3.6.2.2 General fault reset (Pn.15)
Functional description „Pn.15 > 0“
a) Thersterrorisresetafter a waiting period of approx. 4 seconds.
b) Any further errors that occur within the next hour, will also be reset at the end of the waiting period.
If there are more errors than adjusted in Pn.15 within this hour, the unit can only be reset manually via terminal
strip or via „BUS“.
Manual resetting of a fault resets also the „time grid“. That means, the next error will automatically reset again
after the waiting period.
