STARTUP
If the analyzer is new and has not been installed, follow the procedures described in Installation and
Configuration of Program before mounting. Mounting and wiring procedures for new installations vary
with equipment options — see drawing section for instructions. If the analyzer has been previously
installed, all that is required is to attach the electrode to the analyzer and then to turn on the power.
The analyzer will go through its automatic startup procedure any time power to the analyzer was lost for
more than a few seconds. The startup procedure initializes the analyzer program, performs error
checking, and then proceeds to display the chlorine and operate the analyzer normally.
All program settings, calibration settings, and the analyzer will have remembered defaults, as the
memory is none volatile.
Analyzer Startup Tests
The startup procedure will begin by alternately flashing [tESt] and [——] and blinking the top LED
while performing the memory tests. The analyzer will then display in sequence the analyzer number, in
this case [8760CL], any software option numbers, and the program version number, eg.[2.10]. The
program then proceeds to the display test that will light each of the implemented display segments in
turn. At the same time each of the LEDs will be lighted. If the analyzer passes all the tests, then the
hardware is functioning properly and the analyzer will proceed to display total free chlorine.
If the analyzer displays +Err or -Err, this indicates that the input is off-scale. The error LED will be
lighted as long as any input is off-scale. An off-scale error can indicate that the electrode is not in
solution, is off-scale, or is not connected properly. If the error LED remains lighted, go to the error
display section (select [Err] from main menu) to see what errors the analyzer has detected.
Calibration Settings Retained
If the analyzer was calibrated previously then the analyzer will use the calibration settings from the last
successful calibration, otherwise default settings are used. Error and caution messages generated during
the last calibration will remain in effect. AquaMetrix recommends a full chemical calibration of
chlorine after initial startup. Refer to the Chlorine Calibration section.
Analyzer settings and parameters can be viewed and/or changed at any time. Refer to the menus on
pages 3 to 5; the areas shaded in dark gray indicate program settings.
