The Mixing Control 360 has a built-in test routine which is used to test
the main control functions. The 360 continually monitors the sensors,
and displays an error message whenever a fault is found. See the fol-
lowing pages for a list of the 360’s error messages and possible causes.
When the Test button is pressed, the test light is turned on. The indi-
vidual 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 may be paused by pressing the Test button. Only if there is a mixing demand can the
control be paused in a step. 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.
