4.4 LED Indications
Functions of front panel LED indicators
LED Colour Function
green
INPUT OK - Mains input voltage okay
(criteria: 195V
AC ≤Vn ≤265VAC)
green
OUTPUT OK - Vout ok (criteria: Vout ≥97% of adjusted value)*
red
Vout > (criteria: Vout ≥ than adjusted operating threshold)*
red
ALARM - Collective alarm**: Vin incorrect, Vout incorrect, module
overtemperature, fan failure and short circuit
*For factory set output voltage threshold values, see section 4.6
**The module is equipped with an isolated signalling contact (normally open contact).
The maximum load is 60V
DC/500mA. The contact is time-delayed and reacts after approx. 10 sec.
4.5 Internal Monitoring
Monitored values Criteria Function
I.) Mains input voltage 164V≤ Vn≤ 195V
Linearly decreases output power.
II.) Mains input voltage <164V
Module automatically switches off.
III.) Mains input voltage >184V
Module switches on.
AC input voltage
IV.) Mains input voltage >275V
Module switches off (self-locking). It
must be manually restarted.
DC output voltage
Output voltage higher than the
adjusted operating threshold*
Module automatically switches off (self
locking). The unit must be manually
restarted.
Module
temperature
Heat sink temperature ≥80°C
Module automatically switches off. It
automatically switches on when the
heat sink cools down to ≤70°C.
Cooling fan Cooling fan malfunction
Module automatically switches off.
After 30 sec. the module automatically
tries three times to restart. If this fails,
the module switches off and must be
manually restarted.
Short circuit
Module automatically detects short
circuit operation by the output voltage
value. (criteria: Vout ≤83% of Vnom)
Module automatically switches off after
3 seconds. After 30 seconds the
module automatically tries to restart
repeatedly.
*For factory set output voltage threshold values, see section 4.6
