AUTO DUAL TIMER SETUP
TIMED STOP DELAY IN MINUTES ➔ ______
***************************************
PRESS ENTER TO ACCEPT VALUE
This is the time that the compressor will run in an
unloaded state prior to shutting down. The
compressor will then be in standby mode, and will
restart when the system demand requires it.
************ MACHINE ID SETUP************
MACHINE ID FOR THIS COMPRESSOR ➔ ____
******************************************
PRESS ENTER TO ACCEPT VALUE
In order for compressors on a network to
communicate properly, each machine must be
assigned an individual identifier. Power$ync II
™
uses letters, A through F, to identify individual
compressors on the network. Each machine on
the network must be assigned a different letter.
Use the UP or DOWN arrow keys to scroll through
the alphabet until the desired letter is reached.
When the letter desired is reached, press ENTER
to accept.
If the letter selected is currently being used by another
compressor on the network, the following message will
be displayed:
NOTICE
THIS COMPRESSOR MACHINE ID
IS ALREADY IN USE
PRESS ENTER TO CONTINUE
If this message is displayed, press ENTER to return
to the Machine ID selection display so a new letter
can be selected.
If the selected machine ID is not in use by another
compressor on the network, pressing ENTER will be
followed by this display:
PLEASE WAIT
NETWORK CONFIGURATION IN PROGRESS
This message will be briefly displayed as the
controller communicates its ID and operational
capabilities to the other compressors on the
network. The display will then automatically
return to the Network Configuration Menu 1.
Press the UP key at Network Configuration Menu 1 to
move the controller to Network Configuration Menu 2.
This menu is used to set sequences and schedules for
multiple machine operation.
NETWORK CONFIGURATION MENU 2
SET SEQUENCE ➔ PRESS F1
SET SCHEDULE ➔ PRESS F2
UP FOR NEXT MENU/DOWN FOR PREVIOUS MENU
Press F1 to access the Network Sequence Setup
display. A sequence is defined as the order in
which compressors will respond to changes in
system demand. Power$ync II
™
allows the
operator to set up to nine different sequences.
NOTE
Schedule and sequence information can be set
from any machine on the network. The network,
however, looks to the machine ID closest to ‘A’
for automatic updating of the network. This
automatic updating occurs every 17 minutes. If
schedule and sequence changes are being made
from a machine other than the ‘A’ machine at
the time that the network automatically updates,
the new information may be erased and old
schedule and sequence data used in its place. It is
advisable to make all changes to the schedules and
sequences from the ‘A’ machine. If that is not
practical, ALWAYS review the changes made
before transferring them to the other machines
on the network and then reconfirm the changes
after they have been transferred.
