3.3 Field of Application
3.3.1 General
use
The leak indicating unit has three input channels.
Each channel has two terminals. When connected, a signal circuit is
closed between the terminals.
If the signal circuit of the respective channel is closed, the leak indi-
cating units is in good state. If the signal circuit is interrupted, the
alarm is triggered at the LAE.
Note:
Unused channels in the leak indicating unit must be bridged.
The connection devices with their potential-free relay contacts are
connected to the terminals of a channel. It is also possible to connect
several devices in series to one and the same channel.
If a connected device leaves its (good) operating state, its potential-
free contact opens and the signal circuit is interrupted. In this way,
both alarms and cable breaks are detected.
In the event of an alarm, the internal buzzer sounds on the leak indi-
cating unit and indicator lights on the keypad light up.
The following applies to the alarm display on the keypad:
Alarm on channel 1: Red LED (high priority)
Alarm on channel 2: Yellow LED (medium priority)
Alarm on channel 3 red + yellow LED (low priority)
