that the machine is running increments this counter.
When then ‘Sequence By’ parameter is set to
‘Hours’, the machine with the least amount of Seq
Hrs is started first, and the machine with the most
Seq Hrs is shut off first.
Com Number— Communications number. When two
or more machines are connected together using the
network (RS-485 channel), each machine must have
a unique number or address. These must be
assigned in numerical order. For example in a three
machine system the machine communications
numbers should be 1, 2 & 3.
Machines —This is the total number of machines
connected to the network (RS-485 channel). For
example in a three machine system, this parameter
should be set to 3. Up to sixteen machines may be
networked if all have Supervisor Controllers and
limited to eight if some have Supervisor II’s.
Low Press —This is the lowest pressure allowed
before immediately starting a machine. Recovery
Time—This parameter keeps multiple machines from
loading, unloading and starting at the same time. For
example if a low pressure condition causes a
machine to start, the next machine will not start
unless the Recovery Time has elapsed, and the
pressure has not recovered (i.e., has risen over ‘Low
Press’).
Rotate —This parameter is used only in very special
cases.
The only time this parameter should be used is in a
situation where, once a machine is started, it never
stops (ie. the unload timer never expires). This can
happen when the load matches the output of the
machine, all the time. In this case the machine will
never unload and shut off. The rotate forces the
machine to stop after it’s Seq Hrs. are greater that
the other machines. For example in a two machine
system, with Rotate set at 100 hrs. The machine that
is running will shut off when the Seq Hrs. are 100
more that the machine that is stopped.
Minute, Hour, Day, Month, Year —For Controllers
manufactured after April 2009 or if the
Communications Module is present in the system,
the time and date can be set using these parameters.
2.10 SYSTEM DISPLAY—DISPLAY
OF MODES OF MACHINES IN
A SEQUENCING SYSTEM
Note that this display is only applicable when there
are two or more machines connected to the
communications network (RS-485) and the
Sequence By parameters on each machine are set to
‘Hours’ or ‘Number’.
The columns are described below
Communication Number Status —
E —Emergency Stop
M —Manual stop
R —Remote stop
B —Standby
S —Starting
U —Unloaded
L —Loaded
T —Trim machine
F —Full load
Sequencing Hours
Capacity —Not used at this time.
Local System Pressure —Pressure read by
machines pressure transducer.
The top line is a legend that describes each column.
The right hand number on the top line is the system
pressure. The system pressure is the highest
pressure reading of all the machines. Note that the
local pressure readings can be used to determine
what machines may need to be calibrated. The
system pressure transducers on all machines should
read within 1(one) psi of one another. The calibration
function can be used to set the readings to be the
same.
2.11 CALIBRATION—
CORRECTION FACTORS
FOR PRESSURES
The first line of this display is the password. If the
password is 0 then the following parameters are not
protected and can be changed. If the password is
non-zero, then enter the displayed number plus 4 to
enable changing the parameters. For example if the
number displayed is 10 then changing the password
to 14 will enable editing.
NOTE
Leave this parameter disabled unless
instructed by Sullair Service Personnel.
