**High accuracy 18-bit input A D **High accuracy 15-bit output D A **Fast input sample rate (5 times / second) **Two function complexity levels **User menu conﬁgurable **Adaptive heat-cool dead band **Pump control *Fuzzy + PID microprocessor-based control *Automatic programming *Differential control *Auto-tune function *Self-tune function *Sleep mode function *“Soft-start” ramp and dwell timer *Programmable inputs (thermocouple, RTD, mA, VDC)

ETR-3400 Fuzzy Logic plus PID microprocessor-based controller, incorporates a bright, easy to read 4-digit LED display, indicating the process or set value. FUZZY LOGIC technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance. The units are housed in a 1/32 DIN case, measuring 24 mm x 48 mm with 98 mm behind panel depth. The units feature three touch keys to select the various control and input parameters. Using a unique function, you can put at most 5 parameters in front of the user menu by using SEL1 to SEL5 contained in the setup menu. This is particularly useful for quick access to commonly used settings.

ETR-3400 is powered by 11-26 V DC / AC or 90 - 264 V AC supply, incorporating a 3 amp. control relay output, 5V logic alarm output and a 3 amp. alarm relay output. The second alarm can be conﬁgured into second output for cooling purposes or a dwell timer. Alternative output options include SSR drive, triac, 4 - 20 mA and 0 - 10 volts. ETR- 3400 is fully programmable for PT100, thermocouple types J, K, T, E, B, R, S, N, L, 0 - 20 mA, 4 -20 mA and voltage signal input, with no need to modify the unit. The input signals are digitized by using a 18-bit A to D converter. Its fast sampling rate allows the ETR-3400 to control fast processes such as pressure and ﬂow. The selftune feature can be used to optimize the control parameters as soon as undesired control result is observed. Unlike auto-tuning, Self-tune will produce less disturbance to the process Digital communications, RS-485, RS-232 or 4 - 20 mA retransmission are available as an additional option. These options allow ETR-3400 to be integrated with supervisory Three different methods can be used to program the ETR-3400. 1) Use the keys on the front panel to program the unit manually, 2) Use a PC and setup software to program the unit via RS-485 or RS-232 COMM port. 3) Use P10A, a hand-held programmer speciﬁcally designed for the ETR series controllers.

Although PID control has been used and proved to be an efﬁcient controlling method by many industries, PID tuning is difﬁcult to deal wit, some sophisticated systems such as second and higher order systems, long time-lag systems, during set point change and/or load disturbance. 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 vary from time to time. In order to overcome the imperfections of PID control, Smarter Logic Technology is introduced. Smarter Logic is a linguistic control which controls the system by experience and does not need to simulate the system precisely as PID. Smarter Logic is the OGDEN trade mark for Fuzzy Logic . An ETR with Smarter Logic continues decision making and will prevent initial overshoot and set point differentials due to process disturbances. Control results are virtually perfect. Not only is control performance improved, software and design innovations have made available other improvements over conventional controllers.

Priority

The controller performs a closed loop control mode under its normal control mode operation. The controller will maintain its normal control mode when you are operating the user menu, setup menu or display mode, reloading default values or applying an event input signal. Under certain conditions the normal control mode will transfer to an Exception Mode. The exception modes include : Sleep Mode, Manual Mode, Failure Mode, Calibration Mode and Auto Tuning Mode. All these modes perform in an open loop control except the auto-tuning mode which performs ON-OFF plus PID close loop control. The mode transfer is governed by the priority as shown in Figure 1.6.

Chapter 2

22.2

Dangerous voltages capable of causing death are sometimes present in this instrument. Before installation or beginning any troubleshooting procedures the power to all equipment must be switched off and isolated. Units suspected of being faulty must be disconnected and removed to a safe location.

To minimize the possibility of ﬁre or shock hazards, do not expose this instrument to rain or excessive moisture. This control is not to be used in hazardous locations.

Do not use this instrument in areas under hazardous conditions such as excessive shock, vibration, dirt, moisture, corrosive gases or oil. The controller is only intended for installation in safe areas, or inside properly rated enclosures.

2-1 Unpacking

Upon receipt of the shipment remove the unit from the carton and inspect the unit for shipping damage.

If any damage due to transit is noticed, report and ﬁle a claim with the carrier. Record the model number, serial number, and date code for future reference when corresponding with our service center. The serial number (S/N) and date code (D/C) are labeled on the box and the housing of the control.

2-2 Mounting

Make panel cutout to dimension shown in Figure 2.1. Take both mounting clamps away and insert the controller into panel cutout.

Install the mounting clamps back. Gently tighten the screws in the clamp till the

controller front panels is ﬁtted snugly in the cutout.

2-3 Wiring Precautions

C

Fuse

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 is 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 contain 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.

2-4 Power Wiring

The controller can operate at 11-26 VAC / VDC or 90-264VAC. Check that the installation voltage corresponds with the power rating indicated on the product label before connecting power to the controller.

This equipment is designed for installation in an enclosure that will provide adequate protection against electric shock. The enclosure must be connected to earth ground.

Local requirements regarding electrical installation should be rigidly observed. Consideration should be given to prevent unauthorized persons access to the power terminals.

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 close to the heater. In a process where the heat demand is variable, the probe should be close 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 limit s of error are 4˚F (2˚C) or 0.75% of sensed temperature (half that for special) plus drift caused by improper protection or interference.

2-6 Thermocouple Input Wiring

Proper sensor installation can eliminate many problems. Thermocouple input connections are shown in Figure 2.5. The correct type of thermocouple extension lead-wire or compensating cable must be used for the distance between the controller and the thermocouple, ensuring that the correct polarity is observed throughout. Joints in the cable should be avoided, if possible.

If the length of thermocouple plus the extension wire is too long, it may affect the temperature measurement. A 400 ohms K type or a 500 ohms J type thermocouple should be used.

RTD connections are shown in Figure 2.6, with the compensating lead connected to terminal 9. For two-wire RTD inputs, terminals 9 and 10 should be linked. The three-wire RTD offers the capability of lead resistance compensation provided that the third wire is installed into PIN 9 as shown in Figure 2.6.

Two-wire RTD should be avoided, if possible, for the purpose of accuracy. A 0.4 ohm lead resistance of a two-wire RTD will produce a 1° C temperature variance every 50ft of lead length.
