1 MIC 1462 ManualEdition 1

The Setpoint Programmer has numerous operating modes:

Base Mode: Day to day PID control operations with no program running.
In this mode, a program may be selected to run.

Profile Run Mode: A selected program is running, held or waiting for a
pre-defined delay before starting. In this mode, the operator can view
status and program information.

Profile Define Mode: Used to view/create/edit programs. this mode is
entered either from Base Mode (selected program may be edited/cre­ated) or from Program Run Mode (currently-running program may be
edited).

Controller Define Mode: Used to define the controller characteristics.

Tune: Used to adjust tuning parameters

Alarm: Used to define and set alarms

Enable: Provides a means of enabling or disabling access to setpoint
changes and each of the non-control modes.

2.1 UNPACKING PROCEDURE

1. Remove the instrument from its packing. The instrument is supplied
with a panel gasket and push-fit strap. Retain the packing for future use,
should it be necessary to transport the instrument to a different site or
return it to the factory for repair/testing.

2. Examine the delivered items for damage or deficiencies. If any is
found, notify the carrier immediately. Check that the model number
shown on the label affixed to the instrument housing corresponds to that
ordered (see Appendix D).

2.2 PANEL-MOUNTING THE SETPOINT PROGRAMMER

The panel on which the instrument is to be mounted must be rigid and may
be up to 6.0 mm (.25 inches ) thick. The cutout required for a single instru­ment is shown in Figure 2-1.

To panel-mount the instrument:

1. Insert the rear of the instrument housing through the cutout (from the
front of the mounting panel) and hold the instrument lightly in position
against the panel. Ensure that the panel gasket is not distorted and that
the instrument is positioned squarely against the mounting panel. Apply
pressure to the front panel bezel only.

Caution: Do not remove the panel gasket, as this may result
in inadequate clamping of the instrument in the panel.

2. Slide the fixing strap in place (Figure 2-3) and push it forward until it
is firmly in contact with the rear face of the mounting panel (the tongues
on the strap should have engaged in matching rachet positions on the
instrument housing and the fixing strap springs should be pushing firmly
against the mounting panel rear face).

Once the instrument is installed in its mounting panel, it may be subse­quently removed from its housing, if necessary, as described in Appendix B.

2.3 PREPARATION FOR WIRING

Electrical noise is a phenomenon typical of industrial environments. The
following are guidelines that must be followed to minimize the effect of noise
upon any instrumentation.

2.3.1 INSTALLATION CONSIDERATIONS

Listed below are some of the common sources of electrical noise in the
industrial environment:

• Ignition Transformers

• Arc Welders

• Mechanical contact relay(s)

• Solenoids

5 MIC 1462 ManualEdition 1

Before using any instrument near the device listed, the instructions below
should be followed:

1. If the instrument is to be mounted in the same panel as any of the
listed devices, separate them by the largest distance possible. For
maximum electrical noise reduction, the noise generating devices should
be mounted in a separate enclosure.

2. If possible, eliminate mechanical contact relay(s) and replace with
solid state relays. If a mechanical relay being powered by an instrument
output device cannot be replaced, a solid state relay can be used to
isolate the instrument.

3. A separate isolation transformer to feed only instrumentation should
be considered. The transformer can isolate the instrument from noise
found on the AC power input.

4. If the instrument is being installed on existing equipment, the wiring in
the area should be checked to insure that good wiring practices have
been followed.

2.3.2 AC POWER WIRING

Neutral (For 115 VAC)
It is good practice to assure that the AC neutral is at or near ground poten­tial. To verify this, a voltmeter check between neutral and ground should be
done. On the AC range, the reading should not be more than 50 millivolts.
If it is greater than this amount, the secondary of this AC transformer sup­plying the instrument should be checked by an electrician. A proper neutral
will help ensure maximum performance from the instrument.

2.3.3 WIRE ISOLATION

Four voltage levels of input and output wiring may be used with the unit:

• Analog input or output (i.e. thermocouple, RTD, VDC, mVDC, or
mADC)

• SPDT Relays

• SSR driver outputs

• AC power

Edition 1

The only wires that should run together are those of the same category. If
they need to be run parallel with any of the other lines, maintain a minimum
6 inch space between wires. If wires must cross each other, do so at 90
degrees. This will minimize the contact with each other and reduces "cross
talk". "Cross Talk" is due to the EMF (Electro Magnetic Flux) emitted by a
wire as current passes through it. This EMF can be picked up by other
wires running in the same bundle or conduit.

In applications where a High Voltage Transformer is used (i.e. ignition sys­tems) the secondary of the transformer should be isolated from all other
cables.

This instrument has been designed to operate in noisy environments, how­ever, in some cases even with proper wiring it may be necessary to sup­press the noise at the source.

2.3.4 USE OF SHIELDED CABLE

Shielded cable helps eliminate electrical noise being induced on the wires.
All analog signals should be run with shielded cable. Connection lead
length should be kept as short as possible, keeping the wires protected by
the shielding. The shield should be grounded at one end only. The pre­ferred grounding location is the sensor, transmitter, or transducer.

2.3.5 NOISE SUPPRESSION AT THE SOURCE

Usually when good wiring practices are followed no further noise protection
is necessary. Sometimes in severe electrical environments, the amount of
noise is so great that it has to be suppressed at the source. Many manu­facturers of relays, contactors, etc. supply "surge suppressors" which
mount on the noise source.

For those devices that do not have surge suppressors supplied. RC (resis­tance-capacitance) networks and/or MOV (metal oxide varistors) may be
added.

Inductive Coils - MOV's are recommended for transient suppression in
inductive coils connected in parallel and as close as possible to the coil.
See Figure 2-4. Additional protection may be provided by adding an RC
network across the MOV.

Contacts - Arcing may occur across contacts when the contact opens and
closes. This results in electrical noise as well as damage to the contacts.
Connecting a RC network properly sized can eliminate this arc.

For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 mi­crofarad capacitor (1000 volts) is recommended. For circuits from 3 to 5
amps, connect 2 of these in parallel. See Figure 2-5, below.

2.3.5 SENSOR PLACEMENT (THERMOCOUPLE OR RTD)

Two wire RTD's should be used only with lead lengths less than 10 feet.

If the temperature probe is to be subjected to corrosive or abrasive condi­tions, it should be protected by the appropriate thermowell. The probe
should be positioned to reflect true process temperature:

In liquid media - the most agitated area
In air - the best circulated area
