OPERATION OF RESERVE GAS SUPPLY
The Reserve Gas Supply Option provides a means to supply pressure to the system in the event that
both the left inlet and right inlet gas sources have been exhausted. The Reserve Gas Option must be
installed and enabled for this feature to work properly. When the Reserve Gas Option is enabled
(see Section on “Enabling Reserve Gas”) the Medical IntelliSwitch monitors both the inlet pressure
and the pressure sensor coming from the Reserve Gas Supply. If the left and right gas sources have
been exhausted the system will show an alarm condition on the front panel. The system will change
the left and right pressure displays to read “rES” indicating that it is now receiving gas from the
reserve supply. It will continue operating this way until gas is restored to either the left or right inlet.
At that time the Medical IntelliSwitch will resume normal operation and the “rES” message will no
longer be displayed.
If the pressure of the gas from the Reserve Supply drops below its preset value the pressure sensing
switch will deactivate causing the left and right inlet displays will begin to flash.
Monitoring of the Delivery Pressure is maintained while operating from the Reserve Supply.
ENABLING RESERVE GAS SUPPLY
When the Reserve Gas Supply Option is chosen it is necessary to enable the option in the software.
To enable this option perform the following steps:
1. Turn AC power OFF to the system.
2. Open door by loosening the four screws holding it to the cabinet.
3. Using Figure 14, locate DIP switch SW4-2 at the bottom of the electronic circuit board on
the door.
4. Turn SW4-2 to the ON position.
