APC-TF Series
Operation and L.E.D information
• SCR FAULT : Red color
- White : Normal running condition
- Lighting : A current detection in a stopping condition, sell to SCR short fault.
① Power controller make the stopping
② Alarm relay output
③ The color appeared peak current sensing phase.
④ The load current value display on the FND.
- Factor
① The heat element at short.
② The parallel SCR case which one becomes the breaking among two.
③ The C.T (current transformer) defect
• UNLOAD LED : Red color
- White : Normal running condition
- Blinking : Unload (heat element be cut or at short) sensing
and during the make an analysis
about 10 second.
- Lighting : Unload determination
①
Alarm relay output
②
The color appeared unload sensing phase.
③
The FND value becomes ‘0’.
- Factor
①
The heat element be cut.
②
The heat element at short.
③ The fuse be cut or defect of the SCR.
②
The color appeared sensing of the unbalance load phase.
③
The load current value display on the FND.
- Factor
①
The heating element case which one becomes the breaking among many.
②
The C.T (current transformer) defect
③ The defect one among a parallel SCR.
• UNBALANCE LOAD LED : Red color, Optional function.
- White : Normal running condition
- Blinking : The sensing load current value of an each
line-to-line the declination over the 30%, during the make
an analysis about 10 second.
- Lighting : Unbalance determination
① Alarm relay output
- Restart : Necessarily examine an over current reason closely and after make “RESET”.
