Communication
The Communications menu allows the operator to choose the type of RS485 communications such as PVA Gauge,
Modbus or Local Display. The menu also allows for the operator to choose the RS485 slave address, RS485 Serial
setup and whether or not the controller uses the internal CAN terminating resistor. Review Communication under
the Menu Glossary section of this manual for a full list and definition of each setting.
Start/Stop Settings
There are eight automatic start/stop types in the MPC-20. Each is detailed below:
Single Contact Start/Stop
The Single Contact Start/Stop is when a remote contact closes and remains closed for auto start and re-opens for
auto stop.
Two Contact Maintained Start/Stop (commonly known as Floats)
The Two Contact Maintained Start/Stop is when both contacts close for auto start and both contacts open for auto
stop (not momentarily). This may also be reversed by altering menu settings.
Two Contact Momentary Start/Stop
The Two Contact Momentary Start/Stop is when one contact closes momentarily for start and another contact
closes momentarily for stop.
(Level, Pressure, Temperature or Flow) Transducer Start/Stop
A transducer is used for auto throttling and start/stop. There are set points allowing the operator to enter the
appropriate values.
Local Start Key Start/Stop
The Local Start Key Start/Stop is used to remove any other auto start/stop types within the controller if they are
not needed, regardless if in auto or manual modes.
If an auto stop condition occurs during the warm-up delay, the controller will enter an auto stop sequence.
