#HAPTER CGCM Unit Configuration
•
Rotating Diode Fault Delay - Establishes the time duration that the ripple
current must be at or above the fault level before the CGCM unit
annunciates a rotating diode fault. Tag
DiodeMonitorTimeDelay in the
configuration table stores this value, expressed in seconds.
•
Excitation Select – Selects the excitation power source. This parameter is
stored in the Boolean tag
PMG_Shunt_Select in the Configuration table.
In this tag, 0 = PMG, 1 = Shunt. Select PMG to enable the loss of PMG
sensing. Select Shunt for obtaining excitation power from the generator’s
terminals and for systems using series boost.
•
PMG Phase Select – Establishes whether the excitation power source to
the CGCM unit is single or 3-phase, to assure correct operation of the loss
of PMG sensing function. This parameter is stored in the Boolean tag
PMG_1Ph_3Ph_Select in the Configuration table. In this tag, 0 = single
phase, 1 = 3-phase.
