A – LED display
By default, the LED display is used to display the
current flow. With different button combinations,
the LED display can also be used to show the
totalizer value, current setpoint, and Setup menu
options with associated settings. Alarm status
messages may also be displayed.
B – Status indicators
These are four lights that come on in various
situations.
Auto – When lit, the eFlo is in Auto valve control
mode. When not lit, the unit is in Manual valve
control mode.
Alarm – When lit, an alarm is active. This will be
a Low Flow Rate Alarm, a High Flow Rate Alarm,
or a Limit Switch Alarm.
Open – When lit, the valve is driving open.
Drive – When lit, the valve is driving. If this light is
illuminated, but the Open light is not, the valve is
driving closed.
C – Totalizer button
When pressed and held, the totalized flow value
is shown. After being held for a few seconds, the
value will begin to scroll to the left to show the
full totalized numeric value.
D – Up button
When pressed and held, the Up button will increase the flow rate through the inlet connection
by opening the valve. This button can also be used in conjunction with other items, such as
Setpoint and Setup menu options.
E – Setpoint button
When pressed and held, this button will show the current flow setpoint. By default, the setpoint
can be changed manually by pressing the up or down arrow to increase or decrease the setpoint
while the Setpoint button is being held. It is important to note that the setpoint cannot be
manually changed when the eFlo unit is obtaining a remote setpoint from another instrument.
The remote setpoint can be obtained using an analog or digital signal; it will overwrite any
manual input from the user. See the Setpoint Control and Adjustment on page 11 for more
details.
F – Reset button
When pressed and held for five seconds, the Reset button will erase the current totalized flow
value and change it to zero.
