A.3.2 Alarms
If there is an alarm, the alarm type is indicated by the amplifier’s LEDs. The
LED will blink in different time sequences to indicate which alarm is present
on the device.
The different alarms related to the PA amplifier are indicated by the
sequences indicated below.
On the ALARM LED:
•
Forward Power Alarm: There is not direct power or it is very low. The
alarm sequence starts with one small blink followed by one longer blink.
•
Reverse Power Alarm: The reverse power is too high, please check the
antenna connectors and cables. The alarm sequence starts with 2 small
blinks followed by one longer blink.
•
Voltage Alarm: The voltage is too high or too low, please check POWER
DC LED. The alarm sequence starts with 3 small blinks followed by one
longer blink.
•
High Temperature Alarm: The temperature is too high. The alarm
sequence starts with 4 small blinks followed by one longer blink.
On the POWER DC LED:
•
While the LED is continuously ON in green, there is no alarm.
•
If the LED blinks slowly, the input power is below the DC power supply
range.
•
If the LED blinks fast, the input power is above the DC power supply
range.
• When the LED remains switched off for long, but sometimes blinks. It
means that the amplifier has been switched off remotely by the UDT-4K
or by the RTC-03 Remote Control.
Anyway, when the POWER DC LED is on, the amplifier is powered.
HIGH TEMPERATURE Protection:
The amplifier, as protection against overheating, checks the operation of
the fans. In this way we protect the amplifier from breakage by
overheating. The alarms for breakage of fans will behave as follows:
•
If one fan stops working, High Temperature alarm is displayed on both
the transmitter and the ALARM LED of the amplifier.
•
If the two fans stop working, as a protection measure the amplifier will
turn off automatically, to avoid any overheating.
