1.1.1 GENERAL
This instrument is a microprocessor based profiling controller capable of measuring,
displaying, and controlling a process variable from a variety of inputs. Applications
include temperature, pressure, level, flow, and others.
Control functions, alarm settings and other parameters are easily entered via the front
keypad. All user data can be protected from unauthorized changes by the Enable
mode security system, and is protected against loss from AC power failure by battery
back-up.
The process input is user configurable to directly connect to either thermocouple,
RTD, mVDC, VDC, or mADC inputs. depending on the input type specified. Thermo-
couple and RTD linearization, as well as thermocouple cold junction compensation, is
performed automatically. The instrument's process input is isolated from the rest of the
instrument.
The instrument can be ordered to operate on either 115VAC or 230VAC power at 50/
60Hz. The instrument is housed in an extruded aluminum enclosure suitable for panel
mounting.
FIGURE1-1
1.1.2DISPLAYS
Each instrument is provided with a digital display and status indicators as shown in
Figure 1-1. The digital display is programmable to display the process value only,
process and setpoint, deviation from setpoint only, deviation and setpoint, or setpoint
continuously.
Status indication is provided for Alarm , Output 1, Output 2, degree C, degree F,
engineering units, Manual operation, Segment 1 thru 6, Ramp, and Soak.
Display resolution is programmable for 0.1 or 1 degree for thermocouple and RTD
inputs, and 0.001, 0.01, 0.1, or 1 unit for volt, mV input types.

PAGE 6
1.1.3CONTROL
Instruments can be programmed for On-Off, Time Proportioning, Current Proportioning, or
Position Proportioning control implementations. Selectable direct or reverse control action is
also provided. Proportional control implementations are provided with fully programmable PID
parameters.
Automatic to Manual switching is easily accomplished via the Standby mode . Switching is
bumpless, and while in manual, manipulation of proportional outputs is possible.
Other standard control features include control output limits, setpoint limits, anti-reset windup
control, and a unique Automatic Transfer function, which, if configured, allows manual control
of the process until setpoint is reached, at which time the unit will automatically transfer from
manual to automatic control.
Remote Run-Hold capability can be provided via the Auxiliary Input.
1.1.4PROGRAMMABLESETPOINTPROFILES
Up to eight profiles can be programmed on any of these Profile Controllers. Each of the
eight profiles can contain up to six segments. Each segment contains a ramp and a soak
operation. Profiles can be programmed to run continuously or any number of times up to
9999. A combination of profiles may be combined for back to back execution. This has the
affect of acting as a single profile of more than six segments.
Assured Soak is provided with the use of two programmable parameters that will activate an
Auto/Hold feature. This feature will place a running profile in the Hold condition and prohibit a
Soak operation from starting or completing if an acceptable process value is not reached and
then maintained.
Event outputs may also be provided. Up to three events may be assigned and can be turned
on or off at the beginning of each ramp and soak.
1.1.5ALARMS
Alarm settings are fully programmable. Alarm type may be set as Process direct or reverse
(High or Low), Deviation direct or reverse (above or below setpoint), or Deviation Band type
(closed or open within band).
Alarm outputs can be provided by assigning any specified relays (SPST or SSR driver) to the
respective alarm.
1.1.6DIGITALCOMMUNICATIONS
The instrument can be provided with an RS-422/485 communications port which allows
bi-directional multidrop communications with a supervisory computer.

Unpacking2.2
Remove the instrument from the carton and inspect it for any damage due to shipment. If any
damage is noticed due to transit, report and file a claim with the carrier. Write the model
number and serial number of the instrument on the front cover of this Operation Manual for
future reference when corresponding with the factory.
Location2.3
Locate the instrument away from excessive moisture, oil, dust, and vibration. Do not subject
the instrument to operating temperatures outside of 0 to 55˚ C (32°to 131°F).
Mounting2.4
Figure 2-1 (page 8) shows installation view and physical dimensions for the panel mounted
instrument.
The electronics can be removed from the housing for installation, if so desired. To remove,
loosen the locking screw centered on the bottom face of the unit. The instrument pulls
straight out. When installing, be sure that the verically mounted circuit boards are inserted in
the correct grooves in the top and bottom of the housing. Also make sure the screw lock is
sufficiently tight. When installing multiple instruments, be sure to reinsert the proper
instrument into its correct enclosure by matching the serial number with the number inside the
housing. This will insure that the accuracy of the control will be within the published
specifications. The ambient compensator on the rear of the enclosure is calibrated to the
electronics at the factory.
Cut the panel cutout to the dimensions shown in Figure 2-1 (page 8). Insert the instrument
housing into the panel cutout and install the mounting bracket. Place the mounting screws on
the back of the housing and tighten until the instrument is rigidly mounted. Do not
overtighten.
A surface mounting kit is available - part number 64405801. For installation of the instrument
in areas subjected to washdowns, a water tight cover option is available (part # 64417801).

2.5.1WIRINGGUIDELINES
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.
2.5.1.1 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
Before using any instrument near the devices 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 practicies have been followed.
2.5.1.2 AC POWER WIRING
Earth Ground
The instrument includes noise suppression components that require an earth ground connec-
tion to function. To verify that a good earth ground is being attached, make a resistance
check from the instrument chassis to the nearest metal water pipe or proven earth ground.
This reading should not exceed 100 ohms.
Neutral (For 115VAC)
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.
2.5.1.3 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)
* SPST Relays
* SSR driver outputs
* AC power
The only wires that should be 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 secon-
dary 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.
2.5.1.4 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 at the sensor, transmitter or transducer.

PAGE 10
2.5.1.5 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 thta 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 con-
nected in parallel and as close as possible to the coil. See Figure 2-2. 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 2-3.

2.5.2 SENSORPLACEMENT(ThermocoupleorRTD)
If the temperature probe is to be sufnected 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.
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 follow-
ing equation:
Terr = TLe * L where; TLe = value from appropriate table below
L = length of leadwire in thousands of feet

Example:
An MIC 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/1000 ft) from Table 2
Terr = 2.47 (°F/1000 ft) * 660 ft
Terr = 1.6 °F

PAGE 12
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
TABLE 3 - 3 Wire RTD
AWG No. Error °C Error °F
10 +/- 0.04 +/- 0.07
12 +/- 0.07 +/- 0.11
14 +/- 0.10 +/- 0.18
16 +/- 0.16 +/- 0.29
18 +/- 0.26 +/- 0.46
20 +/- 0.41 +/- 0.73
24 +/- 0.65 +/- 1.17
TABLE 4 - 2 Wire RTD
AWG No. Error °C Error °F
10 +/- 5.32 +/- 9.31
12 +/- 9.31 +/- 14.6
14 +/- 13.3 +/- 23.9
16 +/- 21.3 +/- 38.6
18 +/- 34.6 +/- 61.2
20 +/- 54.5 +/- 97.1
24 +/- 86.5 +/- 155.6
Example:
An application uses 2000 feet of 18 AWG copper lead wire for a 3 wire RTD sensor. What is
the worst case error due to this leadwire length?
Terr = TLe * L
TLe = +/- .46 (°F/1000 ft) from Table 3
Terr = +/- .46 (°F/1000 ft) * 2000 ft
Terr = +/- 0.92°F
