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.
