Hunter IC-600M - CONNECTING A FLOW SENSOR (OPTIONAL)

CONNECTING A FLOW SENSOR (OPTIONAL)
The I-Core is designed to operate primarily with the Hunter HFS Flow
Sensors. However, some non-Hunter ow sensors can be used.
1. To connect a Hunter HFS Flow Sensor, route the pair of 18 AWG
(1 mm) wires from the sensor into the cabinet (max distance of
1,000 ft.).
2. Locate a pair of S1 or S2 (S3 available on I-Core Metal) sensor red and
black terminals on the Power and Accessories Terminals. Remove the
jumper wire from one pair or S1 or S2 terminals. You may use either
pair of S1 or S2 sensor terminals for a ow sensor. Connect the red
wire from the HFS to the red terminal, and the black wire from the HFS
to the black terminal.
3. I-Core allows you to connect two ow sensors at one time. In that
case, one of the ow sensors would connect to the red S1 terminal
and the black S1 terminal, while the second ow sensor would
connect to the red S2 terminal and the black S2 terminal.
NOTE: I-Core has only one Pump/Master Valve output.
If 2 ow sensors are used on 2 different points of
connection, only one of them will have a master valve
available for alarm shutdowns unless the single PMV is
congured to operate 2 master valves simultaneously.
Flow setup, learning, and conguration will be described later in the manual
under Advanced Features (pg. 22). A complete step by step Flow Monitoring
procedure is also available in the Hidden Features section (pg. 29).
NOTE: If a ow sensor is going to be connected to the
controller and ow will be monitored, there is critical
information that needs to be read in the Controller
Diagnostics and Troubleshooting section under System
Status Dashboard Flow. It is very important to
understand how the controller will monitor ow under
certain circumstances and what diagnostic testing will
be performed in alarm situations.
