CHAPTER 9: PROGRAMMING GROUP 0 – GLOBAL METER SETUP

OPEN DELTA SYSTEM INSTALLATION PROGRAMMING

A special switch is used to indicate that the electrical system being monitored is a Three-phase WYE or Three-Wire Open Delta System using the connection installation (see Chapter 3). The switch is located in GROUP 0, FUNCTION 3, Pack 1, Switch D.

WARNING: This switch should be set to UP only if the electrical system is a Three-Wire Delta or Open Delta, using 2 PTs. Otherwise, the switch should be set to DOWN. Failure to select this switch results in Phase-to-Neutral readings, as well as incorrect power readings, with the 2PT connection.

Special Open Delta Connection Installation should be followed in the Installation and Operation section (Chapter 3).

SWITCHING COMMUNICATION PROTOCOLS, EI-BUS, MODBUS RTU/ASCII, DNP 3.0

•For EI-BUS protocol: PACK 2, Switch C is DOWN, Switch D is DOWN.

•For MODBUS protocol, ASCII framing: PACK 2, Switch C is UP, Switch D is UP.

•For MODBUS protocol, RTU framing: PACK 2, Switch C is DOWN Switch D is UP.

•For DNP 3.0 protocol: PACK 2, Switch C is UP, Switch D is DOWN.

NOTE: When programming for MODBUS protocol configuration of LIPA (Long Island Power Authority) mapping options may be performed through communication.

9.5 Modbus Plus Capability

When using the MPI Modbus Plus adapter, the meter values should be set to speak to Modbus RTU with a meter address of 0001 and a baud rate of 9600 baud. The Modbus Plus address is programmed into the MP1 Modbus Plus adapter directly.

PRINTING OPTION

To print, access Mode 1 and Mode 2 (see Part I: Installation and Operation). Printing serial options should be disabled when using a multimeter communications connection RS485.

DISABLING PREVENTS:	1.	Printing through the keypad.
	2.	Corrupting data at a computer terminal while multiple meters poll.
	3.	Corrupting printing commands through communications.

This option connects a serial printer to the RS232 port and prints the data. Disable this feature when the meter is not using an RS232 port (i.e., when RS485 or DC outputs are being used).
