The input type is where you may choose the type of input that will control the
pump outputs.
• The FLOAT option will use only floats, connected to pump 3 switch inputs
(see Figure 5 on page 9), and will ignore the 4-20 mA input.
• The “4-20 mA” option will use a transducer only and ignore the float
inputs.
• The “4-20 mA → FLOAT” option will use the transducer normally, but
should the signal drop out will revert to floats mode. The signal must
drop below 2 mA to switch to floats mode.
• The “Alarm Float” option, if present, will allow for an alarm float (connected
to the Pump 3 “Spare” input) to be connected that will trigger the alarm
relay should the float activate before the 4-20 mA signal reaches the alarm
point.
• The “Activate Pumps” option, if present, will turn on either 1 or 2 pumps
when the alarm float (Pump 3 “spare”) activates (if set to ON in the above
setting)
If you selected three pumps, the 4-20 mA → FLOAT mode will not be
available.
14) Press Next to continue to set the unit of measure (if FLOATS option was
selected, the next screen will be “CONFIG – ALARM ENABLE”, step 36 below)
15) The UNIT OF MEASURE screen presents the following choices:
• FT FEET
• IN INCHES
• M METER
• PI PSI
This is a cosmetic setting only and shows with the value on the main run
screen (Figure 8), the values do not automatically re-calculate upon change.
16) Press Next to continue to the AI (analog input) configuration
17) The CONFIG – AI – RANGE screen presents the following:
• 4 mA = xx.x FT (or the unit of measure selected above)
• 20 mA = xx.x FT
18) When the selection arrows are pointing to the “4 mA” line, press Selct
19) Use the +1 and -1 buttons, in conjunction with the *10 button, if necessary, to
adjust the low input value. (The *10 button will need to be pressed at the same
time as the +1 or -1 buttons.) This should correspond to the value at which the
sensor is sending 4.00 mA.
20) Press Enter to lock in the value
