NetSure™ LMS Data Processing Unit
Installation Instructions, Section 5879 (Issue BA, April 7, 2014)
Spec. No: 58650500, 586505500 Code: Section 5879
Model No: LMS1000 Issue BA, April 7, 2014

Sequential Start Connections
Note: The LMS1000 Energy Management and Sequencing features
are not for use in Spec. Nos. 582140000, 582140001, or
582126100 Power Systems.
Note: Requires the Sequential Start software option.
LMS1000 requires dedicated binary and relay ('traditional rectifiers
only) inputs/outputs which are connected as described below.
Refer also to Figure 22.
VPS/NPS Power System's PCUS and External 'Traditional'
Rectifiers
• To use the standby sequence and/or commercial AC
sequence option, you must connect a dedicated binary
input to a commercial AC fail or transfer circuit.
• For standby sequencing, an additional binary input must
be connected to a standby on or proper operate signal.
External 'Traditional' Rectifiers Only
• Binary inputs connected to each rectifier’s RFA alarm
output. If the rectifiers were connected to binary inputs
for energy management (as described in the previous
procedure), these binary inputs are also used for
sequential start and no additional binary input
connections are required.
• Relay outputs connected to each rectifier and wired to
turn the respective rectifier ON or OFF through its TR
(RCC) leads. If the rectifiers were connected to relay
outputs for energy management (as described in the
previous procedure), these relays are also used for
sequential start and no additional relay output
connections are required.
Note: Only wire to relay circuit cards installed in the
586505000/586505500 Main Cabinet. DO NOT use
relay circuit cards installed in
586505000/586505500 Expansion Cabinets for
controlling rectifiers.
Note: Relay outputs configured for programmable event
control cannot be used to control a rectifier.
