Samwha DSP DSP-VIP-PL - Voltage-Based Trip Indications

Locked Rotor
trip caused by locked rotor current in
phase L2 during motor staet
Shock/Stall
trip caused by shocking current in
phase L2 during working
Short
trip caused by short circuit current in
phase L2
Over Temp
trip caused by over temperature/3
LED of L1,L2,L3 is flickering together
Trip indication caused by Voltage only:
*Target:OP,UP,vUb
*Output feature:OV/UV(27-28-30) trip/Independent from Main trip:VIP takes normal protection job
*Indication:Basically a trip caused by voltage is reset automaticaliy if trip cause is clear , so when trip
is happened, LED indication for both voltage and trip cause is shown together as below while
normal circulation for each factor is turned on,then move forward to next indication factor.

Cause
Over
voltage
(OP)
trip caused by over voltage with value
of 250V in phase L1-L2 during
running
Under
voltage
(UP)
trip caused by under voltage with
value of 190V in phase L1-L2 during
running
Voltage
unbalanc
e(vUb)
trip caused by voltage unbalance with
which the deviation between max and
min is 190V
Zero
Voltage
during
running
trip caused by line voltage zero during
running.
