NOTE: See RTU-MP 3rd Party Integration Guide (or alternatively RTU-MP 3rd Party Integration Guide (or alternatively RTU-MP Controls, Start-Up, Operation, and Troubleshooting Instructions (Form 48-50H-T-2T), Appendix) for Modbus Protocol Conformance Statement.

N2

1.Verify that the BAS and controller are both set to speak the N2 protocol. The protocol of the controller is set via SW3 (switches 3, 4, 5, and 6). The protocol can also be verified by getting a Modstat of the controller through the BACview. Hit the “FN” key and the ’.’ key at the same time to pull up a Modstat. Scroll to the bottom of the page and there is a section entitled ”Network Communications.” The active protocol and baud rate will be shown in this section.

2.Verify that the BAS and controller are set for 9600 baud. The baud rate of the controller is set via SW3 (switches 1 and 2). The baud rate can also be verified via the BACview by obtaining a Modstat. (See Fig. 59.)

3.Verify that the BAS is configured to speak 2-wire EIA-485 to the controller. The BAS may have to configure jumper or DIP switches on their end.

4.Verify that the BAS and the controller have the same communication settings (8 data bits, No Parity, and 1 stop bit).

5.Verify that the controller has a unique N2 slave address on the N2 bus. The controller’s N2 slave address is set by its rotary address switches.

6.Verify proper wiring between the BAS and the controller.

7.Verify that the BAS is reading or writing to the proper network point addresses on the controller. Download the latest points list for the controller to verify.

8.Verify that the BAS is sending his requests to the proper slave address of our controller.

NOTE: See RTU-MP 3rd Party Integration Guide (or alternatively RTU-MP 3rd Party Integration Guide (or alternatively RTU-MP Controls, Start-Up, Operation, and Troubleshooting Instructions (Form 48-50H-T-2T) Appendix) for N2 Protocol Conformance Statement.

ECONOMI$ER SYSTEMS

The 580J units may be equipped with a factory-installed or accessory (field-installed) economizer system. Two types are available: with a logic control system (EconoMi$er IV) and without a control system (EconoMi$er2, for use with external control systems). See Fig. 60 and Fig. 61 for component locations on each type. See Fig. 62 and Fig. 63 for economizer section wiring diagrams.

Both EconoMi$ers use direct-drive damper actuators.
