CONTROLLING THE OUTPUT USING EXTERNAL (ANALOG) SIGNALS (REMOTE)
How do I control the mode using an external signal?
$
, highlight External Mode,
!
, highlight Enable,
$
, then
%
to apply
changes and exit. This setting is not saved for power-up (PAR. 3.4.2). Select mode by applying either logic 1 or open circuit for voltage, or
logic 0 or short circuit for current, to pin 2 referenced to pin 9 of the Analog I/O port (PAR. 3.4.2).
How do I use an analog voltage to control the output (main channel)?
$
, highlight Reference input,
!
, highlight External
then
$
, then
%
to apply changes and exit . This setting is not saved for power-up. Apply ±10V signal to pin 11 referenced to pin 4 of the
Analog I/O port to control active channel (voltage or current) (PAR. 3.4.3).
How do I use an analog voltage to control the protection channel?
$
, highlight Protection Limit,
!
, highlight External then
$
, then
%
to apply changes and exit (not saved for power-up). Apply +1V to +10V signal to the following pins referenced to pin 12 of the
Analog I/O port to control limit channel from 10% to full scale: –Current Protect: pin 5, +Current Protect: pin 13, –Voltage Protect: pin 6,
+Voltage Protect: pin 14 (PAR. 3.4.4).
How do I choose between local, digital and analog control of the output?
The unit normally powers up in Local mode. Sending
a command via RS 232 or GPIB interfaces automatically puts the unit into Remote mode. Press
!
to restore Local mode. If an analog
voltage is controlling the output (see above), local control of the main channel is disabled and digital commands are not accepted.
How do I use the BOP as an amplifier?
See above to control the main channel and/or protection channel using analog signals. The
nominal (inherent) voltage gain of each model is calculated by (G
NOM-V
) = E
Onom
/ E
REF
. and nominal (inherent) current gain is (G
NOM-I
) =
I
Onom
/ E
REF
where E
REF
= 10V (see PAR. 3.4.3.1).
How do I control the gain of the BOP when used as an amplifier?
$
, highlight Reference input,
!
, highlight ExtlRefLevl then
$
, then
%
to apply changes and exit (not saved for power-up). Apply ±10V signal to pin 11 referenced to pin 4 of the Analog I/O port.
Main channel setting (SET) determines gain (G) by G = SET/10 (PAR. 3.4.3.2).
