The Fuzzy Logic plus PID micropro-
cessor-based controller series, incor-
porate two bright, easy to read 4-digit
LED displays, indicating process va-
lue and set point value. The Fuzzy Lo-
gic technology enables a process to
reach a predetermined set point in the
shortest time, with the minimum of
overshoot during power-up or exter-
nal load disturbance.
C148 is a 1/16 DIN size panel mount
controller. The unit is powered by 90-
250 VAC or 11-26 VDC / VAC supply,
incorporating a 14V / 40mA output
for SSR as standard. There are six
types of alarm plus a dwell timer can
be configured for the alarm output.
The units are fully programmable
for PT100 and thermocouple types
„J, K, T, E, B, R, S, N, L“ with no need
to modify the unit. The input signal is
digitized by using a 18-bit A to D con-
verter. Its fast sampling rate allows the
unit to control fast processes.
By using proprietary Fuzzy modi-
fied PID technology, the control loop
will minimize the overshoot and un-
dershoot in a shortest time. The fol-
lowing diagram is a comparison of
results with and without Fuzzy tech-
nology.
CHAPTER 1 OVERVIEW 1-1 General

High Accuracy
The series are manufactured with
custom designed ASIC(Application
Specific Integrated Circuit) tech-
nology which contains a 18-bit A
to D converter for high resolution
measurement (true 0.1°F resolution
for thermocouple and PT100) The
ASIC technology provides improved
operating performance, low cost, en-
hanced reliability and higher density.
Fast Sampling Rate
The sampling rate of the input A to D
converter reaches 5 times / second.
The fast sampling rate allows this
series to control fast processes.
Fuzzy 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 adap-
tive to various processes. The results
is to enable a process to reach a pre-
determined set point in the shortest
time, with the minimum of overshoot
and undershoot during power-up or
external load disturbance.

CHAPTER 1 OVERVIEW 1-1 General
Auto-tune
The auto-tune function allows the user
to simplify initial setup for a new sys-
tem. A clever algorithm is provided to
obtain an optimal set of control para-
meters for the process, and it can be
applied either as the process is war-
ming up (cold start) or as the process
has been in steady state (warm start ).
Lockout Protection
According to actual security require-
ment, one of four lockout levels can
be selected to prevent the unit from
being changed abnormally.
Bumpless Transfer
Bumpless transfer allows the control-
ler to continue to control by using its
previous value as the sensor breaks.
Hence, the process can be well con-
trolled temporarily as if the sensor is
normal.
Soft-start Ramp
The ramping function is performed
during power up as well as any time
the set point is changed. It can be
ramping up or ramping down. The
process value will reach the set point
with a predetermined constant rate.
Digital Filter
A first order low pass filter with a pro-
grammable time constant is used to
improve the stability of process value.
This is particularly useful in certain
application where the process value is
too unstable to be read.
SEL 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 se-
quence. There are at most 8 parame-
ters can be selected to allow the user
to build his own display sequence.
