STEP 2: Wire the Controller
The extent of wiring needed will depend on your
application and if your unit comes with a power cord and
pigtails. Refer to the wiring diagram below (Fig# 2) which
is also available on the inside of the controller door.
WARNING: Be sure to connect all wiring without
power applied to the controller. Failure to do so
may result in incorrect measurements.
The terminal board has the following sections:
1
Line Power: This includes input power, pump relays,
blowdown valve, and alarm relay. Wire the line, neutral,
and ground wires for each relay being used. For the
blowdown relay, ensure you wire to the normally open
and/or normally closed terminal depending upon the
type of blowdown valve connected.
2
Sensors: Use this section to connect various sensors -
pH, conductivity, ORP, temperature.
3
Flow Meters: Connections are available for makeup
and blowdown flow meters. 24 volt DC power is
available for flow meter or other device that needs
power.
4
Flow Switch: For applications that require flow
detection, wire the flow switch here after removing the
supplied jumper. Otherwise, leave the jumper in place.
5
Low Tank Sensor: Four low tank sensor connections
are available.
6
4-20 mA Outputs: Two outputs are intended for data
logging on devices such as chart recorders. Sensors
can be configured to these outputs.
7
Pulse Pacing: Two outputs may be connected for
pulse control of pumps. Pumps must be powered from
