Manual Safety instructions 1: Read this manual carefully. 2: Be aware of the environment on the installation site. Wear necessary protective equipment and follow all current safety regulations. 3: Do not operate the equipment outside the specified electrical, thermal and mechanical parameters (see datasheet). Install the device only in media for which the wetted materials have sufficient durability. (See datasheet for housing material) Max. supply voltage is 30 VDC.
Manual Maintenance The black cover is pulled off to clean the pressure sensor. The sensor can then be rinsed off with water. Under no circumstances must pressure be applied to the delicate pressure sensor membrane, as this can destroy this element!! Caution: The pressure sensor membrane is extremely delicate.
Manual Electrical mounting Cable length vs. supply voltage The cable can be lengthened with any type of cable using connection box 202922. Although the measuring signal is generally not sensitive to electrical noise, we recommend the use of a screened cable. This is especially important around VFD’s and motor power cables. Ensure that no moisture can enter the pressure compensation tube inside the cable.
