    Supervisor and Supervisor II Deluxe controllers all feature internal sequencing functions. Supervisor requires a communications module for these features. These operate as a dis- tributed control system (rather than a master-slave relationship), so the system remains operational even if a member is taken off-line. Refer to Section 2 for details.
  • Page 8 Section 1 SAFETY AND INTRODUCTION Section 4 covers application of controllers in master-controlled systems. Timers used in internal sequencing are described in Section 5. Section 6 contains technical details of the hardware and protocol used on the communica- tion bus. Other equipment may monitor this for data and presentation of system perform- ance.

    Section 2 SEQUENCING WITH MULTIPLE SUPERVISOR CONTROLS 2.1 NORMAL OPERATION Supervisor and Supervisor II Deluxe controllers all feature internal sequencing functions. To enable any Supervisor in the system, press the Auto key and Remote key on the key- pad. Enable the Supervisor II Deluxe by simply pressing the Auto button.

    The fixed-speed machine(s) must be set up for load/unload operation. If controlled with Supervisor II Deluxe controllers, the pressure regulator/s must be made to have no effect by operating the system below their effective range. If controlled by the Supervisor Controller, the controls may be programmed for Load/No load operation whereby the Full Load valve is energized any time the machine is running, thus defeating modulation.

The system will normally cruise at 98-100 psi. 3.3 SETUP FOR MULTIPLE VSD COMPRESSORS With pressure-controlled VSD circuits, configure all compressors by Sequence Hours or Com Number, as desired. Enable the Max. Speed Input function. All but one of the com- pressors will be full-loaded, thus limiting the pressure to the rated value of the machines.

    Local/Master Output K8 D5, D6 and D7 are wired through customer furnished relay contacts to ground (Supervisor Signal GND). If D5 is open the machine will stop, and be held stopped. If D5 is grounded, the machine will be enabled to start; the following table describes how the other inputs work:...

    Inputs D8, D9 and D10 are wired through customer furnished relay contacts to ground (Supervisor II Deluxe Common J3-20). If D10 is open the machine will stop, and be held stopped. If D10 is grounded the machine will be enabled to start. If remote start/stop is not needed then jumper D10 (J3-19) to GND (J3-20).

    Section 5 SEQUENCING TIMERS 5.1 RECOVERY TIME AND 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.

    Section 5 SEQUENCING TIMERS 5.1.3 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.
  • Page 24 Section 5 SEQUENCING TIMERS Stopped If the system pressure drops below the Sequence Load pressure (102) but is above the Lowest Pressure (70), the next machine in sequence (2) will start and trim, and the previ- ously trimming machine (1) will go to full load after the Delay Start timer expires. If the pres- sure is at 85 then the machine will start in about 1 minute (see previous table).

    Section 5 SEQUENCING TIMERS 5.2 SUMMARY Unload pressure - All machines unload above this pressure regardless of Recovery timer. Recovery timer active - 108-110 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.

    This information may be used for the design of monitoring systems of controllers. Communications connections are included with all Supervisor II Deluxe controllers. A communications module is added to standard Supervisor controllers for any external communications. Most features are com- mon to either controller, unless specifically noted below.

    Section 6 SUPERVISOR PROTOCOL nected or disconnected at any time. 6.3 RS-485 SERIAL CHANNEL The half-duplex RS-485 is a party line type channel, ie. any device on the channel may transmit or receive on the same wires. The transmitters and receivers are differential type that use two wires and a ground.
  • Page 29 Section 6 SUPERVISOR PROTOCOL machine assigned to that time slot is off line and the next time slot starts. A machine sends a net status message immediately after a message is received from the next previous machine, or that machine’s time slot has expired. For example if the time slot has been established as 2 and either machine 2 sends a net status message or no mes- sage is sent within .125 seconds, then machine 3 will send a net status message (if on line).
