Commander LI90 Multi-Tank Level Controller
The general purpose level controller displays engineering units with four 4-20 mA continuous level sensor inputs and 6 programmable relays. Select from one of three run configurations including multi-tank with 4 level sensor inputs and 4 relays; or pump control with 1 level sensor input and 6 relays for lift stations in simplex (one pump) or duplex (two pumps) level control modes; or differential level with 2 level sensor inputs and 4 relays for municipal screen or rake control. Relays can be configured on a single set point (high or low level alarm) or latched on two set points for automatic fill or empty pump or valve control with selectable time delay. The graphic LCD display indicates span and relay status for each input channel. The optional MicroSD card enables data-logging storage and retrieval.
