The IN # 2 Input
This input is activated when closed. Activating
this input while Program mode is selected, causes
File 13 to run. If nothing is programmed in File 13
or if File 13 is already running, this input will be
ignored. This input can be used to start a special
program if an external signal is received, for
example a warning signal from a temperature
measuring system.
Output Controls
The 305 Master pump has three output relays.
Each output relay consists of two terminals.
These terminals can be connected together (contacts
closed) or not connected together (contacts open).
All of the outputs are electrically isolated from each
other and from ground. These contacts can be used
to control other equipment, e.g. to turn on or off
another piece of equipment.
