AK-LM 330
The controller can only be configured when
it is unlocked.
It can only be adjusted when it is locked.
Changes to the input and output settings
are only enabled when the controller is
"Locked"
The values can be changed when it is locked,
but only for those settings that do not affect
the configuration.
In general
Many settings are dependent on previous set-
tings. This is shown by the fact that a function
can only be seen (and thus set) if an earlier
parent function allows access to this subordi-
nate function
For example, the "Configuration lock" line will not
be shown if the main switch is set to On. Only
when the main switch is set to Off, and regulation
has therefore been stopped, is it possible to set
the configuration lock.

Main Switch
Used to start and stop regulation.
When the main switch is set to Off, all outputs
are in standby mode and all alarms are
cancelled.
The main switch must be set to Off before the
Configuration lock can be Unlocked.
Configuration lock
The controller can only be fully configured
when the configuration lock is set to Un-
locked.
The settings are only applied when it is set
to Locked again. At this point, the controller
checks the functions set and compares them
with the input and output settings.
Important settings can then no longer be
changed unless the configuration is unlocked
again.
