Note: 1) While panel mounting, additional distance required for
connection cables should be considered.
2) Panel thickness should be maximum 9mm.
3) If there is no 100mm free space at back side of the device,
it would be difficult to remove it from the panel.

ENDA ETC series are intended for installation in control panels. Make sure that the device is used only for intended purpose.
must be grounded on the instrument side. During an installation, all of the cables that are connected to the device must be free of energy.
The device must be protected against inadmissible humidity, vibrations, severe soiling and make sure that the operation temperature is not
exceeded. All input and output lines that are not connected to the supply network must be laid out as shielded and twisted cables. These
cables should not be close to the power cables or components. The installation and electrical connections must be carried on by a qualified
staff and must be according to the relevant locally applicable regulations.
The shielding
Logic output of the instrument is not electrically
insulated from the internal circuits. Therefore,
when using a grounding thermocouple, do not
connect the logic output terminals to the ground.
1) Mains supply cords shall meet the requirements
of IEC 60227 or IEC 60245.
2) In accordance with the safety regulation, the
power supply switch shall bring the identification of
the relevant instrument and it should be easily
accessible by the operator.

Press any
key to
deactivate
the self-

procedure.
While holding key, run message flashes. Then when key is
pressed,
self tune mode is entered if there is no probe failure. If process value is
Appropriate to begin self tune, rEdY. message flashes. Then press any key
to see Pid.t. message and self tune procedure begins.Process value must
be equal or lower than 60%of the setpoint to begin self tune procedure. If not,
tE.Hi. message flashes and device waits to decrease appropriate
temperature to begin self tune. Then rEdY. message flashes and press any
key to begin sellf tune procedure.
Before self tune procedure, A.tun. parameter must be selected yES from the
SECU menu.If self tune is achieved A.tun. parameter becomes no
automatically and S.tun menu is canceled. Before self tune procedure,
temperature setpoint value should be adjusted. When self tune procedure
begins with no failure, Pid.t. message flashes and remains during the
calculation of PID parameters. When PID parameters are calculated, P.SE.t.
message flashes. Then the device heats until setpoint value according to PID
parameters and calculates the energyrequirement for stable temperature and
writes P.SE.t. parameter as %and run mode enters.
If any key is pressed while Pid.t. message flashes, self tune prosedure is
deactivated before calculation of PID parameters. If any key is pressed while
P.SE.t. message flashes, then self tune prosedure is deactivated as PID
parameters are calculated and P.SE.t. parameter is done 0.
Entering from the programming mode to the run mode:
If no key is pressed within 20 seconds during programming mode, the data is stored automatically and the run mode is entered.
Alternatively, the same function occurs first pressing key and then pressing keys together.

input type. Minimum of A2.H.L. parameter is the value of A2.L.L.
parameter.
=Alarm2 value upper limit.
A1.L.L. =
If InP. or UnIt. parameters are changed, the minimum value of the
A1.L.L. parameter changes to the minimum scale value of the selected
Alarm1 value lower limit.
A2.L.L. =
If InP. or UnIt. parameters are changed, the minimum value of the
A2.L.L. parameter changes to the minimum scale value of the selected
input type. The maximum value is the value of A2.H.L. parameter.
Alarm2 value lower limit.
fL.Co. = Coefficient of digital filter.
Filter for display value.
Adjustable between 1 and 32. If this parameter is 1, digital filter runs most
quick. If the parameter is 31, the filter run most slow. The value of
parameter should be increased in interference.
U.SC.L. = Lower scale value for ma inputs.
Adjusable between -999 and the (U.SC.H. -100)
NOTE! If inP is selected one of the mA input types, this parameter is
seen.
d.adr.
1
baud
oFF
d.adr. = Device address.
Adjusable between 1 and 247. Difference addresses should be selected
for every device.
Baud= Modbus baud rate.
Selectable 1200, 2400, 4800 and 9600.
If baud=off,Modbus communication will be disable.
U.SC.H.
4000 U.SC.H. = Upper scale value for mA inputs.
Adjusable between (U.SC.L. +100) and 4000.
NOTE! If inP is selected one of the mA input types, this parameter is
seen.

When holding key, the value of parameter flashes and using
keys the requested value can be adjusted.
If key is pressed and held 0.6 seconds, the value of the selected
parameter changes rapidly. If waited enough,the value increases 100 at each
step. After 1 second following the release of the key, initial condition is
returned.The same procedure is valid for the decrement key.
