POSEIDON M28 USER MANUAL
Connection status alarms
As soon as the M28 detects the SE7EN E-module or other devices on the
CAN-bus, such as the HUD or a CPOD, the M28 will begin to monitor their
presence. If contact with a device is lost a disconnection alarm is triggered and
the vibrator and applicable alarm icons are activated together with an on-screen
message telling which device that has been disconnected. In case the M28
detects a previously disconnected device a reconnection alarm is triggered with
an on-screen message telling which device that has been reconnected. In case
several devices are disconnected or reconnected, messages for each device
will alternate on screen. The disconnection alarms may be triggered by cable
failure or failure of the disconnected device. A disconnection alarm may be
followed by a reconnection alarm in case of an intermittent cable failure or an
intermittent device failure.
If SE7EN is disconnected, the M28 will enter Setpoint dive mode, see the M28
manual for details. If SE7EN was congured for non-decompression diving
(deco enable is OFF), the M28 will set Bailout ACTIVE when SE7EN
disconnection alarm is activated. When SE7EN is congured for decompression
diving (deco enable is ON), it is the responsibility of the diver to activate Bailout
mode on the M28 when appropriate. The recommended action in case of a
SE7EN disconnection alarm is to abort the dive in OC bailout mode.
If a CPOD is disconnected, the M28 will change dive mode from CPOD to
Setpoint. At this point Bailout is set to off and it is the responsibility of the diver
to activate Bailout mode on the M28 when appropriate. The recommended
action in case of a CPOD disconnection alarm is to abort the dive in OC bailout
mode.
The recommended action in case of a HUD disconnection alarm is to abort the
dive while carefully monitoring PO2 and alarms on the M28 display.
The recommended action in case of any reconnection alarm is to abort the dive.
Disconnection alarms can be acknowledged at any time. Acknowledging a
disconnection alarm means that the acoustic alarm signals are silenced, the
