About the PM-600
PM-600 is a power meter module by Square D, which is part of the Schneider Electric family. PM-600 is part of the PowerLogic 3020 series of power meters. PM-600 has instrumentation and falls within 0.3% accuracy. Default values for PM-600 are: Protocol - Powerlogic, Network address - 1, baud rate - 9600, parity - even, CT Primary (3-Phase) - 5. Default password is set to 0, and Pulse Constant is also 0. Unique to PM-600 is in KYZ Mode is disabled.
PM-600 features full instrumentation, an RS-485 communications port, wiring diagnostics, ASI C12. 16 accuracy. PM-600 should be handled in a safe manner based on the hazard of explosion, burn, or electrical shock. PM-600 should only be installed by qualified electrical technicians, and only after fully reading all instructions. Mounting the PM-600 make sure to allow for space from walls and other objects of at least 4" on the terminal end, and 3" on the vented side.
The PM-600 features connections such as voltage 3 phase inputs, power terminal control, KYZ pulse output, current input (3-phase), communication ports (display), and RS-485 Communications Terminals. The 3-Phase inputs are located in a row of 4 at the top of the unit, the control power terminal and KYZ pulse output fall below it to the left and right respectively. The next two rows of 3 are the 3-phase current inputs. To the left of the bottom row of current inputs is the RS-485 communication terminal. The RS-485 communication terminal is wired by pin thusly: 5, in+, 4, In-,3 out+, 2 out-, and 1 shld.
Square D manufactures the PowerLogic 3020 Power Meter (PM-600). There are many default settings on the power meter. The allowed values for the protocol are PowerLogic, Modbus, and Jbus, and the default is PowerLogic. The allowed values for the network address are 0 to 199, and the default is 1. The allowed values for the baud rate are 1200 to 19200, and the default is 9600. The allowed values for the parity are “even” and “none”, and the default is “even”. The allowed values for the CT primary are 1 to 32, 767, and the default is 5. The allowed values for the CT secondary are 1 and 5, and the default is 5. The allowed values for the PT primary (3-phase) are 1 to 1,700,000, and the default is 120. The allowed values for the PT secondary are 100, 110, 115, and 120, and the default is 120. The allowed values for the system type are 40 (4-wire), 31 (3-wire, 3 CT), and 30 (3-wire, 2 CT), and the default is 40 (4-wire). The allowed values for the nominal frequency are 50 Hz and 60 Hz, and the default is 60 Hz. The allowed values for the pulse constant are 0 to 327.67 kWH, and the default is 0 kWH. The allowed values for the password are 0 to 9998, and the default is 0.
