The following functions or data are monitored during operation:
❶ Interface ❷ Piezo speaker ❸ Button with LED ❹ Reset
Blink/Beep code: - Meaning: Monitoring module faulty
If the box is connected to the mains and the LED does not flash once, twice or three times every 5 seconds, the monitoring module is faulty.
Use a thin screwdriver or a bent paper clip to press the reset button ❹ through the small hole next to the button ❸. If this does not help, please contact Sonation to discuss how to proceed.
Blink/Beepcode: 1 Meaning: OpMode 1: Normal operation.
The sound protection hood monitors all important data and functions. This mode is the delivery state. By pressing the ❸ key, the function of the LED and the sound signal can be checked. A short confirmation tone sounds after 5 seconds at the latest.
Blink/beep code: 2 Meaning: OpMode 2: Aging monitoring deactivated.
In normal operation, the aging of the fans is monitored. An alarm sounds when the speed of the fans has permanently dropped by 20%. This alarm is suppressed in mode 2. However, an alarm still sounds if the fans fail completely.
Blink/Beepcode: 3 Meaning: OpMode 3: Aging monitoring + emergency shutdown deactivated
In modes 1 and 2, when a critical exhaust air temperature is reached (default 60°C), when all fans fail, and when a critical overcurrent of the internal socket occurs, the socket is switched off to protect the consumer. In mode 3 this function is switched off.
This mode may only be used if shutting down the pump will cause more damage than if the pump overheats. If this mode is used, the pump must be monitored by other means by the operator.
Blink/Beep code: 2-1 Meaning: Power supply failure
The external power supply has failed.
If you have intentionally interrupted the mains supply, mute the alarm by pressing the ❸ key. As soon as the storage capacitors have discharged, the monitoring module switches off. With the sound signal switched off, this takes approx. 5 hours. If the voltage has not been switched off intentionally, please check the fuse in the device to which the box is connected.
Blink/Beepcode: 2-2 Meaning: Temperature warning (default: T>40°C)
The exhaust air temperature is higher than the set limit.
Make sure that the supply and exhaust air is not blocked, the unit does not produce too much waste heat and the ambient temperature is not too high.
Blink/beep code: 2-3 Meaning: Overtemperature (default: T>60°C).
The exhaust air temperature is higher than the set limit.
The internal socket is switched off for safety reasons (exception: OpMode 3 is selected). Make sure that the supply and exhaust air is not blocked, the unit does not produce too much waste heat and the ambient temperature is not too high. Check the operation of the fans and the insulated unit.
Blink/Beepcode: 3-1 Meaning: Lifetime of fans reached (n < 80% n_new).
Blink/Beepcode: 3-2 Meaning: Fan failure or too low speed (n < 700 rpm)
If the speed of one or more fans drops below 700 rpm, this alarm is issued. Make sure that the fans are not blocked.
Blink/Beep code: 3-3 Meaning: Failure of all fans
If all fans fail, this error code occurs. To prevent the insulated unit from overheating, open the front door of the sound insulation module. The rear part should be replaced immediately.
Blink/Beepcode: 1-2-1 Meaning: Configuration error
The number of power supplies, temperature sensors and fans is programmed into the monitoring module at the factory. This error indicates an invalid configuration. Please contact Sonation to discuss how to proceed.
Blink/Beepcode: 1-2-2 Meaning: Discharged or faulty buffer capacitors
After connecting the supply voltage, the internal buffer capacitors are charged. During the charging process (about 10 minutes) this alarm may occur. If the alarm is still displayed after 10 minutes, please contact Sonation.
Blink/Beepcode: 1-2-3 Meaning: Failure of a temperature sensor
To protect the pumps, all fans are running at full speed. The back unit should be replaced immediately.
Blink/Beepcode: 1-3-1 Meaning: +24V power supply faulty
The internal power supply is faulty. The back unit should be replaced immediately.
Blink/Beepcode: 1-3-2 Meaning: +5V power supply faulty
The internal voltage regulator is faulty. The back unit must be replaced immediately.
Blink/Beepcode: 2-1-2 Meaning: Overcurrent (default: 12A or 19.2A)
The current consumption of the internal socket is monitored. If the current consumption exceeds 12A (for 10A models) or 19.2A (for 16A models) for a longer period of time, the power supply to the socket is interrupted to protect the electronics and the connected pump (exception: OpMode 3 is selected).
