1-1 General Description1-1 General Description
The ETR-3000 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-3000 is a 1/32 DIN size panel mount controller. These units are powered by an 11-26 or 90-250 VDC/VAC
supply, incorporatinga2ampcontroloutput 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 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 ETR-3000 unit 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.
There are six independent programmable alarm modes
plus a dwell timer that can be configured for the second output.

High AccuracyHigh Accuracy
The ETR-3000 is 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 CommunicationsDigital Communications
The ETR-3000 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 RateFast 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 ControlSmarter 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 PortProgramming 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 ProtectionLockout 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 TransferBumpless 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 RampSoft-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 FilterDigital 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.

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 close 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 sensormight need to have
different requirements such as leak-proof, anti-vibration, antiseptic, etc.
Standard sensor limits of error are ±4 degrees F (± 2 degreesC)or0.75% 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. If ON-OFF
control is set (ie. PB = 0), TI, TD, CYC1, OFST, CYC2, CPB, DB will be hidden and have no function to the
system. The auto-tuning mode and bumpless transfer will be disabled too.
Select REVR for OUT1, set TI to 0, OFST is used to adjust the control offset (manual
reset). if PB 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 by a definite value,
say 5 °C, while 20 °C is used for PB, that is lower 25 %, then increase OFST 25 %, and vice versa. After adjusting the
OFST value, the process value will be varied and eventually, coincide with the set point. Using the P control (TI set to 0),
the auto-tuning is disabled. Refer to section 3-12 " manual tuning " for the adjustment of PB and TD. Manual reset
(adjust OFST)is not practical because the load may change from time to time and often need to adjust OFST
repeatedly. PID control setup can avoid this situation.
