When troubleshooting the MAWS system, make sure you have the tools
listed in Table 21 on page 166 available.
Follow the procedure below to troubleshoot the MAWS system. Refer
to the applicable sections of this chapter for details when requested. The
basic procedure for troubleshooting assumes that the person has
operating experience of the MAWS system.
1. Check visually the cabling and mechanical structure for indications
of vandalism, dirt, lightning strike damage, or other visible cause
for the problem. Also check that all the connectors are properly
attached. For visual check of the enclosure and the logger, refer to
section Visual Check on page 170.
2. The MAWS system appears to be completely down.
a. Is the green led on the QML201 logger blinking? Refer to
section Determining MAWS Operation Mode on page 172. If
not check:
- Is there sufficient voltage (8 ... 16 VDC) present in the
EXT-DC input of the logger?
- Is there internal battery present? If there is, check it's
voltage. Completely discharged or otherwise damaged
battery can prevent the logger from operating. Refer also
to section Battery Status on page 187.
b. The logger has power but it is not functioning.
- Connect the terminal cable and start the MAWS Terminal
software. To start the terminal connection, refer to
section Establishing Terminal Connection on page 172.
