Chapter 1 Overview
1-1 General Description
The Smarter Logic PID microprocessor-based controller incorporates a bright, easy-to-read 4-digit LED display.
The front LED display can be programmed to indicate either the process value or set point value. Smarter Logic
technology enables a process to reach a predetermined set point in the shortest possible time, with minimum
overshoot during power-up or external load disturbance.
The ETR-9100 is a 1/16 DIN size panel mount controller. The ETR-8100 is a 1/8 DIN
These units are powered by an 11-26 or 90-250 VDC/VAC
supply, incorporating a 2 amp control output relay as standard. The second output can be used as cooling control,
an alarm or dwell timer. Prior to shipment, both outputs can be independently configured as triac, 5V logic output,
linear current or linear voltage to drive an external device.
The units are fully programmable for RTD (PT100)
and thermocouple types J, K, T, E, B, R, S, N, L without the need to physically modify the unit. The input signal is
digitized by using a 18-bit A to D converter. A fast sampling rate allows the units to control fast processes.
Digital communications RS-485 or RS-232 are available as an additional option. This option allows the units to be
integrated with a supervisory control system and/or software.
A programming port is available for automatic configuration, calibration and testing without the need to access the
keys on front panel.
By using proprietary Fuzzy modified PID technology(Smarter Logic), the control loop will minimize overshoot and
undershoot in the shortest time possible. The following diagram is a comparison of results with and without Fuzzy
technology.
size panel mount controller.
The ETR-4100 is a 1/4 DIN size panel mount controller.
There are six independent programmable alarm modes
plus a dwell timer that can be configured for the second output.

High Accuracy
The ETR-9100, 8100 and 4100 series are manufactured with custom designed ASIC(Application Specific
Integrated Circuit) technology which contains an 18-bit A to D converter for high resolution measurement
(true 0.1°F resolution for thermocouple and standard Pt100 RTD’s) and a 15-bit D to A converter for linear
current or voltage control output. The ASIC technology provides improved operating performance, low
cost, enhanced reliability and higher density internal storage.

Digital Communications
The units can be equipped with an RS-485 or RS-232 interface card to provide digital communications. By
using shielded twisted pair wire, at most 247 units can be connected together via an RS-485 interface to a host
computer. An industry standard Modbus RTU is used for the communication protocol.
5
Fast Sampling Rate
The sampling rate of the input A to D converter reaches 5 times/second. This fast sampling rate allows this series to
control fast processes.
Smarter Logic Control
The function of Smarter Logic control is to automatically adjust the PID parameters from time to time. These dynamic
adjustments are made in order to tune the output value to be more flexible and adaptive to various processes. The
result is to enable a process to reach a predetermined set point in the shortest possible time with minimum overshoot
and/or undershoot during power-up or external load disturbance.
Programming Port
A programming port is used to connect the unit to a hand-held programmer or a PC for quick configuration.
Additionally, it can be connected to an Automatic Test Equipment (ATE) system for automatic testing & calibration.
Auto-tune
The auto-tune function allows the user to simplify the initial setup for a new system. A clever algorithm is provided to
obtain an optimal set of control parameters for the process. The Auto-tune feature can be applied either as the
process is warming up (cold start) or as the process is in a steady state (warm start).
Lockout Protection
In order to meet various security requirements, one of four lockout levels can be selected to prevent the unit from
being changed without authorization.
Bumpless Transfer
The Bumpless Transfer feature is a unique process protection feature that is employed upon a sensor break condition
or input problem. Bumpless transfer allows a controller to continue to proportion it’s output based on previous
process and control characteristics. Hence, the process can be temporarily controlled just as if running a closed
loop control application, making the severe problem of a Thermocouple error temporarily invisible. Bumpless transfer
is not to be used for an extended period time as in open loop control, run-away may occur.
Soft-start Ramp
The ramping function is performed during power up as well as any time the set point is changed. It ramp will control
both ramp up and/or ramp down. The process value will reach the set point with a predetermined constant rate.
Digital Filter
A first order low pass filter with a programmable time constant is used to improve the stability of process value. This
is particularly useful in certain applications where the process value is too unstable to be read.
Sel Function
The units have the flexibility for a user to select those parameters which are most significant and move these parameters
to the front of the display sequence. Up to 8 parameters may be selected to allow the user to build their own display
sequence.

2 - 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 the maximum voltage rating specified on the label is not exceeded.
It is recommended that the power of these units be protected by fuses or circuit breakers rated at the lowest
value possible.
All units should be installed inside a suitably grounded metal enclosure to prevent live parts from contact with
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.
Beware not to overtighten the terminal screws. The torque should not exceed 1 N-m (8.9 Lb-in or 10.2 KgF-cm).
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 6 are not exceeded.
Except the thermocouple wiring, all wiring should use stranded copper conductor with a maximum
gauge of 18 AWG.

2-4 Power Wiring
The controller is designed to operate at 11-26 VAC / VDC or 90-250 VAC. Check that the installation voltage
corresponds with the power rating indicated on the product label before connecting power to the controller. Near
the controller, a fuse and a switch rated at 2A/250VAC should be equipped, as shown in the following diagram.,
Figure 2.6 Power Supply Connections
This equipment is designed for installation in an enclosure which provides 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 access to the power terminals.
2-5 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 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.
90 250 VAC or
11 26 VAC / VDC
~
~
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 ±4 degrees F (± 2 degrees 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.
