Commissioning Functions
The 4LSL measuring module includes additional commissioning and servicing
aids to better control the measurement equipment or the loudspeaker circuits.
These are:
- Switchable drive display (VU meter) to check precisely all signals to be meas-
ured
- Display of the most important functions on the front plate
- Automatic or manual calibration of loudspeaker circuits
- Diverse group and individual messages
- PC-based configuration
- Measurement data transmission to the DVS-21 central system
- Simulation of all processes which the module has
Summary of the Functions
- Precision measuring for impedance error detection: 1-100% in 1% steps
(% of installed loudspeaker load)
- Number of independent loudspeaker circuits or measurement channels:
4
- Measurement channels can be individually switched on/off
- Loudspeaker
minimum/maximum load per channel: 2.5 Watt / 150 Watt
- Loudspeaker load check during commissioning
- Manually or automatically configurable impedance deviation limits
- Verification of impedance deviation through automatic multiple subsequent
measurements
- Automatic or manual measuring procedure
- Checking of the test signal generator before each measurement
- Wire breakage or short circuit detection
- Allocation of an occurring earth leakage to a loudspeaker circuit (earth leak-
age detection through TG01)
- Transfer of all measurement data to the DVS-21 central system
- Display of all statuses by LEDs on the front plate
- Loudspeaker circuit relays: 4 (1/channel)
- Generation of positive and negative public address acknowledgements
- Programmable night-reduction function for public address acknowledgement
- Configurable amplifier protection function for loudspeaker circuit short circuit
- Making possible public address in the case of a short circuit (group public
address)
- Diverse group and individual messages
- Full control over all procedures through the DVS-21 central system
- PC-based
configuration
- Commissioning and service aids on-board
Further details can be found in the commissioning instructions.
