Product Description 1.1

1.1.1 GENERAL

This instrument is a microprocessor based single loop controller capable of measuring, displaying and controlling temperature, pressure, flow, and level from a variety of inputs. Most heating outputs are easily tuned using the instrument’s Auto Tune function with several choices for control algorithms and control responses.

Control functions, alarm settings and other parameters are easily entered through the front keypad. All user's data can be protected from unauthorized changes with it’s Enable mode security system. Battery back-up 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. Thermocouple and RTD linearization, as well as thermocouple cold junction compensation is performed automatically. The sensor input is isolated . The instrument can be specified to operate on either 115VAC or 230VAC power at 50/60Hz. It is housed in an extruded aluminum enclosure suitable for panel mounting and may be surface mounted using an optional adaptor. For installation in washdown areas, a watertight cover is available (see the instrument price list order matrix).

1.1.2 DISPLAYS

Each instrument is provided with dual digital displays and status indicators as shown in Figure 1-1. The upper digital display is programmable to show the process variable or the deviation from setpoint value. The lower digital display will be the active setpoint value or the percentage of the proportional output indicated by the indicator light. Status indication is as shown (Figure 1-1). Display resolution is programmable for 0 to 3 decimal places depending upon the input type selected.

PAGE 6

1.1.3 CONTROL

The instrument can be programmed for on-off, time proportioning, current proportioning, or position proportioning control implementations depending on the output(s) specified for the instrument in the model number. The Auto Tune function can be used for a heating output assigned to output 1 at the Setpoint 1 value. A second control output is an available option. Proportional control implementations are provided with fully programmable separate PID

parameters.

1.1.4 ALARM

Alarm indication is standard on all instruments. 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 the band). Alarm status is indicated by LED. An alarm output can be provided by assigning any output(s) SPST relay(s) or SSR Driver(s) to the alarm.

1.1.5 PROCESS VALUE RE-TRANSMISSION OUTPUT

If an instrument is specified with a mADC current output, this output may be programmed to operate as a process value re-transmission output (range scaled by user). If an output is used as a process value output, it is not available for use as a control output.

Installation and Wiring 2.1

Prior to proceeding with installation, verify the AC power input required by the instrument. AC power input is either 115 VAC or 230 VAC and is specified in the model number and on the wiring label affixed to the instrument housing. See Figure 2-4 (page 12) for a wiring label description.

230 VAC models may be converted to 115 VAC operation by the user by changing the position of jumpers soldered on the Power Supply Board, see Appendix A-1 (page 50) for details. (Note: 115VAC units cannot be field converted to 230VAC)

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, loosen the locking screw located in the lower center of the instrument’s front panel. Pull the entire instrument straight out of the housing. During re-installation, the vertically mounted circuit boards should be properly aligned in the housing. Be sure that the instrument is installed in the original housing. This can be verified by matching the serial number on the unit to the serial number on the housing. (Serial numbers are located on the inside of the housing enclosure and on the label on the underside of the front panel). This will insure that each instrument is accurate to its published specifications. The ambient compensator on the rear of the housing enclosure is calibrated to the electronics of the instrument at the factory.

Recommended panel opening sizes are illustrated below (Figure 2-1). After the opening is properly cut, insert the instrument housing into the panel opening. Insert the two panhead screws provided, through the holes in the mounting bracket into the holes in the rear of the instrument as shown in Figure 2-1. Firmly tighten the screws. Instruments are shipped standard for panel mounting. To surface mount, an adaptor is required and should be specified when ordering. For installation in wash-down areas, a watertight cover is available.

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 Before using any instrument near the devices listed, the instructions below should be fol-

lowed:

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

Earth Ground The instrument includes noise suppression components that require an earth ground connection 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. Use a 12 gauge (or heavier) insulated stranded wire.

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.

2.2.1.3 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)

• SPST Relays

• SSR driver output

• 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, 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 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 necessary. sometimes in severe electrical environments, the amount of noise is so great tht it has to be suppressed at the source. Many manufacturers of relays, contactors, etc., supply "surge suppressors" which mount on the noise source.

For these devices that do not have surge suppressors supplied, RC (resistance-capacitance) networks and/or MOC (,etal 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 2-2. Aditional protection may be provided by adding an RC network across the MOV.

Coil

220 ohms

115V 1/4W 230V 1W

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, page 10.

2.2.2 SENSOR PLACEMENT (Thermocouple or RTD)

Two wire RTD's should be used only with lead lengths less then 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 positoned 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 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 11

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 temperatire 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

(Continued from page 11) 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

AUTO/MANUAL KEY

This key is used to enter the Manual mode (Standby) of operation from the Control mode and visa versa.

AUTO TUNE KEY

This key is used to initiate the Auto Tuning of the Output 1 proportional output for heating applications. If Auto Tune is being performed, pressing this key will abort the Auto Tune function. The instrument will Auto Tune the process to control at the Setpoint 1 value.

SP1/SP2 KEY

This key is used to change the setpoint from one preselected value to the other preselected value.

SCROLL KEY

This key is used to:

1. Display enabled modes of operation

2. Display a mode parameter value

3. Advance display from a parameter value to the next parameter code

4. Exit some calibration/test functions

5. Used with other keys:

A. With UP key to view output percentages of proportional output(s)

B. With DOWN key

1. On power up to alter model number

2. Enter calibration /test functions

3. To view output percentage of proportional Output 2

UP KEY

This key is used to:

1. Increase displayed parameter value

2. Increase setpoint (press and hold)

3. With a parameter code displayed

A. Press once to exit mode

B. Press twice to enter Control mode

4. Used with other keys

A. In Control mode with SCROLL key to view output percentage of proportional

output 1.

B. With DOWN Key

2. Decrease setpoint (press and hold)

3. Enter modes

4. While in a mode, will sequence the parameter codes

5. Used with other keys

A. With SCROLL key

1. On power up to alter model number

2. Enter calibration/test functions

3. To view the output percentage of proportional output 2

B. With UP key

1. On power up resets instrument

2. Lamp test (press and release)

3. Enter enable mode (press and hold)

3.2.2 CONFIGURATION DISPLAYS

During configuration, the upper display shows the parameter codes. The lower digital display shows the parameter value. During operation, the upper display is used to indicate process value or deviation from setpoint. The lower display can be used to indicate setpoint value or proportional output percentage.

3.2.3 MODE SELECTION

If the instrument is in the Control mode, repeated depressions of the SCROLL key will cause the instrument to display the code corresponding to each mode that is enabled. To enter a mode, with the mode displayed, depress the DOWN key. Entry into any mode except the Control, Tune and Enable modes will cause the output(s) to turn off.

Configuration Summary 3.3

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

The instrument is provided with a “time-out” feature. If the instrument is in any mode, other than the Control mode, and no keypad activity takes place for 30 seconds, the mode will be exited automatically. The instrument will then display the code for the respective mode. If a mode code is displayed for five seconds with no key stroke activity the “time-out” will cause the instrument to return to the Control mode of operation.

3.3.1 ENABLE MODE CONFIGURATION

The Enable Mode provides a means of enabling or disabling access to setpoint changes and each of the non-control modes. In the Enable mode, each mode except Control, will be displayed. Either “on” (enabled) or “oFF” (disabled) may be selected. See Table 3-1 (page

24) for the Enable mode procedure. For additional security the Enable mode may be locked out by using a hardware jumper, JU 2, located on the Processor board. See Appendix A-2 (page 65).

3.3.2 PROGRAM MODE CONFIGURATION

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 29) for illustrative purposes. Only those parameters that are applicable to the hardware options chosen or to previous parameter selections will be displayed.

3.3.3 TUNE MODE CONFIGURATION

The Tune mode is used to adjust the tuning parameters and the alarm setting needed for operation of the instrument. If Auto Tuning is used to determine the parameters for the heating output (Output 1), those parameters in the Tune mode (except Cycle time) need not be configured.

TABLE 3-1 ENABLE MODE CONFIGURATION PROCEDURE

To enter the Enable mode, depress and hold the UP and DOWN keys. All display lamps will light, after ten seconds the upper display will read EnAb. If EnAb does not appear, check the position of the Enable mode jumper, JU 2, located on the Processor board (See Appendix A-2, page 65). The jumper must be in the unlocked position for the Enable mode to function. Release the keys and the upper display will then change to EtSt. Depress the SCROLL key to review the state (on or off) of the mode (will appear on the lower display). Use the UP key to enable a mode that is off. Use the DOWN key to disable a mode that is on. When all selections have been made, to exit the Enable mode depress the UP key with a mode code displayed EtSt, ECAL, etc.
