c. WA400 Manual
d. 115 V AC-to-12 VDC Transformer (-AC, -BU and –AL models only)
II. Inspection
a. Your WA400 unit was carefully inspected and certified by our Quality
Assurance Team before shipping. If any damage has occurred during
shipping, please notify Global Water Instrumentation, Inc. and file a
claim with the carrier involved.
Use the checklist to ensure that you have received everything needed
to operate the WA400.
III. Operation
The High Water Level Alarm will sound a loud speaker and flash a bright
red strobe when a switch closure signal is detected. This signal is usually
from a water level sensor, but can be integrated with other equipment
such as our PC300 controller or any device that has a dry contact switch
output. The WA400 also has the ability to output a switch closure signal to
control an external device simultaneously such as samplers, pump panels,
and security switches.
