InsulGard System Installation and Start Up Guideline26 On display ??? (reference signal is likely close to zero). On display continuously 357 (reference signal magnitude is too high).6. Press Enter any time to stop phase measurements. Set Phase Shift will be displayed. Press Enter twice andmanually enter averaged phase shift angle, press Enter again.Note: If using other source of phase reference signal rather than the internal connection to the coupling capacitor onchannel #1, correct obtained phase shift value according to the table below:Phase Reference source Additional Phase ShiftChannel 1 (Coupling Capacitor on Phase A ) 0PT Phase A 0PT Phase B -120PT Phase C -240PT Phase A-B +30PT Phase C-B +907. Press “Esc” to save changes and leave Set mode.8. Return H%/Ref switch into H% position.9. After finishing with phase shift measurement and exiting setting mode in InsulGard go to Unit Settings Tab in thesoftware and type final phase shift angle value in Phase Reference Shift box or go to Communications Tab inthe software and Get Settings from Device to synchronize settings in the monitor and software. Click “UpdateData base with Device settings” when phase shift settings discrepancy will be displayed.10. In InsulGard “Unit Settings” Tab save new configuration by clicking “BackUp Settings” button.Note: Older versions of Insulgard hardware and firmware have deviation from the described aboveprocedure – consult to the Manuals that came with that device or consult to EE PD.2.7 Load Current Channel CalibrationThis procedure describes the process of calibration of the load current channel. After the calibration InsulGard willmeasure running current in percentage of the rated load current. Machine must be running and carry substantialload. Current calibration must be done after rated current already entered into InsulGard settings. Otherwise set therated current, leave set mode and enter set mode again for load calibration.1. Determine the rated load current rating of the machine from the machine nameplate.2. Find the load current the machine is currently running (use ampere meter in Motor Control Center or ask anoperator).3. Divide the value of Step 2 by Step 1 and multiply by 100. This is the percentage of the rated load current themachine is currently pulling.
