Flowmeter Input Flowmeter Input Flowmeter Input Flowmeter Input Flowmeter Input
The inputs are reversible when the flowmeter connection is a relay and has no
polarity

Flow Switch Input Flow Switch Input Flow Switch Input Flow Switch Input Flow Switch Input
This input can be used to connect a flow switch or other device providing a switch
closure output. If a device such as this is connected to the DC4500, it will serve
to disable the controller outputs when this switch is in the “OPEN” position.
This function can be used as a safety override to prevent controller/pump
operation during loss of flow.
The inputs are reversible since the flow switch connection has no polarity.
