POINT

 1.Phase Failure

  When the monitored 3 phase voltage are valid,the output relay is activated;If any of 3 phases fails,the output device switches OFF immediately.Relay LED is OFF,Asymmetry and Phase Sequence error LEDs are ON.

2.Phase Sequence

  When the phase sequence is correct(L1,L2,L3 in clockwise direction) the output relay is activated;however,if the sequence is changed by any reason,the output relay switches OFF immediately.Relay LED is OFF,Phase Sequence error LED is ON.

3.PTC Protection (Only Available in MK-05P,MKC-05P,MKC-06P&MK-06P versions)

  When the coil temperature in motors exceeds Tc,the limit temperature of PTC,the output relay switches off immediately,Relay LED is OFF.This feature is included only in MK-05P,MKC-05P,MK-06P and MKC-06P.See following figure for typical resistance of PTC vs temperature characteristics for three different swiching temperatures(110 ℃,120 ℃,130℃).Normally,PT-110 is used and it can be changed upon request.

4.Voltage Unbalance(Both Unbalance and Delay Adjustable)

  When the phase-phase voltage unbalance is less than the adjusted value by the user,output relay is activated.Ig the unbalance value exceeds the limit value(5%-15%)set by the user,output relay is switched OFF at the end of relay time(0.1...10s) that is also set by the user.Relay LED is OFF,Asymmetry error LED is ON.If the fault disappears within the delay time,the output relay is not switched OFF.

  The voltage unbalance occurs if the phases L1,L2,L3 are loaded unequally.This case is caused by a non-uniform distribution of loads on the lines.The voltage asymmetry causes rise in of the motor temperature and a reduction of the reted motor power.

  Voltage asymmetry limit values are adjusted(5%-15%)by the user.Hysteresis is fixed at 20%

5.Insuffi cient Supply

  L1 is the supply phase of the MK-05 and MK-05P in Pk21 Package while L3 is the supply phase of the MKC0-05 and MKC-05P devices.For MK and MKC devices if supply of voltage falls below 60-65% of rated voltage,output relay switches off without delay and error leds start to blink one after another sequentially.
