Buzzer
The AC uses the buzzer in case of malfunctioning or situations in which the
attention of the user is required. During tests or maintenance it may be
useful to disable the buzzer using this menu.
Generally speaking, it is better to reactivate it during the normal operation
of the transmitter..
Log Mode
The log is a very important feature as it allows the user to know the details
of the alarms and events occurred to the transmitter, even if it is unattended.
It has two modes between which the user may choose. The “Alarms &
Events” mode logs all alarm conditions as well as events such as the local
or remote on/off status changes.
The “Only alarms” mode only logs alarm conditions. It is generally better
to use the Alarms & Events mode, because the log has a higher level of
detail. The “Only alarms” mode should only be used for testing and
maintenance operations, in order to prevent the log to be filled by events
of minor importance.
Remote
Using the RS232 connection on the front panel or the RS485 one on the
rear panel, the AC may be completely controlled from remote, using a
dedicated software. This function may be disabled from the Remote settings
menu. If the remote control is disabled, the parameters of the transmitter
can still be remotely read, but not changed. The REMOTE LED on the
front panel is lit when remote control is enabled, and unlit otherwise.
RS232/RS485
The transmitter can be remotely controlled through the RS232 connection
on the front panel or the RS485 one on the rear panel. It is not possible to
use both connections at the same time, and the desired one must be chosen
from this menu.
Working Timer
The Working Timer counts the seconds in which the transmitter has been
working, i.e. switched on and powered. This screen also allows to reset
the Timer.
