Mechanical Installation; Mount / Dismount Display; Electrical Connection - Labom PASCAL CV4 Operating Instructions Manual

3.2

Mechanical Installation

Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
Before starting operation, check the process connection carefully for leaks under pressure.
You can use the device in any mounting position. Normally the transmitter is adjusted for a
vertical mounting position. A different mounting position in combination with a small nomi-
nal range might cause a zero point offset. In this case a zero point adjustment might be
necessary.
3.3

Mount / dismount display

In order to dismount the display, turn off the device cover and pull out the display. The
three small studs at the outer diameter of the display (all 120°) facilitate removal.
The display cable can be disconnected either at the display or at the clamp module. When
reconnecting the cable, please take polarity (red lead) into account. Otherwise the cable
will not fit into the plug.
When mounting the display, you can choose its orientation. Complete the process by firmly
reattaching the cover.

Pay attention to the following points regarding electrical connections via cable gland:
− The display can be dismounted as described in Chapter 3.3. Use a small screwdriv-
er to press the spring of the terminal block completely downwards before inserting
the cable. Otherwise, it is not possible to ensure a safe electrical connection.
− Do not forget to tighten the cable gland after the electrical connection is finalised.
