4.6.6.1.ZERO CALIBRATION-GENERATOR
4.6.6.1.1.Energize the utility supply to power up the controller and de-
energize the generator supply. NOTE: The phases being
calibrated for zero must have a true zero reference to ground to
allow proper calibration therefore the TSC 80e sensing inputs for
the generator must be temporarily grounded to provide this true
zero reference.
4.6.6.1.2.To gain access to the Voltage Calibration menu, follow the
Programming instructions for User Password & Submenu per
sections 5.1 & 5.2. Once the Voltage Calibration sub-menu is
accessed, press the ENTER key. Scroll to the display the GEN
Phase A ZERO. To calibrate the Gen phase A ZERO press the
ENTER key again.
4.6.6.1.3.Use the UP or DOWN arrow pushbuttons to adjust the
correction factor number while observing the displayed voltage
level. Adjust the correction factor number to obtain 0VAC on the
display.
4.6.6.1.4.With zero voltage displayed, press the ENTER pushbutton to
accept the correction factor number.
4.6.6.1.5. To zero calibrate the other generator phases, press the
ENTER pushbutton to select the desired phase, then press
ENTER again to adjust its correction factor and repeat the
procedures as outlined above.
4.6.6.2.ZERO CALIBRATION-UTILITY
4.6.6.2.1.Energize the generator supply to power up the controller and
de-energize the utility supply. NOTE: The phases being
calibrated for zero must have a true zero reference to ground to
allow proper calibration therefore the TSC 80e sensing inputs for
the utility must be temporarily grounded to provide this true zero
reference.
