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).

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
MIC 1462 Manual

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

2.4 Input Connections
In general, all wiring connections are made to the instrument after it is installed. Avoid electrical shock. AC power wiring must not be connected to
the source distribution panel until all wiring connection procedures are
completed.
Caution: This equipment is designed for installation in an
enclosure which provide adequate protection against electric shock. Local regulations regarding electrical installation should be rigidly observed. Consideration should be
given to prevention of access to the power terminations by
unauthorized personnel. Power should be connected via a
two pole isolating switch (preferably situated near the
equipment) and a 1 A fuse, as shown in Figure 2-7.
FIGURE 2-7
Main Supply
The instrument will operate on 90-264V AC 50/60 Hz mains (line) supply.
The power consumption is approximately 4 VA. If the instrument has relay
outputs in which the contacts are to carry mains (line) voltage, it is recommended that the relay contact mains (line) supply should be switched and
fused in a similar manner but should be separate from the instrument
mains (line) supply.

Remote Program Outputs (optional)
If the Remote Program Control Inputs has been specified, make connections as shown. These inputs can be either TTL or switch contact, selectable in Hardware Definition. The following applies:
Terminals 31 (R2) to 33 (RO) provide a binary-coded input which is used to
select the program:
Digital Inputs=TTL Level Digital Inputs=Contacts (switches)
R0 R1 R2 Progran Select R0 R1 R2 Program Select

For the Program Control Inputs, the following convention has been
adopted: for TTL inputs OFF=logic 0, ON=logic 1; for contacts (switch)
inputs OFFG=open, ON=closed.
Terminal 30 is the Program Abort control. It is EDGE SENSITIVE; an OFFON transition at any time will cause an immediate Program Abort.
Terminal 29 provides the Remote Run/Hold Program control and has an
identical effect to that of the Run/Hold key on the front panel. An OFF-ON
transition will cause the currently selected program to be run (or to be resumed if it is currently held); AN ON-OFF transition will cause the currently
running program to be held. Powering up the instrument with this terminal
ON will not cause a program to run.
Terminal 28 provides the "x60" program time base selection. This terminal
is LEVEL SENSITIVE (ON=minutes/seconds, OFF=hours/minutes). When
the instrument is powered up, the initially powered time bese will be according to the level on this terminal at power-up.
NOTE: All remote selection/control functions except the Abort function have

precedence over the corresponding front panel controls. The "x60" func-
tion will also take precedence over any present x60 parameter settings.

Section 3 - Operation
3.1 POWER UP PROCEDURE
Verify all electrical connections have been properly made before applying
power to the instrument.
If the instrument is being powered for the first time, it may be desirable to
disconnect the controller output connections. The instrument will be into
control following the power up sequence and the output(s) may turn ON .
During Power up, a self-test procedure is initiated during which all LED
segments in the two front panel displays appear and all LED indicators are
ON . When the self-test procedure is complete, the instrument reverts to
normal operation.
Note: When power is first applied, a delay of approx. 3 seconds will be
seen before the displays light up.

3.9 BASE MODE AND OFF MODE OUTPUTS
The Base Mode allows for the process and event outputs to be turned on or
off. When all outputs are off, the Base Mode becomes Off Mode. In Base
Mode the process output is adjusted by the controller based on the process
input and setpoint. The event outputs for the Base Mode are set in the
Configuration Mode. To view the present status of the outputs, press the
SCROLL key until OUTPUTS is displayed in the message display. Use the
UP and DOWN keys to turn the outputs ON or OFF (toggle between Base
Mode and Off Mode).
3.10 VIEWING THE TIME AND DAY
If the real time clock option is fitted, the operator may view the present time
and day. Press the SCROLL key until HH:MM Tim is displayed. This is the
present time of day in hours and minutes. Press the SCROLL key again
and Day: XXX is displayed with XXX being an abbreviation for the present
day of the week. If TIME BAD is displayed, the time and day must be set
in the Profile Mode (see sec. 6)
3.11 MANUAL CONTROL
In any mode except Configuration Mode, the operator may select manual
control of the process by simultaneously pressing the SCROLL and MODE
keys, provided Manual Mode is enabled in Controller Define Mode. The
instrument will then enter Base Mode or (if a program is currently running)
Program Run Mode with the program held. The Message Display will
show:
The lower Main Display will show the power output value, which may then
be adjusted using the UP and DOWN keys and the MAN indicator will be lit.
While manual control is being used, the power output display is included in
the displays available in Base Mode and Program Run Mode.
29 MIC 1462 ManualEdition 1
To cancel manual control, press the SCROLL and MODE keys simultaneously, wereupon the power out value display and the Power message
display will disappear and the Setpoint Controller will remain in whatever
mode prevailed when manual control was cancelled (if this is Program Run
Mode, the currently-running program will be resumed from the point at
which it was held).
3.12 USING THE PRE-TUNE FACILITY
The Pre-Tune facility is used to set the instrument's PID control parameters
to values which are approximately correct in order to provide a base from
which the Self-Tune facility may subsequently optimize tuning. Pre-Tune
may be activated as follows:
1. With the instrument in Base mode (with the RUN and HLD indicators
OFF), press the MODE key until the Message Display shows:
and the lower Main Display shows:
2. Press the UP key to change the lower Main Display to:
indicating that the Pre-Tune facility is now activated. The AT indicator
will flash.
NOTES:
1. If the process variable is within 5% of the input span from the
setpoint, the Pre-Tune facility cannot be activated and any attempt
to do so will have no effect.
2. Since the Pre-Tune facility is a single-shot operation, it will automatically de-activate itself once the operation is complete.

Base Mode), press the MODE key to obtain the same Message Displays
above; then press the DOWN key simultaneously to change the lower
Main display from ON to OFF.
3.13 USING THE SELF-TUNE FACILITY
The Self-Tune facility is used to optimize tuning while the Controller part of
the instrument is operating. Self Tune may be activated as follows:
1. With the instrument in Base Mode (with RUN and HLD indicators
OFF), press the MODE key until the Message Display shows:
and the lower Main Display shows:
2. Press the UP key to change the lower Main Display to:
indicating that the Self-Tune facility is now activated. The AT indicator is
on continuously.

show:
The user may then step through the Configuration Mode parameters using
the SCROLL key. For each parameter, the Message Display will show a
legend identifying that parameter and the lower main display will show the
current setting of that parameter. The setting may be adjusted using the
UP/DOWN keys. As soon as the setting is changed, the lower main display
will flash, indicating that the new setting has yet to be confirmed. When the
setting is as required, it may be confirmed by pressing the MODE key,
whereupon the upper display will stop flashing.
NOTE: Changes to certain Configuration Mode parameters (i.e.
input range, output use and type) will cause other mode parameters to be automatically set to their defauly values. Items affect
include Tune Mode, and Pretune and Auto Tune Facilities. Until the
Tune Mode setting have been verified by changing at least one
paraneter, the upper main display will show decimal points to indicate that the values are in their default condition.
Changes to Configuration Mode parameters will not be accepted
until they have been verified with the PROF key.

The displayed code may be incremented/decremented using the UP/
DOWN keys as required. The maximum setting available for this code is
4777. For example, the code for a thermocouple input, 4-20mA DC primary
output (Output 1) and relay Output 3 would be 2701. When the code is first
altered, the code display will flash, until the desired value is displayed and
confirmed by pressing the MODE key.
NOTE: It is essential that this code is changed promptly whenever
there is a change to the instrument's hardware configuration
(change of input/output type, alarm/recorder output added/removed
etc.). The instrument software depends upon this code to operate
correctly.
Hardware Definitions may be viewed as Read Only displays in Base Mode
by pressing the SCROLL and DOWN keys simultaneously.

Notes on Configuration Mode Parameters
1. If the secondary output is chosen as Output 2 (COOL) control output, its
action is always the compliment of the action of Output 1.
2. The default setting for Output 2 Usage is Alarm 2 hardware output,
direct-acting (if relay/SSR output) or Output 2 - COOL (if DC output).
3. The default setting for Output 3 Usage is Alarm 1 hardware output,
direct-acting (if relay/SSR output) or Process Variable Recorder Output
(if DC output)
4. This parameter does not appear in the sequence if the input type
selected is not thermocouple. If the CJC is disabled, the initial display in
Operator Mode will show horizontal bars flashing in the lower display.
5. The primary input default setting is dependent upon the hardware fitted,
as indicated in the Hardware Definition Code.
6. These parameters do not appear if the Hardware Definition Comms
parameters is set to nonE.
7. This parameter does not appear if the Programmer communications
option is set to operate in Master mode.
8. Internal software prevents (a) the Setpoint High Limit being given a
value less than any setpoint value contained in currently-resident pro grams, and (b) the Setpoint Low Limit being given a value greater than
any setpoint value contained in currently-resident programs.
9. These parameters are applicable only if a linear input is fitted.
10. These parameters do not appear if features are not fitted.
11. When X60 in Profile Set = OFF, Time = hours/minutes and
