Operation and L.E.D information
• PILOT LED : Green color
• OVER CURRENT LED : Red color
- White : Normal running condition
- Lighting : Over-current trip is peak current sensing
① Power controller make the stopping
② Alarm relay output
③ The color appeared peak current sensing phase.
④ Over current value display on the FND.
- Factor
① At the loads caused by a short between phase
② An earth between the phase and case.
③ An electromagnetic interference and to happen.
• OVER TEMPERATURE : Red color
- White : Normal running condition
- Lighting : A heat sink surface temperature is over the 85℃
① Power controller make the stopping
② Alarm relay output
- Factor
① Cooling fan defect
② Ambient temperature is over the 40℃
Attention!
The units are designed to be used at an ambient temperature less than or equal to 40°C.
Leave a minimum gap of 5cm between two units placed side by side.
Excessive overheating of the controller may lead to incorrect operation of the unit.
This may in turn cause damage to the components.
- Restart : Necessarily examine an over current reason closely and after make “RESET”.
* Running : Over a control output value 0 %, lighting hold
Control output value 0 %, lighting off
* Stop : Lighting off
* Input signal error (4-20mA) : 1 second cycle lighting blink
* P.W value 0 % : 2 second cycle lighting blink
•
PHASE :
3 color L.E.D, Nominal current (per phase) index
of an each load.
RED : R-Phase, Yellow : S-Phase, Green : T-Phase
White : Average nominal current value
•
MODE : Small type push button switch, selectable
load phase for display on the FND.
