Logic sequence 4)
The time sequence diagram of the advanced door-open module shows the relations between
relays and signals, the high electric level indicates the signal is valid.
Fig 3-33 Time sequence diagram
When apply power, according to the wiring diagram, the relay KM1 will operate, and the
relevant contact will activate; when elevator run and detect out the up re-leveling signal 1(FL1)
is valid, the relay KM2 will operate and the relevant contact shall activate; when detect out the
down re-leveling signal 2（FL2）is valid, the relay KM3 will operate and the relevant co
ntact
activate, accordingly will make the door zone signal input SX1(X2) valid; when the system
detect out this signal, the advanced door-open output relay Y3 (SY) will output, the KM4 will be
valid together with the KM2 and KM3, and the relevant contacts will be activated, the system
will detect out that the advanced door-open signal SX2(X8) valid, at the same time the lock
will operate to short
the door-lock and to realize the advanced door-open function. After the
advanced opening, the advanced opening relay will be break, the KM4 will stop operating, the
advanced opening signal input signal will be invalid and the lock break; when the up re-leveling
signal 1(FL1) is invalid, the KM2 will stop operation and the door area input signal is invalid;
when the down re-leveling signal 2 (FL2)
is invalid, the relay KM3 stop operation, then the KM1
will operate and the relevant contacts will activate.
Re-leveling door area sensor and installation method.5)
The advanced door-open/ re-leveling function need to add leveling sensor, up leveling sensor,
up re-leveling door area sensor FL1, down re-leveling door area sensor FL2, and down leveling
sensor. Please install it by sequence or the d
irections will be reversal.
In the condition of on-site application, if there is only one door area sensor signal, user needs
to short the FL1 and FL2, and the up/down re-leveling signals are taken for the same one.
