1.3 Installation

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.

1.4 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.

1.5 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

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.

c

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

1. Screen Blinking
Sensor failure . Sensor connection is wrong or there is no sensor connection. If buzzer function
selection parameter is 3 or 4, internal buzzer starts to operate.

2- Blinking the Screen Value
If temperature higher than the alarm parameters limit, value on the screen starts to blink.

Example-1 : If alarm function selection parameter In programming section is 1(Absolute
alarm) and minimum alarm parameter is 20 ;
When temperature is less than 20°C, value on the screen starts to blink. Also if buzzer function
selection parameter is 2 or 4 , then internal buzzer is on.

Example-2 : If alarm function selection parameter in programming section is 1 (Absolute
Alarm) and maximum alarm parameter is 50
When temperature is above 50 °C, value on the screen starts to blink. Also buzzer function
selection parameter is 2 or 4, then internal buzzer is on.

Customer

All order information of ESM-3711-CN Cooling Controller are given on the table at left. User may form
appropriate device configuration from information and codes that at the table and convert it to the
ordering codes. Firstly, supply voltage then other specifications must be determined. Please fill the order
code blanks according to your needs.
Please contact us, if your needs are out of the standards.

Note-1:If input type is selected PTC or NTC (BC= 12, 18), Temperature sensor is given with the
device.For this reason, if input type is selected as PTC,sensor type (V = 0,1 or 2) or if input type is
selected as NTC, sensor type (V = 0,3 or 4) must be declared in ordering information.

1.3 Installation

Vor Montage das Gerät visuell prüfen, ob das Gerät während der Beförderung beschädigt
wurde. Die Montage und Inbetriebnahme muss durch geschultes Personal ausgeführt werden.
Dies steht unter der Verantwortung des Käufers.
Falls aufgrund eines Fehlers oder einer Störung des Geräts eine Gefahr bestehen sollte,
Spannungsversorgung abschalten und alle elektrischen Verbindungen zum Geräts entfernen.
Standardmäßig wird das Gerät ohne Netzschalter und ohne Sicherung ausgeliefert.
Bei Bedarf müssen diese vom Anwender selbst angebracht werden.
Es muss eine zum Gerät passende Versorgungsspannung verwendet werden, um
Fehlfunktionen und Schäden zu vermeiden.
Um einen elektrischen Schock und ähnliche Unfälle zu vermeiden, darf das Gerät vor
Abschluss der Verkabelung nicht mit Spannung versorgt werden.
An dem Gerät keine Veränderungen vornehmen, und das Gerät nicht reparieren.
Eingriffe am Gerät können fehlerhafte Funktion, Beschädigung des Geräts oder
angeschlossener Geräte, elektrischen Schocks und Feuer auslösen.
Das Gerät darf unter keinen Umständen in der Nähe von brennbaren und explosiven Gasen
verwendet werden.
Die Schalttafelausschnitte können scharfe Kanten aufweisen, welche bei der Montage des
Geräts Schnittverletzungen verursachen können. Bitte treffen Sie die erforderlichen
Vorsichtsmaßnahmen.
Es ist wichtig, dass das Gerät mit den mitgelieferten Befestigungsteilen montiertwird.
Das Gerät nicht mit ungeeigneten montieren. Achten Siedarauf, dass das Gerät während der
Montage nicht herunterfällt.
Es unterliegt Ihrer Verantwortung, wenn das Gerät nicht wie in dieser Anleitung beschrieben,
verwendet wird.

1.4 Garantie

2 Jahre Garantieschutz gegen Material- und Verarbeitungsfehler.
Diese Garantie wird mit dem Vorbehalt gewährleistet, dass der Kunde
den in Garantieschein und
Bedienungsanleitung erwähnten Pflichten nachkommt.

1.5 Instandhaltung

Das Gerät muss durch geschultes Personal gewartet werden. Vor dem Zugriff auf
Innenteile, alle stromführenden Leitungen trennen. Gerät nicht mit auf Kohlenwasserstoff
basierenden Lösungsmitteln (wie Benzin, Trichlorethylen etc.) reinigen. Das Reinigen mit
diesen Lösungen kann die mechanische Sicherheit des Geräts vermindern. Verwenden Sie
ein mit Ethylalkohol oder Wasser benetztes Tuch um das Plastikgehäuse außen zu reinigen.
