AK-SM 800 Stuck on 'Verifying Nodes'

1. Go to Network Nodes, verify only channels being used are enabled

a. Disable any channels not being used

b. Reset AK-SM 800

Missing License

1. Did MAC address revert back to 00 : 0B : 2D : 00 : 4B : 00 ?

a. If yes, AK-SM 800 must be replaced

b. If no, please contact Danfoss Tech Support and supply the MAC address. Tech Support will help

reinsert the license.

2. The controller will still operate regularly, but you won't be able to make any changes to

configuration

a. In need of immediate assistance, you may load in the back-up/old database to bring the license

back.

Host Comm/ Host Count Error

1. Verify the comm configuration (config → comm)

a. Make sure same master IP addresses for every controller and separate slave IP addresses for

each slave controller

b. If DHCP is set to no, verify default gateway and network mask. Every controller will share the

same default gateway and network mask

c. Verify # of SM's on network

2. Verify rotary dial addresses

a. Master unit needs have address 0

b. Each controller must have unique address

3. Verify connection from AK-SM 800 to switch, and switch to network

a. Could be the issue with the cable

b. Power cycle network switch, router, or cell modem

4. Reset AK-SM 800

a. Make sure to reset all slave controllers before resetting master

5. Verify firmware version in each controller. Units should have same version.

Slowness in AK-SM 800

1. Verify firmware version is above v8.074

a. If running an older firmware version, it is recommended to upgrade (latest version is v8.091)

2. Is slowness present when viewing case controller only or any other screen?

a. If only present to case controller info, it could indicate an issue with case controller comm loop

i. Try temporarily breaking loop to few case controllers and see if results are better. You may

also choose to unplug Modbus plug and see if it speeds up

ii. Start adding case controllers back to the loop one-by-one and see at what point slowness

returns. This will indicate where the issue is.

DNS Failure Alarm

1. DNS stands for domain name server, which allows you to type domain name (i.e. google.com)

instead of server IP. If you know the server IP, you may choose to type in the IP and turn DNS off.

2. DNS failure alarm indicates that an alarm transmitted, or attempted to transmit via email from the

AK-SM 800, and there was no feedback from the email server to the AK-SM 800 saying the alarm

was received.

a. Sometimes the server is simply not setup to send this feedback, so if the user did in fact receive

the initial alarm via email, it is nothing more than a nuisance and DNS alarm can be disabled.

b. Otherwise, verify the DNS name entered under the Config → Alarms → Connections section of

the SM800 is correct.
