If an I/O board on your COPELAND E2 is not getting power, you should check the I/O board power. First, see if the green STATUS light is on. If it is not, check the power wiring connections and use a multimeter to verify that the board is getting 24VAC. If necessary, reset the power to the board.

If an I/O board on your COPELAND E2 is not communicating, you should check the I/O network connections.

1. Check the wire polarity to ensure it is positive to positive and negative to negative.

2. Check for any broken or loose wires.

If the dip switches on your COPELAND E2’s I/O board are set incorrectly, you need to check the I/O board network dip switches. Verify that the network ID number is not a duplicate and that the baud rate switches are set to 9600. If the switches are wrong, make the necessary changes and then reset the controller.

For the I/O network on a COPELAND E2, you must check for the proper setting of terminating resistance jumpers. The network segment should be terminated on the two endpoints of the daisy chain and should be unterminated everywhere else.

If the boards on your COPELAND E2 network are not powered, you should check the Network/Power voltages.

To troubleshoot faulty wiring on the Echelon Network for your COPELAND E2, check the connections. Look for any wires that are broken or loose. Also, check the network polarity to ensure it is positive to positive and negative to negative. Finally, check for any wire damage.

If the termination jumpers are set incorrectly on the Echelon Network of your COPELAND E2, you need to check for the proper setting. The network segment should be terminated on the two endpoints of the daisy chain and should be unterminated everywhere else.

For the Echelon Network on a COPELAND E2, each controller must have its own subnet address. If the subnet is set incorrectly, it can cause problems.

If your compressor will not operate with the COPELAND E2, there are several possible causes and solutions:

• Compressor not programmed properly: Verify that the E2 was programmed for the correct number of compressor stages. Highlight the General tab (C1) in the Suction Group Setup screen and check if the “Number of Stages” field is correct.

• Compressor types set up incorrectly: Make sure that compressor stages were properly set up as VS (variable speed), C (compressor), or U (unloader).

• Compressor programmed with incorrect rating: Verify that compressors were assigned the proper rating (HP/AMP, or BTU).

• Pressure setpoints set up incorrectly: Set the proper pressure setpoints. If controlling using suction pressure, enter the setpoint in the SUC PRES SETPT field. If controlling by temperature, enter it in the CTRL TEMP SETPT field. These setpoints are located under the Setpoints tab (C2) in the Suction Group Setup screen.

• Board and point addresses are incorrect: Set the proper board and point settings for input, output, and compressor outputs. These are located under the Inputs tab (C4), Outputs tab (C5), and Comp Outs tab (C7) in the Suction Group Setup screen.

• 8RO fail-safes are not wired correctly: Verify the fail-safe wiring on the 8RO board for N.O./N.C. positions. One wire should always be connected to the middle terminal, and the second wire to either the N.C. terminal (for relay ON during power failure) or the N.O. terminal (for relay OFF during power failure).

• Compressor in override: Highlight the compressor stage and cancel the override by pressing Enter to open the Actions Menu and selecting Override options. You can also go to the Override/Bypass Log from the Status menu to view and cancel overrides.

• Rack is in Phase Fail: Verify the correct phase and input for phase loss. The Phase Loss input is automatically configured to use the E2’s Global Data phase loss protection source. To define a different source, re-define this input definition by pressing F3 (EDIT) and then 1 to change the definition format.

• Oil sensors are set up but are not in use: Remove oil sensors from individual compressors. Highlight the Comp Setup tab (C6) in the Suction Group Setup screen, select the OIL SENSOR field, and choose “None” from the LOOK UP menu.

If you are having problems with the condenser on your COPELAND E2, refer to the following solutions:

• Condenser will not operate: Verify that the E2 is programmed with the proper number of fans. Highlight the General tab (C1) in the Condenser Setup screen and check the “Number of Fans” field.

• Incorrect board and point settings: Confirm proper board and point settings. Go to the Inputs tab (C3) in the Condenser Setup screen to check PRES CRTL IN and DISCH TRIP IN.

• Fail-Safe wiring on 8RO is incorrect: Verify proper fail-safe switch positions on the 8RO board. Set the rocker UP (ON) to close the relay and turn the output ON during a network failure. Set the switch DOWN (OFF) to open the relay and turn the output OFF during a network failure.

• Condenser will not split: Enable the condenser to split. Go to the General tab (C1) in the Condensers Setup screen and set the Split Enable field to “Yes.”

• Unsplit setpoint is set too low: This may be because the setpoint value is being compared with discharge pressure instead of temperature. Enter the value in terms of discharge pressure. Go to the Setpoints tab (C2) in the Condensers Setup screen and check that the UNSPLIT STPT field value has been entered as a pressure value.

• Half of the fans are not running: Check the split fan relay output. Go to the Other Outs tab (C7) in the Condensers Setup screen and check that SPLIT FAN has a board and point assignment. Also, verify that Split is enabled on the General tab (C1) and that the output is ON.

If you are experiencing issues with cases on your COPELAND E2, here are some troubleshooting steps:

• Case will not go into hot gas or cool gas defrost: Check the Group LLSV in the Suction Group setup. Go to the Outputs tab (C5) on the Suction Groups Setup screen and check GROUP LLSV. Also, verify that the case(s) is assigned to the correct group.

• Case will not terminate out of defrost mode: Verify the termination type (Term Type) in the Defrost tab (C4) of the Standard Circuits Setup screen. Check the defrost termination input location on the circuit input. Go to the Inputs tab (C6) and check DEFROST AV TERM.

If you are having problems with global actions and information cannot be read from another COPELAND E2 controller, you should verify that the controller with the sensor is set up as the Primary and the controller receiving the information is set up as the User. Both controllers default as local, so this may need to be changed.

If you are having problems with a temperature sensor or pressure transducer on your COPELAND E2, follow these steps:

• 16AI input dip switches are set improperly: The 16 dip switches on the 16AI board correspond to each input. Dip Switches Up = Temperature Sensor. Dip Switches Down = Pressure Transducer. Ensure they are set correctly.

• Incorrect board and point address: Set the proper board and point settings for both input and output. Go to the Inputs tab in the application’s Setup screen and check Board and Point.

• Incorrect sensor type:

  1. Verify that the sensor type in the E2 is the same as the sensor installed (e.g., “5V-200PSI” for a 5-volt powered 200PSI pressure transducer).

  2. From the Main Menu, select System Configuration (7) and Input Definitions (1).

  3. Highlight the desired input and press F1 (SETUP) to check Sensor Type.

If you have no heat or air, check the following on your COPELAND E2 system:

• Incorrect board and points assignment: Make sure that your board and points are assigned to the correct compressors and heat stages.

• Heat and Cool OAT lockout temps: From the Home screen, press F1 (AHU), then F5 (SETUP). Move the cursor to C5 (HT/CL Setup) to check the Lockout temperatures.

• Number of stages are not set up or set up incorrectly: From the Home screen, press F1 (AHU), then F5 (SETUP). Move the cursor to C9 (Dehum) to check Dehum Stages.

If you are experiencing dehumidification problems with your COPELAND E2, check the following settings:

• Dehumidifier source not set up: From the Dehum screen (Home > F1 > F5 > C9), verify what the sensor source is.

• Temperature setting for DEHUM OCC or DEHUM UOC is set too high: From the same screen, check the minimum temperature setting.

If the lights will not come on in your COPELAND E2 lighting control system, follow these steps:

1. Make sure you have a Time Schedule set up. A Time Schedule is separate from Lighting Control. Set up the Time Schedule first and then assign it to a Lighting Control.

2. Set up a Time Schedule and go to Lighting Control. Choose the desired application and press F5 (SETUP). Move the cursor to C7 (Inputs) and highlight the Board field. Press F4 (LOOK UP), choose the input device and press Enter. Highlight the Point field and press F4 (LOOK UP). Select the type of schedule and press Enter.

3. Make sure the Lighting Control output is assigned.

If the lights controlled by your COPELAND E2 will not turn on with the photocell, check the following:

• Make sure the photocell is configured as an analog input.

• Verify that the type of light sensor is correct.

• If you are using a light level sensor from another E2 controller, set it up on the controller it is associated with in the Global Data section.
