PS 2000 B Triple Series
3.5 Remote control
3.5.1 EA Power Control
The included USB stick contains the Windows software EA Power Control which can remotely control the device.
Also see the user manual of the software.
3.5.2 Programming
Programming details and the communication protocol are to be found in the programming documentation which
is supplied on the included USB stick or which is available as download from the EA Elektro-Automatik website.
3.5.3 EasyPS2000
The Windows software EasyPS2000, as offered for the former PS 2000 B design generation with blue LCD, is
still available and can also be used with the new design generation with color TFT, but it would still depict the
counterfeit of the old design.
3.6 Alarms and monitoring
3.6.1 Device alarm and event handling
A device alarm incident will usually lead to DC output switch-off and the appearance of a
text message in the display to make the user aware. Some alarms must be acknowledged.
If the condition persists, the display remains and the alarm can only be acknowledged
after elimination of the cause.
► How to acknowledge an alarm in the display (during manual control)
1.
Once an alarm is indicated, the user can try to acknowledge and delete the alarm by pressing button
On/Off
.
In order to acknowledge an alarm during remote control, see the programming guide.
These device alarms are configurable:

Triggers an alarm if the DC output voltage reaches the
defined threshold. The DC output will be switched off..

► How to configure the device alarms
1.
While the DC output is switched off, press button Settings .
2.
In the menu use the left knob to navigate to Settings and press the knob.
3.
In menu Settings use the left knob again to select OVP (threshold of the overvoltage protection) or OCP
(threshold of the overcurrent protection). Adjust the value as desired.
These protection threshold are always adjustable in their full range of 0...110% of the rated val-
ue. The device permanently compares the actual voltage and current on the DC output against
these thresholds and thus an OVP alarm could also occur while the DC output is switched off.
In this situation the voltage that triggers the OVP must come from outside and could damage
the device.
