Thank you for selecting the 531 PID Backup Station. It is the most sophisticated instrument in its class and will provide you with years of reliable, trouble-free performance.

OUTPUTS

HOST Signal Control Output Alarm(s) Serial Communications

The 531 automatically provides PID backup control for critical control loops. In Host Mode, the control signal passes from the Host device through the 531 without any degradation. A Host device may be a PLC, DCS, or process controller. The 531 switches to Automatic (PID) Mode upon keypad selection, digital input, or loss of the Host signal, and generates a control signal based on its own PID calculations. The control setpoint may be one or two preset setpoints, or transmitted to the 531. The 531 can also be switched to Manual Mode, in which the operator can manually adjust the output. The 531 will transfer/return to Host Mode upon keypad selection, opening of the digital input or return of the Host signal.

CONFIRMING WHA T IS INCLUDED

With your 531 PID Backup Station, you should have received:

• 1 531 User’s Manual

• Mounting hardware set

• 1 sheet of engineering unit adhesive labels

• 1 Terminal label You can determine the installed outputs of your station by comparing your product

number to the Order Code below. The product number is printed on the label on the top of the controller case.

Specifications and information subject to change without notice.

Note: that the 531 PID Backup Station is not a point of failure; removing it from the case or powering down while in Host Mode will not disturb the Host signal.

2 Chapter 1, Introduction 531 User's Manual

Host Mode: The 531 operates as a remote station that passes a CV directly from a host to a controlled device. In this mode, the SP but not the CV (output) can be altered. Special “set up” parameters can be accessed, and the 531 can be transferred into either of the other operating modes.

Automatic Mode: The 531 sends output to the final device as provided by its own PID calculations. In this mode, the SP but not the CV (output) can be altered. The “set up” parameters may not be accessed, but the 531 can be transferred to either of the other operating modes.

Manual Mode. An operator provides manual output to the controlled device. Both the SP and the CV can be altered, and the 531 can be transferred to either of the other two operating modes.

The 531 also has a set up, or “configuration” mode in which the user configures the special functions of the 531, like inputs and outputs, alarms and PID operation. There are 9 menus in set up mode: eight are for instrument set up, and the ninth, OPERATION, configures the operational aspects of the 531.

WHERE TO GO NEXT

• First time users should read through this entire manual. Continue to Chapter 2 for basic interface and operation information. Then read Chapter 3 for important installation guidelines.

• Experienced users may continue on to Chapter 5 for details on the configuration features of the 531.

Latching Alarms

A latching alarm holds its alarm state even after the process leaves the alarm condition. This is useful for stations that will not be continuously monitored by an operator. A latching alarm can be configured to be acknowledgeable while in the alarm condition, OR only after the process leaves the alarm condition. A non-latching alarm will clear itself as soon as the process leaves the alarm condition.

Limit Sequence

An alarm can be configured to be both latching and not acknowledgeable. In this case, the alarm is acknowledgeable only after the process has left the alarm condition. This is often referred to as a limit sequence.

For more on alarms, see Chapter 6.

CHAPTER 3 HARDWARE CONFIGURA TION

Hardware

The 531 hardware configuration determines which outputs are available and the types of indicator signals that will be used.

Your station comes factory set with the following:

• All the specified modules and options installed (see product label and compare to Order Code in Chapter 1).

• Process variable and remote setpoint inputs set to accept a milliamp input.

CAUTION!

Static discharge will cause damage to equipment. Always ground yourself with a wrist grounding strap when handling electronics to prevent static discharge.

• Relay outputs set to normally open

The locations of certain jumpers and modules on the printed circuit boards will allow different types of inputs and outputs to be connected to the stations. Figure 3.1 shows the position of these circuit boards inside the station. To access these boards:

1. With power off, loosen the two captive front screws with a Phillips screwdriver.

2. Gently slide the chassis out of the case by pulling on the front face plate assembly at the bezel. Remove the two screws.

NOTE:

If you would like your controller configured at the factory, please consult an application engineer.

NOTE:

Your hardware configuration will influence the available set up options in Chapter 5.

CHAPTER 4 MOUNTING AND WIRING

The 531 PID Backup Station is thoroughly tested, calibrated and “burned in” at the factory, so your station is ready to install. But before you begin, read this chapter carefully and take great care in planning your system. A properly designed system can help prevent problems such as electrical noise disturbances and dangerous conditions.

SYSTEM PLANNING

A. Consider the Noise Factor

• For improved electrical noise immunity, install the station as far away as possible from motors, relays and other similar noise generators.

• Do not run low power (sensor input) lines in the same bundle as AC power lines. Grouping these lines in the same bundle can create electrical noise interference.

B. Wiring Practice Resources

An excellent resource about good wiring practices is the IEEE Standard No. 518-1982 and is available from IEEE, Inc., 345 East 47th Street, New York, NY 10017, (212) 705-7900.

Mount/Wire

WARNING!

To avoid electric shock, DO NOT connect AC power wiring at the source distribution panel until all wiring connections are complete.

To avoid shock hazard and reduced noise immunity for your system,

terminal 9 must be grounded.

MOUNTING THE STA TION

A. Make the panel cutout

The station fits in a standard 1/4 DIN cutout. You may mount your station in any panel with a thickness from .06 to .275 inches (1.5 mm to 7.0 mm). See Figure 4.1 for dimensions.

If you make a mistake in the panel cutout, you can use a “Goof Plate” (Repair Part #512-014).

B. Establish a waterproof seal

The station front face (keys, display, and bezel) are NEMA 4X rated (waterproof).

1. The panel cutout is precise.

2. You use a fresh gasket.

3. The edge of the cutout is free from burrs and “waves”.

4. The case of the station are centered in the cutout. If you require a waterproof seal but have difficulty with these requirements,

apply a bead of caulk or silicone sealant behind the panel around the perimeter of the case.

Figure 4.2 Mounting Brackets

Bezel

MOUNTING BRACKET (1 EA. SIDE)

C. Mount station into panel:

The instrument enclosure mounting must be grounded. You will need a long Phillips screw driver (#2).

1. Place bezel gasket around the station case (starting at the back of the station). Then, slide the gasket against the back of the bezel.

2. With the bezel gasket in place, insert the station into the panel cutout from the front of the panel.

3. From behind the panel, insert the mounting clips (one on each side), as shown in Figure 4.2.

4. Gradually tighten the mounting bracket screws.

5. Tighten the screws securely and check bezel gasket to ensure a tight,

even seal.

Slide gasket on from this end.

NOTE:

All wiring and fusing should conform to the National Electric Code and to any locally applicable codes.

WIRING THE 531 OUTPUTS

• Output 1 is available for use as an ALARM or HOST FLAG with installation of a Mechanical Relay, Solid State Relay (Triac) module, or SSR Drive.

• The 531 is factory configured with an Analog module in Output 2.

• The 531 is factory configured with Mechanical Relays in Outputs 3 and 4.

• The 531 cannot be wired for retransmission.

• A small PC board fits over rear terminals 5 to 8 and 13 to 16.

These instructions explain proper wiring of the 531 for any output module. If you do not know which module(s) have been installed in your station, compare the number on the product label with the Order Code on page 3. To add or change position of jumper 1 or output module 1, refer to Chapter 3.

A. CV Output

• Use terminals 5 and 8 for CV Output as shown in Figure 4.4.

• Use terminals 14 and 15 for CV Input.

B. Mechanical Relay Output

• Use terminals 3 and 4 as shown in Figure 4.4.

• Jumper J1 can be set to normally open (NO) or normally closed (NC)

as desired.

C. Solid State Relay (Triac) Output

• Use terminals 3 and 4 as shown in Figure 4.4.

• Jumper J1 must be set to normally open (NO).

D. DC Logic (SSR Drive) Output

• Use terminals 3 and 4 as shown in Figure 4.4.

• Jumper J1 must be set to normally open (NO).

WARNING!

DO NOT make any modifications to the factory setting of output modules 2, 3 and 4; this will place the product in an invalid and undefined state.

Use a 60Ω to 100Ω terminating resistor connected to the two data terminals of the final device on the line.

WIRING FOR SERIAL COMMUNICA TIONS

You must have this option installed on your 531 in order to use serial communications. Refer to Figure 4.5.

• Use a twisted shielded pair of wires to connect the host and field units. Belden #9414 foil shield has superior noise rejection characteristics. #8441 braid shield 22-gauge wire has more flexibility.

• The maximum recommended length of the RS 485 line is 4000 ft.

• Termination resistors are required at the host and the last device on the line. Some RS 485 cards/converters already have a terminating resistor. We recommend using RS-232/RS-485 converter (prod. no. 500-485).

CHAPTER 5 SOFTW ARE CONFIGURATION

MODE OVERVIEW

Upon power up, as well as during “normal” operation, the 531 is in one of its operating modes - Host, Automatic or Manual.

The 531 also has a set up (configuration) mode that lets you access options for adjusting the operation and display of the station. “Set up” is divided into two groups; one for the first eight menus (as listed below), and another for the OPERATIONS menu by itself.

Figure 5.1 illustrates the relationships among the three operating modes and nine set up menus.

The 8 set up menus can by accessed only when the 531 is in Host or Manual Mode. The OPERATIONS set up menu can be accessed when the 531 is in

Automatic, Host or Manual Mode.

MENUS

A menu is a group of configuration control parameters. While in these set up menus, the name of the menu will appear in the 2nd display. The names of the different parameters within that menu group will then replace the menu name in the 2nd display. The values/options for each parameter will then appear in the 3rd display. Figure 5.1 displays the parts of the menu as used by this manual.

The (possible) menus for the 531 are:

• OPERATIONS To set up special PID control parameters and make adjustments to the transition functions (among operating modes) of the station.

• CONFIG. To configure the input and output hardware assignments.

• LOCAL OUT. To configure the local output control.

• PV INPUT To configure the process variable.

• CUST. LINR To configure the custom linearization curve for the process variable.

• RSP INPUT To configure the remote set point.

• ALARMS To configure alarms.

• SECURITY To configure the security function.

• SER. COMM. To configure serial communications.

SMART MENUS

This chapter outlines, in sequence, all menus, parameters, and selections available for the 531. However, the “smart menu” feature of the station allows only those Menus and Parameters to appear that are relevant to your hardware and software configuration, i.e., parameters which do not apply to your

application will not appear on your station’s display.

• Parameters that apply to all configurations appear in this manual as a white on white box (Figure 5.2, left). These parameters are independent of your configuration.

• Parameters that depend on the configuration of the individual station ap- pear as a black on white box (Figure 5.2, right).

Changing one parameter’s selection (or value) may affect another parameter. Refer to the section on the PV INPUT menu for an example on how this can affect your low and high range values.

531 OPERATION

The 531 PID Backup Station provides PID based control backup for critical control loops. It is normally installed between a Host device and final control element. The Host device may be a PLC, DCS or single loop controller (SLC). The final control element may be a valve actuator, positioning device, power control unit for an electric heating element, pump or other control device. The control signal must always be a 4-20mA proportional signal.

Host Mode (Default Mode)

• The HOST key is lit.

• In Host Mode, the 531 is transparent to the control loop; it passes the control signal from the Host device without any degradation.

• The 531 constantly monitors the CV and uses the last good signal as a potential CV for the Automatic Mode.

• The 531 can be removed from the case without disrupting the Host signal; it is not a point of failure.

• The 531 switches to Host Mode due to:

- Return of the Host signal

- Keypad selection

- Closure of a digital contact; or

- Commands through the RS-485 port.

• Upon return of the Host signal, the 531 can be programmed to

- Return control to the Host Mode immediately;

- Ramp to the new CV at a predetermined rate; or

- Remain in the current mode, where the operator can determine whether

or not the Host signal is valid.

Automatic Mode

• Neither the HOST nor MANUAL keys are lit.

• The 531 switches to Automatic (PID) Mode due to:

- Loss of the Host signal

- Keypad selection

- Closure of a digital contact; or

- Commands through the RS-485 port.

• Upon switching to Automatic Mode, the 531 generates a control signal based on PID control.

• The 531 executes a bumpless transfer to the new CV while in PID mode (no ramping needed).

ALARMS

The 531 has 2 alarms available. It indicates alarm conditions by:

• Lighting up the alarm icon(s).

NOTE: Refer to “Alarm Operation” in

Chapter 2 for information on operating alarms.

• Displaying a custom message in the 3rd display

• Illuminating the ACK key if the alarm is acknowledgeable.

Each alarm can be assigned one of 6 different types. Also, by adding an output module, one of the alarms can be tied to a relay output. To assign an alarm:

1. Press FAST + MENU to toggle to the ALARM menu.

2. Press MENU to select the first parameter ALM.TYPE:1 and select its type (choose one of the following) using the

▲▲

▲ and ▼ keys:

▲▲

LOCAL

(Host Flag) If tied to a relay output, a local alarm notifies the Host that the 531 has taken over the output in Manual or Automatic mode. You can choose LOCAL for only one of the alarms. Useful when the Host performs logging functions for Statistical Process Control (SPC), or to prevent reset windup.

HIGH PV

Occurs when the process variable exceeds the alarm setpoint.

LOW PV

Occurs when the process variable goes below the alarm setpoint.

RATE

Use to signal an alarm when the PV changes at a rate greater than that specified by the alarm setpoint and time base. For example, if you have an alarm setpoint of 10 and a time base of 5 seconds, an alarm occurs if the PV changes greater than 10 units in 5 seconds.

BAND

Creates a band twice the size of the alarm setpoint [centered] around the control setpoint. Alarm occurs when the process variable travels outside of this band. For example, if your control setpoint is 500 and the alarm setpoint is 25, the alarm occurs if the PV travels outside of the 475 to 525 range.

Alarm is dependent upon retransmission of the control setpoint. As the control setpoint changes, the band centers itself accordingly.

DEVIATION

Creates a band on one side of the control setpoint. Alarm occurs when the process variable deviates from the control setpoint by an amount greater than the alarm setpoint.

For example, if the control setpoint is 500 and the alarm setpoint is +50 (plus 50), an alarm occurs when the process variable exceeds 550. If your alarm setpoint is –50, the alarm occurs when the process variable drops below 450.

Alarm is dependent upon retransmission of the control setpoint. As the control setpoint changes, the band centers itself accordingly.

HIGH CV

Occurs when the control value exceeds the alarm setpoint.

LOW CV

Occurs when the control value goes below the alarm setpoint.

3. Press the MENU key to select the second parameter ALM.TYPE:2 and select its type using the s and t keys.

Each alarm type (except a LOCAL alarm) has a number of corresponding parameters that must also be set up in the ALARM menu (steps 4 - 11).

Press the MENU key to select the rest of the parameters in the ALARM Menu, and choose their values with the

▲▲

▲ and ▼ keys.

▲▲

4. ALARM SP:1 and ALARM SP:2 Specifies, in engineering units, the point at which the alarm occurs. For a rate-of-change alarm, it specifies the amount of change that must occur

before the alarm activates. A negative value specifies a negative rate-ofchange.

5. DEADBAND:1 and DEADBAND:2 Specifies the range through which the PV must travel before leaving an alarm

condition (see alarm examples at the end of this section).

Applications

NOTE:

The Band and Deviation alarms are not selectable without a PV and a retransmitted SP signal.

NOTE:

The HIGH CV and LOW CV alarms, when selected, operate in both Host and Local modes.

NOTE:

Only those parameters that apply to your particular alarm type will appear as you toggle through the parameters.

Applications

NOTE:

You can specify whether the relay is Normally Open or Normally Closed when configuring the hardware, with jumper selection only for Output 1.

This prevents frequent alarm oscillation or “chattering” if the process variable has stabilized around the alarm point.

6. RELAY:1 Specifies whether the relay will be on or off. ON means the relay is energized,

while OFF means the relay is de-energized when the station is in the alarm condition.

Most applications require the relay to energize. However, limit applications usually require the relay to de-energize.

7. LATCHING:1 and LATCHING:2 If the alarm is latching (YES), the alarm remains active after leaving the alarm

condition unless acknowledged. If the alarm is non-latching (NO) the alarm returns to its non-alarm state when

leaving the alarm condition without being acknowledged.

8. ACK.:1 and ACK.:2 ENABLED allows the operator to acknowledge an alarm at any time, even if the

control process is still in the alarm condition. DISABLED prevents the operator from acknowledging an alarm while the process

is in the alarm condition. When either alarm is available to be acknowledged, the ACK key will be

illuminated. If both alarms are acknowledgable, press the ACK key once to acknowledge alarm #1, then a second time for alarm #2. A latching alarm can always be acknowledged when it is out of the alarm condition.

9. POWER UP:1 and POWER UP:2 If you want the controller to always power up in alarm, regardless of the alarm

condition, then select ALARM. This is an excellent way to activate an alarm if there has been a power failure.

If you never want the controller to power up in alarm, regardless of alarm condition, select DELAYED. The system must leave and reenter the alarm condition before the alarm will activate. This is typically used to avoid alarms during start up.

If you want the system to power up in alarm only if it is in an alarm condition, select NORMAL.

10. MESSAGE:1 and MESSAGE:2 Allows you to enter a nine character message to display when the respective

alarm is active. The first character of the 3rd display will be flashing. Use

▼▼

and

▼ keys to scroll through character set for each character. Press FAST

▼▼

to enter the selection and move to the next digit. Press MENU to advance to next parameter.

11. RATE TIME Defines the time period over which a specific change in process variable must

occur for the rate alarm to be activated. The amount of change is defined by the alarm setpoint. The rate-of-change is defined as the amount of change divided by the time period. In general, for a given rate-of-change, the shorter the time period, the more sensitive the rate alarm.

Examples:

1. If the alarm setpoint is set to 10 and the time base is set to 1 second, the rate of change is 10 units per second. The process variable would only have to experience a ten unit change over a short period of time.

2. If the alarm setpoint is set to 100 and the time base set to 10, the rate of change is also 10 units per second. The PV would require a 100 unit change over a ten second period.

DIGIT AL INPUTS

This optional feature is only available if ordered originally from the factory. For a set of 5 digital inputs can be ordered, order Product #531 -xxxxxxDx00.

If more than one digital input is closed, then the last one closed generally has priority over the others.

A closed digital input may be overridden by: another digital input, a keyboard operation, or an automatic function. A closed digital input that was overridden must be opened, in order to be “re-armed”.

If one digital input is closed and selects LOCAL, and then REMOTE is keyboard selected, the keyboard selection takes precedence.

WA TCHDOG MONIT OR

This feature is only available with the factory installed five digital inputs. The 531 normally uses the presence of the CV for determining Host failure. In

some cases, however, a Host can “lock up” or “hang up,” leaving its mA control output frozen at a constant value.

To protect against this type of Host failure, one of the Host relay outputs may be programmed to provide a pulse, or “watchdog,” output. A 531 digital input can be set to monitor this pulse. If the pulse state does not change (toggle) in a 0.4 to 2.5 second period, then the 531 will record the Host’s CV signal as unreliable, and appropriately report a lost CV as Host failure.

To configure a digital input as a watchdog monitor:

1. Press FAST + MENU to toggle to the CONFIG. menu.

2. Press MENU to access parameter CONTACT:1 (or 2, 3, 4 or 5). Use the

INPUT LINEARIZA TION

Thermocouple and RTD Linearization

When you select a thermocouple or RTD input, the station automatically linearizes the incoming signal. The station uses internal lookup tables to provide an accurate reading of the temperature being sensed.

Square Root Linearization

Many flow transmitters generate a nonlinear signal corresponding to the flow being measured. The station must have the square root of this signal in order to use it. The station has the capability to perform this function for itself.

To utilize this feature, you must have a voltage or milliamp input.

1. Press FAST + MENU to toggle to the PV INPUT Menu .

▲▲

2. Press MENU to access the LINEARIZE parameters, and use the assign value SQR. ROOT.

For the first 1% of the input span, the input is treated in a linear fashion. After that, the input is a value calculated using the formula shown in Figure 6.2.

Custom Linearization

Custom linearization allows you to take virtually any nonlinear signal and linearize it using a 15-point straight line approximation curve. Typical applications are linearizing signals from nonlinear transducers, or controlling volume based on level readings for irregularly-shaped vessels. To define the function, you must enter data point pairs—the engineering units corresponding to a particular voltage or current input.

RAMP T O A CONTROL VALUE

The “ramp to control value” function is useful for all other transitions where the rate-of-change of the control value must be limited, or under any circumstances where there is likely to be a significant difference between control values at the mode transition time.

Under normal operating conditions, the 531 passes the Host signal to the final control element without modification, and stores the current CV value with each cycle of the CPU. Upon loss of the Host signal (or switching out of Host Mode), the 531:

• Switches to Automatic Mode (LOST HOST = AUTO.LOCAL), automatically initiating a bumpless transfer from the last known good CV to the new PIDderived CV;

• Switches to Manual Mode using the last known good value from the Host (LOST HOST = MAN.LAST); or

• Switches to Manual Mode using one of two preset outputs (LOST HOST = MAN.OUT1 or MAN.OUT2).

A preset output value may be considerably different from the Host CV, so the transfer may not be bumpless. The ramp to control value function allows the operator to select the ramping time for the output value change, thus smoothing the transition.

1. Press the MENU key to access the OPERATIONS Menu .

2. MAN. RAMP selects the ramping percentage (rate) for gradually changing output to the predefined Manual output value (when switching out of Host Mode).

The choices are OFF, or 0.1% to 999.9% per minute. 0.1% per minute is equal to 6.0% per hour, and 999.9% per minute is equal to 16.7% per second.

3. HOST.RAMP selects the ramping percentage for gradually changing output to the Host CV (when returning to Host Mode).

SECURITY

Applications

The security function contains parameters that allow the user to lock out the selective functions of the station. Security only locks out the keypad commands — digital inputs and serial communications are not affected.

1. Press the FAST + MENU keys to toggle to the SECURITY Menu . Press MENU to access each of the following parameters, and the ▲ and ▼ keys to set their values.

2. SEC. CODE Define the security code using the ▲ and ▼ keys. This parameter does not

appear unless all functions are unlocked. The security function is compromised if the security code is left at zero (0).

3. HOST KEY Selects lockout status of the HOST key.

4. MAN. KEY Selects whether the MANUAL key should be LOCKED or UNLOCKED to

prevent the operator from placing the 531 in Manual Mode. Transfer to Manual Mode is then accomplished by loss of Host signal, digital contact closure or Serial Communications.

5. MAN. OUT Selects whether changes to the output (via the ▲ and ▼ keys) in Manual Mode

should be LOCKED or UNLOCKED.

6. LOCAL SP Selects whether changes to the setpoint (via the ▲ and ▼ keys) in any

operating mode should be LOCKED or UNLOCKED.

locking any other feature. The station

will not display this parameter if any others have been LOCKED. You would have to unlock all other parameters in order to view the SEC. CODE again.

Selects whether the ACK key should be LOCKED or UNLOCKED for acknowledging alarms.

8. OPERATION Selects whether access to the OPERATIONS configuration menu should

be LOCKED or UNLOCKED.

9. CONFIGURE Selects whether changes to the other configuration parameters should be

LOCKED or UNLOCKED. You must set CONFIGURE to LOCKED if you want full security. If not, the operator has access to the security code. LOCKED does allow access to the menus, but prevents changes to the parameters.

Whenever a locked function is attempted, the operator has the opportunity to enter a security code to override the lock. If the correct code is entered, the operator has full access. The security feature reactivates after one minute of keypad inactivity.

The operator also can enter the SECURITY OVERRIDE CODE, which, if entered correctly, resets the whole station to its default settings. The security override

code is 62647. Store this in a secure place. Refer to Chapter 2 for details on the Security Override function.

PROCESS VARIABLE READING CORRECTION

Under certain extraneous conditions — such as an aging thermocouple, out of calibration transmitter, lead wire resistance — the station may display values other than the actual process value. To compensate for these conditions, you can set offset and gain values for the process variable.

1. Press FAST + MENU to toggle to the PV INPUT menu. Press MENU to access

▲▲

each of the following parameters, and the

▼▼

▲ and

▼ keys to set values for

▲▲

▼▼

them.

2. PV OFFSET This either adds or subtracts a set value from the process variable reading

in engineering units. For example, if your thermocouple was always reading 3° too high, you could set the PV OFFSET parameter to –3 to compensate.

3. PV GAIN Multiplies the deviation from the low end of the process variable range by the

gain factor and then adds it to the value of the low end of the range to arrive at the adjusted process variable value.

For example, if your process variable range is 50 to 650 and the process variable reading is 472, a PV GAIN of 0.995 would yield an adjusted process variable equal to [(472 – 50) x. 995] + 50 = 470.

By using a combination of both offset and gain factors, you should be able to compensate for just about any inaccuracy in your sensor or transmitter.

with a supervisory device, such as a personal computer or programmable logic controller. The circuitry for communications is contained on a modular circuit board that plugs into the Microcontroller Circuit Board.

The station uses communications standard RS-485, which provides a multi-drop system that communicates at a high rate over long distances. Typical limitations are 32 stations per pair of wires over a distance up to 4000 feet.

The station uses a proprietary protocol which provides an extremely fast and accurate response to any command. A Cyclic Redundancy Checksum (CRC) can be enabled to ensure the integrity of any data read by the controller. Through communications, you have access to every set up and operating parameter in the station.

2. STATION Specifies the unit’s station address. It is the only way one controller can be

distinguished from another. Each controller on the same RS-485 interface must have a unique station address.

3. BAUD RATE Choose a baud rate from 1200 to 19,200. In general, you want to select the

highest baud rate. However, every station on the RS-485 interface must be set to the same baud rate.

4. CRC Indicates if you are going to take advantage of the Cyclic Redundancy

Checksum feature. If your host program supports it, we highly recommend that you activate it.

NOTE: The Process Variable Reading

Correction feature is provided only as a convenience. The condition

causing the erroneous reading should be corrected!

NOTE:

PV GAIN is only available if using a linear voltage or current input.

• Thermocouple Cold Junction Compensation

• Milliamp Output (Standard on 531). Access these parts of the calibration menu as shown in Figure D.1.

REGARDING CALIBRA TION

To maintain optimum performance, once a year calibrate the analog input, cold junction (when a thermocouple is used) and mA Output (when used). To achieve published accuracy specifications, follow directions carefully and use calibrated instruments of like quality to those suggested. Also, if you move a station chassis into an alternate case or change its hardware configuration, and you choose to use thermocouple input, you may want to recalibrate the cold junction for optimal accuracy. Failure to do so may result in small junction temperature (not more than 0.6°C/1.1°F).

If calibration is complete, place all the jumpers back in their original positions (as specified in Chapter 4).

Thermocouple Cold Junction Calibration

1. Add the T/C wires to terminals 31 and 32 as shown in Figure D.3a. The hook up wire connects to the multimeter. As was set for input calibration, set the meter for DC volts. Make sure the T/C wires are not connected to anything and are not touching each other.

2. Turn on power to the unit and let controller warm up for 30 minutes in the normal horizontal position: while the unit is warming up, the rear face of the controller should be vertical, not horizontal.

3. Press the MENU key until the display indicates “CALIBRATE COLD JUNC.”

4. Press the ACK key. The display should show “BASE VOLT 50.000” .

5. Connect T-Type thermocouple –150°C thermocouple calibrator to thermocouple wires on PV terminals.

6. Disconnect the hook up wires from the PV rear terminals (31 and 32) to the multimeter. Connect the thermocouple wires to the thermocouple calibrator instrument. Connect the meter test leads to the small hoops on terminals 23– and 24+ (see Figure D.4).

7. The 2nd display should show BASE VOLT. and the 3rd display should show a value close to 50.000.

8. Press s and t keys to match the controller display with the multimeter's display. Be sure that the multimeter's value is not drifting; wait until it is stable before pressing s and t keys to adjust controller display (the FAST key is active if you want to scroll through the numbers more quickly). When the value displayed on the controller matches the value on the meter, press the MENU key.

9. Disconnect the meter leads from terminals 23 and 24, and press the ACK key.

10.Test the thermocouple input to see if it is within ±1°F.

11.If you will be calibrating the milliamp output, move on to the Millamp Output Calibration, #5, where steps 1–4 can be skipped and only 10 minutes of warm up is required before proceeding to step 5.

If calibration is complete, power down, then place all the jumpers in their original positions (as specified in Chapter 4).

MILLIAMP OUTPUT CALIBRA TION

Once a year, calibrate the mA output to maintain optimal performance. Additionally, you should calibrate an output when a new mA module is installed.

The 531 local output should be calibrated at terminals 5 and 6 (OUT2– and OUT2+). The bypass circuitry PC board does not have to be removed to perform the calibration.

Equipment:

• Precision 5-1/2 or 6-1/2 digit multimeter, such as a Fluke 8842® or

Hewlett Packard HP3478A

• Two small pieces of wire for each milliamp output

• Test leads with clip ends

• #2 Phillips screwdriver

1. Disconnect power to the instrument.

2. Remove chassis from case.

3. Locate jumpers marked PV 1 and 2nd near the edge connector of the Microcontroller Board (refer to Figure D.2). Relocate both jumper connectors so that one is positioned on the pins marked V of the 2nd jumper and the other on the pins marked TC

4. Connect the small pieces of wire to the terminals assigned to the milliamp output(s) you are calibrating. Figure D.5 shows the hook up wires applied to OUT2+ and OUT2–. Hook up wires need to be applied to all terminals that have corresponding milliamp output modules in their output sockets. Attach the test leads from the multimeter to the wires, and then plug the test leads into the meter. Set the meter for DC milliamps.

5. Reinsert chassis into the case and apply power. The 2nd display should read CALIBRATE while the 3rd display reads ANLG. IN. Press MENU twice to get to the ANLG. OUT Menu.

6. Press ACK. The 2nd display will read OUTPUT 2.

7. The 3rd display should read 4 mA. Your meter should read a value close to 4.00 mA. Wait one minute. Then press and the meter’s display reads 4.00 mA. You may press FAST with key to change the value at a faster rate.

8. Press MENU. The 3rd display should read 20 mA. Let this setting stabilize for one minute. Repeat the procedure from Step 7.

9. To complete calibration, press ACK, and disconnect the power. Remove the station from its case, and place the jumpers in their correct operating positions (as specified in Chapter 4).

You must press the ACK key at the end of any calibration procedure to return to the calibration menu before powering down.

CALIBRATION

• To maintain optimum performance, once a year calibrate the analog input, the cold junction and milliamp output (when used). To achieve published accuracy specifications, follow directions carefully and use calibrated instruments of like quality to those suggested.

• If the controller is moved into an alternate case, or the hardware configuration is changed, and the thermocouple input is needed, recalibrate the cold junction for maximum accuracy. Failure to do so may result in small junction temperature (0.6°C/1.1°F).

531

Access the parts of the calibration menu as shown in Figure D.1. ATTENTION! The 531 comes from the factory with one milliamp output module installed in position (output) 2 and relays in position (outputs) 3 and 4. These must not be modified. You may install a mechanical relay, solid state relay or DC logic module in position (output) 1 for alarm functions.
