• PC configurator software (model: R3CON)
Downloadable at M-System’s web site.
• Clamp-on current sensor (model: CLSE)
The clamp-on current sensors, not included in this product package, must be ordered separately. Required number depends upon the system configuration.
• Network module (model: R3-Nx)
In order to have the reset function from the host device, use V.2.00 or higher versions of the R3-NC1, -NC3, -NE1 and -NM1. With other versions and models, the resetting is possible using the R3CON PC Configurator.
For use with the R3-NLx, consult M-System.

MEASURANDS
• 16-word Mode (standard)
Measurands and assigned word numbers are specified using the R3CON PC Configurator.
Max. 16 words per module (slot). 1 word = 16 bits, 2 words
= 32 bits
• 32-word Mode (option /D)
Measurands and assigned word numbers are specified using the R3CON PC Configurator.
Max. 32 words by virtually assigning addresses (n) and (n+1) per module. 1 word = 16 bits, 2 words = 32 bits
Be sure to use the R3-BSW base with free address setting capability. DO NOT assign the address (n+1) to any module.
A duplicate address will cause malfunctions.
■
RESET
Measurands to be reset can be specified among: all energy values, MAX / MIN current values, MAX / MIN values other than current and AVG (demand) values.
Refer to ‘I/O DATA DESCRIPTIONS’ in the R3-WTU instruction manual for resetting from the host device.
For detailed information for the selection of measurands and other settings, refer to the R3CON Users Manual.
