1.1 - GENERAL DESCRIPTION
TLK 94 is a "single loop" digital microprocessor-based controller,
with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual
action (direct and reverse) control, PID for motorized actuators with
time positioning control. The instrument is equipped with
AUTO-TUNING
SELF-TUNING function and automatic calculation of the FUZZY
OVERSHOOT CONTROL parameter for PID control. The PID
control has a particular algorithm with TWO DEGREES OF
FREEDOM that optimises the instrument's features independently
of the event of process disturbances and Set Point variations.
Furthermore,
communication using MODBUS-RTU communication protocol and
a transmission speed up to 38.400 baud. The process value is
visualized on 4 red displays, the Set value is visualized on 4 green
displays while the outputs status is indicated by 6 leds. The
function (FAST or
the instrument allows
OSCILLATING type),
for RS485 serial
