To change the system type, complete the following steps:
1. Press the MODE button until the red LED next to [Setup] is lit.
The circuit monitor displays “ConFig.”
2. Press the PHASE [Enter] button to select the Configuration option.
The circuit monitor displays the password prompt “P - - - -.”
3. Enter the password.
To enter the password, use the SELECT METER [Value] buttons to
increase or decrease the displayed value until it reaches the password
value. Then press the PHASE [Enter] button.
4. Press the PHASE [Enter] button until the red LED next to [Sys. Type]
flashes.
5. Press the SELECT METER [Value] buttons until the system code
matching your system type is displayed.
Refer to table 4-2 to determine the system code for your system type.
6. Press the MODE button once.
The red LED next to [Accept] flashes. The red LED next to [Sys. Type]
glows steadily.
7. To reject the new system type, press the PHASE [Enter] button once.
The circuit monitor returns to METERS mode.
8. To accept the new system type, press the SELECT METER [Value] button
to change from No to Yes. Then, press the PHASE [Enter] button.
The circuit monitor restarts.
Setting the Demand The circuit monitor supports several methods to calculate average demand
Interval real power. The default method is the thermal demand method. For a
description of available demand calculation methods, see Demand Readings
in the Circuit Monitor Reference Manual.
One optional method is the demand synch pulse input method. In this
method, the circuit monitor accepts an external synch pulse from another
demand meter. The circuit monitor then uses the same time interval as the
other meter for each demand calculation. For a more detailed description of
the demand synch pulse input method, see Demand Synch Pulse Input in
the Circuit Monitor Reference Manual.
Note: The circuit monitor must be equipped with an input/output module to use the
Demand Synch Pulse Input feature.
The thermal demand (default) method and the demand synch pulse input
method can be set up from the circuit monitor front panel. Other methods
must be set up over the communications link, or using the front panel
diagnostics feature (see Reading and Writing Registers from the Front
Panel in the Circuit Monitor Reference Manual for instructions on using this
feature).
