Overview
Compressor sequencing in the MicroVission panel is car-
ried out by utilizing the Ethernet communication port
using TCP protocol.
Compressor sequencing is accomplished by every com-
pressor, monitoring its own control parameter (either
suction pressure, process temperature). As its control
parameter changes value, it will make decisions based
on the own priority and status of other compressors con-
gured in sequencing to start, stop, load and unload the
compressor as needed, to maintain the control setpoint
which is dened in the compressor sequencing screen.
The following discussion assumes that the physi-
cal Ethernet Network has been installed between all
MicroVission control panels.
Conguration Overview
Setup of Compressor for Sequencing
Logon to the Compressor and navigate to the
Compressor Sequencing screen, page 1. Compressors
can be setup for sequencing from Equipment List.
Options under Equipment List are populated depending
on devices shown in Device List Screen of Compressor
Sequencing Menu.
