GETTING STARTED

1. Install the control as described on page 5.

2. Wire your control following the instructions on pages 5-11. If you are using a two-

wire transmitter as an input, see the drawing and instructions on page 7. Option

wiring instructions are on pages 8-11. Option descriptions and specific instructions

start on page 19.

3. Most controls do not need many (if any) program changes to work on your process.

For best results when changing the programming, make all the necessary changes

in the Secure Menu (page 31) before making changes to the Secondary Menu (page

24). If error messages occur, check the Error Messages on page 41-43 for help.

Take the example of a Model 26010 that comes from the factory programmed for type J thermocouples. Suppose for this example you wish to change the input to a 100 ohm Platinum RTD and limit the set point range between 0° and 300°C.

First, enter the Secure menu by pressing and holding the UP ARROW & ENTER keys for 5 Seconds. Press the INDEX key until the display shows I n P and press the

DOWN ARROW until the display shows P38 5 . Don’t forget to press the ENTER

key to retain your setting.

Next, press the INDEX key to display U n i t . Press the DOWN ARROW until the display shows C. Press ENTER.

Next, press the INDEX key until S P L is displayed (pass the dP t , I n P t , and S E n C selections). Press the UP ARROW until the display shows 0. Press ENTER.

Finally, press INDEX key to display S P H . Press the DOWN ARROW until the display shows 3 0 0 . Press ENTER.

The necessary program changes are now complete. After 30 seconds the display will switch back to the temperature reading. If you want to return faster, press the

UP ARROW & ENTER keys (at the same time) and then press the DOWN ARROW & INDEX keys (again at the same time). This will ‘back out’ of the menu and

immediately display the temperature reading.

If you want to use Self Tune

, Auto/Manual, or the Ramp/Soak Programmer features, see the special sections on these items. Page numbers for these are in the Contents section on the previous page.

PANEL

Mount the instrument in a location that will not be subject to excessive temperature, shock, or vibration. All models are designed for mounting in an enclosed panel.

Select the position desired for the instrument on the panel. If more than one instrument is required, maintain the minimum of spacing requirements as shown on the drawing below. Closer spacing will structurally weaken the panel, and invalidate the IP66, UL type 4X rating of the panel.

Prepare the panel by cutting and deburring the required opening.

PANEL CUTOUT

From the front of the panel, slide the housing through the cut out. The housing gasket should be against the housing flange before installing.

From the rear of the panel slide the mounting collar over the housing. Hold the housing with one hand and using the other hand, push the collar evenly against the panel until the spring loops are slightly compressed. The ratchets will hold the mounting collar and housing in place.

CAUTION: It is not necessary to remove the instrument chassis from the housing for installation. If the instrument chassis is removed from the housing, you must follow industry standard practice for control and protection against Electro-Static Discharge (ESD). Failure to exercise good ESD practices may cause damage to the instrument.

WIRING

Do not run RTD, thermocouple, or other class 2 wiring in the same conduit as power leads. Use only the type of thermocouple or RTD probe for which the control has been programmed. Maintain separation between wiring of sensor, optional inputs and outputs and other wiring. See the “Secure Menu” for input selection.

For thermocouple input always use extension leads of the same type designated for your thermocouple.

May, 2013 Page 5 of 52 949-1194 Rev. 7

www.GlobalTestSupply.com

For supply connections use No. 16 AWG or larger wires rated for at least 75°C. Use copper conductors only. All line voltage output circuits must have a common disconnect and be connected to the same pole of the disconnect.

Input wiring for thermocouple, current, and RTD; and output wiring for current and 15 VDC is rated CLASS 2.

Control wiring is as shown (view is from rear of instrument showing wiring terminals).

Note: Illustrations shown inside the wiring terminals represent internal circuitry. See next page for output wiring chart.

NOTATION CONVENTIONS FOR THE MENUS

Because of the number of features available in this control, information is included that may not apply to your specific control. All usable features are included in this book, but may not be used in your process. To increase clarity the following conventions are used:

1. Certain features, menu items, and functions shown in this book may or may not appear on your control, depending on other menu item selections. At various places in the menus there are notes identifying menu items that “control” or “direct” other menu items. If you are looking for a particular menu item and can’t find it, check the menu item that is its “control” for proper setting.

2. The “#” symbol is used in two ways. It is used inside a group of characters to indicate which set point function (S P 1 or SP 2 ) is being affected. It is also used before a group of characters of a menu item to indicate that there may be more than one selection or value for that menu item. This is used for certain repeated items such as in the Ramp/Soak Program section.

DISPLAY CONVENTIONS

The instrument front has two four digit displays, eleven indicators, and six keys. The diagram on page 12 shows the location of the displays and descriptors.

During normal operation the top four digit display indicates the temperature that is being read by the sensor. The bottom display indicates the set point. When you are programming the instrument, the bottom display indicates the Menu Item being programmed and the top display the value selected for that Menu Item. Error messages use both the top and bottom displays to indicate a particular error.

Each character can only be displayed with seven light segments. Alphabet characters may look peculiar when seen presented this way. The following is an example of the ‘seven segment alphabet’ as used in the instrument:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

A b Cd EFGHIJKLmnO PQ rSt U V U XYZ

0 1 2 3 4 5 6 7 8 9

0 1 2 3 4 567 8 9

Notice that some characters are in upper case while others are in lower case. Some look the same (e.g. G [G] and 9 [9 ]) and must be interpreted by context. Others are close (e.g. B [b ] and 6 [6 ]), but different. Usually, the context of the term or value will help you determine the correct character.

May, 2013 Page 14 of 52 949-1194 Rev. 7

www.GlobalTestSupply.com

THE HOME DISPLAY

The home display is the normal display while the control is operating. If no errors or functions are active, the HOME display will indicate the Process Variable (the temperature, pressure, flow, RH, etc., that is being measured) on the top display and the Set Variable (Set Point 1) on the bottom.

Items that can change the HOME display are the Auto/Manual function, the Run/Hold function, the P r o 9 function, the P c t O function, and any error message. Description of these special displays follows.

If the Auto/Manual key is pressed, the Manual indicator lights, the “%” indicator lights, and the home display is changed. The upper display continues to show the Process Variable (PV), but the lower display changes to show the percentage of output in tenths of a percent to 99.9% (0.0 to 99.9), or 100 if 100%. The display digit to the right of the number shows a flashing letter o to indicate that the value displayed is no longer the SV, but percent output. The SP 2 percent output is indicated by the use of an overline on the letter õ. Access to the SP 2 value is made by the INDEX key. See Auto/Manual Operation on Page 17 for further information.

If P r o 9 is turned O n , the HOME display changes the SV display from S P 1 to the Present Set Variable as calculated by the Ramp/Soak Programmer function. See Programming and Operation for Ramp/Soak Feature below for more information.

If P c t O (Secondary Menu) is turned O n , the lower display changes to show the active percentage of output as required to maintain S P 1 . The display is similar to the Auto/Manual display above, except that the percent indicators (o ,õ ) do not flash, and the output is displayed in whole percentages of output, not in tenths of a percent. If the control has both S P 1 and SP 2 , the lower display will alternate between the S P 1 percent output and the SP2 percent output.

Error messages are listed on pages 41-43.

PROGRAMMING AND OPERATION FOR RAMP / SOAK FEATURE

The ramp / soak feature offers a great deal of flexibility by allowing changes in the set point to be made over a predetermined period of time. Dwell times can be programmed, and the alarm output relay can be programmed to open or close during any of the segments.

Theory of Operation

The 2600 Series controls offer a very simple approach to programming a ramp. Rather than requiring the operator to calculate an approach rate (usually in degrees per minute), the 2600 does the calculation internally. Thus, the operator only needs to program the target set point and the time desired to reach that point. When the ramp segment is executed by the control, it calculates the ramp required to move the process from the starting value (current PV) to the desired value (programmed SP) in the time allowed.

May, 2013 Page 15 of 52 949-1194 Rev. 7

www.GlobalTestSupply.com

Soaks (or dwells) are ramp segments where the target set point is the same as the beginning process value. This allows for multistage ramps without wasting intermediate soak steps. Care must be taken, however, that the process does actually reach the soak value before the soak time starts. If not, the next segment will calculate a slope from the starting PV to the target SP. Depending on your process requirements, this difference may be important. Make sure to test any program for desired results before running production material.

Do not operate Self Tune while a ramp function is operating. The ramp function will prevent the Self Tune from operating properly. Make sure that all tuning is set up before operating Ramp / Soak.

Program Setup

All of the programming for the Ramp / Soak function is done in the Secondary Menu. You may wish to work out your program on paper before going into the programmer menu sequence.

In the Secondary Menu INDEX to P r o 9 and make sure that P r o 9 is set to O F F .

INDEX to P S E t and turn O n . Press ENTER.

Skip the S t A t setting (this is discussed later) and press INDEX to 1 t i .

The following items repeat in the following order: 1 t i , 1 S P , 1 A 1 and/or 1A2 (if AL 1 or AL2 in the Secure Menu are programmed set to E U n t ), 2 t i , 2 S P , 2 A 1 ,..., 1 6 t i , 1 6 S P , 1 6 A 1 , 1 6 A 2 . To avoid repetition each item will only be described once.

Set 1 t i to the amount of time you want for the first ramp. This value is in time units (determined by the t b A S menu item) from 0 to 999 9 . Press ENTER.

Set 1 S P to the target value desired for the first ramp. This value is in actual units just like S P 1 . If the control is programmed for temperature, then the SP displays are in temperature. If the control is programmed for some other engineering unit, the SP is set in that unit.

Press INDEX to continue. If Alarm 1 is programmed as an event (AL 1 = EUn t ), then 1 A 1 will appear. If you wish the Alarm 1 contact to function for this segment, set 1 A 1 for On . If not, set for O F F . Press ENTER. When 1 A 1 is set to On, the Alarm 1 function will be active for the entire period set in 1 t i above.

Complete setting the segment times (2 t i ... 16 t i ), segment set points (2 S P ... 1 6 S P ), and event alarms (2 A 1 ... 16 A 1 ) to O n or OFF .

For unneeded or unused segments set the segment times (2 t i ... 1 6 t i ) to 0 , and set the segment set points (2 S P ... 16 S P ) to the same value as the last active set point. A segment alarm may be set to indicate “end of run” at the segment number you select.

The last menu item for the ramp / soak function is P E n d . P E n d determines what the control does when the program has ended. You may choose to have the program repeat (L o o P ), H o l d the last set point (1 6 S P ), revert to the local S P 1 , or turn the outputs off (O o F F ).

It is important to remember that if you want the program to repeat, you must allow the process to return to the same condition that existed when the program first started. Remember that the ramp function calculates the slope by drawing a line from the beginning PV to the ramp target set point. If the PV at the end of the program is different than the PV at the initial start, the ramp will calculate differently.

Ramp / Soak Operation

When you wish to start the program, enter the Secondary Menu and set the P r o 9 menu item to O n . Return to the HOME position by waiting for the display to time out or by pressing the UP ARROW & ENTER keys and then the DOWN ARROW & INDEX keys.

The home display will read as it normally does. The HOLD indicator by the RUN / HOLD key will be lit. To start the program press the RUN / HOLD key for three seconds. The HOLD indicator will go out, and the program will start.

To suspend the program at any time, press the RUN / HOLD key. Press the key again to resume.

Pressing the AUTO / MANUAL key will also suspend the program operation. The difference is that AUTO / MANUAL also puts the control into manual mode. See Auto / Manual Operation on page 18.

The function of the Primary Menu will change depending on the setting of the S t A t menu item in the Secondary Menu. If S t A t is O F F then the Primary Menu is not changed.

If the S t A t menu item is set to O n , then the Primary Menu has three additional information items added before S P 1 appears. The first INDEX item displays the time remaining in the current segment in the top display (####), and the message t i , in the lower display. The next INDEX item displays the total time for the active segment in the upper display (####) and the message ##t i (1t i ...1 6 t i ), in the lower display. The third INDEX item displays the segment set value (####) in the top display, and the message ##S P (1SP ...1 6 S P ) in the lower display. The next INDEX press resumes the normal Primary Menu

AUTO / MANUAL OPERATION

The AUTO / MANUAL function allows you to manually adjust the output of the control. This is normally used during process setup or start up. It can also be used for troubleshooting. To switch from AUTO to MANUAL press the AUTO / MANUAL key and hold for three seconds. The MANual indicator will light and the lower display will change from normal to showing the actual output in percent. The value will be the actual percentage of output that was active when the key was pressed. This is usually known as “bumpless transfer”.

If you wish to change the output while in manual, press the UP ARROW or DOWN ARROW keys to change the value, and press ENTER to retain it. It is important to remember that the value of the display is read as 0 to 100% of the full control output, NOT the range between S1OL and S1OH or S2OL and S2OH. For example, if the set point one output is programmed for 4 to 20 mA (S1OL=20, S1OH=100), a reading of 50% in MANUAL represents 10 mA, not 12 mA. This allows the operator to go above and below the output range to allow for improperly function equipment that may be connected to the control output.

To return to AUTOmatic control, press the AUTO / MANUAL key again. The MANual indicator will go out, and the set point will take over. However, if you want bumpless transfer back to AUTO, slowly change the percentage of output until the process variable matches (or at least is close) to the set point. The further away the PV is from the set point, the greater the “bump” or upset there will be in the output.

SELF TUNE FUNCTION

Self Tune allows automatic selection of the necessary parameters to achieve best control operation from your 2600 Series control. If you are using the control output as a simple on-off function (Ou t 1 set for O n O F ), none of the following will apply.

Theory of Operation

The Self Tune function calculates the Pb 1 , r E S , and r t E parameters under the P i d t u n E selection, and the F b n d and F r t E parameters, as shown in the Secondary Menu. These values are determined by measuring the response of the process connected to the control. When Self Tune is started, the control temporarily acts as an on-off control. While in this mode the control measures the overshoot and undershoot of the process, and the period of the process (the time from peak value to the next peak value). These measurements are collected over a period that lasts three periods of overshoot and undershoot. The data collected over this time is then compared and calculated into final PID and Fuzzy Logic values. The effect of Fuzzy Logic on the process is still controlled by the F i n t (fuzzy intensity) setting. If F i n t is 0 , the F b n d and Fr t E will be calculated, but will have no effect. The calculations for the PID values are the same as used in the standard Ziegler - Nichols equations that have been recognized as standard for decades.

The only modification to the application of the Ziegler - Nichols equations is controlled by the d F A C menu item. This menu item controls the amount of rate (derivative) that is applied. A d F A C setting of 3 (factory default) or less allows for less damping. A d F A C setting of 4 allows for critical damping as set forth in Ziegler - Nichols. A d F A C setting of 5 or more allows over damping of the process.

Program Setup and Operation

Do not cool the process or add heat while the tuning is occurring. In the secondary menu set t u n E to S E L F . Skip L E r n and check to make sure that d F A C is set to the desired value. Back up to L E r n and set to Y E S . The control will begin the Self Tune function. While the Self Tune function is active, the right hand decimal point on the lower display will blink. When Self Tune is complete, the blinking will stop.

After Self Tune is complete, the tu n E setting automatically switches to Pi d . This allows examination and / or modification of the values calculated. We recommend that you do not change the calculated values unless you have a firm understanding of the parameters involved and their function.

OPERATION AND PROGRAMMING OF OPTIONS

Options 924, 926, 928, Analog Remote Set Point

The analog remote set point allows the control set point to be determined by an outside analog signal. The signal may be 0 to 10 VDC (Option 924), 0 (or 4) to 20 mADC (Option

926), or 0 to 10,000 Ohms (Option 928).

Wire the input as shown on pages 8 and 9.

To set up the analog remote set point, first determine the scale range that the analog signal will represent. The maximum span is 11,998 degrees or counts. In the Secure Menu set r S C L for the scale value that will be represented by the low end of the analog signal (0 Volts, 0 mA, 0 Ohms). Set rS C H for the scale value that will be represented by the high end of the analog signal (10 Volts, 20 mA, 10,000 Ohms).

If you require a suppressed scale or input, use the following equations to determine the proper settings for r S C L and r S C H .

K = (Highest desired scale reading - Lowest desired scale reading) / (Maximum desired analog signal - Minimum desired analog signal). r S C H = ((Maximum possible analog signal- Maximum desired analog signal) * K) + Highest desired analog reading. r S C L = Lowest desired scale reading - ((Minimum desired analog signal) * K).

Make sure that a valid analog signal is available to the control. In the Secondary Menu set the r S P t to O n . The REM indicator on the front of the control will turn on. When the control returns to the HOME position, the displayed SV will be the value supplied from the analog remote signal. If the analog remote signal fails or goes out of range of the S P L or S P H settings, the control will revert to the internal S P 1 (or #S P 1 ), and flash the error message C H E C r S P t . If S P L or S P H are set outside of rS C L or rS C H then the error will be suppressed, and the control will attempt to work with the remote value.

To clear the error message, change r S P t to O F F .

Option 934, 936, Isolated Analog Retransmission.

The analog retransmission option allows the Process Variable or the Set Variable to be sent as an analog signal to an external device. The signal may be either 0 to 10 VDC (Option 936) or 0 (or 4) to 20 mADC (Option 934). The output may be changed in the field from one to the other by the toggle switch located on the top printed circuit board.

Wire the output as shown on page 9.

To set up the analog retransmission, first determine the scale range that the analog signal will represent. The maximum scale is 9999°F, 5530°C, or 9999 counts. In the Secondary Menu set P O L for the scale value that will be represented by the low end of the analog signal (0 Volts or 0 mA). Set PO H for the scale value that will be represented by the high end of the analog signal (10 Volts or 20 mA).

If you require a suppressed scale or output, use the following equations to determine the proper settings for P O L and PO H .

K = (Highest desired scale reading - Lowest desired scale reading) / (Maximum desired analog signal - Minimum desired analog signal). P O H = ((Maximum possible analog output - Maximum desired analog signal) * K) + Highest desired analog reading. P O L = Lowest desired scale reading - ((Minimum desired analog output) * K).

Next select whether you want the retransmission signal to follow the Process Variable or the Set Variable. Usually the Process Variable is sent to recorders or other data acquisition devices. Usually the Set Variable is sent to other controls to be used as an analog remote set point. If you want the analog retransmission signal to follow the PV, in the Secondary Menu set P O S r to I n P . If you want the analog retransmission signal to follow the SV, set P O S r to SPt .

Operation is automatic. There are no further programming steps required.

Option 948, 4-Stage Set Point.

The 4-stage set point option allows four different values to be used for SP 1 and all of the values associated with the t u n E menu items. The control will switch to a given stage when an external contact or contacts are made or opened across the appropriate terminals at the rear of the control (S P S A , Set Point Switch Action, set for remote, rE ), or when the stage is selected from the Secondary Menu, S P (when SP S A is set for In t ). When the state of a contact changes (or the stage number is changed in the Secondary Menu), the values in use are stored and the previously stored values for the new stage are used.

Wire the input as shown on page 10.

Usually the control is configured for external switching of the stages. In this case, the operation is usually automatic, selected by the external switches driven by the machine logic. If it is necessary to program the stages in advance, you may select the stage to modify with the S P menu item. When SP is changed while the SP S A is set for rE , the selected stage is displayed for modification, but only used when the appropriate contact is made.

Option 992, 993, 995, 996 Serial Communication.

The serial communications options allow the control to be written to and read from a remote computer or other similar digital device. Communication is allowed either through a RS-485 (Option 992, 996) port, or a RS-232 (Option 993, 995) port.

Wire the communication lines as shown on Page 11. Wiring for the RS-485 is run from control to control in a daisy chain fashion with a termination resistor (120 ohms) across the transmit and receive terminals of the last control in the chain.

Select the control address and communication baud rate with the A d d r and b A U d menu items in the Secure Menu.

NOTE: THE BAUD RATE AND ADDRESS MENU ITEM SETTINGS WILL TAKE EFFECT ON THE NEXT POWER UP OF THE CONTROL. BE SURE TO TURN THE POWER TO THE CONTROL OFF AND ON BEFORE USING THE NEW BAUD RATE AND ADDRESS VALUES.

In operation, you have the option of preventing a write command from the host computer. To prevent the host from writing to the control change the L O r E menu item in the Secondary Menu to L O C . To allow the host to write commands to the control set LO r E to r E . (The host does have the ability to change the L O r E state, but it is not automatic.)

If your system depends on constant reading or writing to and from the host, you may wish to set the No Activity Timer (n A t ) to monitor the addressing of the control. When the L O r E is set to r E and the nAt is set to any value other than OFF , the control will expect to be addressed on a regular basis. If the control is not addressed in the time set by the value of n A t , then the control will display the error message C H E C L O r E . To clear the message set L O r E to L O C .

SERIAL COMMUNICATIONS OPTIONS AND NONVOLATILE MEMORY

There are many different types of memory used in computer driven devices. The terms RAM (random access memory) and ROM (read only memory) are a couple with which you may be familiar.

RAM is used in computers to run programs and hold data for a short period of time. This is the memory that is used primarily in PCs. RAM is very fast and can be read and written to over and over again. Its major weakness is that it is erased when the power is turned off.

ROM is used in computers to hold the ‘permanent’ programming that allows a PC to start. This memory is ‘burned in’ to the chip itself and can not be changed. Unlike RAM, however, this memory is permanent. While it can not be changed, it can not lose its programming when power is turned off. This is the type of memory that is used to store the permanent programming for the control.

There is a third type of memory that is now currently used to combine the characteristics of both RAM and ROM. This is known as EEPROM (electrically erasable programmable read only memory). While the name may be long and somewhat cryptic, the EEPROM can be erased and re-written many times, and yet hold the programmed data even over long periods when the power is off. This is the type of memory that Love Controls uses to save the settings you program in your control. The reliability and longevity of the data retention is what allows us to guarantee a 10 year data retention without power.

In normal operation, the control uses RAM, just as any other computerized device. Whenever you make a change to one of the parameters in the control, the set point for example, the new value is written into the EEPROM. This way, if power goes off for whatever reason, when power resumes, the latest settings are preserved. When power is turned on, the data is copied from the EEPROM to the RAM to restore operation.

You might ask, “If EEPROM is such a wonderful thing, why bother with RAM?” One reason is that is that RAM is much faster than EEPROM. Faster speed gives you better performance in critical control functions.

Perhaps the most important reason is that RAM allows an unlimited number of writes, while EEPROM has a limit to the number of times that it can be erased and re-written. Current technology now sets that limit at about one million erase / write cycles. In a dynamic control situation, it may be necessary to update RAM every few milliseconds. EEPROM can not keep up to that pace, and, even if it could, it would be ‘used up’ in a matter of days.

If you think about how long it would take to make a million changes to the control programming through the front key pad, you will see that it would take a very long time to get to use up the life of the EEPROM.

Adding one of the computer communications options (e.g. 992, 993, 995, 996) changes the picture. The speed of computer communications is such that hundreds of instructions can be made in less than a minute. In such a situation, the million erase / write cycles could be used up in a couple of months causing the chip (and the control) to fail.

Usually in such a situation, the control is under close observation by the host computer. It may not be necessary, then, to have the data written to the EEPROM, as it is ‘transitory’ in nature (changing set points for a ramp/soak sequence for example).

Controls equipped with a Serial communications option have a menu item in the Secure menu (S t o r ) that allows the serial communications to write to RAM (S t o r = n o ).

The factory default is ‘write to EEPROM’ (Sto r = Y E S ).

If your computer system will be making frequent changes to the control, we strongly recommend that you select the ‘write to RAM’ parameter (Sto r = no ). If you are primarily reading from the control, there is no need to change the setting.

For further information on protocols and technical information regarding computer programming for the Serial Communications options, see our web site at http://www.lovecontrols.com/protocol.

ALARM TYPE AND ACTION (if alarm function is present)

Caution: In any critical application where failure could cause expensive product loss or endanger personal safety, a redundant limit controller is required.

When setting an alarm value for an absolute alarm (A 1 t = A b S ), simply set the value at which the alarm is to occur.

When setting the alarm value for a deviation alarm (A 1 t = d E ), set the difference in value from the Set Point desired. For example if a low alarm is required to be 5 degrees below the Set Point, then set A 1 L o to -5. If a high alarm is required 20 degrees above the Set Point, then set A 1 H i to +2 0 . If the Set Point is changed, the alarm will continue to hold the same relationship as originally set.

www.GlobalTestSupply.com

The diagram below shows the action and reset functions for both absolute and deviation alarms.

D = 1 degree F, 1 degree C, or 1 count.

Note that when Alarm Power Interrupt, A1 P i , is programmed O n and Alarm Reset, A1r E , is programmed for H o l d , the alarm will automatically reset upon a power failure and subsequent restoration if no alarm condition is present.

If Alarm Inhibit, A1 i H , is selected O n , an alarm condition is suspended upon power up until the process value passes through the alarm set point once. Alarm inhibit can be restored as if a power up took place by pressing both the INDEX & ENTER keys for 3 seconds.

WARNING: IF INHIBIT IS ON AND A POWER FAILURE OCCURS DURING A HIGH ALARM, RESTORATION OF POWER WILL NOT CAUSE THE ALARM TO OCCUR IF THE PROCESS VALUE DOES NOT FIRST DROP BELOW THE HIGH ALARM SETTING. DO NOT USE THE ALARM INHIBIT FEATURE IF A HAZARD IS CREATED BY THIS ACTION. BE SURE TO TEST ALL COMBINATIONS OF HIGH AND LOW ALARM INHIBIT ACTIONS BEFORE PLACING CONTROL INTO OPERATION.

Meaning

Display is blank. Instrument is not getting power, or the supply voltage is too low.

Fail test appears upon power up if the internal diagnostics detect a failure. This message may occur during operation if a failure is detected. Displays flash. Fail test may also occur due to an EEPROM failure. This message will appear upon power up if S P 1 , S P 2 ,#S P 1 , or # # S P is set outside of the S P L or SP H values.

This message appears at power up if S P L or SP H values are programmed outside the input range ends. This message appears if the analog remote set point signal is out of range. This message appears if the Serial Communications has timed out.

SP Outputs

Action Required

Check that the power supply is on, measure supply voltage, check that the external fuses are good.

The display alternates between F A I L t E S t and one of the following messages: F A C t d F L t : Memory may be corrupted. Press the DOWN ARROW & ENTER keys to return control to the factory default settings. Recheck controller programming. r E t F A C t : Unrecoverable error, return to factory for service.

Correct the S P 1 , etc. or adjust the S P L or SP H values by programming new values.

Correct the S P L or SP H values by programming new values.

The control will revert to S P 1 . Correction of the analog signal or turning O F F the rS P t clears the error message. Change the L o r E to L O C . Restore the communications line and switch L o r E back to r E .

CONFIGURATION MENU

DO NOT ENTER THE CONFIGURATION MENU UNLESS YOU HAVE BEEN INSTRUCTED TO BY THESE INSTRUCTIONS. INCORRECT ENTRY OF DATA IN THE CONFIGURATION MENU MAY CAUSE IMPROPER OR UNPREDICTABLE OPERATION OF THE INSTRUMENT.

The Configuration Menu is used to quickly recover the instrument after certain Error Codes. The configuration for your particular model is shown on the Model / Serial label located on the left side (when viewed from the front) of the instrument housing. A label found inside on the right side of the chassis shows the same information.

If you do recover the instrument from a F A i L t E S t error, the memory configuration is restored to the factory settings. All hardware inputs and outputs are automatically recognized except for Options 924, 926, and 928.

If you have a instrument equipped with one of these options, Factory Default will not automatically restore these settings. They must be set by hand.

To re-configure:

1. At power up, simultaneously press and hold the INDEX & ENTER keys while the lamp test or self test is displayed. Hold the keys down until the ROM ID code appears.

2. Press the INDEX key to advance to the next menu item, F A C t d F L t . This function restores the control to original factory settings. It will also remove all of the hardware, option, and software configuration values. After selecting FA C t d F L t you will need to restore the configuration values as shown above to allow the instrument to operate correctly.

To restore factory default values, press and hold the ENTER key. While holding the ENTER key also press the DOWN ARROW key. The display will blink momentarily and the instrument will reboot. The instrument will then display the ROM ID. Press INDEX to step through F A C t d F L t and continue at step 3.

3. Press INDEX to OPt1 . If your instrument is equipped with Option 924, 926, or 928, press the UP ARROW or DOWN ARROW as necessary to display r S P t . The display will be flashing. To select, press ENTER while r S P t is displayed. When selected, the option number will stop flashing.

DO NOT SELECT AN OPTION IF THE INSTRUMENT DOES NOT HAVE THE HARDWARE TO SUPPORT IT. SELECTION OF AN UNSUPPORTED OPTION MAY CAUSE IMPROPER OR UNPREDICTABLE OPERATION OF THE INSTRUMENT.
