6.1 The display
This is an overview of the two line display and its layout.
The left side always shows actual values while the load
input is switched on:
The
indicator
for the regulation mode(a triangle) appears
next to the actual value, which is related to currently
active regulation mode of the load. This can differ from
the chosen regulation mode if a nominal value has been
exceeded. The current or power limitation have priority
over the voltage or resistance limitation here. That means,
that the load will change into constant current limitation as
soon as the nominal current value has been exceeded.
The triangle indicates this.
In standby (load input off), the status
Standby
is displayed
and only the actual value of voltage is shown:
Figure 4
Various texts in the right half of the display indicate diffe-
rent operation modes or errors:
Figure 5
This text appears if the load was set to remote control
operation (
Remote mode
) via the optional interface card.
This is possible in the modes
Level A
,
B
and
A/B
.
Figure 6
The text
External mode
indicates, that the control of
the load was switched to the analogue interface. The
set values can not be adjusted at the device anymore in
this mode. For detailed information see section „8. The

Handling the device
The texts
Overvoltage
or
Overtemperature
indicate the
status of an error.
An
overtemperature error
occurs if the load gets over-
heated. The load input is switched off and remains as
long the error is persistent. After cooling down it switches
automatically on again.
An
overvoltage error
is indicated if the overvoltage limit
for the DC input has been exceeded (see„2. Technical
specifications“). This error switches the load input per-
manently off. After removal of the cause it can be put
online again.
Alarm management
Error indications now remain in the display until acknow-
ledged by the „Input on/off“ button. The purpose is to
inform the user that an alarm is either active or already
gone. Example:
Figure 7.2
Only the least occured alarm is indicated, but up to three
different alarms are stored in an internal error buffer which
can be read out via one of the digital interface cards using a
specific command. This also resets the display and purges
the buffer.
