9. Message Display
When alarm conditions are present, the corresponding words are displayed and will remain displayed until the
alarm condition is corrected, as long as sufficient power is available. When operating on battery power the
battery indicator symbol is shown (see below).
10. AC Power Indicator Light
The green AC power indicator light is illuminated at all times when AC power is plugged in to the P.T.S., both
in on and standby modes. Note that the AC power indicator light remains off at all times when there is no AC
power connected to the P.T.S., even during the startup routine.
11. Alarm Indicator Light
The red alarm indicator light is illuminated when any alarm condition exists. The alarm indicator will remain
illuminated until the alarm condition is corrected, as long sufficient power is available.
12. Battery Indicator Symbol
The battery indicator symbol in the center of the message display (see above) is visible when the P.T.S. is on
and operating on battery power (AC power not connected). When all six segments inside the battery symbol
are darkened, the battery has a full charge. Reducing numbers of darkened segments and low battery alarm
conditions (see Table 2.1) progressively indicate decreasing battery capacity and need for recharging. The
battery indicator symbol disappears when AC power is connected to the P.T.S.
13. Hose Connector
The hose assembly (see below) leading to the tourniquet cuff plugs in to the P.T.S. unit at the hose connector.
The hose connector is a positive locking type that makes an audible ‘click’ when properly connected.
14. Hose Assembly
One hose assembly is supplied with each P.T.S. unit. The male positive locking connector plugs in to the
hose connector on the P.T.S. unit (see above). The female end attaches to the tourniquet cuff. The P.T.S. is
designed, tested, and recommended for use with Delfi and other single port cuffs having Positive Locking
Connectors only. Use the supplied hose assembly only. An adapter is provided with the P.T.S. unit for
connection to calibration equipment.
15. AC Power Receptacle
The AC power receptacle is located beside the hose connector. The P.T.S. is designed for use with the
supplied AC power supply (see below) only; do not use any other type of connection to AC power.
16. AC Power Supply
An AC power supply adapter is supplied with every P.T.S. unit. It is a sealed unit designed specifically for the
P.T.S. Contact Delfi if your power supply needs service or replacement. Plug the locking connector on the
AC power supply cord into the AC power receptacle on the P.T.S. unit (see above), and plug the AC power
cord into a power outlet (see below) whenever using the unit where AC power is easily accessible. The AC
connector can only be inserted one way into the the AC power receptacle on the P.T.S. unit, and locks with an
audible ‘click’ when properly connected. To disconnect, press the black button on the connector and pull it
out.
17. AC Power Cord
An AC power cord with a hospital grade plug is supplied with every P.T.S. unit. Plug the socket end of the
cord into the AC power supply and the plug end into an AC power outlet.
