triggered data.
• The AL200 is currently connected
to Device Configuration Utility and
data transmissions are being
suppressed.
• The event threshold is not properly
set.
• The AL200 is not currently
measuring a level that exceeds the
event threshold.
• The AL200 has not obtained an
initial GPS fix.
The Test Button is not initiating a

initial GPS fix.
• The AL200 has been configured as
a datalogger peripheral and the test
button functionality has been
disabled.
The AL200 is reporting incorrect

are not correct.
• There is an issue with the attached
sensor or sensor wiring.
The radio LED is always red. • The AL200 has been configured to
keep the radio always on.
The GPS LED is on longer than the
maximum allowed on time.

obtain leap second information and
may be on for up to 13 minutes.
11. Repair
The AL200 is designed to give years of trouble-free service with reasonable
care. However, if factory repair is needed, first contact a Campbell Scientific
application engineer to obtain an RMA (Return Materials Authorization)
number. An RMA number and product-safety documents are required prior to
any repair shipments being accepted at Campbell Scientific. See the
Assistance statement at the beginning of this manual for more information.
