1-1 General1-1 General
The Fuzzy Logic plus PID microprocessor-based controller series,
incorporate two bright, easy to read 4-digit LED displays,indicating
process value and set point value. The FuzzyLogic technology
enables a process to reach a predetermined set point in the
shortest time, with the minimum of overshoot duringpower-up or
external load disturbance.
The TC48 is a 1/16 DIN size panelmount controller. The TC96 is a
1/8 DIN size panel mount controller. These units are powered by
11-26 or 90-250 VDC /VAC supply, incorporating a 2 amp control
relay output as standard. The units are fullyprogrammable for
PT100 and thermocouple types J,K, T, E, B, R, S, N, Lwith no need
to modify the unit. The input signal isdigitized by using a 18-bit
A to D converter. Its fast sampling rate allows the unit tocontrol
fast processes.
By using proprietary Fuzzy modified PID technology, the control
loop will minimize the overshoot and undershoot in a shortest
time. The following diagram is a comparisonof results with and
without Fuzzy technology.

High AccuracyHigh Accuracy
The series are manufactured with custom designedASIC(Application
Specific Integrated Circuit ) technology which contains a 18-bitA to
D converter for high resolution measurement ( true 0.1 F resolution
for thermocouple and PT100 ) and a 15-bit Dto Aconverter for linear
current or voltage control output. TheASIC technology provides
improved operating performance, low cost, enhanced reliability and
higher density.
°
Fast Sampling RateFast Sampling Rate
The sampling rate of the input Ato D converter reaches 5 times/second.
The fast sampling rate allows this series to control fast processes.
Fuzzy ControlFuzzy Control
The function of Fuzzy control is to adjust PID parameters from time to
time in order to make manipulation output value more flexible and
adaptive to various processes. The results is to enable a process to
reach a predetermined set point in the shortest time, with the minimum
of overshoot and undershoot during power-up or external load
disturbance.

Auto-tuneAuto-tune
The auto-tune function allows the user to simplifyinitial setup for a
new system. Aclever algorithm is provided to obtain an optimal set
of control parameters for the process, and itcan be applied either as
the process is warming up ( cold start )or as the process has been
in steady state ( warm start ).
Lockout ProtectionLockout Protection
According to actual security requirement, one of four lockoutlevels
can be selected to prevent the unit from beingchanged by
unauthorized personnel.
Bumpless TransferBumpless Transfer
Bumpless transfer allows the controller to continue to control by
using its previous value as the sensor breaks. Hence, theprocess
can be controlled temporarily in open loop mode.
Soft-start RampSoft-start Ramp
The ramping function is performed during power up as well as any
time the set point is changed. It can ramp up 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.
SEL FunctionSEL Function
The units have the flexibility for user to select those parameters which
are most significant to him and put these parameters in the front of
display sequence. Up to 8 parameters can be selected to allow the
user to build his own display sequence.
