Wiring a Pump Start Relay
1. Power off the two-wire when installing devices. Leave 24 to 36 inches of slack on the two-wire to allow for
easy installation and maintenance.
2. Locate the biCoder near the irrigation pump relay.
3. Connect the red and black wire from the biCoder to the corresponding red and black wires on the two-wire
using 3M™ Direct Bury Splice Kit DBR/Y connectors. It is critical that polarity be maintained.
4. Connect one gray wire from the biCoder to one wire of the 24 VAC transformer and the other gray wire to one
side of the pump start relay coil using a 3M™ Direct Bury Splice Kit DBR/Y connector. The pump start relay
must have a 24 VAC coil.
5. Connect the other wire from the transformer to the other side of the pump start relay coil.
Note: You must purchase a 24 VAC transformer separately.
6. Configure the biCoder as a Master Valve/Pump Start and test its operation. Refer to Configuring a Master
Valve/Pump Start biCoder on page 41.
Wiring a Flow Device
Water flow sensors measure the velocity of the water moving past the sensor and turn this velocity into pulses per
minute. The BaseStation calculates the flow rate (the pipe size is accounted for in the K-value and Offset), and
provides an approximate water used number.
Water meters measure the amount of water that flows through the meter and turns this into pulses per gallon,
providing an accurate measurement of the amount of water used. The pulses are measured over time intervals
from which an approximate flow rate is calculated.
The Baseline BL-5304 Flow biCoder was designed to work with water flow sensors, and flow sensors provide the
most accurate flow readings. You will see the best results with flow devices that generate more than 100 pulses
per minute.
1. Power off the two-wire when installing devices. Leave 24 to 36 inches of slack on the two-wire to allow for
easy installation and maintenance.
2. Locate the flow biCoder next to the flow sensor/water meter.
