7. Digital Inputs

Three digital inputs are provided: they are active when the relevant terminals are shorted



B2

(terminals 1 - 2)

:

it blocks the operation of the time delayed elements t1I and t2I.



B3

(terminals 1 - 3)

:

it blocks the operation of the time delayed elements t3I.



B4

(terminals 1 - 14)

:

Switching-over from Setting Program 1 (SP1) to Setting Program 2 (SP2)

- Terminals 1

– 14 Open = Setting Program 1 active

- Terminals 1

– 14 Shorted = Setting Program 2 active

The input B4 can also be activated via the serial communication port.
In this case Switching-back from SP2 to SP1 can only be made via serial
port.
Viceversa if the terminals 1

– 14 are shorted, switching-back from SP2 to

SP1 cannot be made via the serial port.

When a function is blocked the pick-up of its time delayed output is inhibited. Programming allows to
have the inhibition either permanent as long as the blocking input is active (tB2=Dis; tB3=Dis) or
automatically removed after the expiry of the set trip time delay of the function involved plus an
additional time 2tBF (tB2=2tBF; tB3=2tBF). By proper interconnection of the blocking inputs and outputs
of different relays it is possible to configurate very efficient arrangements of logic fault discrimination as
well as to feature a safe and quick breaker back-up protection.

8. Test

Besides the normal "WATCHDOG" and "POWERFAIL" functions, a comprehensive program of self-test
and self-diagnostic provides:



Diagnostic and functional test, with checking of program routines and memory's content, run every

time the aux. power is switched-on: the display shows the type of relay and its version number.



Dynamic functional test run during normal operation every 15 min. (relay's operation is suspended

for less than



4ms). If any internal fault is detected, the display shows a fault message, the Led

"PROG/IRF" illuminates and the relay R5 is deenergized.



Complete test activated by the keyboard or via the communication bus either with or without tripping

of the output relays.
