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.

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 operate on either 115VAC or 230VAC power at 50/60Hz. It is housed in an extruded aluminum enclosure suitable for panel mounting. It may be surface mounted using an optional adaptor.

1.1.2 DISPLAYS

Each instrument is provided with a digital display and status indicators as shown in Figure 1-1. The digital display is programmable to show the process variable only, process variable and setpoint, deviation from setpoint only, deviation and setpoint, or setpoint continuously. 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 model number. 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 EXTENDED	FEATURES	SOFTWARE
EA Software Features
Fast Scan		Provides an optional faster scan rate of 3 scans per second.
		Normal scan is one scan per second.
Process Rounding		Provides rounding of the process value displayed to reduce display
		fluctuation. For example, the displayed value can be rounded to
		the nearest 5 (display -5, 0, 5, 10, etc.). This is for display only and
		does not affect the control action.
Extended Current		The current outputs available can be extended to include 0-20mA
Output Ranges		and 0-5VDC (with the appropriate shunt resistor), rather than the
		standard 4-20mA and 1-5VDC outputs.
Process/Setpoint		The process or setpoint value can be scaled over any desired
Value Retransmit		range and retransmitted using one of the current outputs. (This
Capability		precludes the use of the output for control).
Percent Output		Provides a relay actuation based upon a proportional output being
Relay Actuation		above or below a specified value.
Contact Closure Sensing		This feature provides the following action: When a contact closure
for SP=PV		is sensed, the setpoint will be set equal to the current process
		value. This is only done on the transition from open to closed, and
		not continuously while the switch is closed.
EB Software Features
Setpoint Ramp	Provides a limitation on how fast the process value will ramp to setpoint by
Rate	limiting the rate of change of an internal setpoint used for control versus
	the setpoint the operator specifies.

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 13) 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 59) for details.

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 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

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 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.

PAGE 9

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 a possible to the coil. See Figure 2-2. Additional protection may be provided by adding an RC network across the MOV.

(Continued on next page)

PAGE 10

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.

2.2.2 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 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

PAGE 11

THERMOCOUPLE LEAD RESISTANCE

Thermocouple lead length can affect instrument 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:

A 1/4 Din unit 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 is 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

Configuration and Operation 3.1

3.1.1 POWER UP PROCEDURE

Verify all electrical connections have been properly made before applying power to the instrument.

If the instrument is being configured (set up) for the first time, it may be desirable to disconnect the controller output connections. The instrument will go into the Control mode following the power up sequence and the output(s) may turn on. During power up, the seven digit model number will be displayed. Next, the software revision level will be displayed, followed by the EPROM tab number. Instrument self test 1 through 3 will take place as they are displayed. After completion of the tests Ctrl will be displayed for 3 seconds. At this time another mode of operation may be selected by pressing the SCROLL key.

3.1.2 CONFIGURATION PROCEDURE

Parameter selections and data entry are made via the front keypad. To ease configuration and operation, the user selectable features have been divided into several sections (modes). Data and parameter entries are made by stepping through each mode and making an appropriate response or entry to each step as necessary for the application.
