TOSHIBA - 42
TX Series 48 - 1250A
SP.5 Relay Configuration (Setpoint Page 5)
(Security Level: 2)
In Setpoint Page 5 the user
can configure the four output
relays as either fail-safe or
non fail-safe and latching or
non-latching.
SP5.1 When a relay has been configured as fail-safe
and power is applied, the relay will be
energized. The relay will then de-energize
when an event occurs or if the power fails.
NOTE: The relays in the TX will not prevent a
start sequence unless they are wired in as
interlocks. If power is lost, the motor power
is also lost.
SP5.2 A relay configured as non-latching will reset
itself when the cause of the trip event is not
continuous. The TRIP (AUX1) relay should
always be programmed for latching, because
this trip should require a visual inspection of
the motor and starter before issuing a
manual reset to release the relay after a trip
has been stored.
