2 Introduction

The Personnel Grounding Tester PGT 120 is an electronic test instrument for checking personnel grounding systems such as wrist straps, coil cords and footwear. The PGT 120 is suitable for compliance verification of the above products, according to the IEC 61340-5-1 Edition 1.0 (2007-08) or ANSI/ESD S 20.20 – 2007 (2007-03).

• The unit operates with 3 independent measuring circuits for the left shoe, the right shoe and the wrist strap. This makes it possible to measure all the values at the same time
• It is possible to enable or disable separately the measuring
• The order of tests is
• Footwear measurement can be configured to measure in series with hands free for passenger gates.
• Visual and audible test results and a dry relay contact for door opener
• Use the optionally available "Calibration Unit " Part No. 7100.PGT120.CU to check the unit Hi and Lo limit values

2.1 Device return and environmentally compatible disposal

The instrument is a category 9 product (monitoring and control instrument) in accordance with ElektroG (German Electrical and Electronic Device Law). This device is not subject to the RoHS directive.

We identify our electrical and electronic devices (as of August 2005) in accordance with WEEE 2012/19/EU and ElektroG with the symbol shown to the right per DIN EN 50419.

3 Installation

The Unit is for desktop or wall mounting. The optionally available wall mounting frame (Part No. 7100.PGT120.WK) can be used to fix the unit to a wall.

The power is either supplied by a 9V battery or by a power supply. Insert the batteries by opening the battery compartment flap on the bottom side of the unit. Take care of the proper polarity. Close the battery compartment flap again.

It is strongly recommended to remove old or empty batteries to avoid battery leakage.

For heavy use or footwear in series mode, we recommend using the external power supply. Use only an original power supply connected to the "AC12V" socket on the rear. On plugging in external power, the internal battery is disconnected.

The battery should be removed to avoid wear out.

Do not connect any conducting articles with PGT 120 exept original accessories (power supply, battery and foot wear electrode) and the door opener.

Connect the foot electrode with the coloured marked plugs to the back of the unit for footwear test.

4 Operation

This tester has no power switch. Pressing an electrode or activating "footwear in series" activates the electrical circuit.

The measuring voltage is preset to 100V. Use the DIP switches 6+7 to adjust the voltage to either 30V or 50V.

4.1

Wrist strap test

Put on the wrist strap and connect it via a coil cord to the snap or to the socket on the left side of the unit.

Press the left electrode and keep it pressed. A peep signal indicates the start of measurement. After a short measuring time the result is displayed.

Release the electrode.

4.2

Coil cord test

To check only the coil cord, connect the coil cord to the 3mm snap located inside the wrist strap symbol and to the 10mm snap or socket on the left side of the unit. Press the left electrode and keep it pressed. A peep signal indicates the start of the measurement. After a short measuring time the result is displayed.

Release the electrode.

4.3

Footwear test (single shoe)

Stand on the foot electrode, then press the right electrode and keep it pressed. A peep signal indicates the start of measurement. After a short measuring time the result is displayed.

Release the electrode.

4.4

Wrist strap and footwear test

Put on the wrist strap and connect it via a coil cord to the snap or socket on the left side of the unit.

Stand on the foot electrode, then press one electrode and keep it pressed. A peep signal indicates the start of measurement. After a short measuring time the result is displayed.

Release the electrode.

The OK signal only appears when all measured values are within the limits.

4.5

Footwear in series

To show that "Footwear in series" is activated the red LED's for Hi-Fail of Footwear flash for a short time every 2s, while disspative shoes are not detected.

The footwear test can be accomplished hands free, without touching a electrode. This is useful in combination with passenger handling gates. The resistance is measured between the two shoes. This mode cannot directly indicate the faulty shoe. Press the Shoe electrode on the instrument to identify it.

Stand with both feet onto the foot electrode. If the shoes are dissipative the measurement starts automatically. After a short measuring time the result is displayed and the connected gate will open.

You can step of the foot electrode.

Even if footwear in series is active, you can perform a test according chapter 4.1 to chapter 4.4 by pressing a electrode, for example to identify a bad shoe.

5 Configuration

The unit can be configured with the DIP switches on the rear according to the table below.

Standard settings are marked bold.

6 Connectors

The connectors for the power supply, the foot electrodeand the door opener are located on the rear side of the unit. Use a "RJ12" western modular plug to connect the dry contact of the door opener.

The door opener relay is triggered and stays on for 3 seconds when the test result indicates OK.
