    Section 1 SUPERVISOR PROTOCOL SECTION 1.1 SUPERVISOR II PROTOCOL VER 3.0 This document describes features that are more technical in nature than the normal opera- tion of the machine, in particular sequencing and communication. The Supervisor II communications link is a RS-485 (two wire) serial line. The following three parameters must be set correctly to be able to communicate through this link.

    Section 1 SUPERVISOR PROTOCOL Supervisor will not start, stop, load or unload unless a message commands the action. If the sequence parameter is set to HOURS or COM ID# then the broadcast mode is enabled. In this mode the machines send the net status message periodically. Approximately once a second, all machines that are on line will send a net status message.

    Section 1 SUPERVISOR PROTOCOL TIME SLICING OF THE RS-485 SERIAL CHANNEL When the sequencing mode is set to HOURS or COM ID# the machines will broadcast their status (net status message) about once a second. To keep machines from sending mes- sages simultaneously, time is sliced into periods (up to 9 maximum), one for each machine and one for a monitor.

Machine 2 immediately sends it’s net sta- tus message establishing the slot at 3. Since machine 3 is off line no message will be sent and after .125 sec.

    Section 2 SUPERVISOR II SEQUENCING Modes of Sequencing REMOTE - Enables three digital inputs for Remote Start/Stop, Unload/Load and Master Control. These inputs are normally controlled by remote relay contacts or a PLC controller. A customer may then interface with custom sequencing panels which provide signals for a 2-wire stop/start operation.

    Section 2 SUPERVISOR II SEQUENCING others will be forced to "FULL LOAD". The modulating (trim) machine will load at 2psig (.14 bar) above the load pressure parameter, 102 psig (7.03 bar) in this example, and unload at 2 psig (.14 bar) below unload pressure parameter, 108 psig (7.4 bar) in this example. The reason for this narrower load/unload band is to keep all machines from loading and unload- ing at the same time.

  • Page 18: Changing Sequence Parameters

    Section 2 SUPERVISOR II SEQUENCING Decisions to load, unload or start another machine are deferred until the timer reaches the RECOVER time setpoint. Note that the timer starts when a machine is added or taken away from the system. If the pressure recovers within the RECOVER time, and then at a later time the pressure drops below the Trim Low setpoint, another machine will load immediately.

  • Page 23: Philosophy Of Sequencing

    SUPERVISOR CONTROLLER SEQUENCING Philosophy of Sequencing All Sullair sequencing methods except base-load sequencing and sequencing with a VSD trim machine work under the same assumption. The most efficient use of compressors is either fully loaded or not running at all. Therefore, any time more than one machine is run- ning, all but the last one started is forced to operate at full load.

    Section 3 SUPERVISOR CONTROLLER SEQUENCING As machines are started and loaded, there will be only one machine that is modulating, the others will be forced to "FULL LOAD". The modulating (trim) machine will load at 2psig (.14 bar) above the load pressure parameter, 102 psig (7.03 bar) in this example, and unload at 2 psig (.14 bar) below unload pressure parameter, 108 psig (7.4 bar) in this example.

Decisions to load, unload or start another machine are deferred until the timer reaches the RECOVER time setpoint. Note that the timer starts when a machine is added or taken away from the system.

  • Page 31: Variable Speed Drive Applications

    VARIABLE SPEED DRIVE APPLICATIONS The most efficient use of a VSD machine in sequencing is to make it always be the trim machine and always be running. This can be accomplished using the existing Sullair sequence logic and configuring the machines as follows: I.

  • Page 33 Section 5 SEQUENCING TIMERS Recovery Timer & Delayed Start Timer The Recovery Timer is used to keep machines from starting, loading or unloading all at the same time. The Delayed Start timer is used to keep machines from starting unnecessarily due to temporary load changes.
  • Page 34 Section 5 SEQUENCING TIMERS The following examples show how the Recovery and Delayed Start timers work. Example 1: Recovery Timer - Unload Operation Example Suppose there are three machines running and loaded, the recovery timer is set to 10 sec- onds and the unload pressure is set at 110 on all three machines.
  • Page 35 Section 5 SEQUENCING TIMERS Example 2: Recovery Timer - Load Operation Example Suppose there are three machines running and with two unloaded and one in trim, the recovery timer is set to 10 seconds and the load pressure is set at 100 on all three machines.
  • Page 36 Section 5 SEQUENCING TIMERS Example 3: Recovery Timer - 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.
  • Page 37 Section 5 SEQUENCING TIMERS Example 4: Delay Start Timer - Pressure below Sequencing Load pressure but above Lowest Pressure 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.
  • Page 38 Section 5 SEQUENCING TIMERS Summary : Unload pressure - All machines unload above this pressure regardless of Recovery timer. 108-110 Recovery timer active - Trim machine will unload after Recovery timer expires. Sequencing unload pressure - Trim machine unloads above this pressure, Recovery timer starts. Sequencing load pressure - Next machine in sequence loads below this pressure, Recovery timer starts.
