The following troubleshooting guidelines detail the process of

verifying proper setup of an AK-CC 550A when encountering

communication/oﬄine issues with an AK-SM 800 series controller.

System Manager Programming

• Complete Rescan

- On Network Nodes screen, select ‘Press for complete rescan’

*Also complete rescan if any of the items below required

adjustment

• Ensure proper channel enabled on Network Nodes screen of

system manager

- ‘Channel LONWORKS’ for LON RS485 comm loop

- ‘Channel MODBUS-RS485’for Modbus comm loop

• Verify no Duplicates in System Manager

- Check under Network Nodes->Duplicates

- If duplicates exist, identify case controller with mistaken

address, and update

• Verify address has been assigned to case controller in

program

- Verify under Conﬁguration->Control->Refrigeration-

>Addresses

AK-CC 550A Hardware

• Verify part # of AK-CC 550A. This will be printed on front of

controller below display

- For 084B8030, verify 230Vac to terminals 1&2

- For 084B8036, verify 115Vac to terminals 1&2

AK-CC 550A Programming

• Ensure address is set correctly, via parameter o03.

• Ensure application is set correctly, via parameter o61.

Comm Loop Wiring

• Verify intended form of communication to be used (Modbus

or LON RS485)

- For Modbus communication:

- Ensure comm wires are landed on terminals 57&58.

- Modbus loop is polarity sensitive, ensure polarity is

consistent throughout loop

- Ensure any other Modbus devices on the loop use 38400

baud rate

- For LON RS485 communication:

- Ensure comm wires are landed on terminals 52&53

- Ensure EKA 175 comm card is installed in port below

display.

- EOL resistor

- For 1 loop from system manager, ensure 120 ohm resistor

at end of loop and switch above comm plug in ‘On’

position

- For 2 loops from system manager, ensure 120 ohm resistor

at end of each loop and switch above comm plug in ‘Oﬀ’

position

• For either comm type, max distance is 4000’. Beyond this

distance, a repeater is needed

• For either comm type, max # of case controllers is 120 per

system manager

• For either comm type, an EIA 485 rated cable should be used
