PUMP CONTROLS

The following control arrangements are available:

FS-1 (for single unit) - one float switch for start-stop control.

FS-2 (for duplex unit) - two float switches for start-stop control. The switches can be manually set to change the lead pump. Both pumps will operate if the in-flow rate requires.

FS-3 (for duplex unit) - one altemating float switch which operates the two pumps on an alternating basis and turns on both pumps simultaneously if the in-flow rate requires.

FS-4 (for duplex unit) - one altemating float switch (as described immediately above) plus two-pole emergency auxiliary float switch which will tum on both pumps at a predetermined high water level if the alternating float switch fails to operate for some reason.

FS-5 (for single or duplex unit) - a compression tube type high water alarm actuating switch with integral alarm horn. Can also provide signal for remote alarm indication. Alarm panel with bell, indicating light and silencing button is also available.

FS-6 (for single or duplex unit) - one float switch to act as a high water alarm actuator instead of the compression tube type described immediately above.
