About the interface cards
Digital inputs
The interface card IF-A1 has three parameterisable digital
inputs DI1, DI and DI3(not used, reserved).
DI1/SEL_enable
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.
= 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.
extern
The display indicates, that the device is in external
control by the analogue interface.
DI/Rem-SB
You can switch the power supply output on and off, enable
or block it with this input. Depending on the setting
output, the input DI/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 setting, the power output is directly controlled by the
input DI/Rem-SB. Attention! This can‘t be interrrupted by
the

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).

The power supply output can only be

enabled at least once. By the setting
(see configuration 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.
Note: the power supply output can always (exception: explicit
local mode) be shut down with the input DI/Rem-SB, even
if external mode is not active.

Set
The jumpers DI1-3 on the PCB are used to preset the phy-

Default level defines the logical level of the input if not
wired.
High range selects the high input voltage range for the
input. A „high“ corresponds to a voltage of >9V and a „low“
to a voltage of <5V.
Low range selects the low input voltage range for the input.
A „high“ corresponds to a voltage of >4V and a „low“ to a
voltage of <1V.
Default:
LOW
The input is low active, standby is activated
with a voltage level <1V or <5V (depending
on the jumper setting)
The input is high active, standby is activated
with a voltage level >4V or >9V (depending
on the jumper setting).
