Adjusting Sequence Parameters - Sullair WSPC User Interface Manual

WSPC USER INTERFACE
Drain Interval (seconds) – Set this time as the desired interval between
activation of the drain cycle for machines equipped with an electric solenoid
drain. This value is displayed in units of minutes at the WS Controller.
Drain Time (seconds) – Set this time as the number of seconds that the drain is
to remain energized.
Restart Time (seconds) – Set this time to the desired number of seconds before
auto restart is to occur on power up. Set it to zero (0) to disable auto restart.
Wye-Delta Time (seconds) – Set this as the time for the wye to delta starter
transition. This can also be used to control the closed inlet valve with other
motor controls.
Cost per KWH – Available only with VSD equipped machines. Sets the KWH
cost value, in dollars or other currency, used in operating cost calculations.
Modulation – Assigns the manner in which the machine will be delivering air
(Load/Unload or Modulate).
Mode – Assigns the desired mode for controlling the compressor motor operation
(Automatic or Manual).

3.8.3 Adjusting Sequence Parameters

This group of adjustments set the controller for operation with other Sullair
compressors or for remote control. Refer to the WS Controller Sequencing and
Protocol Manual for the principles of operating compressors in sequence.
Section 3.6
Display which allows the user to monitor the operation of all the compressors
connected in sequence.
To configure a machine for sequencing operation:
1. Click in the "Sequence Mode" field to select the mode by which
sequencing of the compressor is to be controlled. See Figure 3.13.

Select "Disabled" when no sequencing is desired. The machine
will not operate in sequence with other machines. The compressor
can still be operated as a stand alone machine.
