Select your submeters (both metering and totalization) in a sequence without
gaps so that your device does not occupy unnecessary network addresses.
If you connect a number of devices to a serial network, allocate a range of
addresses for each device so that they do not overlap. For example, if you
use three devices with 12 submeters in each one, assign the base address 1
to the first device, the address 13 to the second, and the address 25 to the
third device so that they will occupy three non-overlapped address ranges 1
through12, 13 through 24, and 25 through 36.

For proper device operation, select the correct power frequency (see Basic
Device Settings ) and set the correct primary ratings for device current inputs
(see Channel Assignments ) before you connect the device to your network.
Energy/TOU System Energy/TOU System Energy/TOU System Energy/TOU System
The Multi-Mon provides 4 separate billing energy (total/summary and
parallel tariff and maximum demand) registers for each individual submeter.
Each register can be linked to any internal energy source or another
submeter. The first billing register in your meter is linked to the kWh
accumulator by default. Other registers are not operational unless you
configure them through the Energy/TOU Setup (see
Configuring Billing
Energy and TOU Registers ).
Device Diagnostics Device Diagnostics Device Diagnostics Device Diagnostics
Device diagnostic messages may appear as a result of the Multi-Mon built-in
diagnostic tests performed during start-up and device operation. See
Device
Diagnostic Codes in Appendix F for the list of diagnostic codes and their
meanings.
The device diagnostics status is stored in a non-volatile register, which may
be inspected and cleared via Power Software, from the meter display or from
a user application. All diagnostic events with time stamps are also recorded
in the device Event log and can be inspected via Power Software (see
Retrieving the Event Log in Chapter 4).
See Diagnostics Display and Reset in Chapter 3 on how to inspect and clear
the device diagnostics status from the display. See Viewing and Clearing
Device Diagnostics in Chapter 4 on how to inspect and clear the device
diagnostics status via Power Software. Refer to the Multi-Mon Modbus
Reference Guide for the diagnostic register address and layout.
In the event of a device fault, check the fault reason and clear the device
diagnostics. In the event of a time fault, update the device clock. In the event
of a configuration reset, check the setup affected by the fault via the device
Event log, and then verify the setup data.
Hardware failures are normally non-critical recoverable faults that do not
cause a system failure but may cause data loss. Hardware failures are often
caused by excessive electrical noise in the region of the device.
If the device continuously resets itself, contact your local distributor.
