Section 4 Parameters
Parameters Introduction 4-1
The Siemens LMV5 BMS has a number of parameters (settings) that can be adjusted to suit the
wide variety of applications that exist in the burner / boiler and industrial heating market.
These parameters are broken up into three main groups by password access.
User Level access does not require a password, and encompasses all of the parameters that
an end user might have to look at and / or adjust during the life of the burner / boiler.
Service Level access does require a password, and this level encompasses all of the user level,
plus parameters that a service technician might need to access, to tune or maintain the
burner / boiler.
OEM Level access requires a different password than the service level, and enables the OEM
to access all parameters, including safety related parameters.
The parameters are accessed through the AZL5 in an outline-type structure that will be thoroughly
illustrated on the following pages.
Notes:
1) Fault history and lockout history are ONLY stored in the AZL, and NOT in the LMV5.
2) These histories retain the last 9 lockouts and the last 21 faults, from whatever LMV5
they were on at the time, and cannot be purged.
3) These histories will remain in the AZL even when power is removed, or the AZL is
moved to another LMV5.
4) Passwords are stored in the LMV5, and are part of a parameter set.
5) Any/all parameter changes made, are always done in the LMV5.
6) A Backup LMV5 > AZL makes a backup copy of a parameter set,
from the LMV5 to the AZL.
7) A Backup AZL > LMV5 (technically a Restore) replaces a parameter set,
from the AZL to the LMV5.
8) Backups and restore procedures are covered in more detail later in this section.
