1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
TLK 41 is a "single loop" digital microprocessor-based controller,
with ON/OFF, Neutral Zone ON/OFF, PID single action, PID dual ac-
tion (direct and reverse) control and with AUTO-TUNING FAST
function, 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 features independently in
the event of process disturbance and Set Point variations.
Furthermore, the instrument allows for RS485 serial communication
using MODBUS-RTU communication protocol and a transmission
speed up to 38.400 baud.
The process value is visualized on 4 red displays, while the output
status is displayed by 4 LED indicators. The instrument has also a
programmable 3 LED shift index.
The instrument can store 4 Set Points and can have up to 4 outputs:
relay type or Voltage type to drive solid state relays (SSR).
