Applying Power. Operation
• The unit supplied with factory default settings. Also check that the externally
connected toroid meets the requirements the product.
. After all LED's have illuminated and the unit trips due an
excessive fault current, the red “tripped” LED will illuminate.
• The unit can also reset interrupting the power supply.
The output relays revert their “non-tripped” state.
• should set according the requirements the application and the features required. Additionally,
this unit protected against nuisance tripping This unit will also satisfy the requirements for Type devices
which only need detect residual alternating currents.com Page 13

Troubleshooting.
Note:
The operating function this unit classed Type for which tripping ensured for residual sinusoidal
alternating currents and residual pulsating direct currents, whether applied suddenly slowly rising.
• After the fault has cleared, the unit will then continue operate follows depending how initially setup:
a, remain the latched state
b, automatically reset (if the fault current has cleared and auto-reset mode has been enabled)
c, carry out the auto-reclosing function (if enabled)

• Apply power and the green “supply on” LED will illuminate.
• Assuming the relays are their factory default state will operate follows: The “positive safety output” (RLY2)
relay will energise.
• The unit can placed into fault condition pressing the “Test/Reset” button the front the unit (or by
pressing the remote “Test” button fitted).tele-online.
• Prior the unit tripping, the LED bargraph will indicate the I∆n being detected (the display scaled
between 25, 50, and 75% the actual trip level). Note, the time delay (∆t) is
set, the “Test” button must held for this duration before tripping occurs.
• The positive safety output relay will de-energise if:
a, the fault current level exceeds the set trip level (I∆n) **
b, there failure the connection between the relay and the toroid (Note the red “tripped” LED will
flash during this condition)
c, the supply the unit removed
** causes the “standard output” relay (RLY1) energise response the fault condition.
• satisfy regulations, recommended that the device tested periodically ensure correct operation.
• Press the same “Test/Reset” button the front the unit (or remote “Reset” button fitted) reset the unit. The output relays operate accordingly.
• the unit fails operate correctly check that all wiring and connections are good
