E Diagnosis
LED
(yellow)
Helps troubleshooting and indicates the following:
- Current Overload: output voltage below 20Vdc
due to a too high output current,
ready contact is open
- High Temperature: signal for too high capacitor
temperature (>65˚C), charging and buffering is
still possible, ready contact is open
- Buffer Time Expired:
buffering stopped due to discharged capacitors
- Inhibit Active: buffering is blocked by the inhibit
signal

F “Warning”
LED
(red)
- Check Input Voltage:
Indicates a too low or too high input voltage.
The input voltage must be between 23Vdc and
30Vdc to turn-on the output and to start
charging of the capacitors.
- PC-Mode Activated
Indicates, that the PC-Mode (see also section 9) is
activated.

Connector
(plug connector)
- Ready: contact is closed when status LED indicates ready
- Buffering: contact is closed during buffering
- Inhibit: a voltage applied on this input signal disables
buffering (e.g. during service)
- PC-Mode: To activate the PC-mode connect the two pins of
the signal connector together; see also section 9.
D Status
LED
(green)
- Ready: capacitors are fully charged, no failures detected
- Charging: capacitors are being charged
- Buffering: capacitors are being discharged
