Delaying Setpoint Operations Delaying Setpoint Operations Delaying Setpoint Operations Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring a
setpoint trigger for a longer time before making a decision on whether the
expected event occurred or not. When a delay is specified, the logical
controller will change the setpoint status only if all conditions are asserted for
a period at least as long as the delay time.
Using Setpoint Events Using Setpoint Events Using Setpoint Events Using Setpoint Events
When a setpoint status changes, i.e., a setpoint event is either asserted or
de-asserted, the following happens in your device:
1. The new setpoint status is logged to the setpoint status register that can
be monitored via communications from the user application software in
order to give a real-time indication on the expected event.
2. The operated setpoint status is latched to the setpoint alarm register
accessible through communications. The register holds the last setpoint
alarm status until it is explicitly cleared via communications.
Recording Setpoint Events Recording Setpoint Events Recording Setpoint Events Recording Setpoint Events
Time-tagged setpoint events can be recorded to the submeter event log if
you select it as the setpoint action. The Event recorder logs any setpoint
transition event: both when the setpoint is operated, and when it is released.

The Multi-Mon provides four total/summary energy and six parallel tariff
energy and maximum demand registers for each individual submeter. The
registers can be linked to any internal energy source or to another submeter.
The meter tariff structure supports six different tariffs using an arbitrary tariff
schedule. A total of four types of days and four seasons are supported with
up to eight tariff changes per day.
The meter can provide automatic daily profile recording for total and tariff
energy and maximum demand registers. The device memory is sufficient to
store daily profile data for 120 days.
By default, the first billing register in your meter is linked to the kWh IMPORT
accumulator, and the daily profile recording is enabled for the kWh register.
Other billing registers are not operational. To activate the remaining registers
or to change the profile for the first billing register:
1. Link the Summary/TOU registers to the respective energy sources, and
then configure the options for these registers like whether the only
totalization or both total and tariff registers would be used, and whether
daily profiling should be enabled for the energy usage and maximum
demand registers.
2. Configure the daily tariff schedule for all types of days and seasons
using the TOU daily profiles.
3. Configure the season tariff schedule using the TOU calendar.
