In last nearly a hundred years although PID control has been used and proved to be an efficient controlling method by many industries, yet the PID is difficult to deal with some sophisticated systems such assecond and higher order systems, long time-lag systems, during set point change and/or load disturbance circumstance etc. The PID principle is based on a mathematic modeling which is obtained by tuning the process. Unfortunately , many systems are too complex to describe in numerical terms precisely. In addition, these systems may be variable from time to time. In order to overcome the imperfection of PID control, the Fuzzy Technology is introduced. What is the Fuzzy Control ? It works like a good driver. Under different speeds and circumstances, he can control a car well with experiences he had before and does not require the knowledge of kinetic theory of motion. The Fuzzy Logic is a linguistic control which is different from the numerical PID control. It controls the system by experiences and does not need to simulate the system precisely as been controlled by PID.

2 3 Wiring Precautions2 3 Wiring Precautions

Before wiring, verify the label for correct model number and options. Switch off the power while checking.

Care must be taken to ensure that maximum voltage rating specified on the label are not exceeded.

It is recommended that power of these units to be protected by fuses or circuit breakers rated at the minimum value possible.

All units should be installed inside a suitably grounded metal enclosure to prevent live parts being accessible from human hands and metal tools.

All wiring must conform to appropriate standards of good practice and local codes and regulations. Wiring must be suitable for voltage, current, and temperature rating of the system.

The " stripped " leads as specified in Figure 2.2 below are used for power and sensor connections.

Beware not to over-tighten the terminal screws.

Unused control terminals should not be used as jumper points as they may be internally connected, causing damage to the unit.

Verify that the ratings of the output devices and the inputs as specified in Chapter 8 are not exceeded.

Electric power in industrial environments contains a certain amount of noise in the form of transient voltage and spikes. This electrical noise can enter and adversely affect the operation of microprocessor-based controls. For this reason we strongly recommend the use of shielded thermocouple extension wire which connects the sensor to the controller. This wire is a twisted-pair construction with foil wrap and drain wire. The drain wire is to be attached to ground at one end only.

2 5 Sensor Installation Guidelines2 5 Sensor Installation Guidelines

Proper sensor installation can eliminate many problems in a control system. The probe should be placed so that it can detect any temperature change with minimal thermal lag. In a process that requires fairly constant heat output, the probe should be placed closed to the heater. In a process where the heat demand is variable, the probe should be closed to the work area. Some experiments with probe location are often required to find this optimum position.

In a liquid process, addition of a stirrer will help to eliminate thermal lag. Since the thermocouple is basically a point measuring device, placing more than one thermocouple in parallel can provide an average temperature readout and produce better results in most air heated processes.

Proper sensor type is also a very important factor to obtain precise measurements. The sensor must have the correct temperature range to meet the process requirements. In special processes the sensor might need to have different requirements such as leak-proof, anti-vibration, antiseptic, etc.

Standard sensor limits of error are 4degrees F ( 2degrees C ) or 0.75% of sensed temperature (half that for special ) plus drift caused by improper protection or an over-temperature occurrence. This error is far greater than controller error and cannot be corrected on the sensor except by proper selection and replacement.

The ON-OFF control may introduce excessive process oscillation even if hysteresis is minimized to the smallest. If ON-OFF control is set ( ie. PB1=0), TI1, TD1, CYC1, OFST, CPB and PL1 will be hidden and have no function to the system. The manual mode, auto-tuning, self-tuning and bumpless transfer will be disabled too.

Select REVR for OUT1, set TI1 to 0, SP1 is used to adjust set point value, TIME is used to adjust the dwell timer ( enabled by selecting TIMR for A1FN or A2FN ). OFST been enabled in case of TI1 = 0 is used to adjust the control offset ( manual reset ). Adjust CYC1 according to the output 1 type ( O1TY ).Generally, CYC1= 0.5 ~ 2 sec for SSRD and SSR, CYC1=10 ~ 20 sec for relay output .CYC1 is ignored if linear output is selected for O1TY. if PB1 is not equal to 0.

OFST is measured by % with range 0 - 100.0 %. In the steady state ( ie. process has been stabilized ) if the process value is lower than the set point a definite value, say 5 C, while 20 C is used for PB1, that is lower 25 %, then increase OFST 25 %, and vice versa. After adjusting OFST value, the process value will be varied and eventually, coincide with set point. Using the P control ( TI1 set to 0 ), the auto-tuning and self-tuning are disabled. Refer to section 3-20 " manual tuning " for the adjustment of PB1 and TD1. Manual reset ( adjust OFST ) is not practical because the load may change from time to time and often need to adjust OFST repeatedly. The PID control can avoid this situation.

Selecting REVR for OUT1, SP1 is used to adjust set point value. TIME is used to adjust the dwell timer ( enabled by selecting TIMR for A1FN or A2FN ). PB1 and TI1 should not be zero. Adjust CYC1 according to the output 1 type ( O1TY ). Generally, CYC1 = 0.5 ~ 2 sec for SSRD and SSR, CYC1 = 10 ~ 20 sec for relay output. CYC1 is ignored if linear output is selected for O1TY. In most cases the self-tuning can be used to substitute the auto-tuning. See

If self-tuning is not used ( select NONE for SELF ), then use auto-tuning for the new process, or set PB1, TI1 and TD1 with historical values. See for auto-tuning operation. If the control result is still unsatisfactory, then use manual tuning to improve the control . See

REVR for OUT1, SP1 is used to adjust set

point

value. TIME is used to adjust the dwell timer ( enabled by selecting

TIMR

for A1FN or A2FN ). PB1 and TI1 should not be zero. Adjust CYC1

according

to the output 1 type ( O1TY ). Generally, CYC1 = 0.5 ~ 2 sec for

SSRD

and SSR, CYC1 = 10 ~ 20 sec for relay output. CYC1 is ignored if

linear

output is selected for O1TY.

In

most cases the self-tuning can be used to substitute the auto-tuning. See

If

self-tuning is not used ( select NONE for SELF ), then use

auto-tuning

for the new process, or set PB1, TI1 and TD1 with historical values.

See for

auto-tuning operation. If the control result is still

unsatisfactory,

then use manual tuning to improve the control . See

NOTE :

Other Setup Required :

The ON-OFF control may result excessive overshoot and undershoot problems in the process. TheP(orPD) control will result in a deviation process value from the set point. It is recommended to use PID control for the Heat-Cool control to produce a stable and zero offset process value.

O1TY, CYC1, O2TY, CYC2, A2SP, A2DV O1TY & O2TY are set in accordance with the types of OUT1 & OUT2 installed. CYC1 & CYC2 are selected according to the output 1 type ( O1TY ) & output 2 type ( O2TY ). Generally, selects 0.5 ~ 2 sec. for CYC1, if SSRD or SSR is used for O1TY; 10 ~ 20 sec. if relay is used for O1TY, and CYC1 is ignored if linear output is used. Similar condition is applied for CYC2 selection. If OUT2 is configured for ON-OFF control ( by selecting = AL2 ), the OUT2 acts as alarm output, and the process alarm as well as deviation alarm ( see section 3-8 & 3-9 ) can be used. Adjust A2SP to change set point if process alarm is used, and adjust SP1 ( with preset A2DV ) to change set point if deviation alarm is used.

Adjustment of CPB is related to the cooling media used. For air is used as cooling media, adjust CPB at 100(%). For oil is used as cooling media, adjust CPB at 125(%). For water is used as cooling media, adjust CPB at 250(%).

DB Programming: Adjustment of DB is dependent on the system requirements. If more positive value of DB ( greater dead band ) is used, an unwanted cooling action can be avoided but an excessive overshoot over the set point will occur. If more negative value of DB ( greater overlap ) is used, an excessive overshoot over the set point can be minimized but an unwanted cooling action will occur. It is adjustable in the range -36.0% to 36.0 % of PB1 ( or PB2 if PB2 is selected ). A negative DB value shows an overlap area over which both outputs are active. A positive DB value shows a dead band area over which neither output is active.

3 8 Process Alarms3 8 Process Alarms

There are at most two independent alarms available by adjusting OUT2. If =AL2 is selected for OUT2, then OUT2 will perform alarm 2 function. Now A2FN can't be selected with NONE, otherwise will be displayed. A process alarm sets an absolute trigger level ( or temperature ). When the process ( could be PV1, PV 2 or PV1-PV2 ) exceeds that absolute trigger level an alarm occurs. A process alarm is independent from set point. Adjust A1FN ( Alarm 1 function ) in setup menu. One of 8 functions can be selected for process alarm. These are : PV1.H, PV1.L, PV2.H, PV2.L, P1.2.H, P1.2.L, D1.2.H, D1.2.L. When the PV1.H or PV1.L is selected the alarm examines the PV1 value. When the PV2.H or PV2.L is selected the alarm examines the PV2 value. When the P1.2.H or P1.2.L is selected the alarm occurs if the PV1 or PV2 value exceed the trigger level. When the D1.2.H or D1.2.L is selected the alarm occurs if the PV1-PV2 ( difference ) value exceeds the trigger level. The trigger level is determined by A1SP ( Alarm 1 set point ) and A1HY ( Alarm 1 hysteresis value ) in User Menu for alarm 1. The hysteresis value is introduced to avoid interference action of alarm in a noisy environment. Normally A1HY can be set with a minimum ( 0.1 ) value. A1DV and/or A2DV are hidden if alarm 1 and/or alarm 2 are set with process alarm.

When a normal alarm is selected, the alarm output is de-energized in the non-alarm condition and energized in an alarm condition.

If a latching alarm is selected, once the alarm output is energized, it will remain unchanged even if the alarm condition is cleared. The latching alarms are disabled when the power is shut off or if event input is applied with proper selection of EIFN.

A holding alarm prevents an alarm from power up. The alarm is enabled only when the process reaches the set point value ( may be SP1 or SP2,

See event input ). Afterwards, the alarm performs same

function as normal alarm.

Here is an example. A process is equipped with a heater, a sensor and a subject to be warmed up. Due to the design and position of the components in the system, the sensor could not be placed any closer to the part. Thermal gradient ( different temperature ) is common and necessary to an extent in any thermal system for heat to be transferred from one point to another. If the difference between the sensor and the subject is 35 C, and the desired temperature at the subject to be heated is 200 C, the controlling value or the temperature at the sensor should be 235 C. You should input -35 C as to subtract 35 C from the actual process display. This in turn will cause the controller to energize the load and bring the process display up to the set point value.

Since the hardware and software need time to be initialized, the control is abnormal

as the power is recovered and results in a large disturbance to

the

process. During the sensor breaks, the process loses power.

After bumpless transfer configured, the correct control variable is applied immediately as the power is recovered, the disturbance is small. During the sensor breaks, the controller continues to control by using its previous value. If the load doesn't change, the process will remain stable. Thereafter, once the load changes, the process may run away.

For fail safe reason, an additional alarm should be used to announce the operator when the system fails. For , a Sensor Break Alarm, if configured, will switch to failure state and announces the operator to use manual control or take a proper security action when the system enters failure mode.

Therefore, you should not rely on a

If the process value exceeds a certain limit, 500 C for example, it is desirable to use another PID values to optimize the control performance. You can use a process high alarm to detect the limit of the process value. Choose PV1H for A1FN, A1MD selects NORM, adjust A1SP to be equal to 500 C, and choose PID2 for EIFN. If the temperature is higher than 500 C, then alarm 1 is activated. The alarm 1 output is connected to event input, the PID values will change from PB1, TI1 and TD1 to PB2, TI2 and TD2.

The optimal PID values for a process may vary with its process value and set point. Hence if a process is used for a wide range of set point, dual PID values are necessary to optimize the control performance. If the first PID set is selected ( event input is not applied ) during auto-tuning procedure, the PID values will be stored in PB1, TI1 and TD1. Similarly, if the second PID set is selected ( event input is applied while PID2 or SP.P2 is selected for EIFN ) during auto-tuning, the PID values will be stored in PB2, TI2 and TD2 as soon as auto-tuning is completed.

Two types of interface are available for Data Communication. These are

and interface. Since RS-485 uses a differential architecture to drive and sense signal instead of a single ended architecture which is used for RS-232, RS-485 is less sensitive to the noise and suitable for a longer distance communication. RS-485 can communicate without error over 1 km distance while RS-232 is not recommended for a distance over 20 meters.

Using a PC for data communication is the most economic way. The signal is transmitted and received through the PC communication Port ( generally RS232 ). Since a standard PC can't support RS-485 port, a network adaptor ( such as ) has to be used to convert RS-485 to RS-232 for a PC if RS-485 is required for the data communication. But there is no need to be sad. Many RS-485 units ( up to 247 units ) can be connected to one RS232 port; therefore a PC with 4 comm ports can communicate with 988 units. It is quite economic.

The VPFW switches the load without DC current, hence minimize the harmonic current

and stress on the load. The load life is prolonged.

As the duty cycle ( ie. output power level ) of the control input is small, the off period will be extended to keep the output resolution so that the conversion error is minimized. As low as 0.1% of timing error can be achieved. Hence, VPFW SSR is particularly suitable for a smoother control.
