Instructions for Using the BL-5201PR to Turn On a Pump Relay — Activating a Normally Open Relay
1. Connect the red and black wires on the biCoder to the red and black wires from the two-wire
path that connects to the controller. Polarity matters! All connections must have DBR/Y or
equivalent connectors.
2. Connect the gray wire from the BL-5201PR biCoder to one wire from the 24VAC transformer.
3. Connect the other wire from the transformer to the relay.
4. Connect the white wire with the black stripe from the BL-5201PR biCoder to the common wire on
the relay.
5. Cap the gray wire with the
black stripe.
6. Configure the BL-5201PR in the
controller.
Wire Descriptions
Red and black wires: Connect to the two-wire path
Gray wire: Normally open wire that is used to turn a relay on or to close a switch
Gray wire with the black stripe: Normally closed wire that is used to turn off a relay or to
open a switch
White wire with the black stripe: Common wire
