When troubleshooting the MAWS system, make sure you have the tools

listed in Table 23 on page 182 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 the cabling and mechanical structure visually 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 186.

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 188. If

not, check the following:

- Is there sufficient voltage (8 ... 16 VDC) present in the

EXT-DC input of the logger?

- Is there the 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 202.

b. The logger has power but it is not functioning.

- Connect the terminal cable and start the MAWS Terminal

software. To establish the terminal connection, refer to

section Establishing Terminal Connection on page 188.
