Be sure that mains power and emergency power (batteries) can’t be never simultaneous, and the
exchange between one to the other power is delayed at least by a 2 seconds interval.
Plese follow carefully the indications below,
looking to the figure on the left :
1) After a few seconds from mains supply
failure, it is necessary to cut off the mains
power of the inverter and of the control
panel. On the left figure, the energization
of Ke contactor cuts off the inverter
power and closes the contact between
terminals 6/10, to indicate to the inverter
that the emergency operation is required.
2) After about 2 second from Ke
energization, power again the control
panel and activate the RT relay that has
to remain active for 3 seconds, so that
during this time the terminals L2 – L3 are
supplied with 230Vac voltage. Once RT
relay is de-energized, Ke2 contactor will
energize, powering L1-L2 terminals with
battery voltage. ,.
3) The control panel can now start its
operation like in normal condition. With a
car call or with a reset operation, the
control panel will provide the run and
speed level commands to the inverter: lift
will be bring to the desired floor if
parameter 2.10.1 = 1 (Manual), or to the
first encountered floor in the most
favourable
direction if parameter
2.10.1 = 2 (Automatic)
4) At the end of the emergency operations, inverter has to be un-powered from batteries (contactor Ke2 de-
energized).
5) After 2 seconds more, inverter power and control panel power have to reconnected be to the mains
(through Ke de-energizion) to permit the normal operation restart.
In case of mains power restart during emergency, it is recommended to bring to the end the emergency
cycle.
6.5 – CONSTANT PRESSURE PUSH BUTTON EMERGENCY CONTROL
Regardless of the value set in P2.10.1, for the synchronous motors you can enable an other type of
emergency operation, the CONSTANT PRESSURE PUSH BUTTON EMERGENCY, that switches on
automatically, in emergency mode, if both the UP and DOWN inputs are activated.
To enable this operation, you must supply only the control logic of the drive (NXEM1 board), set the
parameter P2.10.10 “Constant pressure push-button emergency maximum speed” different from 0, activate
the emergency input and, subsequently, the up and down commands, both at the same time.
The inverter will activate the brake command output only, while the control panel must supply the brake
circuit with the proper voltage and, if necessary, make a by-bass on the main motor contactors in the brake
circuit.
These operations enables the brake opening so that the car runs in the direction where the motor is pulled
by the load; the TBM contactor, which makes a short-circuit between the motor windings at stop, doesn’t
energize, so that the car runs at reduced speed.
Moreover, the inverter checks the car speed doesn’t exceed the speed limit set in P2.10.10:
in case the car speed goes over this limit, the inverter makes the brake to close, then makes it to open again
after a few seconds, and goes on this way, with a jogging operation, until the up/down commands stay on,
allowing the car to stop at a floor level without reaching a dangerous speed.
The control panel manufacturer should provide the appropriate audio-visual signalizations, to give warning
the car has reached the floor, while the inverter shows on the display the direction and speed of the car that
is moving (V1.3.1)..
