A Sip and Puff input.
Make sure that all SID connections to the Omni2 are securely mated.
Route and secure all cables and tubes in such a way as to prevent damage by crushing, cutting or snagging.
6.2 USER SWITCH
This input will accept a normally-open switch, a normally-closed switch or a switch incorporating a resistor network. Refer to
the User Switch section in the Programming chapter for further details. For a truly fail-safe system, Curtiss-Wright recommend
that a User Switch incorporating a resistor network is fitted. If one of these is unavailable, a normally-closed User Switch
should be used. This ensures that if the switch becomes accidentally disconnected, the powerchair will default to a stop
condition. If a normally-open switch is used, the responsibility for that decision lies with the healthcare professional.
As a further level of safety, the Omni2 can also detect if the User Switch jack is not properly located. If it is detected that the
jack is not secure, then drive will be prevented. Alternatively, the Omni2 can be programmed to allow slower drive in this
situation, i.e. a limp home facility, or to allow full drive. Refer to the Switch Detect section in the Programming chapter for
further details.
WARNING (HP, IN)
For a truly fail-safe system, Curtiss-Wright recommend that a User Switch incorporating a resistor network is fitted. If one
of these is unavailable, a normally-closed User Switch should be used. This ensures that if the switch becomes accidentally
disconnected, the powerchair will default to a stop condition. If a normally-open switch is used, the responsibility for that
decision lies with the healthcare professional. Curtiss-Wright accept no liability for any losses resulting from the use of a
normally-open User Switch.
WARNING (HP, IN)
Because a disconnected User Switch means there is no emergency-stop function, Curtiss-Wright recommend that Switch
Detect is always set to On. Curtiss-Wright will accept no liability for any losses resulting from any other setting of this
parameter.
6.3 D-TYPE CONNECTOR
Ensure the connector is correctly inserted and if there are locking screws ensure they are fully tightened.
Some SIDs will have a ‘detect-link’ fitted. This link enables the Omni2 to detect if the D-type connector has become
disconnected. The Omni2 will need to be programmed to look for a ‘detect-link’. Refer to the 9-way Detect section in the
Programming chapter for further details. To enhance the system safety and to ease diagnostics, it is recommended that this
feature be used if the SID has such a link. If this feature is used and the Omni2 detects the SID is disconnected, a screen as
below will appear.
