Electrocorder Model: EC-2VA
2 of 3
When the required information has been input, download to the
connected Electrocorder by clicking the ‘Write Setup’ icon. The
Electrocorder is now ready to monitor voltage.
When the Electrocorder is recording a flashing red light will
show and when it has completed recording, a green light will
appear on the unit. The database contained within Electrosoft
will also advise that the unit has completed recording and is
ready to be collected. To download the recorded data connect
the Electrocorder to the PC serial port and click the ‘Read Setup’
icon. The recorded data is displayed for analysis.
This document is produced in conjunction with the Help file
contained in Electrosoft, which contains a detailed explanation of
all features and contains information, which should be
studied prior to using this product.
USB to RS232 Serial Converter
If you have purchased a USB to RS232 converter, you must
install the drivers. You can use the drivers shipped with the
program which may be in the USB sub-folder within the Program
Folder, normally C:\Program Files\Electrosoft\USB. You can
download them from the website www.electrocorder.com or use
the disk, if one came with the converter.
The following describes the XP installation, other operating
systems will vary slightly. When you plug the converter into the
PC, it will detect it and identify the new hardware as UC232R,
Windows will then ask to search for the drivers, choose “Yes, this
time only”, then on the next screen choose, “Install from a list
location” then specify the location of the drivers, possibly the USB
sub folder, in the installation folder, or wherever you saved the
files to when you downloaded from the internet.
When installed, make a note of the serial or COM port number
the converter has been assigned to and when you run Electrosoft,
select the appropriate serial port or COM port number.
SAFETY TIPS
The 2-core voltage input is labelled ‘L1’ and the current input A1.
For correct operation this recorder must have a proper Neutral
(N) connection. Brown is the live conductor and blue the neutral.
1. If possible electrically isolate the conductors to which you
wish to connect.
2. First, using insulating gloves place the current input sensor
around the conductor to be monitored. It must only be used
around an insulated conductors, this sensor is rated to 600V
CAT II.
3. Using insulating gloves, connect the each voltage cores in turn
to the electrical bus-bars.
4. The voltage lead is double insulated, 300V. Always check
that the lead is in good condition, if it becomes damaged, then
it MUST be replaced.
Single Phase 2 Wire Systems
(using inputs ‘L1’ and ‘A1’)
Ensure the logger has been set-up with a PC to log for a specific
period.
Using insulating gloves place the current sensor around the
voltage busbar being monitored, the simply connect the brown
wire (of L1) to System Live/Hot and connect the
blue (of L1) to System Neutral (‘N’). The logger will automatically
start to record when voltage on input L1 is detected. If you do
not wish to record current (or cannot) then you do not have to
connect A1; the logger will then only record voltage.
We would not recommend connecting the Neutral (N) to anything
other than System Neutral. We do not recommend connecting
this input to an external System Ground (G) or Earth (E) as the
floating voltage on the Neutral (internal Star-point) could trip
sensitive Earth Fault or Earth Leakage protection equipment.
Power Measurement
(Using inputs ‘L1’ and ‘A1’)
Ensure the logger has been set-up with a PC to log for a specific
period.
To record the power being taken on a voltage busbar or cable,
firstly using insulating gloves place the current sensor around
the voltage busbar being monitored, then connect the blue wire
of L1 to the system Neutral (‘N’) then connect brown wire (of L1)
to that voltage busbar and . Ensure the current carrying cable
is insulated! The logger will automatically start to record when
voltage on input L1 is detected.
We do not recommend connecting this input to an external
System Ground (G) or Earth (E) as the floating voltage on the
Neutral (internal Star-point) could trip sensitive Earth Fault or
Earth Leakage protection equipment.
