1- Before mounting the device in your panel,
make sure that the cutout is of the right size.

2- Check front panel gasket position.
3- Insert the device through the cutout. If the

mounting clamps are on the unit, put out them
before inserting the unit to the panel.

4- Insert the mounting clamps to the two of
designated holes that located four sides of

Tune Operation

Starting the Tune operation
1- Enter to the program menu parameter in menu and

select ,then press button for saving parameter and turn to main
screen. Or easily press button for 3 seconds in main screen.

2- Observe that blinks in set display

Not: For starting tune operation,
Heating Tune Operation: Process value must be lower than process

set value at least 5% of full scale.
Cooling Tune Operation: Process value must be greater than
process set value at least 5% of the full scale.
If this condition is not okay, blinks on the screen for 10 seconds.

Canceling Self Tune operation:
1- If sensor breaks;
2- If self tune operation can not be completed in 8 hours;
3- While heating self tune is running, if process value becomes

greater than process set value;
4- While cooling self tune is running, if process value becomes less
than process set value;
5- While self tune operation is running, if user changes the process
set value;
Then self tune operation is canceled, device continues to run with
former PID parameters without changing PID parameters.

Installation

Before beginning installation of this product, please
read the instruction manual and warnings below
carefully.

In package,

-One piece unit

-Two pieces mounting clamp

-One piece instruction manual

A visual inspection of this product for possible damage occured
during shipment is recommended before installation. It is your
responsibility to ensure that qualified mechanical and electrical
technicians install this product.
If there is danger of serious accident resulting from a failure or defect
in this unit, power off the system and the electrical connection of the
device from the system.
The unit is normally supplied without a power switch or a fuse. Use
power switch and fuse as required.
Be sure to use the rated power supply voltage to protect the unit
against damage and to prev ent failure.
Keep the power off until all of the wiring is completed so that electric
shock and trouble with the unit can be prevented.
Never attempt to disassemble, modify or repair this unit. Tampering
with the unit may results in malfunction, electric shock or fire.
Do not use the unit in combustible or explosive gaseous
atmospheres. During the equipment is putted in hole on the metal
panel while mechanical installation some metal burrs can cause
injury on hands, you must be careful.
Montage of the product on a system must be done with it’s mounting
clamp. Do not do the montage of the device with inappropriate
mounting clamp. Be sure that device will not fall while doing the
montage.
It is your responsibility if this equipment is used in a manner not
specified in this instruction manual .

Warranty

EMKO Elektronik warrants that the equipment delivered is free from
defects in material and workmanship. This warranty is provided for a
period of two years. The warranty period starts from the delivery
date.

This warranty is in force if duty and responsibilities which are
determined in warranty document and instruction manual performs
by the customer completely.

Maintenance

Repairs should only be performed by trained and specialized
personnel. Cut power to the device before accessing internal parts.
Do not clean the case with hydrocarbon-based solvents (Petrol,
Trichlorethylene etc.). Use of these solvents can reduce the
mechanical reliability of the device. Use a cloth dampened in ethyl
alcohol or water to clean the external plastic case.

Before commissioning the device, parameters must be set in
accordance with desired use. Incomplete or incorrect configuration
can cause dangerous stiuations.
Because of lim ited mechanical life of relay output contact, SSR
output is recommended which the device use PID control algoritm.
The device with ON/OFF control algor itm, hysteresis parameter must
be set a suitable value for your system, to avoid too much relay
switching.
