Introduction:
The AC voltage input signal conditioners are high
performance instruments that measure AC voltages in 4
ranges which are as follows: 400 mV, 4 Volt, 40 Volt and 400
Volt. Key features of the signal conditioners are built in active
attenuator, scalable analog output and a simple RS232
interface for scaling analog output and range selection. The
RS232 interface may also be used for digital transmission of
input signal to a computer or a PLC. Additional features
include three way isolation between DC power, signal input
and analog output/RS232.
PLEASE OBSERVE THE INPUT SIGNAL
CONNECTION SPECIFIED IN THE SECTION
BELOW. THIS DEVICE MUST ONLY BE INSTALLED BY
A PROFESSIONAL ELECTRICIAN.
Power Input and Analog Output Setup:
To connect the signal input proceed as follows:
1. Connect a DC power supply with an output voltage
between 10 to 32 Volt DC to the signal conditioner (J1).
Note: If power supply used has current limiting, it may not
be able to power the signal conditioners if the available output
voltage is around 10 Volt, since the peak current may reach
1 to 5 amp for a few milliseconds.
2. Determine the maximum voltage to be measured.
5
3. Determine the appropriate input signal range, i.e. 400 mV,
4 Volt, 40 Volt or 400 Volt. Also ensure that the frequency of
AC source is within the specified limits.
4. Ensure that if the selected range is different from the default
then change the internal range by using the Setup Software
and select the appropriate range.
5. Connect the signal input to screw terminal, and ensure that
the screws are tight. Failure to do so may cause electrical
shock should the wires become loose and come out of the
screw terminal.
6. To verify that the set up is correct, you may connect a DVM
to the analog output. Once connected, power the signal
conditioner and apply a known voltage from an AC source to
input. Measure and compare with expected values. To
custom scale the analog output proceed to the next step.
7. To view/change the scaling that relates the analog output to
signal input: connect the RS232 output of the signal conditioner to
an available serial port of a computer. The cable and the DB9 or
DB25 connectors are available as an option.
8. Turn on the computer, start Windows 3.0 or higher and run
the Signal Conditioner Configuration Setup Program.
9. Start the configuration program, you need to indicate which
serial port is to be used for serial communication by checking
the appropriate check box on the opening menu.
Note: It is not necessary to know the serial communication
protocol. i.e. baud rate, parity, 7/8 data bit and stop bit; the
program will determine this information automatically.
However, it is good practice to mark the protocols used on the
signal conditioner label if different from default.
10. Once the program starts it will automatically detect the
signal conditioner configuration and will display a window of
available options. To view the signal input click on the
display on/off.
11. To change analog output scaling choose analog output
scaling and enter the desired values.
12. Once the custom scaling is finished, ensure that Send
Configuration is clicked, otherwise the changes will not take effect.
13. The input/output scaling may be fine tuned, while both
communication and analog output are active. In fact you may
make a change to the analog output in the configuration
program, and watch the DVM connected to analog output of
the signal conditioner follow the new settings.
14. You may save or print a particular configuration by
selecting the file menu. It’s always a good practice to both
print and save the scaling of each signal conditioner.
6
15. If the program is not able to establish communication then
an error message is displayed. This happens either when the
wrong serial port is specified or when the cable is
disconnected.
16. The procedure to disable Continuous Mode and change
the iDRN to Command Mode is as follows:
Using HyperTerminal, or any serial communication program,
type: Ctrl + S
To change the device to Command Mode, type: ^AE
To change the Bus Format Register, type: *W0814
To reset the device,type: *Z01
Cycle power to the unit.
