Installation and Wiring 2.1

Electrical code requirements and safety standards should be observed and
installation performed by qualified personnel.

The electronic components of the instrument may be removed from the
housing during installation. To remove the components, grip the side
edges of the front panel and pull the instrument forward. During re-installa­tion, the vertically mounted circuit boards should be properly aligned in the
housing.

Ensure that the instrument is correctly orientated. A stop will operate if an
attempt is made to insert the instrument incorrectly.

can be over-ridden with enough force. If in doubt, check orientation
again!

Recommended panel opening sizes are illustrated in Figure 2-1, page 8.
After the opening is properly cut, insert the instrument into the panel open­ing. Ensure that the panel gasket is not distorted and that the instrument is
positioned squarely against the panel. Slide the mounting clamp into place
on the instrument (see Figure 2-3, page 9) and push it forward until it is
firmly in contact with the rear face of the mounting panel.

CAUTION: This stop

Note: The mounting clamp tongues may engage either on the
sides or the top/bottom of the instrument housing. Therefore, when
installing several instruments side-by-side in one cut out, use the
ratchets on the top/bottom faces.

Preparation for Wiring 2.2

2.2.1 WIRING GUIDELINES

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.

2.2.1.1 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

9 MIC 1161 Manual

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.

2.2.1.2 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.

2.2.1.3 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

• AC power
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 the wires. If wires must cross each other, do so at
90 degrees. This will minimize the contact with each other and reduces
“cross talk”.

MIC 1161 Manual

10

“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 its source.

2.2.1.4 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.

2.2.1.5 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, page 12. 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.

2.2.2 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 condi-

tions, 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

THERMOCOUPLE LEAD RESISTANCE

Thermocouple lead length can affect instrument accuracy since the size
(gauge) and the length of the wire affect lead resistance.

To determine the temperature error resulting from the lead length resis­tance, use the following equation:

Terr = TLe * L where; TLe = value from appropriate table

L = length of leadwire in thousands of feet

Example:
A instrument is to be located in a control room 660 feet away from the pro­cess. Using 16 AWG, type J thermocouple, how much error is induced?

Terr = TLe * L

TLe = 2.47 (°F per 1000 ft) from Table 2
Terr = 2.47 (°F/1000 ft) * 660 ft
Terr = 1.6°F

RTD LEAD RESISTANCE

RTD lead length can affect instrument accuracy, since the size (gauge) and
length of the wire affect lead resistance.

To determine the temperature error resulting from the lead length resis­tance, use the following equation:

Terr = TLe * L where; TLe = value from Table 3 if 3 wire RTD or

Table 4 if 2 wire RTD

L = length of lead wire in thousands of feet

During the condition when the annunciator output is active, the EXCEED
indicator will be flashing.

If the Reset key is pressed while the limit is exceeded, the EXCEED indica­tor will change to ON steady and the annunciator output is inactive. Subse­quently, when the limit is not exceeded, the EXCEED indicator will go off.

3.1.9 REMOTE RESET (optional)

The Remote Reset option allows a dry contact closure to substitute for the
front panel Reset switch. Operation is as follows:

If the option "rrES" (remote reset) is selected then:

A contact closure will simulate the action of the front panel reset

switch.

A contact opening will have no effect.
If the external contacts are left closed, only ONE reset operation will occur.

If the instrument subsequently goes into a state where reset is required
again, the contacts must be opened and closed again. The front panel
Reset switch can still be used to action a reset if required.

Configuration 3.2

All configurable parameters are provided in Tables 3-1 through 3-3 on the
following pages. These tables illustrate the display sequence, parameter
adjustment and factory setting for each step.

Depression of the SCROLL key will cycle the display (if alarms are not
active) to the "Loc" feature where, after entering the correct code, the dis­play cycles through all enabled modes as follows:

MIC 1161 Manual

CONTROL ---- PROGRAM ---- SETUP
(Ctrl) (Prog) (SEt)

If a mode is not enabled it will be skipped over by the routine.

3.2.1 ENABLE MODE

The Enable mode provides a means of enabling or disabling access to the
Program and Set-Up modes. Also found in the Enable mode is the current
code value for the LOC/ULOC feature. The code may be modified here by
using the UP/DOWN keys when the code is displayed.

If a mode has been disabled, then that mode will not be displayed or avail­able to the user in the Control mode. See Table 3-1 (below) for the Enable
mode procedure.

3.2.2 PROGRAM MODE

The Program mode is used to configure or re-configure the instrument.
The input and output selections are made in the Program mode. All pos­sible parameters are illustrated in Table 3-2 (page 28). Only those param­eters that are applicable to the hardware options chosen will be displayed.

3.2.3 SET-UP MODE

The Set-Up mode is used to adjust the setpoint, make alarm settings and
retransmit scaling needed for proper operation of the instrument. See
Table 3-3 (page 30) for the Set-Up mode. Only those parameters that are
applicable will be displayed.

Glossary of Terms

Input Filter Time Constant

This parameter is used to filter out any extraneous impulses on the process
variable. This filtered PV is used for all PV-dependent functions (limit,
alarm, etc). The time constant is adjustable from 0.0 seconds (off) to 100.0
seconds, in 0.5 second increments. Default value is 2.0 seconds. Display
code is FiLt.

Hysteresis

This parameter is a switching differential on the non-exceeded side of limit
and is adjustable within the range of 0 to 10.0%, expressed in units. De­fault value is 1. Display code is HySt.

Process Output Upper Value

This parameter defines the value of the retransmitted output (process vari­able or setpoint , whichever is applicable) at its maximum value; for ex­ample, for a 0-5V output, this value corresponds to 5V. It may be adjusted
within the range -1999 to 9999. The decimal position is always the same
as that for the process variable input. Default value is Input Range Maxi­mum. Display code is Pou.

Note: If this parameter is set to a value less than that for the Process Out­put Lower Value, the relationship between the process variable/setpoint
value and the retransmission output is reversed.

Process Output Lower Value

This parameter defines the value of the retransmitted output (process vari­able or setpoint, whichever is applicable) at its minimum value; for ex­ample, for a 0-5V output, this value corresponds to 0 V. It may be adjusted
within the range -1999 to 9999. The decimal position is always the same
as that for the process variable input. Default value is Input Range Mini­mum. Display code is PoL.

Note: If this parameter is set to a value greater than that for the Process
Output Upper Value, the relationship between the process variable/setpoint
value and the retransmission output is reversed.

MIC 1161 Manual

Appendix C
Hardware Definition Code

The Hardware Definition Code is used to represent the hardware installed
(input type, Output 2 type, Output 3 type and Options); this must be com­patible with the hardware actually installed. It can be accessed, with the
instrument in Program mode, by simultaneously depressing the DOWN and
SCROLL keys while the parameter is displayed in the lower display and the
value in the upper display. The displays will show "XXXX" (where X repre­sents any number) in the upper display and "dEFn" in the lower display,
where:

the first (left-most) digit is input type:

1=RTD/Linear mV
2=Thermocouple
3=Linear DC mA
4=Linear DC V

the second digit is Output 1 type:

1=Relay (Limit Only)

the third digit is Output 2 type:

0=Output 2 not installed
1=Relay (Alarm Only)

the fourth digit is Output 3 type:

0=Output 3 not installed
1=Relay (Alarm only)
3=DC 0-10V (retransmit only)
4=DC 0-20mA (retransmit only)
5=DC 0-5V (retransmit only)
7=DC 4-20mA (retransmit only)

The displayed code may be incremented/decremented using the UP/
DOWN keys as required. The maximum setting available is 4117. For
example, the code for a thermocouple input, Relay Output 1 and Relay
Output 3 would be 2101. When the code is first altered, the code display
will flash, until the desired value is displayed and confirmed by pressing the
RESET key.

39 MIC 1161 Manual

While the Hardware Definition Code is displayed, depressing the SCROLL
key will cause the display to change to:

nonE or r485 or rrES

OPtn OPtn OPtn
Where "nonE" indicates the absence of the communications option and the

remote reset option. "r485" indicates the presence of the communications
option. "rrES" indicates the presence of the remote reset option.

NOTE: It is essential that this code is changed whenever there is a change
to the instrument's hardware configuration (change of input type, alarm/
retransmit output etc.). The instrument's software depends upon this code
to ensure that the instrument operates correctly.

To exit from the Hardware Definition Code display, depress the DOWN and
SCROLL keys simultaneously.
