1.9 Electrical Wiring / Installation
Sensor
To connect the monitor to the sensors mounted on a
tank-truck a plug and cable set is being used.
If the monitor is set to EN13922 specifications a
10 wire cable with a Black plug MUST be used.
However, if needed and used outside the European
Union, a cable and Blue 3-J plug can be provided
(Civacon Model 7100 Series), or a cable and Green
4-J-plug can be provided (Civacon Model 7300
Series), dependent on geographic area of install or
local standards.
Although a plug and cable set can be directly connected
to the monitor it is recommended to use a junction box or
extra plug-socket breakaway to prevent or limit the
damage caused by tank-trucks driving away while the
plug still connected to the socket.
The connections of the cable to the plug according to
EN13922 are shown in Figure 7. Table 1 is showing the
alternative color-code and functional descriptions of all
10 wires.
The wire at pin 9 must be screened ensuring that the
maximum connected combined capacity of 7,7µF is
used. This is not needed if the total connected combined
capacity Co to all channels (CH 1 to 9 of J5) and J7 is
less than 4 µF.
Note : Grounded shield/screen shall be provided to CH-9 to maintain intrinsic safety (if required by the
geographic installation location’s safety approval regulations).
Only Ex certified sensors within entity parameters mentioned in Figure 7 may be connected to the 88XX when the
geographic area of installation requires compliance to EN13922.
OPW also recommends using only EN13922 sensors to ensure compatibility in these geographic installation
locations.
