With the RS 232 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 data available are:
•
Speed adjust
•
Pump/controller operating condition
•
Cycle time
•
Pump life
•
Pump temperature
•
Pump current
•
Pump voltage
•
Controller output frequency
•
Cycle number
•
R1 condition
•
R2 condition
•
Life time and cycle # zeroing
•
Configuration parameter readings
•
Configuration parameter setting
Note that the new input value are put in effect only at
the next STOP/START of the pump.
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 KRPM
•
Pump temperature
•
Pump current A
•
Pump power W
•
R1 condition
•
R2 condition
The controller is factory-set to HOST.
•
Confirm the selection by pressing the PUMP
CURRENT push-button.
•
In this way you enter into an operating phase
named "Monitor Relay Programming" described in
the following paragraph.
Monitor Relay Programming
•
The display shows:
S P E E D T H R E S H O L D
S E L E C T I O N : X X K R P M
where: XXKRPM = is the switch point of relay R1 at
the preset turbopump speed, adjustable from 00 to 99
KRPM.
The speed threshold will condition the R1 and R2
operation (see the following cycle diagram] and it is
factory-set to 40 KRPM.
Press the CYCLE NUMBER push-button to select the
first number.
