The Normal Test switch on the front of the Bypass panel is provided to test or setup the GPD 506/P5 without actually connecting the motor. When in Test mode, the contactor on the input of the inverter is energized bringing three phase power to the inverter but the output contactor is left de-energized. The digital operator can then be used for programming or to issue a run command so that the inverter can be checked for normal operation. Note: A fault message will be displayed on the digital operator when the Test Switch is in the Test position while in Drive mode. This switch should be in the Normal position in Drive mode. Test mode can be used when the Drive/Off/Bypass switch is in either the Off or Bypass position.
