Connection
Connection
The Products must be connected to an external device as per the connection diagrams
(see Appendix G).
Two LLS 20230 fuel level sensors can be connected to one BIS 20240 spark protection
unit with the KTZ splitter and two KTZ cables (Figure 41), provided that BIS 20240
voltage is at least 12 V (when connecting BIS 20240 to the on-board power supply,
FTC AVL unit, or third-party AVL unit).
When connecting the BIS 20240 spark protection unit to the battery, the BR15 galvanic
insulation unit (Figure 42) must be used.
Requirements for Cable Laying
1) For installation, use the cables produced by Omnicomm - either those included into
the delivery set or those purchased separately. 2) For connection of the LLS 20230 fuel
level sensor and the BIS 20240 spark protection unit on Zener diodes, use only KTZ-xx
cable (xx stands for the cable length determined at the time of purchase request).
Use of self-made cables or KTZ cable cutting or extension is FORBIDDEN.
3) To connect the BIS 20240 spark protection unit on Zener diodes to an external
device, use a crinkled cable produced by Omnicomm (to be purchased separately). If
needed, the cable connecting with the external device can be either extended or cut.
4) Ensure that cable laying routes are free of heated parts and units of the vehicle to
avoid cable insulation fusing.
5) To prevent cable damage, the cable should be routed in a pipe or duct.
