1 Safety precautions

1.1 Appropriate use

In addition to differential pressure data, the PU/PI and PS10 differential pressure
transducers also record positive and negative overpressures.

Always observe the operating requirements—particularly the permissible supply
voltage—indicated on the rating plate and in the "Technical data” section of this
manual.

The instrument may only be handled as indicated in this manual. Modifications to the
instrument are prohibited. The manufacturer is not liable for damages caused by
improper use or failure to follow these instructions. Violations of this type render all
warranty claims null and void.

1.2 Shipping, assembly, electrical connections and start-up

Do not close the pressure inputs when shipping, as changes in barometric pressure
could damage instruments with low measuring ranges.

Only technical personnel who are appropriately trained and authorized by the
operator of the facility may assemble the instrument and set up its electrical
connections.

The instrument may only be operated by appropriately trained individuals who have
been authorized by the operator of the facility.

Pressurized air or breath is not to be used for performance tests, as this could
damage instruments with low measurement ranges.

Measurement errors may occur if the instrument is not kept protected from sunlight.
Specific safety precautions are given in individual sections of this manual.

1.3 Troubleshooting, maintenance, repairs, disposal

The individual responsible for the electrical connections must be notified immediately
if the instrument is damaged or if errors occur that cannot be corrected as indicated in
section 5.

This individual must take the instrument out of service until the error has been
corrected and ensure that it cannot be used unintentionally.

Always unplug the supply voltage before opening the instrument!

This instrument requires no maintenance.
Only the manufacturer may perform repairs that require the housing to be opened.
