Description
The instrument is for permanent grounding monitoring of persons with wrist straps.
During this the capacitive resistance to earth is measured.
The unit is mounted on the workplace. The grounding must be connected to the grounding point
of the table or table mat. Only use included power supply plug.
Limits can be changed by user very easy. It can be done by calibrated resistors or by a reference
wrist strap.
By doing it with calibrated resistors it is an easy and cheap calibration of the unit.
The version PGT 52 also includes a potential free relay contact. This can be select as “o.k”. or
“Alarm” Output by jumper.

Only PGT 52:
J M2 OFF (open) Relay Mode = Alarm (Relay turns on if not o.k.)
ON (closed) Relay Mode = o.k. (Relay turns on if o.k.)
J M3 OFF (open) delay time to turn on by Alarm mode 10 seconds
ON (closed) no delay time for relay

Function
ABS Plastic housing with connector for one wrist strap (WST) with 10mm popper
Permanent grounding monitoring, which means the unit recognizes whether the wrist strap
is applied. The result is shown by two LED´s
green LED : flashes : WST in Park position
shines : WST applied and into the limits
red LED : flashes : WST resistor to low <
shines : WST resistor to high >
or WST wrong connect to the wrist
There is a buzzer also included for an acoustic signal delayed 10s after the red „Alarm“ LED
If the user leaf the working place he has to disconnect the cable at the wrist strap and place it on
the „PARK“ popper rat the unit.
The green LED will flash by 1Hz and there is no more monitoring

Relay Output (only PG -52)
The Relay function can be select by jumper J M2 ::
J M2 OFF (open)  Alarm relay Relay switchs on together with the buzzer (J M3=ON)
Otherwise (J M3=OFF) the relay switchs on 10seconds
delayed after the buzzer.
J M2 ON (closed)  „OK“ Relay Relay always switches on when green LED shines (o.k.)

5 Operating Instruction
Operating Instruction
WST – Cable in „PARK" Position WST – Cable connected to the wrist strap
Mount the unit with the power strips at the working place.
Connect the grounding cable to the reference grounding point at the table or table mat.
Connect a wrist strap cable to the „PARK“ position.
After connecting the power supply the unit switches into the stand by modus.
The „Park“ position is shown by flashing the green LED o.k. with app. 1Hz.
If the cable is disconnected from the „Park“ position the measure starts after 10 seconds.
Now it will be permanent measured whether the grounding is into the select limits.
The instrument really measures the capacitive resistor but is calibrated by a ohmic resistor
the actually limit can´t be definite exactly. But we have a reproducible measure.
Is the measure result into the limits the green LED will shine.
(PGT 52) by „OK“ – Relay Mode (JUM2 ON) the Relay switchs on together with the green LED !
If the measure result is out of the limits the green LED switch off and the red LED define it like:
Flash frequency ~1Hz : WST resistor to low <
shines : WST resistor to high > or WST wrong connect
Additional to the red LED the buzzer sounds after 10 seconds.
(PGT 52) Relay By „ALARM“ – Relay Mode (JUM2 OFF) the relay switch on together with the
buzzer:
by JUM3 OFF  10 seconds delayed
by JUM3 ON  directly
There is permanent measure as long as the WST is not connecting to the „Park“ position.

Calibration
Since the values are written directly with the adjustment into the EEPROM, the adjustment
of the limits with calibrated resistors is also simultaneously the calibration of the appliance.
In order to return to the norms, the calibrated resistors can be calibrated by the
manufacturer annually.
With these calibrated resistors, all appliances of the customer can then be recalibrated.
Please notice: The ohmic resistor only simulate the capacitive attenuation of a person
wearing the wrist strap.
Suggested calibration cycles:
annual
Guarantee Items
We provide a 24 month guarantee in case of proper application according to the manual.
Excluded of the guarantee are:
Damage by electric shock, wrong grounding and mechanical damage of the device.
The guarantee expires if the device was opened.
Different Versions:
PGT 51 – PGT 52 with 10mm Popper for the Park position
PGT 51/3 – PGT 52/3 3,5mm Popper for the Park position
