connect after the 9th delayer, be connected to after the 5th not gate the 8th with the first input end of door;
The B pump startup instruction of B pump control module output after the tenth delayer, be connected to the 8th with the second input end of door;
The 8th is connected to the interlocking termination of pumping command end (ZC) of B pump control module with the output terminal of door;
The 8th is connected the restrictive condition signal end (RO) that the 6th non-permission that is connected to behind the door B pump control module starts pump with the output terminal of door;
The 8th with door output terminal also with the 6th or door the second input end be connected;
Soft key that B pump stops connects and is connected to the 6th or the first input end of door after the tenth pulse oscillator;
The 6th or door output terminal draw the halt instruction of B pump
The restrictive condition signal end (RO) that the permission of B pump control module starts pump has precedence over startup pump command signal end (SO), interlocking termination of pumping command end (ZC) has precedence over and stops pump command signal (SC), stops pump command signal (SC) and has precedence over startup pump command signal end (SO); The B pump halt instruction of being exported by B pump control module or the instruction of B pump startup are sent to electrical control cabinet;
Interlock logic control module comprises:
The normal run signal of A pump
be connected to the 9th with door first input end;
Stand by pump interlock logic drop into soft key be connected to the 9th with the second input end of door and the tenth with the first input end of door;
The normal run signal of B pump
be connected to the tenth with door the second input end;
The 9th with door output terminal be connected to the 7th or door first input end;
The tenth with door output terminal be connected to the 7th or door the second input end;
The 7th or the output terminal of door connect the S pin that is connected to the 3rd trigger after twelve-pulse generator, S represents home position signal;
Stand by pump interlock logic exits soft key and connects after the 13 pulse oscillator with the 8th or the first input end of door and be connected;
A pump during as stand by pump, starts the command signal of stand by pump
connect and be connected to the 8th or the second input end of door after the 14 pulse oscillator;
B pump during as stand by pump, starts the command signal of stand by pump
connect and be connected to the 8th or the 3rd input end of door after the 15 pulse oscillator;
The 8th or the output terminal of door after be connected to the 3rd trigger
pin, R represents that signal resets,
represent the preferential set S of reset R;
The output terminal of the 3rd trigger is the output terminal of interlock logic control module.
