Chapter 2 Installation Guide

This section is to explain the cautions the users must know in some case that possibly

injure may bring to users when it’s used or installed. For this reason, please read all details

here and make in mind before installing or using the product.

2.1 General Precautions

 Must be operated and maintained free of dust or dirty.

 The cover should be securely fastened, do not open the cover of the products when the

power is on.

 After use, securely stow away all loose cables, external antenna, and others.

2.2 Power precautions

 When you connect the power source, make sure if it may cause overload.

 Avoid operating on a wet floor in the open. Make sure the extension cable is in good

condition

 Make sure the power switch is off before you start to install the device

Item Requirement

Machine Hall

Space

When user installs machine frame array in one machine hall,

the distance between 2 rows of machine frames should be

1.2~1.5m and the distance against wall should be no less than

0.8m.

glasses for window

Wall It can be covered with wallpaper, or brightness less paint.

Fire Protection Fire alarm system and extinguisher

Power

Requiring device power, air-conditioning power and lighting

power are independent to each other. Device power requires

AC 110 ±10%, 50/60Hz or AC 220 ±10%, 50/60Hz. Please

carefully check before running.

2.5 Grounding Requirement

 All function modules’ good grounding is the basis of reliability and stability of devices. Also,

they are the most important guarantee of lightning arresting and interference rejection.

Therefore, the system must follow this rule.

 Grounding conductor must adopt copper conductor in order to reduce high frequency

impedance, and the grounding wire must be as thick and short as possible.

 Users should make sure the 2 ends of grounding wire well electric conducted and be antirust.

 It is prohibited to use any other device as part of grounding electric circuit

 The area of the conduction between grounding wire and device’s frame should be no less

than 25 mm

Chapter 3 Operation

EPS-HDM1004ECO encoder modulator’s front panel is user operating interface. Before

operating, user can decide whether directly use the default setting or customize the input and

output parameters setting. The detail operations go as follows:

Ke board Function Description:

ENTER: Activating the parameters which need modifications, or confirming the change after

modification.

MENU: To cancel presently entered value, resume previous setting and return to previous

menu.

LEFT/RIGHT: To move the “►” to choose or set the parameters.

UP/DOWN: To modify activated parameter or page up/down when parameter is inactivated.

LOCK: To Lock the screen / cancel the lock state. After pressing lock key, the system will

question the users to save present setting or not. If not, the LCD will display the current

configuration state.

At the “Factory Configuration” page, user can press “ENTER” key to restore the factory

default configuration.
