SCR Temperature Fault (Hex code =0x0400)

The measured SCR Temperature has exceeded either the Alarm or Fault limit. Probably due to

insufficient SCR plate cooling.

Lock Out Fault (Hex code =0x0800)

If any (or a combination of) the Faults listed below occurs more than 3 times (reg. 40262) within 30

minutes (reg. 40263), a “Lock Out Fault” occurs:

• Inverter Temperature trip

• SCR Temperature trip

• Motor Current High trip

• Inverter Error Signal Active trip

• Rotor May Be Locked trip

• Motor Back emf trip

*Instantaneous lock outs:

•Discharge Pressure

•3 Phase Over-Current

Winding Temperature Fault (Hex code =0x1000)

The measured motor winding temperature has exceeded 155ºC.

Superheat Fault (Hex code =0x2000)

The Fault limit is based on the suction pressure and temperature values. There is no time delay on this

fault or alarm. The difference between the fault limit and alarm limit is the dead band for the control.

Reserved (Hex code =0x4000)

Reserved (Hex code =0x8000)
