mounted. A rack mount kit may also be used to install thecontroller 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” orWarning“Exhaust” ports and close contact should be avoided.
Ensure ventalation space near the bottom and rear

Cautionof the controller for heat dissipation.

3.2 Pressure Connection

Fig. 3-1 Rack enclosure installation diagram

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.
CautionSee 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: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 thecontroller;
The maximum air source pressure shall be 120%FS of the upper limit of the range of the pressure module connected
Warningwith 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

Cautionseparator.

◆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 tochoose “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 connectedwith 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

Caution8

loosen it firstly to relief the residual gas out.

◆Reference:
ADT780 has a built-in barometer which enables gauge and absolute pressures types without connection to thereference 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
Warning

avoided..
