– Multi-Machine Sequencing
The Leader of the network is determined by the capacity. The largest machine becomes the Leader and
all smaller machines act as Lag compressors. If multiple machines have the same capacity, the machine
with the lowest total hours will assume the role of Leader, which allows total hours across sequenced
machines to equalize. Finally if multiple machines on the sequencing network are of the same size, total
hours, and capacity, the machine with the lowest unit number will become the Leader. The controllers will
trade the Leader role periodically as determined by the settings described below.
Path
: Machine Configuration -> Multi-Machine Sequencing
Under the
Multi-Machine Sequencing
menu of the AirSmart G2 Controller, there are eight user-
configurable parameters that control sequencing behavior. A distributor level or higher password must be
entered to view and make changes to these settings. Some of these values must be identical across all
machines in the sequence while others are dependent on the size of the unit or the operator preference.
Capacity
– Units: Cubic Feet per Minute (CFM) – Default Value: Factory Set – Capacity is used to decide
which compressor will become the Leader in the sequence. Normally the largest compressor will be the
Leader unless multiple compressors of the same capacity are present in the network, in which the
compressors will use total hours to decide and trade Leader control.
Number of Units
– Default Value: 8 – This value should not be changed.
Unit Number
– The Unit Number is a number between one and eight that is assigned to each
compressor in the sequence. This value is used to identify compressors on the network. No two
compressors can share the same unit number.
