• OVERVIEW
The LR…PN is a fully featured, arth Leakage Relay that can either be easily configured using the built-in pre-defined “Profiles” or tailored specifically to suit the
application. The app^ allows the user to define how the unit should operate (see Function diagrams below) as well as configure and set parameters such as the toroid
ratio, relay logic (i.e. energise or de-energise on trip) and define how the Auto-Reclosure mode should operate. Additionally, the option to set a filter cut-off point can
also be defined therefore allowing the unit to ignore signals above a certain frequency.
Utilising NFC technology allows the unit to be used in a “Passive” mode whereby settings can be made in the app and written to the unit without the need for the unit
to be powered. This feature is useful where a panel needs to be shut down and power removed (for safety reasons) before any work or alterations need to be made.
The user also has the ability to read back the configuration of a unit using the app in order to establish/check the settings. Additionally, it is possible to measure (and
display) the actual leakage current present in the system.
An option to recall previous tripping information (accessed via the Logs option in the app) provides the user with historical data allowing the user to establish a pattern
in the tripping occurrence’s and hence make any necessary adjustments.

• INSTALLATION
• B FOR INSTALLATION, ISOLAT TH SUPPLY.
• Connect the unit as shown in the diagram below on the next page (N.B. certain
features may not be required and therefore do not need to be connected).
• nsure the Auxiliary supply voltage to be connected to terminals 5 and 7 matches
the rating of the product.
• A suitably rated fuse should be installed in series with connection to terminal 5
(A1) in order to protect the unit. See Technical specification for further
information.
• Refer to separate data sheet for installation advice regarding the externally
connected toroid.

Earth Leakage Relay – Ty e A (with NFC Technology)
• SETTING
• The unit should be set according to the requirements of the application and the
features required.
Applying Power
• Apply power and the green “supply on” L D ➌ will illuminate.
• Assuming the relays are in their factory default state will operate as follows: The
“positive safety output” (RLY2) relay will energise.
• The positive safety output relay will de-energise if:
a, the fault current level exceeds the set trip level (I∆n) **
b, there is a failure of the connection between the relay and the toroid **
(Note the red “tripped” L D ➍ will flash during this condition)
c, the supply to the unit is removed
** causes the “standard output” relay (RLY1) to energise in response to the fault
condition.
• Prior to the unit tripping, the L D bargraph ➎ will indicate the % of I∆n being
detected (the display is scaled between 25, 50, and 75% of the actual trip level).
After all 3 L D's have illuminated and the unit trips due to an excessive fault
current, the red “tripped” L D ➍ will illuminate.
• After the fault has cleared, the unit will then continue to operate as follows
depending on how initially setup:
a, remain in the latched state
b, automatically reset (if the fault current has cleared and terminals 1 and
2 are linked externally)
c, carry out the auto-reclosing function (if enabled )
Fault simulation (Test mode)
• The unit can be placed into a fault condition by pressing the “Test/Reset” button
➏ on the front of the unit (or by pressing the remote “Test” button - if fitted).
The output relays operate accordingly. Note, if the time delay ( ∆ t) is set, the
“Test” button must be held for this duration before tripping occurs
• Press the same “Test/Reset” button on the front of the unit (or remote “Reset”
button - if fitted) to reset the unit. The output relays revert back to their “non-
tripped” state.
• The unit can also be reset by interrupting the power supply.
• To satisfy regulations, it is recommended that the device be tested periodically to
ensure correct operation.
Troubleshooting
• If the unit fails to operate correctly check that all wiring and connections are
good. Also check that the externally connected toroid meets the requirements of
the product.
Note:
The operating function of this unit is classed as a Ty e A for which tripping is
ensured for residual sinusoidal alternating currents and residual pulsating direct
currents, whether applied suddenly or slowly rising. Additionally, this unit is protected
against nuisance tripping . This unit will also satisfy the requirements for Ty e AC
devices which only need to detect residual alternating currents.
• APP
To utilise the full features, the app must be downloaded and installed on to the device
that will be used to communicate with the unit. This app can be obtained as follows:
•Visit https://play.google.com/store/apps and search for LR-NFC
•Scan the QR code below. This will take you directly to the app
Instructions on using the app to set the additional features can be found in the Help
menu within the app itself.
Note
The unit will need to be power cycled if a new profile is uploaded to the unit.
