6.3 – COMMAND SEQUENCE FOR EMERGENCY OPERATION
Be sure that mains power and emergency power (batteries or UPS) can’t be never simultaneous, and
the exchange between one to the other power is delayed at least by a 2 seconds interval.
1) After a few seconds from mains supply failure, it is necessary to cut out the mains power of the inverter
(terminals L1 L2 L3) and the mains power of the control panel (contactor Ke energized).
2) After about 2 seconds (contactor Ke2 energized), L1 - L2 terminals of the inverter have to be powered
with desired battery voltage; the control panel has to be re-supplied (through an auxiliary inverter), if
necessary, power the NXEM1 board placed inside the inverter with a voltage
≥ 220Vac (<290Vac), and
close the contact on terminal 10 to indicate to the inverter that the emergency operation is required.
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
the car to the desired floor if the parameter P2.10.1 = “Manual” and if voltage and auxiliary power allow
for it, or to the first encountered floor in the most favourable direction if parameter P2.10.1 = “Automatic”,
or “Torque Test” or “Battery Save”.
4) At the end of the emergency operations, inverter have to be un-powered from the auxiliary supply, and
also NXEM1 and the auxiliary inverter for control panel supply has to be un-powered (contactor Ke2 de-
energized).
5) After 2 seconds more, inverter power and control panel power have to be connected again to the mains
(through Ke de-energization) 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.
The following diagram illustrates the sequence of the operations above mentioned:
6.4 – EMERGENCY OPERATION WITHOUT NXEM1 BOARD
As already explained in Paragraph 6.1, the emergency operation can also be executed without the NXEM1
board, using batteries with high voltage (200V or higher) or a 230/400Vac UPS, either single phase or
3-phase.
If the batteries voltage is lower than 200V but equal to or higher than 96V, it is still possible NOT to install the
NXEM1 board, but you have to provide a circuit as the one explained below.
IMPORTANT: The NXEM1 board can only be eliminated in inverters with a rated current up to 27A,
whereas it is always necessary in more powerful inverters.
