1-Before mount�ng the
dev�ce �n your panel,
make sure that the
cutout �s of the r�ght s�ze.
2-Check front panel

3-Insert the dev�ce
through the cutout. If the
mount�ng clamps are on
the un�t, put out them
before �nsert�ng the un�t
4-Insert the un�t �n the
panel cut-out from the

PID Temperature Control Un�ts
- 4 d�g�t process (PV) and 4 d�g�t set (SV) d�splay
- Process �nput (TC, RTD)
- Programmable ON/OFF, P, PI, PD and PID control forms
- Adaptat�on of PID Coeff�c�ents to the system w�th Self-Tune
and AUTO-Tune operat�ons
- Programmable Heat�ng or Cool�ng Funct�ons for Control
Output
- Selectable Alarm Funct�ons for Alarm Output
ESM ser�es temperature controllers are des�gned for measur�ng and
controll�ng a process value. They can be used �n many appl�cat�ons
w�th the�r TC and RTD temperature measurement �nput, mult�-
funct�on control outputs, selectable alarm funct�ons.
They are ma�nly used �n glass, plast�c, petro-chem�stry, text�le,
automot�ve and mach�ne product�on �ndustr�es. Accurate and
advanced controll�ng �s performed w�th selectable ON-OFF, P, PI,
PD, PID and Self Tune and Auto Tune PID funct�ons.
