Status messages
Statuses of the Connect ECU
– On mode
The Connect ECU switches from On mode to Standby
mode in the following cases:
– If the apparatus has not been moved for an extended
period of time and the system pressure is 0 bar
– If both buttons on the Connect ECU are pressed for at
least 2 seconds and the system pressure is below
6 bar
– Standby mode
When the apparatus is not being moved, the
Connect ECU switches from Standby mode to Eco mode
after 60 minutes.
The Connect ECU switches from Standby mode to On
mode in the following cases:
– When the compressed oxygen cylinder is opened
– When a button is pushed on the Connect ECU for at
least 2 seconds
– When the function key is removed
– When the user breathes from the apparatus. When the
user is no longer breathing from the apparatus, the
Connect ECU returns to Standby mode after approx.
10 seconds.
Even when the Connect ECU is in Standby mode, it
recognises when the user is breathing from the
apparatus. If the compressed oxygen cylinder is
closed or empty, the no-oxygen alarm will be triggered.
– Eco mode
As soon as the closed-circuit breathing apparatus is
moved, the Connect ECU switches back from Eco mode
to Standby mode.
The Connect ECU switches from Eco mode to On mode in
the following cases:
– When a button is pushed on the Connect ECU
– When the function key is removed
– Off
When the batteries are empty, the Connect ECU is
switched off. When new batteries are inserted, the
Connect ECU automatically switches to On mode. An
acoustic signal sounds. Various information and queries
are shown on the display.
In Eco mode, opening the cylinder will not be recognised
and the no-oxygen alarm is deactivated.
The various states of the Connect ECU allow for maximum
operational readiness with minimum power consumption.
Details on the display when turning the apparatus on
The following information is shown when the compressed
oxygen cylinder is opened. Other information and queries are
shown if the Connect ECU is turned on differently
(pushbutton, insertion of batteries, removal of function key).
The following information and queries are displayed in
succession when the Connect ECU switches to On mode:
– Displays the battery charge status
– Queries whether the high-pressure leak test is to be
carried out
– Display of filling pressure for the compressed oxygen
cylinder and the "Remaining time until low-pressure
alarm 1"
Alternatively, pushing the button on the left or right displays
either the "Elapsed time" or the "Temperature".
Use as distress signal unit
The user can trigger a distress signal using the manual alarm
button if the user cannot retreat from the hazard area.
The Connect ECU can automatically issue an alarm if the
user is no longer moving. To do so, the function key must be
removed from the Connect ECU. If no further motion is
detected, a pre-alarm sounds after a defined time (default
setting: 30 seconds). If any movement is detected within the
following approx. 15 seconds, the pre-alarm is cancelled. If no
motion is detected, the main alarm sounds.
Main alarm (motion sensor) The alarm is triggered
15 seconds after the pre-
alarm (motion sensor), once
the pre-alarm (motion sen-
sor) is not acknowledged.
Main alarm (manual) The alarm is triggered when
the manual alarm button is
pressed.
Battery alarm The alarm is triggered when
the charge status of the bat-
tery reaches a critical level
during operation.
1) The value is configurable
Time remaining until low-
pressure alarm 1
The electronic monitoring
system uses the cylinder
pressure and the respiration
to compute the time until the
warning whistle sounds.
A respiration of 30 L/min is
initially assumed. The com-
putation of the remaining time
is then updated once per sec-
ond with the specific respira-
tion (but at least 30 L/min).
Elapsed time The elapsed time indicates
how long the Connect ECU
has been switched on.
Temperature The temperature shows the
ambient temperature of the
Connect ECU.
