3.
HV ENABLE switch, active regardless of the operating
mode selected. To power on the HV from the front control
panel, from Remote I/O or from the serial line, the HV
ENABLE switch must be set to the ON position.
4.
HV1 on/off and HV2 on/off buttons, used to
enable/disable the operation of the high voltage circuits.
5.
LEDs; when the ON LED is lit the corresponding HV
circuit is enabled. While when the PROT LED is lit the
Protect operating mode has been selected for the
corresponding pump.
6.
Group of six function buttons with the following functions:
- ENTER button, used to confirm a selection that has
been made with the CHANGE button
- CHANGE CONFIG button, used to display all of the
different options available
- MENU button, used to enter into the configuration
menu
- MODE button, used to select the operating mode
- START PROT 1 and START PROT 2 buttons, used
to select the Start Protect operating mode for the
corresponding pump.
Rear Panel of the E-Net Dual Controller

OPERATING PROCEDURES
Operating Modes
The E-Net Dual Controller can work in the following
operating modes:
•
LOCAL
•
REMOTE I/O (input/output)
•
SERIAL.
In the LOCAL mode all the commands are given
through the front panel.
In the REMOTE I/O mode all the commands are given
from a remote computer through the input/output
connector located on the rear panel.
In the SERIAL mode. All the commands are given from
an external computer through the RS 232 serial line or
by Ethernet.
NOTE
The selected mode of operation is stored by the system
and therefore even if a power failure occurs, when the
power is restored, the E-Net Dual Controller will return
to the mode of operation that it was in prior to the
blackout.
NOTE
When any one mode of operation is selected, the
system will only accept the commands of that related
mode while being able to simultaneously display
information and acquire signals and data from all the
interfaces.
The unit is designed to work in the following modes:
•
START mode
•
PROTECTED mode
In the
START mode
the controller provides all the
power regardless of the pump’s conditions, until
reaching the short circuit current. This mode of
operation must be used to start the pump at High
Pressure.
In the
PROTECTED mode
the controller limits the
output current and switches off the high voltage when
the current exceeds the threshold current for more that
0.2 seconds.
In normal operation, this is the preferred mode, as any
failure of the ion pump or cable due to short circuit or
high load will cause the high current to switch off.
Refer to the appendix entitled “Technical Information"
for detailed information on the modes of operation.
