With the RS 232/485 connected, a bi-directional
communication is established by selecting HOST. Data are
sent to an external computer every time the external
computer asks for the values.
The available data are listed in the read mode in the serial
protocol table.
NOTE
With the serial module installed, the data can also be
read in the FRONT or REMOTE mode.
If PRINT is selected and a printer is connected on RS 232
line, an unidirectional communication is established and
every minute the data are sent to the printer, even if the
pump is not running.
The set of data available are:
•
Pump speed Hz
•
Pump
temperature
•
Pump current A
•
Pump power W
•
R1
condition
•
R2
condition
•
Confirm the selection by pressing the PUMP
CURRENT push-button.
•
In this way you enter into an operating phase named
"Monitor Relay Programming" described later.
