4.3 TROUBLE SHOOTING

!!  CAUTION:

The electronics are not protected against condensed

liquid water inside the enclosure.  If conduit is used, be sure conduit is dry
or sealed at the instrument to prevent conduit condensation from entering
the enclosure.

TABLE I.  TROUBLE SHOOTING GUIDE

OBSERVATION

PROBABLE CAUSE

REMEDY

Flow trip level continually
drifting downward with constant
flow.

1. Coating forming on

wetted surface of
transducer.

1. Clean transducer

periodically.

2. Adjust trip potentiometer

clockwise until layer
build-up stabilizes.

After switch has been operating
properly: relay trips with flow
above trip level and cannot be
adjusted using SECTION 2.4
instructions.  Relay does not trip
when flow falls below trip level
and cannot be adjusted using
SECTION 2.4 instructions.

1. Bad electronic

component.

1. Contact factory.

Relay cannot be made to trip by
adjusting "Trip" potentiometer.

1. Initial flow rate estimate

was too low or too high.

2. Flow media change.

1. Check flow conditions.
2. Contact factory.

LED is not lit and relay stays in
alarm condition (N.C. contact is
made).

1. No power to electronics.
2. Blown fuse.

1. Check incoming power.
2. Replace fuse with ¼

Amp fast acting fuse
(fuse is in PWB socket).

3. Contact factory.
