External Power
• The RCS requires External Power to operate.
• Connect External Power.
It is expected that the LCD will be dark (“GUI is blank”)
The device is not working because the GUI is blank Programming the
device puts the device in a “reset” state in which a vertical line is present
and the screen is otherwise blank.
• When using the TCE the LCD remains “OFF” and
the GUI is not shown.
Power Cycle
When the device is left in an intermediated state. (e.g., held in reset).
• Unplug External Power, turn off the device, plug
the device back in.
• This is the only way to completely reset the
device and its connection with the test tool.
• Rapid cycling of the switch does not allow for
system to reset.
Hardware Problem – Alarm Condition
Self Check Alarms / Start Up Self Check
• See Ventilator Alarms Section.
Self –Check Alarm (Service Code # 1175) – Internal COMM occurs during
service.
Although this alarm is typical during service, it is not common during
operational use.
• Expect to see SC1175 alarms. These are typically
due to intermittent conditions.
• Power Cycle
After RTC Battery replacement, device frequently resets date or PM Due
alarm returns
• During the battery replacement, the retaining
clip may be bent. Be careful to gently replace
this battery without displacing the clip. The bent
clip may cause an intermittent connection when
the device is transported causing momentary
power interruptions, which reset the date and
trigger a PM due alarm condition.

• Power Cycle needed
• Check USB – PC
• Check USB – Cable
• Check USB – Hardware
• Check TSI COMM (See Test Station)
• Retry to check if communication is established.
USB – Cable
With high use, the USB Cable can degrade due to wear and tear.
• When multiple devices at a station fail due to
communication with the device, check if the
USB cable for wear and tear.
• Replace USB Cable
USB – PC Setup:
Older devices are compatible with USB 2.0.
But on newer PCs, USB 3.0 ports are preferred over a USB 2.0. port (if
available on the PC).
