e-Tracker portable energy monitor operating and maintenance manual

Features:

Mains or 16 day battery operation* Magnetic back for easy mounting Multiple memory locations Pulse input Optional voltage connections CT amps range indicator

Clip-on CTs for fast safe instalation EV-Trac electrostatic phase identifier

Optical or magnetic gas meter reader available

Deltrax5 software is Windows 7 compatible

The e-Tracker also displays average and peak demand to enable the calculation of load factor. Deltrax5 software highlights demand excursions and potential unauthorised consumption.

*In battery only operation the e-Tracker will only give accurate current measurements, all other readings will be assumed.

e-Tracker is a portable kWh meter which monitors the incoming power supply to show the pattern of demand over an hour, day, week or month. As e-Tracker is portable you have the flexibility to use it for measuring sub-circuits and other specific equipment without the need to have a fixed sub-metering solution.

What is e-Tracker?

Sold as a full kit comprising:

e-Tracker with integral EV-Trac 1Ø -3Ø voltage reference converter

Set of 3 F30-1000 dual range Flexeclamp CTs 30cm - 1000Amps /200Amps

How is data collected?

e-Tracker records and stores all data, which is then downloadable via USB memory stick into our Deltrax5 software. This data is graphically displayed on a monthly, weekly or daily basis or alternatively processed in Excel format.

Installation and set up

Isolate any accessible un-insulated conductors during installation. Clip CTs to all appropriate cables/conductors with all arrows facing the load. All transducers including voltage reference inputs (if used) should be fitted and connected to e-Tracker before e-Tracker is switched on.

Practical and accurate connection options for single and 3 phase use:

Use e-Tracker with its fused voltage clips for maximum accuracy on all parameters

3Ø direct voltage measurement

The set of colour coded fused voltage crocodile clips must be securely attached to pick up the phase voltages with the colours matching the attached CTs.

Red/Brown = Line 1

Yellow/Black = Line 2

Blue/Grey = Line 3

No neutral connection is required although e-Tracker can be earthed Green/Yellow lea connection ensures high accuracy recording.

d. Direct voltage

EV-Trac 3 phase volt reference conversion from a single phase socket outlet

3Ø EV-Trac voltage pickup

e-Tracker’s internal 1Ø- 3Ø converter is automatically applied when three CTs are connected to cables with voltage reference taken from a 1Ø source all supplied from the same distribution transformer.

Should automatic identification fail the EV-Trac electrostatic probe may be used. Please note this can only be effective on un-armoured phase cables.

e-Tracker calculates the three equivalent Line-Line voltage vectors and assigns them to the correct phases.

Battery only operation measuring current and calculated kVA demand profiles

3Ø current recording

This simple method is often very adequate for determining day/night consumptions patterns, demand peaks, phase balance and calculating kVAh totals. In this mode e-Tracker operates totally from its battery only and has an adjustable nominal voltage (default setting 415V).

e-Tracker will produce line current profiles and derive kVA profiles.

Single phase recording

Single phase with the voltage reference derived from a wall socket etc. Alternatively Tracker will record current for up to 2 weeks on battery only. In battery mode Tracker has an adjustable nominal voltage (default setting 240v.)

Pulse count input (minimum integration period 1 min)

When using the optional pulse input interface, Tracker can accept a volt free contact closure from any suitable gas, water or electric metre. Alternatively the Magpeye optical metre reader may be connected. Normal analogue inputs are usable at the same time as pulse input.

Trouble shooting

If you are experiencing difficulties with your e-Tracker, please consult the points below. However if your problem is still not resolved please contact Marshall-Tufflex Energy Management on +44 (0)1424 856610.

If the unit will not switch on and has no display try the following:

1) Your battery could be flat, please place on charge for at least half a day with on/off switch in off position, use mains lead to charge (Note ensure 3Amp fuse in 13Amp plug is okay).

2) If charging fails to cure the problem, either the battery is flat or your e-Tracker program could be corrupted. Your unit would need to be returned to factory for reprogramming or to fit a new battery.

3) If charging fails to cure the problem, the internal fuse may have blown. Your unit would need to be returned to the factory for investigation.

Pleasenote:afaultybattery,corruptprogramorblowninternalfusecangivethesame symptoms.

On screen error messages:

CT’s odd

At least one of the three CTs does not match, or at least one of the three CT cables is damaged thus causing the “CTs odd” message. In turn test each of the CTs using CT1 input only, the rogue CT can be identified as it will produce a different Amp range to the other CTs (when going through the e-Tracker's set-up procedure).
