FCT [UB]

Calibration

Prior to shipment, every FCT [UB] is subjected to
rigorous testing by our team of skilled technicians.
Every product Moore Industries manufactures, sells
and services is guaranteed to meet the strict quality
standards that have become synonymous with our
name.

Before placing your FCT [UB] into service, a bench
check of basic operation is recommended to ensure
that the unit hasn’t sustained any damage during
transit.

Every unit should be:

• Checked to verify that the appropriate FCT [UB]
model has been ordered for the intended application.

• Connected in a calibration setup (described later in
this section) and checked for desired output.

• Adjusted for desired zero and span.

Even if a unit has been configured to your specifica­tions by the factory (factory calibration), it is a good
idea to perform this calibration as a simple bench
check. The procedures provide a safe means to
uncover any unit damage that may have occurred
during shipping, and offer a simple familiarization
with FCT [UB] operation in the safety of a testing
environment, separate from the intended process or
application.

These procedures should be carried out in an
environment considered appropriate for general
testing of electronic equipment, rather than in the
field. Use a technician’s bench or a similar, lab­type environment.

Setting Up for Zero/Span
Calibration

The equipment listed in Table 1 is needed when
calibrating the FCT [UB]. These items are not
supplied by Moore Industries, but should be
available in most testing labs.

Be sure to use calibrated test equipment when
performing the bench check and zero/span
adjustment of the FCT [UB]. The use of inaccurate
test equipment will result in unreliable settings and
precipitate costly process down-time.

Figure 1 shows the basic hookup used in the
calibration procedures. Use a screwdriver to loosen
terminal screws and connect appropriate leads to
the labeled terminals. With connections completed
as shown, apply the appropriate power to the setup
and allow a few minutes for stabilization/warm-up.

Calibrating Zero and Span

Before beginning this procedure, check the model
number of the unit to be calibrated for the appropri­ate input/output type and range, and the required
power input type.

The two pots on the front panel of the FCT [UB] are
labeled “ZERO” and “SPAN”. They are both 15-turn
potentiometers, equipped with slip clutch mecha­nisms to prevent damage in the event of
overturning.

When calibrating the FCT [UB] zero and span, turn
the appropriate pot clockwise to increase the
setting, and counterclockwise to decrease the
setting.

To Calibrate Zero and Span:

1. Turn both pots fully counterclockwise (minimum
zero and span, 15 turns), then approximately 7
turns clockwise. This approximates mid-scale
for the pots.

2. Set the input source in the setup to 0% (zero
percent). 1V, for example, if the FCT [UB] being
calibrated is rated for 1-5V input.

3. Note the meter reading, and turn zero pot
clockwise to raise 0% output, or
counterclockwise to lower 0% output, until the
correct level is achieved.

4. Set the input source to 100% (full scale). 5V, for
example, if the FCT [UB] being calibrated is
rated for 1-5V input.

The Interface Solution Experts

5. Note the meter reading, and turn span pot
clockwise to raise 100% output, or
counterclockwise to lower 100% output, until the
correct level is achieved.

6. Repeat steps 2 through 5 until output is stable at
both zero and 100 percent input.

Installation

S

Installation of the FCT [UB] is a two-step process.
First, the unit is mounted, and then the electrical
connections are made.

Before installing the FCT [UB], Moore Industries
suggests that the calibration procedures be carried
out to confirm that the configuration of the unit is
appropriate for the intended application. Costly
down-time will result if an inappropriately configured
unit is installed.

Electrical Connections

All electrical connections are made to terminals on
the front of the unit. Each terminal is labeled.
Refer to the Installation drawings for connections.

To make a connection, loosen the screw that
corresponds to the terminal, install #6 ring or spade
lug on all wires and tighten the screw until snug or 8
inch pounds maximum.

Recommended Ground Wiring
Practices

The following ground wiring practices must be followed
to ensure proper performance of the FCT [UB]:

• Any Moore Industries product in a metal case
or housing should be grounded.

• All signals to and from Moore Industries’
products should be wired using a shielded,
twisted pair technique. Shields are to be
connected to an earth or safety ground at the
unit.

• The maximum length of any unshielded input
and/or output signal wiring is 2 inches.

Operation

Once properly calibrated, connected, and powered,
the FCT [UB] will operate reliably for an extended
period of time. Unit maintenance is a simple check
of terminal connections every six months.
If an FCT [UB] begins to malfunction or to function
below rated specifications, complete the following
checklist before calling the factory for assistance.

• Verify that all electrical connections are clean
and tight.

• Verify that the power source for the unit is
supplying power at levels rated safe and
appropriate according to product
specifications.

• Check the calibration of the instruments used
in calibrating the FCT [UB].

• Verify that other devices in the process loop
are not the cause of the problem.

If the difficulties continue, remove the unit
from service and recalibrate.

RETURN PROCEDURES

To return equipment to Moore Industries for repair, follow these four steps:

1. Call Moore Industries and request a Returned Material Authorization (RMA) number.
Warranty Repair –

If you are unsure if your unit is still under warranty, we can use the unit’s serial number
to verify the warranty status for you over the phone. Be sure to include the RMA
number on all documentation.

Non-Warranty Repair –
If your unit is out of warranty , be prepared to giv e us a Purchase Order n umber when
you call. In most cases, we will be able to quote you the repair costs at that time.
The repair price you are quoted will be a “Not To Exceed” price, which means that the
actual repair costs may be less than the quote. Be sure to include the RMA number on
all documentation.

2. Provide us with the following documentation:

a ) A note listing the symptoms that indicate the unit needs repair
b ) Complete shipping information for return of the equipment after repair
c) The name and phone number of the person to contact if questions arise at the factory

3. Use sufficient packing material and carefully pack the equipment in a sturdy shipping

container.

4. Ship the equipment to the Moore Industries location nearest you.

The returned equipment will be inspected and tested at the factory. A Moore Industries
representative will contact the person designated on your documentation if more information is
needed. The repaired equipment, or its replacement, will be returned to you in accordance with
the shipping instructions furnished in your documentation.
