7. Input/Output Setup
Use the “DIGITAL I/O” menu to activate the functions required for the intended application.
Users may also reference Section 12 – Menu Maps for additional configuration assistance
7.1 Analog Input Setup
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.
Note that Analog Input #2 is not yet available for use, the MPC accepts only one incoming analog signal
at this time.
7.2 Digital Input Setup
Each of the 2 Digital INPUTS can be selected as: Inactive
Leak Detection
Tank Level Input
Remote ON/OFF Input
Flow Detection (delay time must be set)
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.
7.3 Analog Output Setup
Use the “ANALOG I/O” menu to activate the analog output signal function.
The menu can be used to set the analog output to either ACTIVE or INACTIVE.
7.4 Digital Output Setup
Each of the 3 Digital OUTPUTS can be selected as: Inactive
ON/OFF Status
AUTO/MAN Status
Stroke Indicator (Pulse Output)
Alarm Indicator
Leak Detection Status
Tank Level Status
Each can be set as normally OPEN or normally CLOSED. For example, if an output is set to ON/OFF
INDICATION and NORMALLY CLOSED, this means that when the motor is running (indicator lamp
is ON) the output will be CLOSED. A NORMALLY OPEN setup will give the opposite response.
Digital output circuits are transistor based and limited to 40 VDC maximum, see Section 5.3.4,
Input/Output Signal Wiring, and Section 11, Specifications, for more information).
