19�5�2 Controller self-oscillating
P-area too small or amplication too great. Increase the P-area or reduce the amplication until the
self-oscillation stops.
19�5�3 The controller error on the controller settings page is less than the dierence between
the actual value and the set value
This is not actually an error. The controller error on the settings page should never be more than half
the dened P-area. If this happens regularly, the P-area may be too small, causing the controller to
self-oscillate. Increase the P-area.
