when the T button is pressed during an RCD test.

How to interpret the fault 'missing neutral conductor'?

If lamps L1 and PE light up and GL1 lights up when touched, the neutral conductor is missing. In this case, the phase and protection conductors may be reversed. Refer to the figures in the manual.

Can I test an RCD without earth?

Yes, the check can be performed on installations without differential protection, but the RCD test will only work if an RCD is present.

What is the operating voltage of the device?

The device operates at 230 V AC, 50 Hz.

How to clean the Testavit Schuki 2K?

Use a dry, soft cloth. Never use solvents or abrasive products.

The Schuki 2 is a test device for testing socket outlets, cable connections and circuits protected by earth-leakage circuit breakers (ELCB) in 230-V systems as well as older installations with classic 'protective multiple earthing'. Socket outlets and connecting cables are tested for correct wire connections.

The effectiveness of ELCB protected circuits is tested by calibrating the nominal fault current.

Device description

The Schuki 2 is plugged straight into the socket outlet to be tested in the installation. The touch electrode on the top of the housing functions according to the same principle as a phase tester.

Functions

The Schuki 2 (figure 1) is divided into three areas:

■ The red warning area indicates the function of the protective earth.
■ The yellow testing area indicates the wiring connections.
■ The green area is responsible for the earth-leakage circuit breaker (ELCB).

The status of the protective circuit of the socket being tested is indicated by a combination of glowing and non-glowing lamps.

The lamps and their meanings

In the yellow area:
L1 Phase conductor
PE Protective earth
N Neutral conductor
In the red area:
L2 Protective earth
GL1 Touch electrode
In the green area: L3 ELCB protected circuit

Control elements

Two elements available for testing the ELCB circuitry.

■ (S1) Rotary switch to adjust the nominal fault current
■ (T) A button to trigger the nominal fault current

The touch electrode tests the phase conductor according to the principle of a phase tester.

Symbols used in this documentation

To provide a better overview, images are used to enhance the descriptions of faults. For this purpose, the following symbols are used:

■ Symbol not shaded:
The lamp is not glowing or the button has not been pressed
■ Symbol shaded:
The lamp lights up or the button has been pressed
■ Plug symbol for test results:
The recognised circuitry is portrayed.

■ Danger symbols:

The recognised circuit is a danger to life.

Checking socket outlets and connecting wires

The test is the same for both socket outlets and connecting wires. For this reason, only socket outlets are mentioned in this documentation.

The device is very easy to operate: turn the switch S1 to OFF, and plug the device into the socket outlet to be tested. You should ensure that the phase conductor connects to the left-hand pin (viewed when device is inserted and faceplate visible).

Checking the correct position

The device is ready to use for testing when the touch electrode is touched and the lamp GL1 lights up. If it doesn't, either the device has been incorrectly inserted or the socket outlet has been incorrectly wired. Rotate the Schuki 2 180°, then re-insert into the socket and re-check the positioning.

You must observe the fault depicted in figure 9.

Fault indication

No current flowing

None of the lamps light up. Touch the touch electrode as well. Should none of the lamps light up, the phase conductor is not connected.

If one of the lamps in the yellow area glows, then the phase conductor is connected to the respective connection.

The phase conductor is not contacting the left-hand pin of the test device (viewed when device is inserted and faceplate visible); it cannot be tested. Rotate the Schuki 2 180° and re-insert.

Testing the ELCB protected circuit

Insert the testing device into a socket outlet and test the circuitry. If no fault is indicated, you can begin testing the ELCB function.

Using the switch S1, adjust the nominal fault current to the required value; press the button T. The nominal fault current flows for 200 ms.

Note:

This test can also be carried out in systems not fitted with an ELCB.
■ It is permitted to press the button T once every 10 seconds only.

Please refer to the first fault indication FI, if the ELCB is not tripped.

In addition, L3 lights up when the button T is pressed; simultaneously the PE lamp goes out.

The lamps go out when the ELCB is tripped.

The protective earth conductor has an increased but permissible resistance.

The fault is indicated as portrayed in figure 10.

In this case the ELCB is not tripped, the lamps in the yellow area continue to glow.

Protective earth resistance too high
Figure 12: All lamps in the yellow area light up. In addition, L3 lights up when the button T is pressed. Simultaneously, the PE lamp goes out, and L2 flashes on for short period.

L3 goes out after 200 ms; the lamps in the yellow area continue to glow. The ELCB is not tripped.

The resistance of the PE conductor in unacceptably high. Life threatening voltages can build up at the earthing contact!
