Dear Customer,
The PGTI20 is an electronic test apparatus for checking personnel
grounding systems such as electrostatic wrist straps and conductive
footwear.
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.
The positive testing of one or both grounding systems can be selected via
the DIP switch.
When used in combination with a turnstile or a similar singularization sys-
tem without activating the measuring plate, the footwear test can be made
by way of a series circuit from the left shoe to the right shoe via the body
(hands-free mode).
The test result is signalled optically, audibly (in the event of errors) and via
a floating relay contact.
The tests can be made in any order.
Please read these instructions carefully before starting the unit. This will
help you prevent personal injuries and damage to property.
Simply give us a call if you have any suggestions, proposals or ideas for
improvements. We greatly appreciate the feedback from the users of our
appliances.

3. Installation and assembly
The PTG120 tester has been designed for table and wall mounting. When
used as wall-mounted unit, use our wall bracket which is available as
optional accessory. Mount the wall bracket roughly at chest height to the
wall and attach the PGT120 with the self-adhesive connectors supplied
with the wall bracket.
3.1 Wall mounting plate for the PGT120
Mount the bracket with the plugs and screws supplied at chest height such
that the lower edge has the larger distance from the wall. Stick the self-
adhesive connectors to the wall bracket as shown in the outline drawing.
1 The surface of the plate and the bottom side of the PGT120 have to be
clean, dry and free of grease.
2 Remove protecting foil of the velcro tape pieces and do not touch the
sticky side.
3 Apply the velcro tape pieces according to the picture onto the mount-
ing plate.
4 Remove the second protecting foil of the velcro tape pieces and press
the PGT120 to those pieces. The back edge of the PGT120 needs to
be in line with the upper edge of the mounting plate.
5 After 24 hour curing time the PGT120 can be removed from the wall
mounting plate.
Removing:
Before removing the unit, please remove all plugs on the back of the
PGT120. Hold the unit on the left and the right and tip it forwards. To put
the unit back onto the mounting plate just press the unit back to the velcro
tapes.

3.2 Power supply
The unit can be operated by the external power supply or by a 9 V battery.
Battery change see chap. 5 Maintenance.
When testing frequently or when using the unit in the "shoes as series cir-
cuit" mode, it is advisable to supply the tester via mains power. Use only
the plug-type power supply included. Connect at the rear socket marked
"AC 12 V". Any battery connected will be automatically disabled as soon
as the jack is plugged in.
Caution!
Please remove the battery when the instrument is not battery operated for
a long period of time.
Warning!
The power supply must not be connected to ground.
3.3 Connections
The connections for cable cords are at the front of the unit.
The connections for power supply, footwear electrode and door opener
are at the rear of the unit.
The resistance of the test person and of the grounding system is tested
when checking the personnel grounding system.
The test person is contacted by operating the measuring plate or by step-
ping on the footwear electrode.

4.5 Testing wrist straps and footwear at the same time
DIP switch 1 + 2 at the rear of the unit is set to the AND function.
Put on the wrist strap and connect it via the coil cord to the snap or the
plug (5d, fig. 2) on the left hand side of the unit.
Connect the footwear electrode to the sockets with the shoe symbol
(4, fig. 1) at the rear of the unit.
DIP switch 3 at the rear of the unit is preset to the upper limit of 70 MOhm
(can be adjusted to 35 MOhm).
Stand with both shoes on the footwear electrode while pressing one
measuring plate and keep it pressed. An audible signal indicates that the
tester is switched on. After a short measuring time the test result will be
indicated by a LED:
Warning!
The green LED only flases when the resistance footwear and the
resistance wrist strap are between the limits.
If the wrist strap or the footwear are out of range, the fault will be indicated
by audible and visual (red LED) signals.
Evaluation of the signal identical to the separate tests.
The tester will be switched off when the measuring plate is released.
Green LED "OK" blinking: The resistance of both shoes is in the range of
100 kOhm to 70 MOhm (35 MOhm) and the
resistance wrist strap is in the range of
750 kOhm to 35 MOhm. If the lower limit is
switched off, the lower limit starts at 0 Ohm.

4.6 Footwear test as series circuit (hands-free mode)
Connect the enclosed footwear electrode to the sockets showing the shoe
symbol (4, Fig. 1) at the rear of the unit.
DIP switch 6 at the rear of the unit set in the mode "ON footwear test in
series enabled". The upper limit cannot be switched over.
The footwear test can be made without activating the measuring plate,
e.g. in combination with a turnstile or a similar singularization system.
Resistance is measured between left and right shoe.
Stand on the footwear electrode with both shoes. If the shoes are conduc-
tive, an audible signal will indicate that the tester is switched on. The test
result will be displayed on one of the LEDs after a brief measurement
period.
No individual error measurements will be displayed in this operating
mode. The defective shoe can be identified by pressing the measuring
plate again. The upper limit for each shoe is set for 70 MOhm.
The tester will be switched off when stepping off the footwear electrode.
Green LED "OK" flashes: The sum of resistance of both shoes is within
the range 200 kOhm to 140 MOhm, or 0 to
140 MOhm with the lower limit switched off.
Red LED "Hi-Fail" flashes:
audible signal The resistance of the series circuit exceeds the upper limit 140 MOhm.
Red LED "Lo-Fail" flashes:
audible signal The resistance of the series circuit falls below the lower limit 200 kOhm
(not applicable if the lower limit is switched off).
