Table 6.1: Setting MODE switches S3 and S4
When setting the gain characteristic curve, you must ensure that MODE
switches S3 and S4 are always identically set. If there are any differences
between the MODE switches, the red "Switch Error" LED illuminates and an
error shutdown of the flame monitor occurs after 8s.
To avoid an error shutdown, MODE switches S3 and S4 must be set to the
same position within 8s.
