Pneumatic value limit switches open or close slot sensors which operate according to the air jet cutting system.
Signalling takes place without time-delay analogously to the movement of the actual value pointer.

Mounting
Mounting has to be done according to the general technical regulations for pressure and temperature measuring gauges
(EN 837-2 or EN 13190). Excessive vibrations can be detrimental to function and service life of the instrument. In conse-
quence, the location should be exempt from vibration.
Pneumatic connection
The pneumatic connection should be performed only by qualified personnel. The operating air pressure should
be 1,4bar ±0,1bar. The output pressure is approx. 40 mbar. Air inlet and outlet fittings are indicated on the con-
necting part. The connection figures on the type plate of the measuring gauges.
Safety remarks
When installing, commissioning and operating these instruments, the national safety regulations have to be
observed. Skilled personnel only should be allowed to work with these instruments.
Adjustment of the set pointer
The adjustment of the set pointer is made in the adjusting lock of the window by means of the adjusting key
supplied. The set pointers of the limit value switches are adjustable over the whole scale range.
Maintenance
The gauges are maintenance free. Indication and switching functions should be checked about one or two times a
year. When checking the indication and the switching functions, the gauge has to be separated from the process and
a pressure / temperature standard has to be applied. Repair can exclusively be carried out at the factory.
Notice
For the mounting of the measuring gauges onto the pressure / temperature tapping point, please refer to the
