Reset / Manual Lockout; Timeout For Menu Operation - Siemens AZL2 Series Service Manual

Reset / manual lockout

The system can be manually locked by simultaneously pressing the ENTER (InFo) button and any other button on the AZL2.... This
function allows the user to stop the system from the operating level should an emergency occur. When making a reset, the following
actions are carried out:
Alarm relay and the fault display are off

the lockout position is cancelled

the unit performs a reset, then it switches to stand-by

If the unit is in the lockout position, a reset can be made by pressing the InFo button for 1...3 seconds. The function is available only
when the unit is in the lockout position. Longer or shorter pushes on the button do not produce a reset so that the system maintains the
lockout position.

Timeout for menu operation

The time for automatically leaving the parameter setting level can be adjusted between 10 and 120 minutes, using the parameter 127
(Timeout for menu operation). If, during that period of time, there is no operation via the AZL2..., the parameter setting level is quit and
the password level reset to Info / Service.
Caution! In addition, this timeout or interruption of communication between the LMV2.. and the AZL2... during the time the
curves are set leads to lockout!
