Q-2
Program the IQ 100 Series Transducer Using RS485
Q
Communication Wiring
The IQ 100 Series transducer’s RS485 port uses standard 2-wire, Half Duplex
Architecture. Connect to Master and Slave devices as shown (+ to +, - to -).
Q
Factory Initial Default Settings
When the IQ 100 Series transducer is powered up, for 10 seconds you can connect to
the meter using the Factory Default Settings (even if the Device Profile has been
changed). After 10 seconds the Device Profile reverts to the actual Device Profile in use.
This is one way you can always connect to the meter. The Factory Initial Default Settings are:
Device Address
: 1
Baud Rate
: 9600
Protocol
:
Modbus RTU
Q
Connection Steps
1.
Open Eaton Meter Configuration Software.
2. Click
Connect
on the Tool Bar. The Connect screen opens. Make sure your
settings match those shown on the right.
3. Click

6. Configure
Scaling
settings
based on your application.
7. Click

and select settings based on your application.
Q
Scaling (CT, PT Ratios and System Wiring)
CT
Numerator, Denominator, Multiplier, CT Fullscale (Calculated automatically)
PT
Numerator, Denominator, Multiplier, PT Fullscale (Calculated automatically)
System Wiring
: Use pull-down menu to select.
Number of Phases
: One, Two or Three
NOTE:
Voltage Full Scale = PT Numerator x PT Multiplier
Current Full Scale = CT Numerator x CT Multiplier
IMPORTANT
! Specify Primary and Secondary Voltage in Full Scale (NOT Ratios).
Example CT Settings:
200/5 Amps:
Set the Ct-n value for 200, Ct-S value for 1.
800/5 Amps:
Set the Ct-n value for 800, Ct-S value for 1.
2,000/5 Amps:
Set the Ct-n value for 2000, Ct-S value for 1.
10,000/5 Amps:
Set the Ct-n value for 1000, Ct-S value for 10.
Example PT Settings:
14,400/120 Volts: Pt-n value is 1440, Pt-d value is 120, Pt-S value is 10.
138,000/69 Volts: Pt-n value is 1380, Pt-d value is 69, Pt-S value is 100.
345,000/115 Volts: Pt-n value is 3450, Pt-d value is 115, Pt-S value is 100.
345,000/69 Volts Pt-n value is 345, Pt-d value is 69, Pt-S value is 1000.
