With the RS 232 connected, a bidirectional
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:
•
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
If PRINT is selected and a printer is connected on RS
232 line, a 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.
The display will be as shown in the following figure.
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 67 KRPM.
The speed threshold will condition the R1 and R2
operation and it is factory-set to 67 KRPM.
Select the first number by pressing the CYCLE
NUMBER push-button, then enter the value by
pressing the PUMP CURRENT push-button.
Do the same for the second number.
After pressing the PUMP CURRENT the second
time, the display will be as shown in the following
figure.
R U N - U P T I M E
S E L : X X h X X m X X s
where: RUN-UP TIME = is the interval time from
start to speed threshold value in hours, minutes,
seconds. Select from 00 to 99 hours, and from 00 to
59 minutes or seconds.
Select the run-up time according to the chamber
volume and/or operating cycle feature by pressing
the CYCLE NUMBER push-button to select the
desired number, then press the PUMP CURRENT
push-button to enter the data.
The run up time is factory-set to:
00h 08m 00s.
