Electrostatic Discharge (ESD)

Handling Procedure

Magnetrol electronic instruments are manufactured to the

highest quality standards. These instruments use electronic

components that may be damaged by static electricity

present in most work environments.

The following steps are recommended to reduce the risk of

component failure due to electrostatic discharge.

• Ship and store circuit boards in anti-static bags. If an anti-

static bag is not available, wrap the board in aluminum

foil. Do not place boards on foam packing materials.

• Use a grounding wrist strap when installing and removing

circuit boards. A grounded workstation is recommended.

• Handle circuit boards only by the edges. Do not touch

components or connector pins.

• Make sure that all electrical connections are completely

made and none are partial or floating. Ground all equip-

ment to a good, earth ground.

Preliminary Operational Check

After unpacking and before installation, perform the

following operational check on the unit in a non-

hazardous area:

1. Apply proper operating voltage to terminals L1 and L2/N.

Power supply ground should be connected to the green

ground screw in housing base.

2. Fill a suitable container with liquid.

3. Place transducer gap in the liquid. The relay output should

actuate.

4. Remove transducer from the liquid. The relay output

should de-actuate. In case of malfunction, consult

Section 3.1, Troubleshooting on page 8.

Caution: This unit contains CMOS electronics which may become

damaged by static electricity. Do not touch any semicon-

ductor devices unless you are properly grounded.
