Section 5
SEQUENCING TIMERS FOR
EFFICIENT OPERATION
23
2 Trim
3 Unloaded (Next machine in sequence)
The next machine in sequence will wait for 10 seconds before loading if the pressure
stays at 101 or 100. If the pressure goes above 101 loading will be unnecessary. If the
pressure goes below 100 the machine will load immediately (regardless of the recovery
timer).
5.2.3 EXAMPLE 3– STARTING EXAMPLE
Pressure drops below lowest pressure setting:
Machines will start when the system pressure drops below the Lowest Pressure setting,
or when system pressure drops below the load setting for a period of time determined by
the Delayed Start timer. The following example shows operation when the pressure
drops below the Lowest Pressure setting. A later example will show how the Delayed
Start timer works (i.e. the pressure is below the Load setting but above the Lowest
Pressure setting).
Configuration: Three machines running with one in trim and two are stopped
The Lowest Pressure setting is 70 psi.
Machine Status
1 Trim
2 Stopped (Next machine in sequence)
3 Stopped
If the system pressure drops below the lowest pressure setting (70) the next machine in
sequence (2) will start and trim, the previously trimming machine (1) will go to full load.
Machine Status
1 Full Load
2 Trim
3 Stopped (Next machine in sequence)
The next machine in sequence will wait for 10 seconds before starting if the pressure
stays below 70. If the pressure goes above 70 the machine will start after the Delayed
Start timer expires (explained later).
5.2.4 EXAMPLE 4– STARTING EXAMPLE
Pressure between lowest and load pressure setting:
The Delayed Start timer comes into play only when the system pressure is below the
Sequencing Load pressure setting but still above the Lowest Pressure setting. This timer
value is prorated between the Sequence Load pressure and Lowest Pressure.
Example, the Load Pressure is 100 and the Lowest Pressure is 70.
If System Pressure is above 101 and drops to (and stays at):
99, the machine will start in about 2 minutes.
85, the machine will start in about 1 minute.
70, the machine will start in about 30 seconds.
Configuration: Three machines running with one in trim and two are stopped
The Lowest Pressure setting is 70 psi.
