BJZ Industriedienst und Vertrieb, D-75031 Eppingen, Tel: 07262/1064 Fax: 07262/1063 Operating manual WRIST STRAP MONITOR

03/07 - am.doc

Order numbers: C-193 2334 (4,5 mm press stud), C-193 2331(10,3 mm press stud)

The system consists of two parts: monitor and adapter

Mounting and wiring

A 9 V adapter with fixed voltage and a 3,5 mm stereo jack serves as power

supply (external positive pole).

Connect the stereo jack with the monitor and plug the adapter into the power

socket.

It is recommendable to mount the monitor at eye level right above the

workstation by using, for example, Velcro.

The black ground conductor of the monitor must be connected to the protective

conductor of a second power socket by using, for example, a BJZ grounding

box.

Finally, the wrist strap is attached to the monitor.

Function

Place the switch in direction of the word "Aktiv". If the wrist strap is applied

correctly, the "Safe" - LED will be illuminated.

If the red "Fault" - LED is flashing and a warning signal can be heard, this may

have the following reasons:

• the wrist strap has been removed

• there is no connection between the ground and the monitor

• the wrist strap is damaged

• the coil cord is damaged

Identify the reason of the alert and fix the problem.

If the person connected to the monitor wants to leave the workstation, the switch

must be placed in direction of the word "Stand by". In this case the warning

signal is not actuated, but the flashing "Fault" - LED reminds the person to put

on the wrist strap again.

Approach in case of failure

Check the wiring and wrist strap for functional capability. If necessary calibrate

the monitor.

Calibration

1. Necessary tools:

- defined resistance (e.g. resistance box), junction cord

2. Setup

The setup of the components must be arranged like in the following drawing:

Power supply

adapter 9V

Resistance box

Connection to

round

Connection for press stud

grounding cord

Borehole for adjustment

Adjustment

When using grounding cords with 1 x 10 6

Ω protective resistance, the resistance

box should be regulated to 3 x 106 .Ω

When using grounding cords with other protective resistance, the resistance box

should be regulated to + 2 x 106 .Ω

Connect the monitor to the power supply and place the switch in direction of

"Aktiv". By means of a screw driver the potentiometer can be reached through

the borehole saying "Adj." Adjust the potentiometer until the LED switches from

red to green, when using the appropriate resistance. If necessary, the borehole

can be sealed after adjustment.
