1.1 Safety and Caution

The mark on the controller means that the user must pay attention to operation instructions in the manual before

operation.

The mark on the controller means that high voltage may exist at the terminal or jack. Direct contact should be

avoided.

The mark in the manual refers to high voltage or high pressure where injury could occur.

Warning

The mark in the manual Indicates product damage may occur if operation instructions are not closely followed. Any

Caution

damage resulting in incorrect use of the product is not covered under the product warranty.

II. Introduction

2.1 Overview

ADT780 Pressure Controller series can be used for a wide variety of application tests, calibrations and verifications.

ADT780 Pressure Controller has two range-dependent base units that determine the maximum pressures listed below.

Each base requires an external gas supply or Additel Electric Pump to control pressure.

● -0.1MPa ~ 7MPa; one pressure module with the range of 7MPa is embedded;

● -0.1MPa ~ 21MPa; one pressure module with the range of 21MPa is embedded;

ADT780 can be equipped externally or internally with Additel 160A series of pressure modules.

III. Installation

3.1 Installation

ADT780 pressure controller can used on a bench or rack

mounted. A rack mount kit may also be used to install the

controller on 19” (3U) cabinet. The rack mount kit includes

two fins and four installation screws. See Fig. 3-1:

When in operation gas may escape from “Vent” or

“Exhaust” ports and close contact should be avoided.

Warning

Ensure ventalation space near the bottom and rear

Caution

of the controller for heat dissipation.

3.2 Pressure Connection

Appropriate cautions and safety regulations should be observed when using gas supplies.

Warning

All pressure output is G1/8 and O-rings shall be used for sealing during connection.

Caution

See Fig. 2-3 for ADT780 pressure menu.

◆ Supply:

The Supply port is to connect a positive pressure supply to the controller. The supply should meet the following

requirements:

Fig. 3-1 Rack enclosure installation diagram

1) Air or nitrogen must be clean and dry;

2) The air supply source pressure scope shall be 110-120% of the range of the pressure module connected with the

controller;

The maximum air source pressure shall be 120%FS of the upper limit of the range of the pressure module connected

Warning

with the controller. Otherwise, injury or equipment damage may occur.

It is suggested that the positive pressure air source shall be connected to “Supply” after passing through the air-liquid

Caution

separator.

◆Vacuum:

“Vacuum” is the port which provides vacuum source for the controller. If no vacuum source is required, the port should be

open to atmosphere.

The controller is embedded with a vacuum switch solenoid valve. When the valve releases pressure from the higher

pressure to the lower pressure, gas will be exhausted from “Exhaust”. The controller can control the solenoid valve to

choose “Vacuum” only if the vacuum pressure is required.

Positive pressure applied to the vaccum port may result in injury or equipment damage.

Warning

◆Outlet:

Outlet" is the pressure output /measurement menuport. Under the measurement mode, the outlet can be connected

with external pressure (please execute the empty function before connection). Under the control mode, the controller

outputs an adjustable pressure at the set point.

The “Outlet” pressure should not exceed the pressure module range. Otherwise, injury or equipment damage may occur.

Warning

When the controller is set to measure mode and the external pressure control exceeds 2MPa, the release valve

should be tightly screwed in the “Supply” port (As Fig 7-1). If there is a need to remove this release valve, please

Caution

loosen it firstly to relief the residual gas out.
