The following controls and indicators are located on the DPM 4000's front panel:

1.LED DCF 77

This LED indicates the operation mode of the DCF 77 radio-controlled-signal receiver. The following table shows the different indications and explains their corresponding status:

OFF

No radio control signal detected or no DCF 77 antenna connected. The

 

system clock is quartz-synchronized.

The radio control signal is detected but its reception is jammed. Re-

 

adjusting the DCF 77 antenna or choosing a location with improved

 

reception is recommended.

2.LED READY

This LED indicates the operation mode of the PROANNOUNCE System. After switching the power on, the READY LED blinks while the system boots. Depending on the complexity of the installation blinking can take several seconds. After successful initialization, the LED lights, signaling that the system is ready for operation. Whenever erroneous operation – either in the DPM 4000 or in one of the connected components – is detected, the LED goes out indicating that a system error occurred. When the system power is OFF, the READY LED is OFF as well.

3.LED POWER

This LED lights as soon as a power source (24 V =, power supply or battery) is connected to the DPM 4000. The LED does not light when the DPM 4000's power supply is disconnected, switched off or fails.

4.LED FAULT

This LED lights during a reset or when an internal watchdog error is being detected within the DPM 4000. It also indicates erroneous operation of external system components (power amplifiers, paging stations, relay boards, ...). The LED is connected to the READY relay on the rear of the appliance, which allows remote indication of system errors.
