Testing the Control
The Mixing Control 362 has a built in test routine which is used to test the main control
functions. The 362 continually monitors the sensors and displays an error message whenever
a fault is found. See the following pages for a list of the 362’s error messages and possible
causes. When the
test button is pressed, the test light is turned on. The individual outputs and
relays are tested in the following test sequence.
TEST SEQUENCE
Each step in the test sequence lasts 10 seconds.
During the test routine, the test sequence is paused by pressing the
Test button. While paused, the control displays the testing step as
well as the word PAUS. If the
Test button is not pressed again for 5 minutes while the test sequence is paused, the control exits the entire
test routine. If the test sequence is paused, the
Test button can be pressed again to advance to the next step. This can also be used
to rapidly advance through the test sequence. To reach the desired step, repeatedly press and release the
Test button until the
appropriate device and segment in the display turn on.
