Section 5
SEQUENCING TIMERS FOR
EFFICIENT OPERATION
22
85, the machine will start in about 60 seconds
70, the machine will start in about 30 seconds
Because of varying pressures and other delays these times are approximate.
5.2 TIMER OPERATION EXAMPLES
The following examples show how the Recovery and Delayed Start timers function.
5.2.1 EXAMPLE 1– UNLOAD OPERATION
Configuration: Three machines running and loaded
The recovery timer set to 10 seconds
The unload pressure is set at 110 on all three machines.
The sequence unload pressure will be 108 psi
Machine Status
1 Full Load
2 Full Load
3 Trim
If the pressure rises above the sequence unload pressure (108) the trim machine will
unload and the next machine in sequence will trim.
Machine Status
1 Full Load
2 Trim
3 Unloaded
The new trim machine will wait for 10 seconds before unloading if the pressure stays at
109 or 110. If the pressure goes below 109 unloading will be unnecessary. If the
pressure goes above 110 the machine will unload immediately (regardless of the
recovery timer).
5.2.2 EXAMPLE 2– LOAD OPERATION
Suppose there are three machines running and, the recovery timer is set to 10 seconds
and the load pressure is set at 100 on all three machines.
Configuration: Three machines running with two unloaded and one in trim
The recovery timer set to 10 seconds
The unload pressure is set at 100 on all three machines.
The sequencing load pressure will be 102.
Machine Status
1 Trim
2 Unloaded (Next machine in sequence)
3 Unloaded
If the pressure drops below the sequence load pressure (102) the next machine in
sequence (2) will load and be the trim machine, and the previously trimming machine (1)
will go to full load.
Machine Status
1 Full Load
