SECTION 1: PRODUCT DESCRIPTION
1.1 General
This instrument is a microprocessor based single loop controller capable of measuring
and displaying temperature, pressure, flow, and level from a variety of inputs. The
control is configurable to be either high-limit, low-limit, or both types.
Control functions, alarm settings and other parameters are easily entered through the
front keypad. E2 Technology (100 year life) protects against data loss during AC power
outages.
The input is user configurable to directly connect to either thermocouple, RTD, mVDC,
VDC or mADC inputs. The instrument can operate from either a 90-264 VAC, 50/60 HZ
power supply, or optional 24V AC/DC power supply.
1.2 Displays
Each instrument is provided with dual displays and status indicators as shown in Figure
1 -1. Typically, the upper display displays the value of the process variable, while the
lower display displays the setpoint value. Alternate displays can be selected in the
Setup Mode.
1.3 Alarms
Alarm indication is standard on all instruments. Up to two alarm outputs are optional.
Alarm type may be set as Process Direct or Reverse (high or low), Logical Combination
of the two alarms, Annunciator Direct or Reverse, High Limit, or Low Limit. Alarm
status is indicated by LED.

SECTION 2: INSTALLATION AND WIRING
2.1 General Information
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.
Recommended panel opening sizes are illustrated in Figure 2-1. 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 and push it forward until it is firmly in
contact with the rear face of the mounting panel.
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.

2.2 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 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
Before using any instrument near the device listed, the instructions below
should be followed:
5
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.
2.2.2 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.
2.2.3 Wire Isolation
Three 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". "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.
6
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.
2.2.4 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.
2.2.5 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 (resistancecapacitance) 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.
7
FIGURE 2-4
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 (1 000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of
these in parallel. See Figure 2-5.
FIGURE 2-5
8
2.3 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.

SECTION 3: OPERATION
3.1 Power Up Procedure
Verify all electrical connections have been properly made before applying power to the
instrument.
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 about 3 seconds will be seen before the
LEDs will light.

3.3 Displays
During configuration the upper display shows the parameter setting. The lower display
shows the parameter code (tag name) for the currently selected parameter. During
operation, the upper display shows the value of the process variable. The lower display
shows the setpoint value. The operation display can be altered by the Display
parameter in the Setup mode.
3.3.1 Alarm Status Display
The user may view the status of the instrument's alarm(s) by depressing the SCROLL
key until the lower display shows the legend "ALSt" and the upper display shows the
alarm status in the following format:
NOTE: This display is available only if one or more of the alarms is/are active.
3.3.2 Over-Range/Under-Range Display
If the process variable attains a value higher than the input scale maximum
limit, the upper display will show:
16
If the process variable attains a value lower than the input scale minimum, the upper
display will show:
If a break is detected in the sensor circuit, the upper display will show:
3.4 Front Panel Indicators
OUT Indicates the status of the Limit Relay. When the indicator is on, the relay is de-
energized, and when off, the relay is energized.
EXCEED This indicator is on when the process variable exceeds the limit setpoint
(above for high limit, below for low limit). The indicator flashes if the error is not
acknowledged (i.e. Reset key is not pressed). The indicator is on steady if the
error has been acknowledged (i.e. Reset key has been pressed). Note: This
LED action will occur even if the annunciator output is NOT selected in
configuration.
ALM This indicator shows an alarm condition.
S Indicates when in Set-Up mode.
3.5 Exceeding Limit Setpoint
If the process value exceeds the limit setpoint, the limit relay will change state and
latch. This is noted by the OUT indicator. The EXCEED indicator will also flash.
To acknowledge the limit condition, press the RESET key. If the process value
exceeds the limit setpoint, the EXCEED indicator will change to a steady on condition.
The EXCEED indicator will turn off once the process value no longer exceeds the limit
setpoint.
In order to reset the limit relay, the process value must not exceed the limit setpoint.
Pressing the RESET key with the control in this state will reset the limit relay, and the
OUT indicator will turn off.
17
NOTE: The hysteresis limit value in the setup mode affects the value at which the
control will reset. In the event of a high limit condition, the high limit setpoint must be
higher than the sum of the process value and the hysteresis value. In the event of a
low limit condition, the process value must be higher than the sum of the low limit
setpoint and the hysteresis value.
3.6 Annunciator
An additional (optional) annunciator output is available. If selected in Program mode
(either for USE2 or USE3) the annunciator output operates as follows:
If the limit is, or has been, exceeded AND the Reset key has NOT been pressed since
the limit was exceeded, then the annunciator output will be active.
If the Reset key is pressed while the limit is exceeded, the annunciator output will be
deactivated, even if the limit remains being exceeded.
3.7 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
activate a reset if required.
18
SECTION 4: CONTROL MODE
The Control mode allows viewing of the control status and process variables. Other
modes can be accessed by pressing the SCROLL key until the appropriate mode is
displayed, then pressing the DOWN key.
CONTROL SETPOINT

SECTION 6: CONFIGURATION
All configurable parameters are provided in Table 6-1. This table illustrates the display
sequence, parameter adjustment and factory setting for each step.
Depression of the SCROLL key will cycle the display.
To enter the Configuration mode, press and release the SCROLL key until ConF is
displayed. Use the DOWN key to enter the Configuration mode. Depress and release
the SCROLL key to sequence through the parameters and their values, alternately
showing the parameter code in the lower display with the upper display blank, then the
parameter code with the parameter value in the upper display. Use the UP and DOWN
keys to adjust the parameter values.
After adjusting a parameter, the upper 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 RESET key, and the upper display will stop flashing. After confirming a
change, press the SCROLL key to proceed to the next parameter.
The DOWN key may also be used to advance to the next parameter when a parameter
code is showing in the lower display and the upper display is blank. This is a faster way
of scrolling through the parameter list.
To exit the Configuration mode, press the UP key whenever a parameter code is
displayed in the lower display and the upper display is blank. The instrument will
automatically exit the Configuration mode if no key is pressed in one minute.
DEFAULT PARAMETER INDICATION
If a parameter value, such as Input Select, was changed while in the Configuration
mode, a decimal point after each digit will be lit when returning to the Control mode.
This display indicates all Setup mode parameters have been set to their default
condition. To clear this condition, enter the Setup mode and make a parameter value
change and review each parameter for its proper setting.

SECTION 8: ENABLE MODE
To enter the Enable mode, press and hold the SCROLL key. The display flashes for
about 5 seconds, then returns to a normal display for about 5 more seconds, then
displays EnAb. Release the keys, the display should show ESP. Pressing the DOWN
key will display the Enable mode codes in the following sequence:
ESP – ECon – ESEt
Pressing the SCROLL key will display the Enable mode codes with the upper display
blank. The next depression of the SCROLL key will add the Enable code status (ON or
OFF) to the upper display. With the Enable code status displayed, use the UP key to
change the status to ON and the DOWN key to change the status to OFF.
To exit the Enable mode, press the UP key with any Enable mode code displayed in the

SECTION 9: CALIBRATION
NOTE: Calibration should be attempted only on instruments on which calibration errors
have been encountered (see calibration check).
EQUIPMENT REQUIRED:
1. Input source with accuracy better than +/- 0.05% of reading.
a. Thermocouple: T/C simulator, K type with compensated leads
b. DC: 0 to 50 mV OR
0 to 10 V OR
0 to 20 mA
c. RTD: Decade resistance box with 3 wire input
2. MIC1162 case wired for appropriate input voltage supply (90 to 264 VAC, 50/60
Hz)
PROCEDURE:
1. Before applying power, position the input conditioning jumpers on the CPU PWA
as appropriate. See Figure A-1 and A-2 in Appendix A.
2. Connect the appropriate input from the Input Source. Set the Input Source as
follows:
INPUT TYPE
DC 0 - 50 mV 50 mVDC
DC 0 - 10 V
DC 0 - 20 mA 20 mADC
RTD
T/C (Type K)
INPUT SOURCE
10 VDC
200 ohms
0° C
3. Apply power to the instrument and leave powered for five (5) minutes for RTD
and DC inputs OR thirty (30) minutes for T/C inputs, then power down.
29
4. Apply power to the instrument and within 30 seconds of power-up, press and
hold the DOWN and SCROLL keys simultaneously for about 5 seconds. The
upper display will show ip_1 and the lower display will show CAL.
5. Use the UP/DOWN keys as required to change the input type number as
required:
CAL INPUT NO. INPUT TYPE
1
2
3
4
5
DC 0 - 50 mv
DC 0 - 10 V
DC 0 - 20 mA
RTD
Thermocouple
NOTE: If required, only one input type may be calibrated. EXCEPTION: If it is required
to calibrate the thermocouple input (Input Type 5), it is necessary to calibrate the DC 0 50 mV (Input Type 1) first.
6. Press the RESET key, the upper display will show _ _ _ _.
7. After a few seconds, the upper display will show ip_X, where X is the CAL INPUT
No., if the calibration was successful. If the upper display shows FAIL, the
calibration was not successful - check the jumper positions, wiring, CAL INPUT
No. and try again.
8. To calibrate all inputs, repeat steps 2 through 7 for each of the other input types.
9. The calibration procedure is now complete. Disconnect power, remove input
connections.
30
CALIBRATION CHECK
(See Configuration Mode, Appendix A, and Appendix B.)
1. Power up the instrument and allow to stabilize for at least 5 minutes (RTD and
DC) or 30 minutes for T/C input.
2. After the stabilization period, connect the appropriate input device and check a
number of input points.

APPENDIX B: HARDWARE DEFINITION CODE
The Hardware Definition Code is used to represent the hardware installed (input type,
Output 2 type and Output 3 type); this must be compatible with the hardware actually
installed. It can be accessed, with the instrument in Configuration mode, by
simultaneously depressing the DOWN and SCROLL keys. 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
the third digit is Output 2 type:
0=Output 2 not installed
1 =Relay (Alarm Only)
the fourth digit is Output 3 type:
O=Output 3 not installed
1 =Relay (Alarm 1 only)
2=SSR (not available)
3=DC 0-10V (retransmit only)
4=DC 0-20mA (retransmit only)
5=DC 0-5V (retransmit only)
7=DC 4-2OmA (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.
35
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, and rrES indicates
the presence of the remote reset option.
The code may be changed by pressing the UP and DOWN keys. The RESET key must
be pressed when the correct code is displayed.
NOTE: It is essential that this code is changed whenever there is a change to the
instrument's hardware configuration (change of input/output type,
alarm/retransmit output added/removed 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.
