Table 5. Non-Isolated Analog Interface Signals (ANA option)
7.1.1.
Typical Remote Operation
Set the LOCAL/REMOTE switch (see Item 18 in Figure 2) to the REMOTE position, the
LOCAL LED will extinguish.
If the power supply also features a Digital interface option, then set the DIGI TAL/ANALOG
switch (see Item 20 in Figure 2) to the ANALOG position, the ANALOG LED will illuminate.
The power supply can now be controlled via the analog interface (see Item 4 in Figure 2),
with the output voltage and current levels set by 0-10V signals, and HV ON/OFF function
by switches or relay contacts.
Some examples for operating the unit in various combinations of LOCAL and REMOTE
modes are shown in sections 7.1.2 through 7.1.4.
7.1.2.
Remote HV ON/OFF with LOCAL voltage/current controls (ANA option only)
Connect a switch between Pin 12 and Pin 6 to turn HV ON/OFF (closed=ON, open=OFF).
Hard wire Pin 5 to Pin 15 and Pin 4 to Pin 8. This setup allows the HV Output to be turned
ON and OFF remotely, but the front panel potentiometers still set the output voltage and
current. This connection will only work with the non-isolated analog interface option (ANA
option).
7.1.3.
HV Output is always ON, REMOTE Voltage and Current programming (ANA
option only)
Hard wire Pin 12 and 6 to turn ON the output. Connect 0-10V to Pin 8 to program the output
voltage, and 0-10V to Pin 15 to program the output current. The internal 10V reference (Pin
10) can be used with external potentiometers to generate the program signals.
7.1.4.
HV Output is always ON, REMOTE Voltage programming, Current set to 100%
rated value
Hard wire Pin 12 and 6 to turn ON the output. Connect 0-10V to Pin 8 to program the output
voltage. Hard wire Pin 15 to Pin 10 to set the current to 100% of rated.
