4 Unit description

The 18D-LT x2 pressure switch functions as a switch in signal, control and settling circuits. It monitors the connected relative pressure and depending on the model of 18D-LT x2 and the set switching points or functions converts it to an analogue current or voltage signal.

5 Installation

CAUTION

Risk of injury from uncontrolled operation

If the 18D-LT x2 carries electric voltage and/or pressure during installation, uncontrolled reactions can result which lead to injuries or damage to the system.

Always ensure that the relevant part of the system does not carry live voltage and is not under pressure before the 18D-LT x2 is connected pneumatically or electrically.
The tightening torque for the attachment screws is 1.6 + 0.4Nm . Install in the open only with sufficient protection against critical environmental conditions (such as atmospheres which are corrosive or contain salt).

Connecting compressed air

CAUTION

Damage to the device

The use of incorrect connection fittings or failure to comply with limit values can lead to device damage. Stay within the limit values for pressure and temperature (see specifications data sheet 5.11.006).

Do not screw in any connection fittings with conical threads! Use only connection fittings which are axially sealed on the outside flange with a maximum screw-in depth of 9mm
Construct the counter piece for the plug-in connection with a suitable Thread.

6 Startup and operation

Setting the switching points

The switching points are freely adjustable in the pressure switching range. Switching points should ideally be in the middle of the pressure switching range. Do not use the limit value (corresponds to the test pressure) during operation. To set the switching points, loosen lock screw 5. The upper and lower switching points are set by turning adjustment screw 4 (turn to the right for rising and to the left for falling pressure). The adjustment value can be checked with a manometer. To complete the procedure, tighten lock screw 5.
