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
