3.5 Resetting the MS Detector
If communication between the MS detector and data system computer is lost,
it may be necessary to reset the MS detector using the Reset button on the
power panel.
The procedure given here assumes that the MS detector and data system
computer are both powered on and are operational. If the MS detector, data
system computer, or both are off, refer to the topic Starting Up the System
after a Complete Shutdown.
To reset the MS detector, press the Reset button located on the power panel.
See Figure 3-1 on page 3-2 for the location of the Reset button. When you
press the Reset button, the following occurs:
• An interrupt on the CPU PCB of the embedded computer causes the
embedded computer to reboot. All LEDs on the front panel of the MS
detector are off except the Power LED.
•
After several seconds, the Communication LED is illuminated yellow to
indicate that the data system and the MS detector are starting to establish
a communication link.
• After several more seconds, the Communication LED is illuminated
green to indicate that the data system and the MS detector have
established a communication link. Software for the operation of the MS
detector is then transferred from the data system to the MS detector.
• After 3 min, the software transfer is complete. The System LED is
illuminated either green to indicate that the instrument is functional and
the high voltages are on or yellow to indicate that the instrument is
functional and it is in Standby condition.
