5.6.1
Memory (logger of events)
The control unit is furnished with a memory unit to keep a log of events. Such events include:
receiving of information about an alarm, warning or failure reported by a gas detector in any
channel,
failure of the control unit itself, its battery or the monitored shutoff valve,
receiving of an external alarm signal.
Historical events are presented on the user manual panel, similar to regular operation of the device (see
details in Section 5). The only difference is consisted in the fact that the indicated information refers to past
(historical) events.
When any historical event is stored in the log, the LED indicator of the
MEMORY
button starts blinking slowly to
indicate that the log is not empty.
If so, the following may happen:
depressing if the button navigates to the mode of the memory viewing, which makes it
possible to display its content (the LED indicator embedded into the button is continuously on),
the log of events can be erased by depressing the
button and holding it for about three
seconds when the mode of the memory viewing is active,
the memory units automatically quits the mode of the memory viewing after 15 seconds or after
second depressing of the
MEMORY
button.
6 Buzzer – an internal sound warner
The EcoAlpa5 Control Unit has an embedded sound warning device, commonly called a buzzer. It is meant
to pronounce a sound signal when intervention of a system operator may prove necessary, for instance in
case of a gas hazard or malfunctioning of any system component.
