Part 5 Field Settings and Test Operation
Automatic night-time low noise setting and level during night-time
By changing this setting, you can activate the automatic night-time low noise
operation function of the unit and define the level of operation. Depending on the
chosen level, the noise level will be lowered (3: Level 3 < 2: Level 2 < 1: Level 1).
The start and stop moments for this function are defined under setting [2-26] and
[2-27].
Default value: 0
Change [2-22] to 1, 2 or 3 in function of required level.
Night-time low noise operation level via the external control adaptor
If the system needs to run under night-time low noise operation conditions when an
external signal is sent to the unit, this setting defines the level of night-time low noise
that will be applied (3: Level 3 < 2: Level 2 < 1: Level 1).
This setting will only be effective when the optional external control adaptor
(DTA104A61/62) is installed and the setting [2-12] is activated.
