5.5 Temperature gauge
The temperature gauge (Fig. 7) is supplied to indicate the dielectric fluid temperature in degrees centigrade at
the top of the oil column. The gauge consists of two needles (one white and one red). The white needle is the
current oil temperature of the unit.
The red needle is a resettable maximum indicator. As the temperature of the oil rises, the white needle
pushesthe red needle higher with it. If the temperature ofthe oildeclines the white needle follows and goes
downwith temperature,theredneedlehoweverremainsatthehighesttemperature reachedandactsas a
recordertoindicatethehighesttemperatureachievedbytheunit. Theredneedle(maximumindicator)can
be reset by turning the knob on the front of the gauge face.
The temperature gauge consists of a long thermocouple that extends into the tank inside a protective
thermocouple well. The isolation between the thermocouple and the dielectric fluid facilities the removal and
replacement of the gauge without draining down the dielectric fluid.
The temperature gauge can be equipped with either one or two SPDT alarm contacts for remote monitoring or
fan control. These alarm contacts are factory set but can be adjusted if desired.
To adjust the contacts,remove thefaceof the gauge. Look toward the center of the gauge fora small Allen
head set screw. Loosen this set screw and manually move the contacts (red indicators toward the outer edge
ofthedial)tothedesired temperaturesettings. Gently retightenthesetscrewand replacegaugeface.For
