3 PRODUCT OVERVIEW
3.1 Description
The Ampcontrol Outlet Test System – Earth Leakage (OTS-EL) provides a fully automated outlet earth
leakage testing facility. The OTS-EL completely eliminates paper-based record keeping by concurrently
updating a historical database with the latest test data.
The OTS-EL is comprised of an OTS-EL module, embedded within the outlet electrics, and an OTS
Comms Module, mounted on the door to provide Bluetooth connectivity to the outlet tester.
All tests are initiated wirelessly via the OTS Application Software, which is installed on compatible
Bluetooth enabled devices. Each outlet is able to be individually targeted.
All local test records are managed within the OTS Application Software until the tablet performs an
authorised sync with the AWARE cloud storage. When this occurs all local test reports are uploaded to
the cloud, and then all Assets and Users are refreshed for selected site. All OTS test records can be
accessed by anyone with internet access and authorisation (user account).
The OTS-EL will measure both the contactor opening time in addition to the true earth leakage clearing
time (time for back EMF voltages to fall below ELV).
3.2 Key Features
The OTS-EL has the following key features:
Fully automated, outlet protection function testing
Wireless outlet testing
Earth Leakage (EL) protection testing (contactor operating and back EMF clearing times)
Test data logging (Uploads to cloud storage)
DIN rail mounted
3.3 Application
The OTS-EL System can be installed into Ampcontrol Substations, Distribution Boards and Outlet
Control Boxes. The OTS-EL greatly simplifies the statutory testing process, performing a hands-free,

4.3.2 OTS Comms Module Mechanical Installation Information
Figure 4.4: OTS Comms Module
The Comms module provides Bluetooth connectivity to the Tester. It is intended to be mounted onto
the back of an outlet door or enclosure, covering a 22.5mm OD hole. The hole needs to align with the
PCB aerial on the Comms module. Without this hole, the steel of the enclosure would form a shield,
preventing Bluetooth communications to the tester. To improve the connectivity of the Bluetooth device,
the hole in the enclosure should be positioned such that it faces the location where the testing officer is
most likely to stand when initiating the test procedure.
The Communications Module must be oriented with the RJ45 port pointing downwards to ensure both
LEDs on the Comms Module align with their corresponding position on the external label.
To install the Comms Module, simply pull the plastic off of the high strength adhesive tape and stick it
to the back of the door, aligning the circle on the PCB with the hole in the enclosure.
To maintain the IP rating of the enclosure the included label must be placed externally over the hole.
The location of the two LEDs on the OTS Comms Module can be seen in Figure 4.5.

4.4.4 EL Test Connections (Terminals 4 & 5)
The Earth Leakage Test works by closing an internal normally open contact for the duration of the test.
This contact is intended to be wired in parallel to an existing earth leakage test circuit that passes an
AC current through the outlet’s earth leakage toroid.
NOTE
The installer is responsible for ensuring that the test resistance is of a
suitable magnitude to provide a meaningful test.
It is recommended that the resistance value is chosen such that the test
current is between 110% and 120% of the trip level of the earth leakage
protection relay (AS/NZS 2081 Appendix E4, AS/NZS 4871.1:2012
Clause 2.6.2.4).

5 PRODUCT OPERATION
All tests are initiated wirelessly through Bluetooth from the AmpINTEL PowerSAFE OTS software. The
AmpINTEL PowerSAFE OTS Application software is compatible with Android versions 4.3 and above.
As the OTS application has been developed and tested on the Samsung Galaxy Tab A with Android
version 6.0.1, Ampcontrol can only guarantee compatibility with this device.
CAUTION!
Ampcontrol cannot guarantee correct operation of the AmpINTEL
PowerSAFE OTS application if a non-compatible smart device is
utilised.
During a test, the results will be displayed on the tablet and a report will be generated upon completion.
These test reports are stored on the tablet until the tablet gains network access. At this point the test
reports are uploaded to the dashboard, a site specific cloud based storage platform.
Once these reports have been uploaded, all reports except for the most recent will be removed from the
tablet. The most recent report is saved on the tablet because, at the beginning of each new connection,
the OTS-EL will check to make sure there are no discrepancies between the results obtained from the
last test and those stored on the tablet. If there are any differences the test report will be updated to
those stored in the OTS-EL. If the reports are different (i.e. the last test was conducted on a different
device) a new test report will be generated with the data stored on the OTS-EL. This is of particular use if
there were any issues with the tablet or Bluetooth connection during testing.
For more information on the operation on the OTS-EL Android Application or the Dashboard please refer
to the relevant user manual.
NOTE
The Bluetooth range is limited to a maximum of approximately three
metres (3m). This distance is an advised maximum, various factors
will influence the connection distance.

5.1 Earth Leakage Protection Function Test
The Earth Leakage test can only be initiated with the outlet energised. When the EL test is initialised, the
OTS-EL will energise the existing external EL test circuit. This simulates an EL current to be detected by
the outlet’s earth leakage toroid.
NOTE
The OTS itself does not generate the test current; it operates in parallel
to the existing manual EL test circuit.
Once the earth leakage test is initiated, the OTS-EL will measure the time taken for the outlet to open its
contactor or breaking device. In addition, the OTS-EL will also monitor the voltage on the load side of
this breaking device to determine the time that it takes for the back EMF generated by the connected
load to subside to extra low voltage (<50VAC). This represents the true clearing time following an earth
leakage fault.
The magnitude of the current that flows through the earth leakage toroid is determined by the design of
the test circuit installed. It is the responsibility of the installer to ensure that this current is sized to provide
meaningful results when the earth leakage test is conducted by the OTS.
NOTE
The installer is responsible for ensuring that the EL test current is of a
suitable magnitude to provide a meaningful test.
It is recommended that the circuit design is chosen such that the test
current is between 110% and 120% of the trip level of the earth leakage
protection relay (AS/NZS 2081 Appendix E4, AS/NZS 4871.1:2012
Clause 2.6.2.4).

7 SERVICE, MAINTENANCE & DISPOSAL
7.1 Equipment Service
A number of external system based checks should be completed on a regular basis. These ‘routine
inspections’ must be carried out by suitably trained people with knowledge of the Outlet Test System and
the systems into which it is fitted. Routine inspections may take the form of either visual-only checks, or
visual and ‘hands-on’ checks.
7.1.1 Visual Only Inspections
A basic visual inspection focuses on looking at the installation for signs of physical damage, water or
dust ingress and the condition of cables and labels. This type of inspection may involve opening
cabinets to gain access to the OTS-EL and other equipment. This level of inspection may also include
cleaning display windows that have become obscured by dirt.
Observations would typically be:
Check that equipment enclosures, cable trays, conduits, etc. are in good order with no physical
damage.
Check that sealed wall boxes are free from water and dust ingress internally. Door seals are in
good condition.
Check that connected cables are free from cuts, abrasions and obvious signs of damage. Cable
restraints are in good order and correctly fitted.
Check that labels on equipment, wall boxes and cables are present and in good condition
(especially certification labels).
Check that no modifications have been carried out to installed equipment.
7.1.2 Hands-On (Detailed) Inspections
A more detailed inspection would include all of the elements of a visual inspection, plus some checks
that cover the integrity of connections, fixtures and fittings.
In addition to basic visual observations, more detailed integrity checks would involve:
Verify that equipment housings, wall boxes and other mechanical fixtures are secured in place.
This includes terminal box lids, tightness of cable glands, integrity of wall-box mountings, security
of equipment fixing to walls/DIN rails etc.
Verify all electrical connections are secure with no loose screw terminals or DIN rail terminals not
fitted to rails etc.
7.2 Equipment Maintenance
WARNING!
The OTS-EL has no user-serviceable parts.
All repairs must be carried out by Ampcontrol only.
If a fault develops, return the unit to Ampcontrol for repair. It is essential
that no attempt be made to repair the unit as any attempt to
dismantle or repair the unit can seriously compromise the safety of
the unit and voids product warranty.
