MOUNTING

When mounting the instrument, it is important the
instrument remains within the ambient temperature
range of 10 to 125°F. Mounting it in any position is
permissible. After inserting the instrument into the
panel, secure it with the mounting bracket provided with
each unit.

• Both solderless terminals or “stripped” leads

can be used for power leads. Only “stripped” leads
should be used for thermocouple connections to
prevent compensation and resistance errors.

• Take care not to over-tighten the terminal screws.

• Unused control terminals should not be used as

jumper points as they may be internally connected,
causing damage to the unit. This indicator is not
to be used in hazardous locations as defined in
Article 500 of the National Electric Code.

TROUBLE SHOOTING

Experience has proven that many control problems are
not caused by a defective instrument. See list below
for some of the common causes of failures:

Line wires are improperly connected.
No voltage between line terminals.
Incorrect voltage between line terminals.
Connection to terminals are open, missing or loose.
Thermocouple or RTD is open at tip.
Thermocouple or RTD lead is broken.
Shorted thermocouple or RTD leads.
Short across terminals.
Burned out line fuses.

Defective line switches.
Defective circuit breakers.

If these points have been checked and the indicator still
does not function, it is suggested that the instrument be
returned to the factory for inspection.

Do not attempt to make repairs. It usually creates
costly damage. Also, it is advisable to use adequate
packing materials to prevent damage in shipment.

CALIBRATION INSTRUCTIONS

W

ARNING–HIGH VOLTAGE PRESENT!

The indicator should be allowed to warm-up for 1/2 hour
before accurately checking calibration.

Remove the front faceplate by twisting a flat screwdriv­er in the slot under the front-center area of the face­plate.

Calibration is accomplished by using the two poten­tiometers located on the right-hand side of the bottom
PC board. The potentiometer to the right is the zero
adjustment. The potentiometer to the left is the span
adjustment. The two potentiometers have a slight effect
on each other, so calibrate low-scale and high-scale at
least three times.
