SJE-Rhombus NEX Series
control panels are designed to operate in a three fl oat
system as standard. When all fl oats are in the open
or OFF position, the panel is inactive. As the liquid
level changes and closes the stop fl oat, the panel re-
mains inactive until the start fl oat closes. At this point
the pump will start, providing the HOA switch is in the
AUTOMATIC mode and the power is ON. The pump
will remain ON until both the stop and start fl oats open
(return to the OFF position). If the liquid level travels
beyond both the stop and start fl oats and reaches the
alarm fl oat, the alarm will be activated. The alarm horn
can be silenced by pressing and releasing the test/
silence switch.
Alarm System (Horn and Indicator)
When an alarm condition occurs, a red light and horn
will be activated. If the test/silence switch is pressed
and released, the horn will be silenced. When the
alarm condition is cleared, the alarm system is reset.
The alarm system can be tested by pressing the test/
silence switch.
HOA Switch
A hand-off-automatic switch is provided for the pump.
In the hand mode, the pump will turn on. In the auto-
matic mode, the pump will turn on from commands by
the fl oat switches.
Pump Run Light
The run light will be ON in either the hand or the auto-
matic mode when the pump is called to run.
