IM300 Intelligent Power Monitoring Instrument
93
moment, but the internal measurement of energy value continues to
accumulate. If you want to refresh the reading total value of energy, the
upper computer must sending the unfreeze command.This facilitates the
user's unified meter reading
energy freeze and unfreeze status register (40060):
The high byte is 00, BIT1 of low byte denote energy freeze and unfreeze
status, other bits are inefficient.
1 denotes freeze and 0 denotes unfreeze.
System frequency selection (40062):
5000 represents the system default frequency is 50Hz, 6000 represents
the default frequency is 60Hz.
Direction of CT wiring
(40067,40068):
High byte of 40067 is the direction of A-phase CT wiring; Low byte of
40067 is the direction of B-phase CT wiring. High byte of 40068 is the
direction of C-phase CT wiring. 0x00 denotes forward direction, 0xFF
denotes opposite direction.
Telemetry wiring (40070): 1 to 5 show specific wiring in the following table:
Wiring Code

1
3-phase 4-wire 3CT (3P4W / 3PT + 3CT)
2
3-phase 4-wire 1CT (3P4W / 3PT + 1CT)
3
3-phase 3-wire 3CT (3P3W / 3PT + 3CT)
4
3-phase 3-wire 2CT (3P3W / 3PT (or 2PT) + 2CT)
5
3-phase 3-wire 1CT (3P4W / 3PT + 1CT)
Outputs function settings (40081): 1 ~ 2 respectively denote two relay
outputs in the following table:

The time of back-light (40090): 0 to 30 minutes, where 0 represents
constant light.
