Wiring Configurations
There are two recommended wiring configurations depending on the preferred site solution and approach to electric
level control; a direct connection to the easy-Drive actuator, shown in figure 3 or a direct connection to the easy-Drive
actuator and a remote monitor (figure 4 and 5). In these examples, the L2e is wired using a common and separate N/O
or N/C contact. When implemented as suggested, these wiring configurations provide definitive level switch points
and help reduce issues associated with single pole single throw contact switches, such as "bouncing" due to vibration
or sloshing liquids in a vessel.
Note
Use with easy­Drive electric actuator after first being used in other high power application is not recommended.
