1.2 Displays
Each instrument is provided with two main displays, a message display, and status indicators as shown in Figure 1 -1. The upper main display shows the value of the process variable. The lower main display shows the setpoint value. The message display shows parameter tag names and mode list items during various modes of operation.
1.3 Control
The instrument can be programmed for on-off, time proportioning, or current proportioning control implementations depending on the model number. A second control output is an available option. Proportional control implementations are provided with fully programmable PID parameters. In addition, setpoint programming is available to step the controller through ramp and soak segments.
1.4 Alarms
Alarm indication is standard on all instruments. Up to two alarm outputs are possible. Alarm type may be set as Process Direct or Reverse (high or low), Deviation Direct or Reverse (above or below setpoint), Deviation Band Type (closed or open within band), or Loop Reverse or Direct. Alarm status is indicated by LED. An Alarm Inhibit is provided to prevent, when activated, unwanted alarms during power-up.
1.5 Re-Transmission (Analog) Output
If the instrument is specified with this option, the process variable or setpoint value can be scaled over any desired range and re-transmitted
1.6 Remote Inputs
The optional remote inputs allow for external selection of a profile; profile start; hold; or reset; and for selection of profile timebase.

SECTION 2: INSTALLATION & WIRING
2.1 Unpacking Procedure
1. Remove the instrument from its packing. The instrument is supplied with a panel
gasket and push-fit strap. Retain the packing for future use, should it be necessary to transport the instrument to a different site or return it to the factory for repair/testing.
2. Examine the delivered items for damage or deficiencies. If any is found, notify the
carrier immediately. Check that the model number shown on the label affixed to the instrument housing corresponds to that ordered (see Appendix D).
2.2 Panel-Mounting The Setpoint Programmer
The panel on which the instrument is to be mounted must be rigid and may be up to 6.0 mm (.25 inches ) thick. The cutout required for a single instrument is shown in Figure 2-1.
FIGURE 2-1 Cut-Out Dimensions
5
The main dimensions of the instrument are shown below. FIGURE 2-2
Main Dimensions
To panel-mount the instrument:
1. Insert the rear of the instrument housing through the cutout (from the front of the
mounting panel) and hold the instrument lightly in position against the panel. Ensure that the panel gasket is not distorted and that the instrument is positioned squarely against the mounting panel. Apply pressure to the front panel bezel only.
Caution: Do not remove the panel gasket, as this may result in inadequate clamping of the instrument in the panel.
2. Slide the fixing strap in place (Figure 2-3) and push it forward until it is firmly in
contact with the rear face of the mounting panel (the tongues on the strap should have engaged in matching ratchet positions on the instrument housing and the fixing strap springs should be pushing firmly against the mounting panel rear face).
Once the instrument is installed in its mounting panel, it may be subsequently removed from its housing, if necessary, as described in Appendix B.

FIGURE 2-3 Panel-Mounting the Instrument
2.3 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.
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 device listed, the instructions below should be followed:
7
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. AC POWER WIRING Neutral (For 115 VAC) 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.
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)
SPDT Relays
SSR driver outputs
AC power
The only wires that should 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 wires. If wires must cross each other, do so at 90 degrees. This will minimize the contact with each other and reduces "cross talk". "Cross Talk" is due to the EMF (Electro Magnetic Flux) emitted by a wire as current passes through it. This EMF can be picked up by other wires running in the same bundle or conduit.
In applications where a High Voltage Transformer is used (i.e. ignition systems) the secondary of the transformer should be isolated from all other cables.
8
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 the source.
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.
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 (resistance­capacitance) 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 as possible to the coil. See Figure 2-4. Additional protection may be provided by adding an RC network across the MOV.
FIGURE 2-4
9
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 2-5, below.
FIGURE 2-5
2.4 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

2.5 Input Connections
In general, all wiring connections are made to the instrument after it is installed. Avoid electrical shock. AC power wiring must not be connected to the source distribution panel until all wiring connection procedures are completed.
Caution: This equipment is designed for installation in an enclosure which provide adequate protection against electric shock. Local regulations regarding electrical installation should be rigidly observed. Consideration should be given to prevention of access to the power terminations by unauthorized personnel. Power should be connected via a two pole isolating switch (preferably situated near the equipment) and a 1A fuse, as shown in Figure 2-7.
FIGURE 2-7 Line Supply
The instrument will operate on 90-264V AC 50/60 Hz electrical line supply. The power consumption is approximately 4 VA. If the instrument has relay outputs in which the contacts are to carry line voltage, it is recommended that the relay contact line supply should be switched and fused in a similar manner but should be separate from the instrument line supply.
13
FIGURE 2-7A 24V Nominal AC/DC Supply
The supply connection for the 24V AC/DC option of the instrument are as shown below. Power should be connected via a two pole isolating switch and a 315 mA slow-blow (anti-surge type T) fuse. With the 24V AC/DC supply option fitted, these terminals will accept the following supply voltage ranges:
24V (nominal) AC 50/6OHz - 20-50V
24V (nominal) DC - 22-65V
FIGURE 2-8 Thermocouple (T/C) Input

FIGURE 2-24 Remote Program Inputs (optional)
If the Remote Program Control Inputs has been specified, make connections as shown.
Note: Only one remote connection shown for clarity. Remote inputs may be used to control parameters normally operated via the keypad.
Remote inputs are operated by closing an external relay. R0, R1 and R2 form a three­bit digital representation of the desired profile, with R0 being the least significant bit. Closing the RESET input will cause a running profile to abort. Closing the RUN/HOLD relay will start a profile. Subsequently opening this contact will hold the profile at its current setting and closing it again will continue the profile. The X60 or JUMP input is configurable to cause either a change to the profile timebase (X60) or jump to the next segment (JUMP).

SECTION 3: OPERATION
3.1 Control Responses
Each instrument may be configured to provide three mode proportional control. Proportional control is provided with Proportional Band, Integration, and Derivative responses. The PID parameters are defined as follows:
Out 1 Out2 P (Proportional) Proportional Band Pb1 Pb2 I (integration) Automatic Reset ArSt ArSt D (Derivative) Rate rAtE rAtE
Manual Reset is provided for use in lieu of, or in conjunction with automatic reset. A cycle time adjustment parameter is provided for use with each time proportioning control output.
3.2 Direct/Reverse Operation of Outputs
Direct operation is typically used with cooling applications. On-Off direct output(s) will turn on when the process variable exceeds setpoint. Proportional direct output(s) will increase the percentage of output as the process value increases within the proportional band.
Reverse operation is typically used with heating applications. On-Off reverse output(s) will turn off when the process variable exceeds setpoint. Proportional reverse output(s) will decrease the percentage of output as the process value increases within the proportional band.
Output 2 will be Direct when Output 1 is selected as Reverse and Reverse when Output 1 is selected as Direct.
23
3.3 On-Off Control
On-Off control can be implemented with SPDT relay or SSR driver output(s) by setting the corresponding proportional band (Pb) to 0.0. On-Off operation can be assigned to Output 1 only (Output 2 not present), Output 1 AND Output 2, or Output 2 only (Output 1 is time proportional or current proportional). A hysteresis adjustment is provided for On-Off outputs, "HySl " for Output 1 only, "HySt" for Output 1 AND Output 2, or "HyS2" for Output 2 only. This adjustment is in % of input span and defines the bandwidth of the hysteresis. Relay chatter can be eliminated by proper adjustment of this parameter. When operating in On-Off control, the output(s) will turn on or off depending upon the setpoint, the process value, and the hysteresis adjustment.
3.4 Time Proportioning Control
Time Proportioning control can be implemented with a SPDT relay or SSR driver. Time proportioning control can be selected for either Output 1 or Output 1 and Output 2, depending on hardware configuration. Time proportioning control is accomplished by cycling the output on and off during a prescribed period of time when the process variable is within the proportional band.
Ex: Calculated output % = 40%; Cycle time adjustment = 32 seconds
Output on time =.4 x 32 = 12.8 seconds Output off time = .6 x 32 = 19.2 seconds
When the unit is operating in the Control Mode, the control algorithm determines the output % required to correct for any difference between the process value and the setpoint. The output calculation is affected by Tune Mode parameter adjustments. See Figure 3-1 for proportional bandwidth effect on the output.
3.5 Current Proportioning Control
Current Proportioning control can be implemented on units provided with mADC current output(s). Current Proportioning control provides a 4 to 20 mADC or 0-20 mADC output in response to process value and setpoint. As with Time proportioning, the calculated output % for Current proportioning is affected by the Tune Mode parameter adjustments.
See Figure 3-1 (below) for proportional bandwidth effect on the output.
24
FIGURE 3-1 Proportional Band 1
25
3.6 Power Up Procedure
Verify all electrical connections have been properly made before applying power to the instrument.
If the instrument is being powered for the first time, it may be desirable to disconnect the controller output connections. The instrument will be into control following the power up sequence and the output(s) may turn on. During Power up, a self-test procedure is initiated during which all LED segments in the two front panel displays appear and all LED indicators are on. When the self-test procedure is complete, the instrument reverts to normal operation.
Note: When power is first applied, a delay of approximately 3 seconds will be seen before the displays light up.
3.7 Keypad Operation

28
Mode Indicators
SET - On when Profile Set Mode is entered; flashes when viewing parameters in Configuration Mode after entry from Base Mode.
PRG - On when Profile Set Mode is entered.
3.9 Displays
29
3.10 Viewing Setpoint And Control Status
In Base Mode (with no program running), repeatedly pressing the SCROLL key will cause the control to display various control information. The operator may view and change the setpoint. The operator may also view the units the control is using, whether the outputs are on or off, the alarm status, the present time and day (if the real time clock is fitted), and the percent output of the control instrument (if operating in Manual Mode).
NOTE: If the SCROLL key is held for more than two seconds, the instrument will automatically scroll through the displays.
3.11 Viewing And Adjusting The Controller Setpoint
With the Setpoint Programmer in Base Mode (i.e. with the RUN, HLD, SET, and PRG indicators off), the two main displays will show the process variable value (upper display) and the setpoint value (lower display - Read Only). To change the setpoint value:
1. Press the SCROLL key until the Message Area displays Setpoint.
2. If Setpoint has been enabled in the Enable Mode, the UP and DOWN keys may be
used to change the setpoint value (in the lower display) as required.
3. When the setpoint value is set as desired, press the SCROLL key again to view
other Base Mode parameters.
3.12 Viewing The Input Units
To see what type of input the control is using press the SCROLL key until the Units display is shown. The Units display shows the temperature scale for thermocouple and RTD inputs <DEGF> or <DEGC> or unspecified engineering UNITS for other input types. This display can be deactivated, if desired.
30
3.13 Base Mode And Off Mode Outputs
The Base Mode allows for the process and event outputs to be turned on or off. When all outputs are off, the Base Mode becomes Off Mode. In Base Mode the process output is adjusted by the controller based on the process input and setpoint. The event outputs for the Base Mode are set in the Configuration Mode. To view the present status of the outputs, press the SCROLL key until OUTPUTS is displayed in the message display. Use the UP and DOWN keys to turn the outputs ON or OFF (toggle between Base Mode and Off Mode).
3.14 Alarm Status Indication
When any alarm is active, the ALM indicator will flash. To view the main status in the Message Display, press the SCROLL key until a display appears in the form:
3.15 Manual Control
In any mode except Configuration Mode, the operator may select manual control of the process by simultaneously pressing the SCROLL and MODE keys, provided Manual Mode is enabled in Enable Mode. The instrument will then enter Base Mode or (if a program is currently running) Program Run Mode with the program held. The Message Display will read Manual, the MAN indicator will be lit, and the lower Main Display will show the power output value, in format PXXX, which may then be adjusted using the UP and DOWN keys.
31
While manual control is being used, the power output display is included in the displays available in Base Mode and Program Run Mode. To view the percent output setting when the Manual Mode is active, press the SCROLL key until Manual is displayed. This display is not available if Manual Mode is not active.
To cancel manual control, press the SCROLL and MODE keys simultaneously, whereupon the power output value display and the Manual message display will disappear. The Setpoint Controller will remain in whatever mode prevailed when manual control was implemented (if this is Program Run Mode, the currently-running program will be resumed from the point at which it was held).
3.16 Viewing The Time And Day
If the real time clock option is fitted, the operator may view the present time and day. Press the SCROLL key until HH:MM Tim is displayed. This is the present time of day in hours and minutes. Press the SCROLL key again and Day: XXX is displayed with XXX being an abbreviation for the present day of the week. If TIME BAD is displayed, the time and day must be set in the Profile Mode (see Section 6).
3.17 Selecting And Running A Program
When no program is running, the instrument is in Base Mode and the RUN and HLD indicators are off. In this mode, select a program as follows:
1. Hold down the PROF key until the required program number is displayed.
2. Press the RUN/HOLD key once to start the program. The RUN indicator will then go
ON, or flash if a delayed start has been programmed. The instrument is now in
Program Run Mode. In Program Run Mode, the process setpoint and event outputs
are controlled by the program selected.
3.18 Changing The Program Timebase
While a program is running, the normal timebase is hours/minutes. To change to a timebase of minutes/seconds (i.e. select the x60 facility) press the UP key for more than five seconds, whereupon the x60 indicator will go on. To cancel operation on the x60 timebase, press the DOWN key for more than five seconds, whereupon the x60 indicator will go off.
32
3.19 Holding A Program Manually
The operator may hold or freeze a program by momentarily pressing the RUN/HOLD key. The HLD indicator will then go on (the RUN indicator staying on) and the program will stop execution. The program may subsequently be restarted by momentarily pressing the RUN/HOLD key again.
HLD INDICATOR FLASHING: Before the operator holds the program manually, the HLD indicator may start flashing. This indicates that the program is currently subject to a Deviation-Hold. If the RUN/HOLD key is pressed (for a manual Hold), the HLD indicator will go on continuously. When the operator removes the manual Hold (by pressing the RUN/HOLD key again), the HLD indicator will either flash (indicating that the Deviation-Hold conditions still prevail) or go off (indicating that the Deviation-Hold conditions no longer prevail).
RUN INDICATOR FLASHING: This indicates that the program is in a Delay state (i.e. is timed to start after a user-defined delay has elapsed). When the delay period has elapsed, the program will run and the RUN indicator will come on continuously.
3.20 Jumping To The Next Segment
At any time during a program's execution, the operator may jump forward to the next segment by simultaneously pressing the PROF and UP keys.
Note that, since programs may be joined or set to cycle, jumping past the last segment in a program may result in changes in the Program Number and Cycle Count.
33
3.21 Viewing Program Progress/Status
In Program Run Mode, a number of displays are made available to the operator (in the Message Display area) which indicate program progress/ status. While the current program is running, held or delayed, press the SCROLL key to cycle through a sequence of program status displays with the following legends in the Message Display:
In the case of Segment Time Remaining or Deviation-Hold Time display, the time is in hours/minutes (if the x60 indicator is OFF) or minutes/seconds (if the x60 indicator is ON). The Delay Time display is always in hours/minutes.
Note: If the SCROLL key is held for two seconds or longer the instrument will auto­scroll through the above display cycle (with the exception of the Self-Tune and Pre­Tune displays). The auto-scroll can be stopped by pressing any key other than the SCROLL key.
34
3.22 Aborting A Program
The operator may abort (i.e. terminate) the current program by holding down the RUN/HOLD key for more than five seconds. When the program is aborted, a return is made to the Base Mode and the Message area will read Aborted.
This message will be removed by the next key press.
3.23 "End Of Program" Indication
When the program has completed its End Segment (i.e. the last segment to be performed), the message display will read At End, and a return is made to the Base Mode. Press any key to clear the Message Display.

SECTION 4: ACCESSING MODES OF THE CONTROLLER
The control has various modes in which the control parameters can be viewed or changed. A list of available modes is shown along with a brief description of their purpose.
To access a mode, press the MODE key until the desired mode appears in the message display. Press the SCROLL key to enter the mode. Refer to other sections of this manual for detailed information on each mode. Any mode which has been disabled in the Enable Mode will not be displayed, and may not be accessed.

SECTION 5: USING THE PRETUNE AND AUTOTUNE FEATURES
5.1 Using The Pre-Tune Facility
The Pre-Tune facility is used to set the instrument's PID control parameters to values which are approximately correct in order to provide a base from which the Auto-Tune facility may subsequently optimize tuning. Pre-Tune may be activated as follows:
1. With the instrument in Base mode (with the RUN and HLD indicators off), press the
MODE key until the Message Display reads PreTune and the lower Main Display
shows reads OFF.
2. Press the UP key to change the lower Main Display to ON, indicating that the Pre-
Tune facility is now activated. The AT indicator will flash.
NOTES:
1. If the process variable is within 5% of the input span from the setpoint, the
Pre-Tune facility cannot be activated and any attempt to do so will have no
effect.
2. Since the Pre-Tune facility is a single-shot operation., it will automatically de-
activate itself once the operation is complete.
To de-activate the Pre-Tune facility manually (with the instrument in Base Mode), access the Pre-Tune mode using the instructions above; then press the DOWN key to change the lower Main display from ON to OFF.
5.2 Using The Auto-Tune Facility
The Self-Tune facility is used to optimize tuning while the Controller part of the instrument is operating. Auto-Tune may be activated as follows:
1. With the instrument in Base Mode (with RUN and HLD indicators OFF), press the
MODE key until the Message Display reads AutoTune and the lower Main Display
reads OFF.
2. Press the UP key to change the lower Main Display to ON, indicating that the Auto-
Tune facility is now activated. The AT indicator is on continuously. To de-activate the Auto-Tune facility, access the Auto-Tune mode using the instructions
above, then press the DOWN key to change the lower Main Display from ON to OFF.
39
40
SECTION 6: PROFILE SET MODE
The instrument may be put into Profile Set Mode from either Base Mode or Program Run Mode (i.e. with a program currently running). This mode allows editing or viewing of a program profile.
6.1 Entry Into Profile Set Mode
To enter the Profile Set Mode from Base Mode:
1. Press the MODE key until PROF PAR appears in the message display
2. Press the SCROLL key to enter the Profile Set Mode. To return to Base Mode:
1. Press the MODE key until Basemode appears in the message display.
2. Press the SCROLL key to return to Base Mode. In Profile Set mode, the operator will be presented with the first of a sequence of
parameter displays. The operator may then step through the sequence, using the SCROLL key. The parameter setting (in the lower Main Display) may be changed using the UP/DOWN keys. The displayed Program Number may be changed using the PROF key and the displayed Segment Number may be changed using the RUN/HOLD key.
The instrument may be fitted with an optional internal 24 hour clock. This clock provides the time period information for the power fail recovery feature (see section 6) and permits a program profile to be started at a specific time of day.
Profile Set Mode parameters are divided into three categories: a) GLOBAL - Those common to all programs To view the parameters in the Global category, press the PROF key until the Program
Number shown is "A". Press the RUN/HOLD key until the Segment Number shown is blank.
41
b) PROGRAM - Those which apply to a specific program as a whole To view parameters in the Program category, press the PROF key until the desired
Program Number is displayed. Press the RUN/HOLD key until the Segment Number shown is blank.
c) SEGMENT - Those relevant to a specific segment in a specific program To view parameters in the Segment category, press the PROF key until the desired
Program Number is displayed. Press the RUN/HOLD key until the desired Segment Number is displayed.

Otherwise, the next depression of the SCROLL key will display the next segment final SP, or Event for the current segment if the Event Output hardware is fitted.
† This parameter appears in the sequence only if the Event Output hardware is fitted, in which case this parameter will be followed by the Final Setpoint Value parameter for the next segment. If this hardware is not fitted, this parameter will be omitted from the sequence and the segment number will be advanced, causing the Final Setpoint Value parameter for the next segment to appear immediately.
47
CANCELLING JOIN, REPEAT OR END PROGRAM SEGMENTS This can be achieved: (a) at the Final Setpoint Value parameter, by simultaneously pressing the UP/DOWN
keys to produce a Dwell segment, or
(b) at the Segment Time/Ramp Rate parameter, by incrementing the value to 0 or a
positive value.
6.5 Using Join, Repeat And End Segments And Cycling Programs
By default, the instrument has eight programs, each 16 segments long (all 16 segments are active and, at the end of Segment 16 is an implicit End Segment). These programs can be made shorter (using End segments) or longer (by creating program sequences with Join, Repeat and End segments). The only limit to the size of a program sequence is a maximum length of 121 active segments plus seven Join segments plus one End segment (i.e. all eight programs joined to make one program sequence).
Segments follow a free format in that ramp or dwell can be followed by dwell or ramp, completely as desired.
Consider two example programs:
To join the two programs to form a program sequence, change the End segment of Program 1 to a Join segment (Segment Time or Ramp Rate set to J02 - Join Program
2):
48
There are no restrictions on joining programs; several programs can be joined to one program (i.e. to prove user-selectable warm-up programs, depending upon which program is run first).
The Cycle feature can be used to make more complex program sequences. Consider the two simple example programs previously described:
Also consider the case where Program 1 is set to perform two cycles and Program 1 is joined to Program 2. When Program 1 is run, the result would be:
If Program 2 were now set to perform ten cycles, the result would be:
49
Now, with Program 2 set to perform 10 cycles, change its last segment to a Repeat segment (Segment Time or Ramp Rate set to REP); the result would be:
At the end of the tenth cycle of Program 2, the program sequence would end.
6.6 Basic Rules To Remember
In any program sequence:
A program ending in a Join segment will perform the required number of cycles of itself before joining the new program.
A program ending in a Repeat segment (hence, by definition, the last program in the sequence) will perform the required number of cycles of itself before ending the sequence.
A program ending in an End segment (hence, by definition, the last program in the sequence) will perform its cycle on the entire program sequence before ending that sequence.
6.7 Exiting Profile Set Mode
The operator may exit from Profile Set Mode by pressing the MODE key. To return to Base Mode, press the MODE key until the Base Mode prompt appears in the Message Display, then press the SCROLL key.

Notes on Tune Parameters Mode
1. The Input Correction value should be chosen with care. Any adjustment to this parameter is, in effect, a calibration adjustment. Injudicious application of values to this parameter could lead to the displayed process variable value bearing no meaningful relationship to the actual process variable value. There is no front panel indication when this parameter is in effect (i.e. has been set to a non-zero value).
2. These parameters are applicable only if the secondary control (COOL) output is fitted.
3. These parameters are not applicable if Proportional Band 1 is set to 0 (i.e. ON/OFF control).
4. This parameter is not applicable if Proportional Band 1 is set to 0 or if Output 2 (COOL) is not fitted.
5. The message Display will show Diff 1 for ON/OFF control on Output 1 only, Diff 2 for ON/OFF control on Output 2 only or Diff for ON/OFF control on both Output 1 and Output 2.
6. These parameters are not applicable if the Recorder Output option is not fitted.
7. Output 1 cycle Time is not applicable if Proportional Band 1 is set to 0 or if Output 1 is a DC linear output. Output 2 cycle Time is not applicable if Proportional Band 1 is set to 0, if Output 2 is not fitted or if Output 2 is a DC linear output.
8. These parameters only apply if the proportional band has been set to 0.

On power-up, an "alarm" condition may occur, based on the alarm value, the process value and, if appropriate to the alarm type, the setpoint value. This would normally activate an alarm; however, if the pertinent alarm is inhibited, the alarm indication is suppressed and the alarm will remain inactive. This will prevail until the "alarm" condition returns to the "inactive" state, whereafter the alarm will operate normally.
8.2 Loop Alarm And Loop Alarm Time
The Loop Alarm is a special alarm which detects faults in the control feedback loop by continuously monitoring process variable response to the control output(s).
The Loop Alarm facility, when enabled, repeatedly checks the control output(s) for saturation i.e. either or both outputs being at the maximum or minimum limit. If an output is found to be in saturation, the Loop Alarm facility starts a timer; thereafter, if the saturated output has not caused the process variable to be corrected by a pre­determined amount V after a time T has elapsed, the Loop Alarm goes active. Subsequently, the Loop Alarm facility repeatedly checks the process variable and the control output(s). When the process variable starts to change value in the correct sense or when the saturated output comes out of saturation, the Loop Alarm is deactivated.
For PID control, the Loop Alarm Time T is always set to twice the value of the Reset (Integral Time Constant) parameter. For On/Off control, the user defined value of the Loop Alarm Time parameter is used.
The value of V is dependent upon the input type:
°C ranges: 2° C or 2.0° C °F ranges: 3° F or 3.0° F Linear ranges: 10 least significant display units
For single output controllers, the saturation limits are 0% and Output Power Limit. For dual output controllers, the saturation limits are -100% and Output Power Limit.
61
Notes:
1. Correct operation of the Loop Alarm depends upon reasonably accurate PID tuning.
2. The Loop Alarm is automatically disabled during Manual Control Mode and during execution of the Pre-Tune facility. Upon exit from Manual Control Mode or after completion of the Pre-Tune routine, the Loop Alarm is automatically re-enabled.
When full ON/OFF control is selected (i.e. Proportional Band 1 is set to 0) and Loop Alarm is enabled, the Loop Alarm Time parameter determines the duration of the saturation condition after which the Loop alarm will be activated. It may be adjusted within the range 1 second to 99 minutes 59 seconds. This parameter is omitted from the display sequence if ON/OFF control is not selected or Loop Alarm is disabled. The default setting is 99:59.

SECTION 9: ENABLE MODE
The Enable mode controls which modes are readily available to the operator. If a mode is disabled or off, it will not be displayed when the MODE key is pressed in Base Mode. If a mode is set to Read Only, that mode is not available to be changed by the operator, such as the Setpoint Change and AutoTune settings.
To enter the Enable Mode from Base Mode:
1. Press the MODE key until Enable appears in the message display.
2. Press and hold the SCROLL key for five seconds to access the Enable Mode.
3. With PassCode displayed in the message display, use the UP and DOWN keys to set the pass code in the numerical display.
4. With the proper pass code displayed, press the SCROLL key.
If a proper pass code has been entered, the control will enter the Enable Mode, with EnAb shown in the lower display. If an improper pass code has been entered, the control will revert back to the Enable prompt.
Once the Enable Mode has been accessed, if no key is pressed for more than one minute, the instrument will automatically revert to Base Mode.
Press the SCROLL key to step through the parameters. Press the UP and DOWN keys to change the parameter setting.

SECTION 10: CONFIGURATION MODE
10.1 Entering The Configuration Mode
To enter the Configuration Mode from Base Mode:
1. Press the MODE key until ConfPar appears in the message display.
2. Press the SCROLL key to enter the Configuration Mode.
To return to Base Mode:
1. Press and hold the MODE key for 5 seconds. The instrument will cycle through its power-up sequence and return to BASE mode.
The user may step through the Configuration Mode parameters using the SCROLL key. For each parameter, the Message Display will show a legend identifying that parameter and the lower main display will show the current setting of that parameter. The setting may be adjusted using the UP/DOWN keys. As soon as the setting is changed, the lower main display will flash, indicating that the new setting has yet to be confirmed. When the setting is as required, it may be confirmed by pressing the PROF key, whereupon the upper display will stop flashing.
NOTE: Changes to certain Configuration Mode parameters (i.e. input range, output use and type) will cause other mode parameters to be automatically set to their default values. Items affected include Tune Mode, and Pretune and Auto Tune Facilities. Until the Tune Mode settings have been verified by changing at least one parameter, the upper main display will show decimal points to indicate that the values are in their default condition.
Changes to Configuration Mode parameters will not be accepted until they have been verified with the PROF key.
65
10.2 Hardware Definition Code
This parameter is a special facility in Configuration Mode, which is used to specify the hardware fitted (input type, output types, etc.); this must be compatible with the hardware actually fitted. It can be accessed, with the instrument in Configuration Mode, by simultaneously pressing the DOWN and SCROLL keys. The Message Display will then read HwDefine, and the lower main display will be of the form:
The displayed code may be incremented/decremented using the UP/ DOWN keys as required. The maximum setting available for this code is 4777. For example, the code for a thermocouple input, 4-20mA DC primary output (Output 1) and relay Output 3 would be 2701. When the code is first altered, the code display will flash, until the desired value is displayed and confirmed by pressing the PROF key.
NOTE: It is essential that this code is changed promptly whenever there is a change to the instrument's hardware configuration (change of input/output type, alarm/recorder output added/removed etc.). The instrument software depends upon this code to operate correctly. To save any changes made in Hardware Define Mode, the PROF key must be pressed when the desired setting is flashing.
Hardware Definitions also may be viewed as Read Only displays in Base Mode by pressing the SCROLL and DOWN keys simultaneously.

Notes on Configuration Mode Parameters
1. If the secondary output is chosen as Output 2 (COOL) control output, its action is always the compliment of the action of Output 1.
2. The default setting for Output 2 Usage is Alarm 2 hardware output, direct-acting (if relay/SSR output) or Output 2 - COOL (if DC output).
3. The default setting for Output 3 Usage is Alarm 1 hardware output, direct-acting (if relay/SSR output) or Process Variable Recorder Output (if DC output)
4. This parameter does not appear in the sequence if the input type selected is not thermocouple. If the CJC is disabled, the initial display in Operator Mode will show horizontal bars flashing in the lower display.
5. The primary input default setting is dependent upon the hardware fitted, as indicated in the Hardware Definition Code.
6. These parameters do not appear if the Hardware Definition Comms parameters is set to none.
7. This parameter does not appear if the Programmer communications option is set to operate in Master mode.
8. Internal software prevents (a) the Setpoint High Limit being given a value less than any setpoint value contained in currently-resident programs, and (b) the Setpoint Low Limit being given a value greater than any setpoint value contained in currently­resident programs.
9. These parameters are applicable only if a linear input is fitted.
10. These parameters do not appear if features are not fitted.

To enter the Calibration Mode from Base Mode:
1. Press the MODE key until Calib appears in the message display.
2. Press the SCROLL key to enter the Calibration Mode.
To return to Base Mode, cycle power to the control.
12.1 Calibration Procedure
NOTE: Calibration should be attempted only on Controllers on which calibration errors have been encountered (see CALIBRATION CHECK).
CALIBRATING THE UNIVERSAL INPUT Equipment Required
1. Input source with an accuracy better than +/- 0.05 of reading:
a) Thermocouple inputs: Thermocouple simulator, “K” type with compensated leads b) DC linear inputs: 0 - 50 mV, 0 - 10 V or 0 - 20 mA c) RTD inputs: decade resistance box with connections for three-wire input (or
equivalent)
2. Case assembly, wired for appropriate input supply (90 - 264 VAC 50/60 Hz, 20 - 50 VAC 50/60 Hz or 22 - 65 VDC)
Calibration Procedure
1. Ensure that the Controller is powered-off and that the mains (line) lead is disconnected. On the CPU PCB, fit the appropriate link jumpers (see Figure B-3, Appendix B). Connect the appropriate input lead (see Table 12-1).
2. Connect the mains (line) lead to the Controller. Power-up the Controller and leave switched on for five minutes (for RTD and DC Linear inputs) or 30 minutes (for thermocouple inputs).
75
3. Enter Calibration Mode. The lower main display will then show Input Type Number, in the form:
iP_I
and the message display will show:
Calib Using the UP/DOWN keys, change the input type number as required (see Table 12-1). NOTE: If required, only one input type may be calibrated. Exception: If it is required to
calibrate the thermocouple input (Input Type 5), it is necessary first to calibrate the DC 0 - 50 mV input (Input Type 1).
4. Press the PROF key to change the lower main display to show: _ _ _ _ After a few seconds, the lower main display will either (a) return to the initial Input Type
Number display if calibration was successful, or (b) display:
FAIL
In the latter case, the link jumpers and wiring should be checked.
5. To calibrate all inputs, repeat Steps 1 to 4 for each of the other input types (see
Table 12-1) until all five input types have been successfully calibrated.
The universal input calibration procedure is now complete.

EXIT FROM CALIBRATION MODE To exit from Calibration Mode, cycle power to the instrument. NOTE: An automatic exit is made from Calibration Mode if there is no key activity for
two minutes.
CALIBRATION CHECK
1. Set the Controller to the required configuration (using link jumpers and front panel
entry) as described in the appropriate Site Manual.
2. Power-up the Controller and leave it powered-up for at least five minutes (for RTD
and DC linear inputs) or at least 30 minutes (for thermocouple inputs).
3. After the appropriate delay for stabilization has elapsed, check the calibration by
connecting the appropriate input source and checking a number of cardinal points.
