Description
40041
Word Order
Word Order controls the order in which Multifunction Meter receives or sends fl oating - point num-
bers:- normal or reversed register order . In normal mode, the two registers that make up a fl oating
point numbers are sent most signifi cant bytes fi rst. In reversed register mode, the two regis-ters that
make up a fl oating point numbers are sent least signifi cant bytes fi rst. To set the mode, write the
value ‘2141.0’ into this register-the instru-ment will detect the order used to send this value and set
that order for all ModBus transaction involving fl oating point numbers.
40043
CT secondary
This address is used to read and write the CT secondary value. Write one of the following values to
this address.
1: 1A CT secondary
5: 5A CT secondary
writing any other value will return an error.

128 (Decimal): Limit output on Relay1. Writing any other value will return an error.
40049
Pulse 1 / Limit 1
parameter
select
This address is used to assign the Parameter to Relay1
If Limit option is selected refer TABLE 4 for parameter number & if Pulse option is selected then refer
TABLE 6.
40051
Limit 1
Trip Point
This address is used to set the trip point in %. Any value between 10 to 100 for Lo- alarm & 10
to120 (refer TABLE 4) for Hi-alarm can be written to this address.
Writing any other value will return an error.
40053
Limit 1
Hysteresis
This address is used to set the hysteresis between 0.5 to 50.0%.
Writing any other value will return an error.
40055
Limit 1

Password
This address is used to set & reset the password. Valid Range of Pass-word can be set is 0000 -
9999.
1) If password lock is present & if this location is read it will return zero.
2) If Password lock is absent & if this location is read it will return One.
3) If password lock is present & to disable this lock fi rst send valid pas word to this location then
write “0000” to this location
4) If password lock is present & to modify 4X parameter fi rst send valid
password to this location so that 4X parameter will be accessible for modifi cation.
5) If for in any of the above case invalid password is send then meter will return exceptional error 2.
