4.4 Internal Monitoring

Monitored values Criteria Function

Vi<: The device automatically switches off

with an adjustable delay time**. It switches on

if the input voltage is in the correct range. The

switch-on voltage is adjustable*.

DC input voltage

Input voltage out of the range of

adjustable thresholds Vi<* and Vi>*

Vi>: The device automatically switches off

without delay time (protection against

overvoltage). It switches on if the input

voltage is lower than the adjusted switch off

threshold*.

AC output voltage

Output voltage higher than adjusted

operating threshold*

Output voltage lower than adjusted

operating threshold*

The device automatically switches off; manual

restart is necessary.

LED “Vo” = OFF; LED “collective failure”= ON

AC output current

>130% Inom

>100% Inom

LED “Io>” = ON; After 3 seconds the device

automatically switches off; automatic restart

after 15 seconds (for 3 times).

After 30 seconds follows an automatic

shutoff; manual restart is necessary.

Overheating;

Cooling fan

function

Internal temperature higher than

adjusted threshold (factory setting)

The device automatically switches off with

delay time. It automatically switches on if the

temperature is lower than adjusted switch on

threshold. LED T> is on.

Additionally the fan voltage and current

characteristic is monitored to detect a

defective fan. This is indicated by a blinking

LED T>.

* Adjustment of the threshold values please see section 4.5 //**Only with the service menu PM2.
