Options
The following paragraphs describe the options
available with the ECT family of transmitters:
• EM–ExternallyMountedTransformer, for use
with the 0-5Aac input configuration, this option
consists of a toroidal transformer that physically
separates high-level current input from the
receiving device in a process loop. This provides
the added convenience of allowing the servicing
of receivers without having to interrupt process
signals.
• TX–TransmitterExcitation, available for use
with the 4-20mA input configuration, TX-equipped
ECTs provide power for a 2-wire transmitter in
the process loop, eliminating the need to provide
separate power supplies for the non-isolated
transmitters.

RF–RFI/EMIProtection, available for use with
•
our aluminum housings, this option provides
you with outstanding protection against RFI and
EMI interference. Units with the -RF option are
provided with 30V/m@20-1000MHZ protection
with less than ±0.1% of span error (requires -EM
option for AC current input)

Calibration
Prior to shipment, every ECT 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
company name.
Before placing your ECT into service, a bench check
of basic operation is recommended to ensure that the
unit hasn’t sustained any damage during transit, and to
set zero and span points for your application.
Every unit should be:
• CheckedtoverifythattheappropriateECT
model has been ordered for the intended
application.
• Connectedinacalibrationsetup(described
later in this section) and checked for desired
output.
• Adjustedfordesiredzeroandspan.
Calibration Setup
Table 3 lists the equipment you will need to bench
check the ECT. These materials are not supplied by
Moore Industries, but should be available in those
environments suited for calibration and maintenance of
electronic instruments.
Figures 2 through 5 show the calibration setups for
each type of ECT. Moore Industries recommends
that the procedures in this section be carried out
at a technician’s bench or in a similar, lab-type
environment. Do not calibrate the ECT in the field or
installed in the application.
Calibration Procedure
With the unit incorporated into the setup described in
the appropriate Figure (2, 3, 4 or 5):
1. Apply the appropriate power to the ECT.
2. Set the Voltage or Current Calibrator to 100%
span (full scale input) for the type of ECT being
calibrated. For example, 20mA for a
4-20mA input unit or 5V for a 1-5V input unit.

3. Adjust the Span potentiometer (pot) until
the multimeter reads 20mA, plus/minus the
stated accuracy specification. If measuring
the voltage drop across the precision resistor,
adjust the pot until output is 5V, plus/minus the
stated accuracy specification.
4. Set the Calibrator to 0% of the rated span for
the type of ECT being calibrated. For example,
4mA for a 4-20mA input unit or 1V for a 1-5V
input unit.
5. Adjust the Zero pot until the multimeter
reads 4mA, plus/minus the stated accuracy
specification. If measuring the voltage drop
across the precision resistor, adjust the
pot until output is 1V, plus/minus the stated
accuracy specification.
6. Repeat steps 2 through 5 for each channel
until the ECT output or the voltage across the
resistor is stable at both 0 and 100% of rated
input span.

Recommended Ground Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• AnyMooreIndustriesproductinametalcaseor
housing should be grounded.
• Theprotectiveearthconductormustbeconnected
to a system safety earth ground before making
other connections.
• Allinputsignalsto,andoutputsignalsfrom,
Moore Industries’ products should be wired using a
shielded, twisted pair wiring technique. Shields
should be connected to an earth or safety ground.
• Forthebestshielding,theshieldshouldberun
all the way from the signal source to the receiving
device. (see Note below)
CE Certification-related Guidelines
The grounding and wiring practices described above
must be followed in order for the unit(s) to meet the
requirements set forth in EMC standard EN61326.
The Low Voltage Directive also applies to AC powered
and high voltage input versions of the ECT. In order
to comply with EN61010-1 (Low Voltage Directive) all
guidelines in this section must be followed.
• The maximum length of unshielded input and
output signal wiring should be 2 inches.
Note:
Some of Moore Industries’ instruments can be
classified as receivers (IPT 2, IPX 2, etc.) and some
can be classified as transmitters (TRX, TRY, etc.)
while some are both a receiver and a transmitter
(SPA 2, HIM, etc). Hence, your shield ground
connections should be appropriate for the type
of signal line being shielded. The shield should
be grounded at the receiver and not at the signal
source.

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 give us a Purchase Order number 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.
