5.3.3 Output Voltage Low

Output voltage low monitoring; signalling with green LED "Vout>Vmin",
Criterion: output voltage is higher than adjusted level V<;
This signal has its own relay contact on signalling connector. If the voltage value is O.K. Pin 6 and Pin 7 of X2 are
closed.

5.3.4 Output Voltage High

Output voltage high monitoring; signalling with red LED "Vout>",
Criterion: output voltage higher than adjusted level V>;
This signal is included in collective failure signal of rectifier. If there is an error the LED is switched ON and the recti-
fier internally switches OFF. You have to reset the unit by ON/OFF switch.

5.3.5 Protection against Overheating

Protection against overheating; signalling with blinking red LED "Bell symbol", criterion: temperature of heat sink >
90°C. This protection reduces the output power if the temperature is on the limit. This signal is included in collec-
tive failure signal. If the temperature is normally the output power will be increased automatically.

5.3.6 Signals

The signals "V OK", "Mains OK" and "Constant Current Mode Iconst" are opto coupler signals with a loading of 30
O
V/5mA. The opto couplers switches off at error. The collective failure signal is delayed for approx. 1sec. The relay
contacts between Pin 3 and Pin 5 of X2 are open and between Pin 4 and Pin 5 are closed at error.
