2. Locate the Analog Output Connections on the rear of the BioFlo 415 cabinet (see
Figure 47).

3. The preferred connection for pumps is 4-20mA. If you are using a 0-5V
connection, skip to step 5. To use 4-20mA, connect the end of the green cable wire
to one of the three (1, 2 or 3) negative (-) outputs at the bottom. Make sure the dip
switches are set to 4-20mA.
4. Connect the end of the white cable wire to the positive (+) output at the top: be
sure to use the same number (1, 2 or 3) as you used for the green wire.
5. If, and only if, you are using a 0-5V connection instead of 4-20mA, connect the
end of the green wire (return) to one of the four (4, 5, 6 or 7) negative (-) outputs at
the bottom and connect the end of the black wire (0-5V input) to the matching
positive (+) outputs at the top.
6. Set up the pump control loop using a loop for external equipment.
After a pump is added, it will appear on the
CAUTION!
Be sure to set the dip switches correctly (see Figure 47) when using
either 4-20mA or 0-5V inputs/outputs.
