Installation guide

The nine LEDs visible through the slot on the H7206-B panel provide fault
indications for the power regulators and for certain other faults such as
overtemperature.
LEDs 2 through 6 are latching and therefore detect momentary faults.
These LEDs are reset to Off by cycling the key switch to Off then back to
Standby or Enable. These LEDs can also be reset by pressing and releasing
the reset switch located beneath the LED indicators.
If a LED does not turn off after one of these reset procedures, then you
have not corrected the problem that is causing the LED to light.
Table 6–1 lists the meaning of each of the indicators.
