•
Any LED state which does not conform with the above probably indicates a malfunction of the SACE PR010/K
unit.
•
The indications given in the above table are with Vaux present, and with the PR010/K not in Self-test, and not in
stand-by mode (see par.5.3).
•
For further details of possible malfunction conditions see para.6.
In the case of the LEDs being designated a significance other than L, S, I and G (standard configuration) it is possible
to use a customised adhesive label (RE0314/001) supplied with the PR010/K unit.

4. Special functions
4.1.
Reset
It is possible to carry out a reset of the PR010/K unit, by pressing the ‘reset’ push-button situated on the front panel of
the unit (see par. 3.1).
This type of reset restarts the Sw of the PR010/K unit (the data memorised in the RAM is conserved).
4.2.
Reset signalling
“Reset signalling” causes the repositioning of the internal relays (K51) to rest conditions (contacts open) following
switching (contacts closed) for protection function (trip).
This reset can be carried out:
-
carrying out a reset (see par.4.1), if the applicable scenario is “PR010/K in Master mode” (see par.1.2).
-
sending a “Trip Reset “ command from the remote supervision system.
-
pressing the RESET push-button on the front of the unit, if the applicable scenario is “PR010/K in Slave mode”
(see par.1.2) and only for Emax series protection units.
4.3.
Self-test function
To carry out the self-test, dip-switch n°1 must be set to ON (see par. 5.3.1) and the reset button pressed.
The self-test switches, in succession, all 8 internal relays, carrying out a functional test on each.
The Tx LED lights with each switching. When the switching is completed the LED flashes at a frequency of 2 Hz.
The self-test takes approx. 10 s, after which the SACE PR010/K unit automatically returns to normal operation.
4.4.
Stand-by function
To select Stand-by mode, dip-switch n°8 must be set to ‘ON’ (see par.5.3.1) and the reset button pressed; in this mode
the internal relays will not be switched.
This function is useful when the protection unit is being tested (for example with PR010/T unit) and the switching of
the relays of the PR010/K unit is not desired.
