! Unit control states
– electronics supplied with voltage
– self-test running
– initialisation running
– Uzk control is disabled
– relay „ready for use“ is OFF (relay is fallen off - BUC is not ready)
– software/hardware initialisation completed
– Uzk control is disabled
– main contactor is not enabled (internal contact between X1:6 and X1:7 open, see terminal dia-
gram BUC)
– charge circuit can be activated (power on - see terminal diagram BUC63), the intermediate circuit
can be charged
– relay „ready for use“ is OFF (relay is fallen off - BUC is not ready)
– intermediate circuit voltage has reached the value set in P600, no flow of charge current
– Uzk controller is disabled
– main contactor is enabled (internal contact between X1:6 and X1:7 closed, see terminal diagram
BUC)
– main contactor is activated
– timer with set main contactor switching time (P601 MC switching time) is started
– relay "ready for use" is OFF (relay is fallen off - BUC is not ready)
– intermediate circuit voltage has reached set value P600
– Uzk control is disabled
– main contactor switched, the main contactor switching time runs up (P601 MC switching time)
– mains voltage lays on the BUC power unit, the controller is synchronous with the mains
– signal "ready for pulse enable" is enabled (see X26:22, terminal diagram V-controller
– relay "ready for use" is OFF (relay is fallen off - BUC is not ready)
– pulses are enabled (see X26:14, terminal diagram V-controller)
– Uzk control is enabled
– timer with set pre-control time (P602) is started and the intermediate circuit voltage is increased
to set Uzk nominal value (P087)
– relay "ready for use" is OFF (relay is fallen off - BUC is not ready)
– Uzk control is enabled
– intermediate circuit voltage has reached Uzk nominal value (P087)
– relay "ready for use" is ON (relay is closed - BUC is ready)
