17. SETTING BURNOUT
Burnout is a function to provide a fail-safe condition for equipment and devices on site by providing max. or min. output
when input is abnormal, disconnection of a wire, for instance. Burnout includes upscale burnout ‘H’ operating toward stop-
ping heating (max. output) and downscale burnout ‘L’ operating toward maintaining heating (min. output) in detecting the
input disconnection. When the unit detects the burnout, it indicates ‘B.ERR’. The default is upscale burnout.
IMPORTANT
Do not change the burnout setting while ‘B.ERR’ is indicated.
