Line Voltage Checks

  1. During the set up, calibration, and functional checks of this system, monitor the power line voltages similar to what was done during pre-installation site planning checks, refer to Pre-Installation, Power Source Monitoring. In particular, look for variations in the day-to-day line voltage that do not meet equipment specifications. Look for any voltage disturbances that might correlate to system malfunctions or component failures. (One recommended analyzer that is designed for unattended monitoring is the Dranetz Model 606-3 [3-channel] with 101 frequency option, or the Dranetz Model 626 with the 6003 3-phase AC monitor option.) Ensure that the power meets site planning requirements. Refer to Pre-Installation.
