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

7

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.

8

◆Reference:

ADT780 has a built-in barometer which enables gauge and absolute pressures types without connection to the

reference port.

◆Vent:

The “Vent” port is used for the venting of gas and disposing of any liquid or contaminants (through the Empty function)

so close exposure to the port should be avoided.

When the controller is venting, gas will vent from “Vent” port and close contact should be avoided.

Warning

◆Exhaust

“Exhaust” is used for exhausting gas. When the output pressure is higher than the barometric pressure, gas will

beexhausted from “Exhaust” under the control or exhaust mode. The exhaust speed depends on the “pressure change

rate” (see Chapter 5.9 Control Setup) and differential pressure. Gas exhausted at the high speed may make some noise

even though a noise reducing muffler is installed.

Gas may be exhausted from the “Exhaust” during the operation of the controller, close contact to the port should be

avoided..

Warning

◆Barometer

“Barometer” is used for measuring the pressure of the barometric pressure sensor. The “Barometer" is equipped with

a filter. The filter should be removed before it is connected to the standard pressure source during calibration.
