M and S2 from CT goes to L on the unit. Make sure that the three phases coming to the unit come through control fuses 1.0 Amp rating. This will protect the electronics inside from damage due to severe over voltages or phase faults in the system. TRINITY... - Page 8 5. Switch on the three phases supply, the unit will then prompt a power receiving information such as - - - TRINITY- - - -for about 2 to 3 seconds. 6. First of all, user should program the following parameters of the unit: such as Control Mode of operation, Main CT-Ratio, Scroll Seconds, desire PF, Time Delay, On Delay, Off Delay, Bank Stages, Minimum Bank and Autosense.

Faults related to the actual system design: The most common faults are: External Manual Control not implemented properly Here many designers provide a ‘Starter-relay’ configuration for the manual control, and just bring the connection from the relay contact to the contactor. TRINITY [19]... - Page 20 However, the transformer losses will cause the monthly average PF to show up as very poor. The remedy is to connect a small bank directly (independent of the automatic control scheme) for compensating transformer losses. TRINITY [20]...
