2 DETAILS OF ALL OMNI2 PROGRAMMABLE PARAMETERS
The following sections explain the effect of all the Omni2 programmable parameters.
2.1 GLOBAL – SIP AND PUFF
2.1.1 PUFF THRESHOLD
This sets the threshold point between soft and hard puffs.
The programmable range is between the value of Deadband and 100% in steps of 1%.
2.1.2 SIP THRESHOLD
This sets the threshold point between soft and hard sips.
The programmable range is between the value of Deadband and 100% in steps of 1%.
2.1.3 DEADBAND
This sets the size of the sip / puff’s neutral area. In other words, how much pressure the user must apply with either a sip or a
puff before the solenoid brakes are energized and drive commences.
The programmable range is between 5% and 50% in steps of 1%.
2.1.4 PUFF RAMP UP
This sets the time allowed to ramp up to a hard puff from zero pressure.
Whenever a hard puff is attempted, there is a period of time when the pneumatic pressure is below the Puff Threshold. This
could be falsely interpreted by the Omni2 as a soft puff command. Different users will have differing abilities in terms of how
quickly they can generate sufficient pressure to pass this threshold. Puff Ramp Up allows the user more time to reach the Puff
Threshold. If this threshold is not reached within the Puff Ramp Up time, a soft puff will be interpreted, provided the pressure
is above the value set for Deadband.
The programmable range is between 0ms and 2000ms in steps of 50ms.
2.1.5 PUFF RAMP DOWN
This sets the time allowed to ramp down to zero pressure from a hard puff.
When a hard puff has finished, there is a period of time when the pneumatic pressure is below the Puff Threshold but still
above the value for Deadband. This could be falsely interpreted by the Omni2 as a soft puff command. Puff Ramp Down
allows the user sufficient time to reach the Deadband without unintentionally providing a soft puff. If this Deadband is not
reached within the Puff Ramp Down time, a soft puff will be interpreted, provided the pressure is below the Puff Threshold.
The programmable range is between 0ms and 2000ms in steps of 50ms.
