NOTE:- Terminals 20 and 21 are not fitted to the 7200/7300 series controller.
NOTE:- . It is VERY important that terminal 15 (sensor common) is soundly connected to an earth point
on the ENGINE BLOCK, not within the control panel, and must be a sound electrical connection to the
sensor bodies. This connection MUST NOT be used to provide an earth connection for other terminals or
devices. The simplest way to achieve this is to run a SEPERATE earth connection from the system earth
star point, to terminal 15 directly, and not use this earth for other connections.
NOTE:- . If you use PTFE insulating tape on the sensor thread when using earth return sensors, ensure
you do not insulate the entire thread, as this will prevent the sensor body from being earthed via the engine
block.
