2.4.2. Voltage absence AND Logic – Product (L1 x L2 x L3)
With AND logic, the unit terminal block provides the
information on the absence of voltage in the event of a
lack of voltage on all of the phases. Voltage presence (open
contact) on any of the phases causes the circuit to open
and, therefore, the unit indicates a voltage presence.
Conversely, voltage absence is only indicated if it occurs on
the three phases. The terminals to be accessed to obtain the
information, according to this operating logic, are given in
the following figure:
Indication according to AND logic: terminals J1-3 and J1-8
(jumpers between terminals J1-4 - J1-5 and terminals J1-6 - J1-7)

2.4.3. Voltage absence OR Logic – Sum (L1 + L2 + L3)
With OR logic, the unit terminal block provides the
information on the absence of voltage in the event of
a lack of voltage on any of the three phases. Voltage
absence on any of the phases causes the
ekor
.rtk, unit to
indicate an absence of voltage (closed contact), while a
voltage presence is only indicated if MV is present on the
three phases. The terminals to be accessed to obtain the
information, according to this operating logic, are given in
the following figure:
Indication according to OR logic: terminals J1-3 and J1-4
(jumpers between terminals J1-3 - J1-5 - J1-7 and terminals J1-4 - J1-6 - J1-8)
