Explanation of product external form, use terminology and function
▷ PHASE :
3 colors Light Emitting Diode, electric current value
indication of each phase.
RED : R-Phase , Yellow : S-Phase, Green : T-Phase
White : Average nominal current value
▷ S.S :
The time set for soft start, stop, up, down control.
(1-10 Sec)
▷ MODE : Small type push button switch
that select
value of a phase wanting to FND (7-segment).
▷ P.W :
It uses output voltage, current, conduction angle,
phase-shift and power factor to compute the power.
The “PW” potentio meter sets a limit on available
power from the power unit.
The adjustment range is 0 to 100% of the units rating.
▷ O.C :
Over-current trip is peak current sensing. This is important since the instantaneous peak current
can damage a SCR. The “OC” will shutdown the SCR within a half-cycle of AC current, usually
quick enough to protect the SCR.
A local or remote reset pushbutton must be pressed or complete removal of power to the SCR
Power Control is required to reset. Alarm relay output is available for alarming or shutdown.
The adjustment range is 10 to 115% of the unit’s current rating. When set-value less than 10%, do
not excess over-current detection.
▷ PL L.E.D : Operation of PL L.E.D
* Running : Over a control output value 0 %, lighting hold
Control output value 0 %, lighting off
* Stop : Lighting off
* An input signal error (4-20mA) : 1 second cycle blinking
* P.W value 0 % : 2 second cycle blinking
▷ Error status L.E.D
*
OVER-CURRENT : Red color, lighting hold and alarm relay output is available for alarming or shutdown.
* OVER-TEMPERATURE : Red color, lighting hold and alarm relay output is available for alarming or shutdown.
* UNLOAD : Red color, load fault, SCR, FUSE or current transformer defect. During the make an analysis
about 10 second the led blinking and after lighting hold, alarm relay output is available for alarming .
* UNBALANCE
:
Optional function, red color, the load current of an each line-to-line the declination
over the 30%. During the make an analysis about 10 second the led blinking and after lighting hold,
alarm relay output is available for alarming .
* SCR FAULT : A current detection in a stopping condition, sell to SCR short fault.
Lighting hold and alarm relay output is available for alarming or shutdown.
