NOTE
: The same leak detection sensor is used for both ordinary and hazardous applications.
The Leak Detection Sensor comes with 2m of cable length with flying lead connections. It is recommended to combine
leak sensor cables into a single low voltage cable bundle to send to the VFD.
It is also recommended to install the leak detects as shown below to keep track of which leak detect corresponds to each
Diaphragm as the VFD will indicate which leak detect has tripped. Leak detect #1 would correspond with the lowest cylin-
der with the signal wire tied to digital input 18 of the VFD.
