Monitor Output Voltage (U
Present measure value point value for output voltage. Measurement value refers to the rated voltage of the device.
Example:
LAB/HP/E at 600 V output voltage, AI adjusted to 10 V, voltage at output U
Present output voltage U = 6 V
out
Monitor Output Current (I
Present measure value for output current. Measurement value refers to the rated current of the device.
Example:
LAB/HP/E at 100 A output current, AI adjusted to 10 V, voltage at output I
Present output current I = 4 V

The digital inputs can be used to adjust the operation mode for the analog control. Inputs are low active.

Activation (Ext. Control)

The input ‚Ext. Control' can be used to chose the operation mode ‚AI'. The AI interface is activated by an applied
voltage of + 5 V up to + 10 V. Front panel operation is deactivated. Operation mode is marked as ‚AI' on the display.
The digital interface takes priority over the AI interface. The settings from AI interface have no effect if the device is
toggled to ‚Remote'.

Blocking (Standby)

The standby mode is activated by an applied voltage of + 5 V up to + 10 V.
The output signal is enabled, if the input ‚Standby' is toggled inactive.

IGITAL UTPUT
On the digital outputs, actual device adjustments are displayed (irrespective of the actual operation mode). Therefore
the AI interface may be used for monitoring functions also. Gauges are consistent with a negative logic: S = Set = log.
0; R = Reset = log. 1
A set output has a voltage level of < 0.6 V. A reset output has a voltage level of > 1.2 V.
Blocking (Standby)
The blocking of the output is set, if the unit is in standby mode.
C . V
ONST OLTAGE MODE
Constant voltage mode is set, when the unit is in constant voltage mode.
E
RROR
An error is set, if the unit has been shut down by OVP. To reset this error, the standby mode must be activated.
