| Question: | The P5/506 bypass panel "Fault" light is ON, but no fault code is shown on the keypad display. What's wrong? |
| Answer: | When this condition occurs, the fault is occurring external to the inverter. Refer to the appropriate C21-, C11, or C01- drawing for the bypass unit in question.(see Table 1 below). When the "K4" relay de-energizes, the fault light will turn on and the motor will not turn. Aside from a P5 inverter fault, one of the following may be the cause:
A motor overload trip that has not yet been reset
A normally closed external safety interlock is open.
