PROCESS CONTROL EQUIPMENT

The PXU is constructed of a lightweight, high impact, black plastic textured

case with a clear display window. Modern surface-mount technology, extensive

testing, plus high immunity to noise interference makes the controller extremely

reliable in industrial environments.

GENERAL DESCRIPTION

The PXU controller accepts signals from a variety of temperature sensors

including thermocouple or RTD. The controller can also be configured for

process inputs including 0 to 5/10 VDC, 0/4 to 20 mA DC, or 0 to 50 mV DC.

The PXU can provide an accurate output control signal (time proportional or DC

Analog Output) to maintain a process at a determined setpoint value. Dual

4-digit display readings allow viewing of the temperature/process and setpoint

value simultaneously. Front panel indicators inform the operator of alarm and

control output status. Comprehensive programming features allow this controller

to meet a wide variety of application requirements.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

manual or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

MAIN CONTROL

Do not use this unit to directly command motors, valves, or other actuators not

equipped with safeguards. To do so can be potentially harmful to persons or

equipment in the event of a fault to the controller. If redundant safeguards are not

in place, an independent and redundant temperature limit indicator with alarm

outputs is strongly recommended.

The PXU allows the user to select between PID, On/Off and Manual control

mode. The PXU has the ability to provide 2 control outputs. The control outputs

can be individually configured for Reverse or Direct (heating or cooling)

applications. The PID tuning constants can be established via on-demand auto-

tune. The PID constants can also be programmed, or fine-tuned, through the

front panel or a PC and then locked out from further modification.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

ALARMS

Alarm(s) can be configured independently for absolute high or low acting

with balanced or unbalanced hysteresis. They can also be configured for

deviation and band alarm. In these modes, the alarm trigger values track the

setpoint value. Adjustable alarm hysteresis can be used for delaying output

response. The alarms can be programmed for Automatic or Latching operation.

A selectable standby feature suppresses the alarm during power-up until the

temperature stabilizes outside the alarm region.

CAUTION: Risk of electric shock.

When the power is on, DO NOT touch the AC terminals, an electric shock may

occur. Make sure the power is disconnected when you check the input power

supply.

1. Prevent dust or metallic debris from falling into the controller and causing malfunctions. DO

NOT modify the controller.

2. The PXU is an open-type device. Make sure it is installed in an enclosure free of dust and

humidity in case of an electric shock.

3. Wait for one minute after the power is switched off to allow the unit to discharge. DO NOT

touch the internal wiring within this period of time.

effective. The following EMI suppression devices (or equivalent) are

recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)

Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated

and conducted noise (EMI), some type of contact protection network is

normally installed across the load, the contacts or both. The most effective

location is across the load.

a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing

EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the

transistor when the load is switched. One of the most effective ways is to

place a diode across the inductive load. Most RLC products with solid state

outputs have internal zener diode protection. However external diode

protection at the load is always a good design practice to limit EMI.

Although the use of a snubber or varistor could be used.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of

immunity to Electromagnetic Interference (EMI), proper installation and wiring

methods must be followed to ensure compatibility in each application. The type

of the electrical noise, source or coupling method into a unit may be different

for various installations. Cable length, routing, and shield termination are very

important and can mean the difference between a successful or troublesome

installation. Listed are some EMI guidelines for a successful installation in an

industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection

should be made as short as possible. The connection point for the shield

depends somewhat upon the application. Listed below are the recommended

methods of connecting the shield, in order of their effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

RLC part numbers: Snubber: SNUB0000

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter. Also, Signal or Control cables within

an enclosure should be routed as far away as possible from contactors, control

relays, transformers, and other noisy components.

Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the

instrument. When a separate input and output common is provided, they

should not be mixed. Therefore a sensor common should NOT be connected

to an output common. This would cause EMI on the sensitive input common,

which could affect the instrument’s operation.

Visit RLC’s web site at http://www.redlion.net/emi for more information on

EMI guidelines, Safety and CE issues as they relate to Red Lion Controls

products.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is

1.0 seTTing The CurrenT inpuT Jumper

When Input Type is selected as one of the two current input types (0-20 or

4-20), the current input jumper must be installed. The current input jumper is

factory set for Temperature and Voltage input types. To change the jumper to

Thermocouple, RTD

or Voltage Input

Current Input

(4-20 mA or 0-20 mA)

configure the input for a current input type, the inside of the unit must be

accessed and the jumper position changed.

To access the jumper, locate the two latches located on top and bottom of the

front of the unit. Starting with the top latch, insert a small flat-blade screwdriver

between the case latch and bezel while using your thumb to push out on the

bezel until the latch is disengaged. Repeat this process with the bottom latch.

After the latches are disengaged, using the flat-blade screwdriver, gently pry out

on the bezel in several areas until the unit releases from the case.

Look for the Current Input Jumper which will be located close to the pc board

area that connects to the input terminals. If a current input type is desired,

position the jumper across both pins. If input type is anything other than a

current input, position the jumper on only one pin.

All conductors should meet voltage and current ratings for

each terminal. Also, cabling should conform to appropriate

standards of good installation, local codes and regulations. It is

recommended that power (AC or DC) supplied to the controller

be protected by a fuse or circuit breaker. Strip the wire, leaving

approximately 1/4" (6 mm) bare wire exposed (stranded wires

should be tinned with solder). Insert the wire under the clamping

washer and tighten the screw until the wire is clamped tightly.



Integral action shifts the center point position of the proportional band to

eliminate error in the steady state. The higher the integral time, the slower the

response. The optimal integral time is best determined during PID Tuning.

By ramping the setpoint at a controlled rate, the setpoint ramp rate can reduce

sudden shock to the process and reduce overshoot on startup or after setpoint

changes. When viewing setpoint value, and the setpoint is ramping, the setpoint

will alternate between rSPx and the target setpoint value. The ramp rate is in least-

significant (display units) digits per minute. A value of 0 disables setpoint

ramping. Once the ramping setpoint reaches the target setpoint, the setpoint ramp

rate disengages until the setpoint is changed again. If the ramp value is changed

during ramping, the new ramp rate takes effect. If the setpoint is ramping prior to

starting Auto-Tune, the ramping will terminate when Auto-Tune starts. Deviation

and band alarms are relative to the target setpoint, not the ramping setpoint. A

slow process may not track the programmed setpoint rate. At power up, the

ramping setpoint is initialized to the current temperature/process value.

This determines the action for each Output. When programmed as r1d2,

Output 1 will function in the Reverse mode (heating) and Output 2 will function

in the Direct mode (Cooling). When selected as A, OP2 is configured as the

alarm 3 output and the alarm 3 settings will become accessible in the Alarm

It is the total time for one on and one off period of an OP1 time proportioning

control output. With time proportional control, the percentage of power is

converted into an output on-time relative to the cycle time value set. (If the

controller calculates that 65% power is required and a cycle time of 10.0

seconds is set, the output will be on for 6.5 seconds and off for 3.5 seconds.)

For best control, a cycle time equal to one-tenth or less, of the natural period of

oscillation of the process is recommended. When OP1 is an analog output, the

Cycle Time is the analog output update time. A Cycle Time selection of 0.0 will

serial COmmuniCaTiOns

When using a PXU with RS485 communications option, the PXU will support Modbus communications. Unit configuration,

as well as data interrogation, can be accomplished through Modbus communications. The PXU allows for 32 Read / Write

registers. A complete list of Modbus registers is available at the end of this document.

PXU CONFIGURATION USING CRIMSON

CRIMSON SOFTWARE

Crimson is a Windows^®based program that allows configuration of the PXU

controller from a PC. Crimson offers standard drop-down menu commands to

make it easy to program the PXU controller, the PXU database can then be

saved in a PC file for future use. The Crimson 2.0 software is available at www.

redlion.net. An RS-485 PC card or USB to RS485 converter and cabling is

required. Prior to downloading or extracting the database, the PXU must be set

to Modbus RTU communications type. The proper communications port, baud

rate, and unit address must be configured in the Link, Options dialog and must

matchthebaudrateandunitaddressconfiguredinthePXUserialcommunications

module (7-SC).

1. Install Crimson software, available for download at www.redlion.net.

2. Connect communications cable from PXU to PC.

3. Supply power to PXU.

4. Configure serial parameters as Modbus RTU (rtu), 38,400 baud, address

247.

5. Create a new file (File, New) or open an existing PXU database within

Crimson.

6. Configure Crimson 2 Link options (Link, Options) to the serial port which the

communication cable is attached (in step 2).

7. Select Update (Link, Update).

PXU FREQUENTLY USED MODBUS REGISTERS

Only frequently used registers are shown below. The entire Modbus Register Table can be found at the end of this document.

The following is an example of the necessary query and corresponding response for holding register 2. In this example register 2 is the decimal value 123.

Query: 01 03 00 01 00 01 D5 CA

Response: 01 03 02 00 7B F8 67

Notes:

1. The PXU registers can be read as holding (4x) or input (3x) registers.

2. The PXU should not be powered down while parameters are being changed. Doing so may result in an in-complete write to the non-volatile memory and produce

checksum errors.

ON/OFF CONTROL

ON/OFF CONTROL - HEAT/COOL OUTPUT FIGURES

In this control mode, the process will constantly oscillate around the setpoint

value. The On/Off Control Hysteresis (balanced around the setpoint) can be

used to eliminate output chatter. Output Control Action can be set to reverse for

heating (output on when below the setpoint) or direct for cooling (output on

when above the setpoint) applications.

PID CONTROL

TYPICAL PID RESPONSE CURVE

In PID Control, the controller processes the input and then calculates a

control output power value by use of Proportional Band, Integral Time, and

Derivative Time control algorithm. The system is controlled with the new

output power value to keep the process at the setpoint. The Control Action for

PID Control can be set to reverse for heating (output on when below the

setpoint) or direct for cooling (output on when above the setpoint) applications.

For heat and cool systems, the heat and cool outputs are both used. The PID

parameters can be established by using Auto-Tune, or they can be Manually

tuned to the process.

TIME

TIME PROPORTIONAL PID CONTROL

In Time Proportional applications, the output power is converted into output

On time using the Cycle Time. For example, with a four second cycle time and

75% power, the output will be on for three seconds (4 × 0.75) and off for

one second.

AUTOMATIC CONTROL MODE

In Automatic Control Mode, the percentage of output power is automatically

determined by PID or On/Off calculations based on the setpoint and process

feedback. For this reason, PID Control and On/Off Control always imply

Automatic Control Mode.

The Cycle Time should be no greater than 1/10 of the natural period of

oscillation for the process. The natural period is the time it takes for one

complete oscillation when the process is in a continuously oscillating state.

MANUAL CONTROL MODE

In USEr Control Mode, the controller operates as an open loop system, and

does not use the setpoint or process feedback. The user adjusts the percentage

of power through the OP1 or OP2 parameter to control the power for each

Output. The Low and High Output Power limits are ignored when the controller

is in Manual.

LINEAR PID CONTROL

In Linear PID Control applications, OP1 provides a linear output signal that

is proportional to the calculated OP1 value (% Output Power). The PXU allows

the user to program the %OP value at which the analog low (An1L) and high

(An1H) output signal will be produced. The Analog Output will then be

proportional to the PID calculated % output power. For example, with 0 to 10

VDC output configured as 0 (An1L) to 100 (An1H) an OP1 value of 75% provides

an analog output of 7.5 VDC. Cycle Time will determine the update time of the

linear ouput signal.

MODE TRANSFER

When transferring the controller mode between Automatic and User/Manual,

the controlling outputs remain constant, exercising true “bumpless” transfer.

When transferring from Manual to Automatic, the power initially remains

steady, but Integral Action corrects (if necessary) the closed loop power demand

at a rate proportional to the Integral Time.

pid Tuning explanaTiOns

AUTO-TUNE

Auto-Tune is a user-initiated function that allows the controller to

automatically determine the Proportional Band, Integral Time, Derivative Time,

Integration Default, and Relative Gain (Heat/Cool) values based upon the

process characteristics. The Auto-Tune operation cycles the controlling

output(s) at the setpoint. The nature of these oscillations determines the settings

for the controller’s parameters.

Prior to initiating Auto-Tune, it is important that the controller and system be

first tested. This can be accomplished in On/Off Control or Manual Control

Mode. If there is a wiring, system or controller problem, Auto-Tune may give

incorrect tuning or may never finish. Auto-Tune may be initiated at start-up,

from setpoint or at any other process point. However, ensure normal process

conditions (example: minimize unusual external load disturbances) as they will

have an effect on the PID calculations.

The controller should automatically stop Auto-Tune and store the calculated

values when the four cycles are complete. If the controller remains in Auto-Tune

unusually long, there may be a process problem. Auto-Tune may be stopped by

entering  in .

Start Auto-Tune

Below are the parameters and factory settings that affect Auto-Tune. If these

setting are acceptable then Auto-Tune can be started just by performing three

steps. If changes are needed, then they must be made before starting Auto-Tune.

PID Adjustments

MANUAL TUNING

In some applications, it may be necessary to fine tune the Auto-Tune

calculated PID parameters. To do this, a chart recorder or data logging device is

needed to provide a visual means of analyzing the process. Compare the actual

process response to the PID response figures with a step change to the process.

Make changes to the PID parameters in no more than 20% increments from the

starting value and allow the process sufficient time to stabilize before evaluating

the effects of the new parameter settings.

A chart recorder or data logging device is necessary to measure the time

between process cycles. This procedure is an alternative to the controller’s Auto-

Tune function. It will not provide acceptable results if system problems exist.

1. Set the Proportional Band () to 10.0% of the input range for temperature

inputs and 100.0% for process inputs.

2. Set both the Integral Time (I) and Derivative Time () to 0 seconds.

3. Set the Output Cycle Time in Output Module to no higher than one-tenth

of the process time constant (when applicable).

4. Place the controller in Manual () Control Mode () and adjust the %

Power to drive the process value to the Setpoint value. Allow the process to

stabilize after setting the % Power. Note:  must be set to  in

Parameter Lockouts Module 3C.

In some unusual cases, the Auto-Tune function may not yield acceptable

control results or induced oscillations may cause system problems. In these

applications, Manual Tuning is an alternative.

PROCESS RESPONSE EXTREMES

5. Place the controller in Automatic () Control Mode (). Place the value

of % power into the Output Power Offset (OPOF). If the process will not

stabilize and starts to oscillate, set the Proportional Band two times higher

and go back to Step 4. Also put Output Power Offset (OPOF) back to zero.

6. If the process is stable, decrease Proportional Band setting by two times and

change the Setpoint value a small amount to excite the process. Continue

with this step until the process oscillates in a continuous nature.

7. Set the Proportional Band to three times the setting that caused the oscillation

in Step 6.

DIGITAL POTENTIOMETER

A PXU with an analog type Control Output 1 can be used as a digital

potentiometer. To use the PXU as a digital pot, configure the PXU for Manual

control mode. Also configure OP1 parameter to be displayed and adjusted on

display line 2. OP1 output terminals provide the analog output (digital pot)

signal. The OP1 parameter displayed on line 2 is viewed in units of % output

(0.0 to 100.0) only. If desired, the PXU line 1 display can be wired and

configured to display the output signal level in engineering units. To do this,

wire the OP1 output signal (in series for current signals and parallel for voltage

signals) to the PXU’s input and scale the input display for the desired

Engineering units. For more detailed information regarding using a PXU as a

digital potentiometer, see the “Digital Pot” Tech Note at www.redlion.net.
