AO3 Default: 0.00V 10.00V
= PMON Monitor (actual value) output power
These extra settings are only available for PSI 9000 series
models:
{Nom.value | Adj.limits} Default: Nom.value
= Nom.value the dened range for VMON, CMON and
PMON is always related to the nominal
values of the device (see section „Expla-
nation about Nom.value“ above)
= Adj.limits the dened range for VMON, CMON and
PMON is always related to the adjust
limits of the device (see section „Expla-
nation about Adj.limits“ above)
Note
For PSI 9000 series models it is recommended to keep the
setting „Nom.value / Adj.limits“ the same for both, analogue
inputs and outputs.
Note
The maximum output voltage, current and power can
additionally be limited by adjustment limits. See the user
instruction manual of your device, menu item „Prole ->
General settings -> Adjust limits“ for further details.
7.3.3 Digital inputs
The interface card IF-A1 has two parameterisable digital
inputs, DI1 and DI2.
DI1/SEL_enable Default: LOW
external
= LOW External control of the device by IF-A1 is low
active. If the default logical level of DI1 is set to
LOW by the jumper on the PCB, the external
control will be instantly active when switching
the device on and condition is not „local“.
= HIGH External control of the device by IF-A1 is high
active.
After the external control has been actived, the power supply
can be controlled by the inputs VSEL, CSEL and/or PSEL.
The status signale and analogue actual values are always
put out.
About the interface cards
Input DI2/Rem-SB
You can switch the power supply output on and off, enable
or block it with this input. Depending on the setting Set
output, the input DI2/Rem-SB determines whether the out-
put is controlled exclusively in external mode (by analogue
interface) respectively remote mode (by digital interface) or if
it requires to be enabled by the ON/OFF key. The enabling is
indicated in the display with auto ON. Using the exclusive
On/Off setting, the power output is directly controlled by the
input DI2/Rem-SB. Attention! This can‘t be interrrupted by
the ON/OFF key on the front or by a command from a digital
interface card. Exception: the device is in „local“ mode, then
the input is ignored.
DI2/Rem-SB
Set output Default: enable ON
= enable ON The ON/OFF key has to be used to
enable the input
= exclusive The power supply output can only be
switched on and off by the input DI2/
Rem-SB
When using the setting enable ON, the output needs to be
enabled at least once. By the setting Power ON = restore
(see conguration menu of your device) the power output
will be automatically enabled after a mains loss, if it has
been enabled before the mains loss occured. It can then be
switched on or off as normal.
Standby Default: LOW
= LOW The input is low active, standby is activated
with a voltage level <1V or <5V (depending
on the jumper setting)
= HIGH The input is high active, standby is activated
with a voltage level >4V or >9V (depending
on the jumper setting).
The figure shows the chaining of the various states and con-
ditions for local, remote and external mode when switching
the power output on or off:
