Analog Output OVP (U
OVPmon
)
Present set point for over voltage protection. Measurement value refers to the rated voltage of the device + 20%.
Example:
EPS/MP at 600 V output voltage, AI adjusted to 10 V, voltage at output U
mon
= 2 V. Signal refers to 600 V + 20% = 720 V.
Present set point: U
ovp
= 2 V
*
720 V ÷ 10 V = 144 V
Monitor Output Voltage (U
Istmon
)
Present measure value point value for output voltage. Measurement value refers to the rated voltage of the device.
Example:
EPS/MP at 600 V output voltage, AI adjusted to 10 V, voltage at output U
istmon
= 6 V.
Present output voltage U
out
= 6 V
*
600 V ÷ 10 V = 360 V
Monitor Output Current (I
Istmon
)
Present measure value for output current. Measurement value refers to the rated current of the device.
Example:
EPS/MP at 100 A output current, AI adjusted to 10 V, voltage at output I
istmon
= 4 V.
Present output current I
out
= 4 V
*
100 A ÷ 10 V = 40 A

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‘.
Soft-Interlock
The Interlock deactivates the unit immediately, when the connection between interlock input (Pin 5) and
+5 V voltage is opened. In this case, the output of the unit cannot be activated, neither by interface nor by front panel.
The difference between Soft-Interlock and Interlock is that a Soft-Interlock does not correspond to the machinery
directives. If the Soft-Interlock is triggered, the unit switches into Interlock-Mode.
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.
D IGITAL O 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.
