Figure 1 Single Phase, 2-wire Configuration
Figure 2 Single Phase, 3-wire Configuration
The meter uses three smart setup registers to configure all smart input modules. Input modules IW04/5 require only smart register 1 to be set up. These modules produce four output registers.
One of these registers can be transferred to Channel 1 via Code 2, the same or another register to Channel
2 via Code 4, the same or another register to Channel 3 via Code 5, and the same or another register to Channel 4 via Code 6.
Input modules IW01/2/4/5 have a zero crossing detector that is available for direct line-frequency measurement in Channel 2. The following resolution settings can be selected in Code 4:
0 to 99.999 Hz, 0.001 Hz resolution.
Set Code 4 to [30X].
0 to 999.99 Hz, 0.01 Hz resolution.
Set Code 4 to [31X].
Note, the direct line-frequency measurement setting for channel 2 is a hard-wired option and, if selected, means channel 2 is not available for selecting an output register.

Channel 3 to display voltage (V rms).
Channel 4 to display power usage (kW).
Steps 1 to 6 describe how to select the current gain setting through smart register 1.
Steps 7 to 13 describe how to select the output registers for channels 1, 2, 3, or 4 as required.
Steps 14 to 16 describe how to select line-frequency for channel 2.

This setting enters the smart register 1 code setup menu.
Note the output register map is different for each smart input module.
This menu provides settings unique to input modules IW01 to IW04.
This takes you back to the Code 2 menu.
Note the output registers in the 3rd digit are specific to IW04/5. These registers vary for each different smart input module.
The next step is to select the appropriate output register from the output register map for a selected channel.

DI-503 WHITE TRIM 2/May/02
Our customer has a powerful single phase motor connected to the 120 V rms supply. The motor can draw up to 200 A rms under full load. As part of the supervisory programme, the owner requires to monitor the line voltage, current draw, and resultant power usage simultaneously.
A Tiger 320 Series triple display meter is installed to display:
Channel 1:
Current (I rms) on the top (primary display).
Channel 3:
Voltage (V rms) on the middle display.
Channel 4:
Power usage (kW) on the bottom display.
CH1
CH3
Channel 2:
Configured to read the line frequency at 0.01 Hz resolution (displayable in the view mode).
Because there is a 5 A rms maximum current limit on smart power module IW02, a 200:5 current transformer is used to sense the load current.
CH4
The meter is calibrated at the factory to the following default settings with a scale factor of 1 and an offset of 0:
30,000 counts for 5 A rms.
1000 counts for 100 V rms.
10,000 counts for 500 W.
To accomodate the customers specifications, the offsets remain at 0, but the scale factors must be adjusted to display (See Recalibration Procedures on Page 6):
20,000 counts for 200 A on CH1.
1,200 counts for 120 V on CH3.
24,000 counts for 24 kW on CH4.
The new scale factors are calculated as follows:
1 CH1 Scale Factor
Our 200 A load is reduced to 5 A to suit the smart input modules maximum current limit by passing it through a 200:5 current transformer (CT).
The original factory setting was 30,000 counts for the maximum load.
We now want to display 20,000 counts for the same load. Therefore, the scale factor is calulated as:
CH1 Scale Factor =
20,000
30,000
= 0.666 (I rms)
2 CH3 Scale Factor
Our original factory setting for the 100 V line voltage was 1,000 counts. Applying a new line voltage of
120 V to the original settings for CH3 displays 1,200 counts on the meter. Therefore, no adjustment is necessary and the scale factor remains unchanged at 1.0.
3 CH4 Scale Factor
Our original factory setting for the power reading on CH4 is:
5 A load & 100 V line voltage = 500 W over 10,000 counts
Our load has now increased to 200 A, which is passed through a 200:5 CT effectively retaining a 5 A load.
Our line voltage has increased to 120 V displayed over 1,200 counts. This means we now have:
5 A load (actual 200 A) & 120 V line voltage = 600 W over 12,000 counts
We wish to double the resolution of the power reading on the display to 24,000 counts for the maximum load. Therefore, the scale factor is calculated as:
CH4 Scale Factor =
24,000
12,000
= 2.0

* APPLICATION CONCEPT
Power factor gives an accurate measure of load change, particularly at low to medium loads, where current is dominated by it's magnetizing element. Where prompt action is required the optional relays in the Tiger 320 Series meter can be used for protection against broken belts, pump cavitation, conveyor stalling and general overloads.
