A visual inspection of this product for possible damage occurred 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 separate the electrical connection of the device from the system.

The unit is normally supplied without a power supply 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 prevent

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 putting equipment 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 fixing clamps. Do not do the montage

of the device with inappropriate fixing 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.

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.

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.

4.1 Supply Voltage Input Connection of the Device

Note-1 : External fuse is recommended.

Make sure that the power supply voltage is the same

indicated on the instrument.

Switch on the power supply only after that all the electrical

connections have been completed.

Supply voltage range must be determined in order. While

installing the unit, supply voltage range must be controlled

and appropriate supply voltage must be applied to the unit.

There is no power supply switch on the device. So a power

supply switch must be added to the supply voltage input.

Power switch must be two poled for seperating phase and

neutral, On/Off condition of power supply switch is very

important in electrical connection.

External fuse that on Vpower supply inputs must be on

phase connection.

External fuse that on Zpower supply inputs must be on (+)

connection.

time set value is shown and defrost

output led starts to fast blink (5 Hz).

Press set button for saving the defrost

time set value

Defrost time set value is saved, defrost

output led stop the fast blink (5 Hz), main

operation screen is shown.

value oscillates continuously. Temperature

value’s oscillation period or amplitude around

set value changes according to controlled

system. For reducing oscillation period of

temperature value, a threshold zone is formed

below or around set value and this zone is

named hysteresis.
