Setpoint Configuration (9330 and 9350)

Setpoints provide extensive control, secondary protection and analysis capabilities
by allowing you to initiate an action in response to a specific condition. Some
possible applications for the Setpoint module include: demand control, power
quality monitoring, fault detection, activating alarms, and gated logging functions.

For the 9330 and 9350 meters, the Setpoint modules monitor certain ‘over’ and
‘under’ conditions for sliding window demand, current, voltage and power factor.

Setpoint Module Settings

There is no need to change any of the Setpoint modules’ setup registers for normal
operation of the meter.
