format which can easily be imported into a spreadsheet for record keeping or
presentation purposes. The user is responsible for translating power consumption
data into dollars billed.
To use this feature, an analog channel must monitor system voltage and other analog channels
must monitor load current for each equipment to be monitored for power consumption. A
function channel must be configured for each equipment to be monitored for power
consumption by entering the phrase "KW" for the "Unit Text", and entering the appropriate
program line to multiply the value of the analog channel monitoring system voltage with the
value of the analog channel monitoring load current, then divide this product by 1000 [i.e.
F01=(A0001*A0002)/1000]. Instead of dividing by 1000, you could multiply by 0.001 [i.e.
F01=A0001*A0002*0.001]
To get a report, enter the command POWER. Any time the POWER command is entered,
LMS1000 generates a power consumption report for the function channels and displays the
resulting information. For the "comma separated value" format, enter the command POWER
CSV. The POWER command is available to a user programmed for access to level 1
commands.
To clear the Power Metering data, enter the command CLR POWER. The CLR POWER
command is available to a user programmed for access to level 4 commands.
1.5.3 Energy Management Software Option (if installed): The optional energy management
programming permits an installation to only operate rectifiers/PCUs as needed to maintain the
load and keep batteries in a fully charged condition. As load increases, the energy
management feature will turn on additional rectifiers/PCUs as needed in 15 second intervals
when load requirements exceed a user selectable percent (90-99%) of the total capacity of the
operating rectifiers/PCUs to maintain the load. LMS1000 will also turn off rectifiers/PCUs as
necessary in 15 minute intervals if the load decreases below a separate user selectable
percent of the total capacity of the would be operating rectifiers/PCUs. Rectifiers/PCUs which
are always operating to maintain any load requirements are cycled through the group of
rectifiers/PCUs controlled by this feature to provide uniform operating times for each
rectifier/PCU. This rotation occurs from 1-365 days (at midnight), as selected by the user. The
base rectifier/PCU is rotated decrementally through the group. As an example, first
rectifier/PCU 5 was on at all times, at the programmed time interval rectifier/PCU 4 is on at all
times, and at the next occurrence of the programmed time interval rectifier/PCU 3 will be on at
all times. If energy management is used, all rectifiers/PCUs in the system should be
controlled.
Energy Management Channels: A maximum of 80 energy management channels can be
programmed, thus LMS1000 can support any combination of up to 80 energy managed
rectifiers and PCUs. An energy management channel combines two input channels with a
single output channel (rectifier only) per rectifier/PCU to accomplish the task of controlling the
rectifiers/PCUs for energy management and sequential start purposes.
Note: The number of rectifiers that can be controlled is limited to 32 due to the availability of
32 relay channels dedicated for energy management/sequential start. PCUs do not
require hard wired relay channels for energy management, hence 80 PCUs may be
controlled. Any combination of rectifiers and PCUs may be controlled, up to 80 total, as
long as rectifiers don't exceed 32.
Note: Operation of Energy Management is disabled when the Dual MCA Interface option is
installed.
1.5.4 Sequential Start Software Option (if installed): LMS1000 can support up to 80 sequential
start controlled rectifiers/PCUs (see note above). There are two types of optional sequencing
available with the sequential start option: commercial AC sequencing and standby
sequencing. Commercial AC sequencing permits sequential starting of rectifiers/PCUs
assigned to energy management channels when commercial AC input fails and subsequently
is restored. When AC power is lost and then resumes, the AC sequencing option turns off all
controlled rectifiers/PCUs, and then starts the rectifiers/PCUs sequentially at 15 second
