Operating Mode
• Mains Parallel or No Parallel
• Mains Parallel will allow the unit to synchronize to the mains, and carry load
while in parallel with the mains as well (closed transition).
• No Parallel will not allow the unit to operate with load until the mains
breaker is sensed as being open (open transition).
• All units operating in a load sharing system must be set for the same
parameter (that is, mains parallel, or no parallel).
Number of Units (single, multiple)
• Defines whether unit is part of a multiple unit system or not.
• If single unit, there is no auto starting, auto sequencing, load or PF sharing
with other units under any circumstances. Unit displays “single unit no
sequencing” on sequencing screen. Network Priority and Network Address
setpoints are removed from the configuration setpoint menu automatically.
• If multiple unit, auto starting, auto sequencing, load and VAR/PF sharing
are available between all units in multiple. Unit displays system sequencing
information on sequencing screen. Network Priority and Network Address
setpoints are added to the configuration setpoint menu automatically. Unit
must be in Auto mode to communicate over the inter-control network (RS-
485).
