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.

Response

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.

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.
