7. Input/Output Setup
Use the “DIGITAL I/O” and “ANALOG I/O” menus to activate the functions required for the intended
application.
Users may also reference Section 14 – Menu Maps for additional configuration assistance
7.1 Analog Input Setup
Two Analog Inputs are provided for the User. Analog Input 1 is used for Setpoint input. Analog Input 2 is
used for systems configured for analog process feedback from a flow meter.
7.1.1 Analog Input 1 – Setpoint
See Figure 4 – Signal Connections to insure that you have your Analog Input signal connected to the proper
location before activating. Use the “ANALOG I/O” menu to activate the analog input signal function. The
menu can be used to set the analog input to either ACTIVE or INACTIVE. The setpoint input should be
calibrated prior to activation (ref. Section 8.2 – Analog Input Calibration).
7.1.2 Analog Input 2 – Flowmeter Feedback
See Section 9 Flow Meter Input for installation instructions. The flow meter input signal must be configured
properly prior to use. Use the “FLOW SENSOR” sub-menu under “SYSTEM SETUP” to enable the process
feedback analog input. The flow sensor type must be set to “ANALOG” to enable this input. The process
feedback input should be calibrated prior to activation (ref. Section 8.1 – Pump Flow Calibration).
7.2 Digital Input Setup
7.2.1 Multi-purpose Digital Inputs
Each of the 2 Digital INPUTS can be selected as: Inactive
Tank Level Input
Leak Detection (using external device)
Remote ON/OFF Input
Flow verification Input
Each can be set as normally OPEN or normally CLOSED. For example, if an input is set to ON/OFF and
NORMALLY CLOSED, this means a CLOSED switch will activate the pump. A NORMALLY OPEN
setup will give the opposite response. These inputs are to be attached to a dry contact circuit only, apply no
voltage to these inputs.
