stops energy management and turns on all
rectifiers/PCUs.
Note:
The alarm limits for A9001 are the settings of the
VPS/NPS Power System's battery on discharge alarm,
50% battery on discharge alarm, high voltage alarm
1, and high voltage alarm 2.
Note:
The alarm limits for A9901 are the settings of Spec.
Nos. 582140000, 582140001, and 582126100
Power System's battery on discharge alarm, voltage
is very low, high voltage alarm 1, and high voltage
alarm 2.
c. A failure of any associated analog circuit card or failure of
the CPU circuit card stops energy management and turns
on all rectifiers/PCUs.
d. Loss of communications to the VPS/NPS Power System
stops Energy Management and turns on all controlled
rectifiers/PCUs.
PROCEDURE:
The energy management feature, if provided, can be activated or
disabled by using the command SET EFF which is described below.
This command displays a header that contains the current
configuration information. Then, individually, the command will
list each item that can be changed, prompting for new or revised
information to be entered. If the current information does not
need to be changed, press
ENTER
to continue. This command is
available to users programmed for access to level 6 commands. A
user with access to level 5 commands is allowed to enable or
disable the operation of the energy management feature using
this command.
1. After logging onto the system, type
SET EFF.
Then press
ENTER
.
Command <6>: SET EFF
2. The system displays the default (or current) configuration
of the energy management option, followed by...
Plant Voltage Input= A
3. Type the number of the analog channel connected to a
plant input voltage source, then press
ENTER
. If the
analog channel displayed is correct, press the
ENTER
key
to end this command.
Note:
If used with a VPS/NPS Power System, you may enter
A9001 here.
Note:
If used with a Spec. No. 582140000, 582140001, or
582126100 Power System, you may enter A9901
here.
4. The system responds with...
Enter Base Rectifier Cycle Period (1-365
days):
5. Type the number of days the base rectifier/PCU is to
remain on before the next controlled rectifier/PCU (in a
decremental rotation) becomes the base rectifier/PCU.
6. The system responds with...
Percent of system capacity at which to
turn off a rectifier (0.90-0.99):
Note:
The value of percent capacity at which to TURN ON a
rectifier/PCU must be GREATER THAN or EQUAL TO
the value of percent capacity at which to TURN OFF a
rectifier/PCU.
7. Type a decimal number from .9 to .99 which represents
the percent of total capacity of the would be operating
rectifiers/PCUs. When load decreases to this percent, a
rectifier/PCU is turned off.
8. The system responds with...
Percent of system capacity at which to
turn on a rectifier (0.97-0.99):
9. Type a decimal number from .97 to .99 which represents
the percent of total capacity of the operating
rectifiers/PCUs. When load increases to this percent, an
additional rectifier/PCU is turned on.
10. The system responds with...
Save changes (Y or N):
11. Type
Y
if the above entered data is to be saved in the
configuration and
N
if not, then press
ENTER
.
12. The system responds with...
RECTIFIER EFFICIENCY (Y or N):
Note:
A user with access to level 5 commands can execute
this part of the command only.
13. Type
Y
if it is desired to have energy management active.
Type
N
if it is desired to have energy management
disabled. Then press
ENTER
.
Setting Sequential Start (if Sequential Start Software Option
Installed)
Note:
The LMS1000 Energy Management and Sequencing features
are not for use in Spec. Nos. 582140000, 582140001, or
582126100 Power Systems.
This procedure shows the user how to enable or disable the
standby and/or AC sequence option, if provided. This procedure
also enters into the system the numbers of the binary channels
required for sequence operation. A time delay can also be entered
which will delay rectifier/PCU sequential start to allow the standby
