Details are given below:
• In case any one of the 2 fans fails (open circuit, short circuit, low RPM), buzzer alarm
will be sounded and front panel Red LED “fan failure” (6, fig 2.1) will be lighted. At
the same time, alarm signal will be provided for remote signaling (Pins 12 and 19 of
DB-25 Connector at the back of the unit - 12, fig 2.1).
• One of the Power supply Modules has a Temperature Sensor mounted on its heat
sink. If the fans are operating normally but the ambient temperature of cooling air is
higher than 40°C and the unit is operating at full load, the temperature of the heat
sink will rise. When the temperature exceeds allowable threshold, buzzer alarm will
be sounded and front panel Red LED “fan failure” (6, fig 2.1) will be lighted. At the
same time alarm signal will be provided for remote signaling (Pins 12 and 19 of DB-
25 Connector at the back of the unit - 12, fig 2.1).
