Pay attention to the following points regarding electrical connections via cable gland and
terminal block:
Do not forget to tighten the cable gland after the electrical connection is finalised.
Press down the spring of spring-operated terminals as far as possible, e.g. with a
screwdriver, before you insert the cable. Otherwise a safe electrical connection
cannot be ensured.
3.5 Devices with Diaphragm Seal
Remove the protective cap or protective wrapping from the diaphragm only just before in-
stallation to prevent contamination or damage.
The diaphragm must not be touched. Do not place the device on its diaphragm. Even
small scratches or deformations may negatively influence the zero point or other charac-
teristics of the device.
Pressure transmitter and diaphragm seal are a closed system that must not be separated.
You can find further information about diaphragm seals in the document TA_031 on
www.labom.com.
3.6 Mounting the Remote Display
Optionally you can mount the display and control unit away from the measuring point in an
additional housing. The back plate of the housing is universally suitable for wall mounting
or pipe mounting for pipe diameters from 30
– 64 mm. For pipe mounting, you can order
the corresponding U-bolts from LABOM.
For best EMC protection, only use the included cable.
If you ordered the remote display together with the device, the assembly has been com-
pleted in the factory. You only need to route the cable and mount the housing with the re-
mote display.
If you have received the remote display as a retrofit kit, proceed as follows:
1. Unmount the front cover and the display unit from the PASCAL Ci4 (see 4.2).
2. Replace them with the adapter piece (round part with M12 socket) and front cover,
which were screwed onto the remote display housing for shipment. Do not forget to
connect the cable on the back with the display connector on the CPU module.
3. The cable may be shortened to on-site requirements. Colour codes on the terminals
indicate which wire should be connected to which terminal (see Figure 2).
4. Mount the remote display housing using the mounting holes to a wall, a pipe or another
suitable location.
5. Plug the M12 connector of the cable into the socket of the adapter piece.
6. Now connect the cable on the display module with the corresponding connector on the
terminal board in the remote housing and insert the display module in the same man-
ner as for the device itself (see 4.2).
7. The last step is to close the remote housing with the display cover that was previously
on the device.
