PASSWORD MANAGER
This option allows the user to enable/disable Helium gas usage and to erase all PINs to
disable the unit entirely. PINs are supplied to certified users through a student’s instructor.
Upon the sale of the rebreather/electronics to another party, the
handsets should be disabled by clearing all the PINs. The PINs can be
reissued through the proper channels once the liability waivers / releases
and training has been completed.
PRIMARY Handset Options and Programming
SOLENOID FIRING
The solenoid firing function chooses the set-point control
algorithm. The modes are scrolled through by use of the LEFT button
and selected by the RIGHT button. The HammerHead supports two
automatic control methods: “Standard Mode” and “Juergensen Mode”,
plus the non-automatic “Manual Mode”. Standard mode uses the error
setting from “Standard Error”, while “Juergensen Mode” is an adaptive
algorithm that changes firing duration and rate based on error from
selected set-point. “Manual Mode” requires the diver to maintain the
loop PO2, automatic PO2 control is disabled. This function would be
used to override the master when it is suspected that the controller is basing the PO2 control on
bad data. An example of this would be two cells agreeing, while a third cell does not agree and
the diver determined that the third cell is the correct one. The handset will override the manual
setting and fire the solenoid if the loop PO2 drops to a 0.19.
