Cannot access to Web
Has the network been connected successfully? Please check to make sure that the Ethernet cable
is securely connected and that the PMC-592 and PC are connected to the same IP network.
Please check to make sure that the IP address is entered correctly via the HMI.
If the PMC-592’s Ethernet configuration are correct, please check to make sure that the PC’s IP
address is on the same subnet. If confirmed, please try to
Ping
the PMC-592’s IP address and
other “known” network nodes from inside a Command Shell of the PC to make sure that the PC’s
Ethernet configuration is correct. If the problem persists, please contact your Network
Administrator or CET Technical Support via

The accuracy of an entire CT Strip doesn’t meet stated specification
This could happen in older PMC-592s if a CT Strip is inserted to a Branch Input that hasn’t been
calibrated during production. Please check the firmware version to make sure that it is V1.00.03 or
above. For older PMC-592 with firmware version V1.00.02 or earlier, calibration is performed only
on the number of Branch Circuits specified during purchasing so additional CT Strips are not
supported in the field.
