6.2 Power failure
In case of a power failure, the constant climate chamber operates as follows:
In normal and week time switch operating modes
After the power supply has been restored, operation is continued with the parameters set. The
time and the duration of the power failure is documented in the log memory (see page 52 ).
In programming mode
► After a power failure of less than 60 minutes, the current programme is continued from
the point at which it was interrupted. The time and the duration of the power failure is
documented in the log memory (see page 52 ).
► For a power failure of more than 60 minutes, the constant climate chamber starts in
manual operating mode for safety reasons and all setpoint values are changed to safe
default values (see table below).
For remote (computer) operation
If there is a power failure in remote operation, the constant climate chamber starts in manual
operating mode for safety reasons and all setpoint values are changed to safe default values
(see table). The programme can only be continued from the computer. The time and the dura-
tion of the power failure is documented in the log memory (see page 52 ).
