the monitoring devices. The list of statuses generated by the lift unit, their attributes, time intervals are given in
Appendix A.
Machine room penetration control
A door sensor is used to check safety of the MR. When MR door is closed, the contacts of the sensor are closed as
well. On opening door (the contacts are open) the alarm message with the audio is sent to the monitoring devices.
The LU nonvolatile memory (EEPROM)
Each LU has got nonvolatile memory (EEPROM) installed
.
The presence of EEPROM allows overriding of the
firmware standard parameter table in the EEPROM, thus, changing the LU operation.
A service tool should be used
for the matter (see “Service tool operating manual”).
The firmware update
The LU has the feature of the firmware remote updating, of the voice codec and Wi-Fi module updating.
The LU contains one constant and seven variable memory pages, that allow to store up to eight firmware. Remote
reprogramming capabilities allow changing the contents of the seven pages of the chip's memory.
During L
U’s operation, only one of seven memory pages can be active. The bootloader and running firmware are
active.
When the LU is delivered, the first memory page (bootloader) is set active by manufacturer.
The LU firmware is updated using the MProg utility (see the MProg utility user manual). Remote reprogramming is
possible only from a personal computer.
The archive of firmware versions is located on site www.lkds.ru.
After firmware update, it is necessary to perform a function test in accordance with section 3 of the manual.
The manufacturer recommends update the LU firmware periodically.
Managing OUT1 output
The mode of operation of the OUT1 output is stored in EEPROM of a lift unit as per Table 3 of Appendix A. By default:
0-under dispatcher control (excluding for LNGS.465213.270-10 option).
Processing USER1…4 input/output
Inputs USER1..4 of the LU 7.2 can be mapped onto one of the existing states of the LU. By default, USER1..4 inputs
are mapped on
to “USER1..4 State”, respectively. The mapping of USER1..4 inputs is also performed onto those states
whose formation is prohibited. If mapping of several USER inputs is specified for the same state of the LU, then the
resulting state value will be a logical "OR" of USER inputs.
The value “0” prohibits mapping of the USER input onto the state, the values “1..48” allow mapping the USER input
on
to the corresponding state “1..48”, values “101..148” allow inverse mapping of the USER input onto the
corresponding state “1. .48. " The values “210..214” determine the operation mode of the USER1..4 outputs (see
table. Appendix A).
Intercom unit YLED and GLED output setting
The Intercom unit outputs of YLED and GLED are designed to control LED indicators of yellow and green
luminescence in a lift cabin as required by EN 81-28:2018 art.4.1.5 and EN81-70:2018 art. 5.4.2.5. The yellow light
pictogram indicates that the emergency call is registered, and the green pictogram starts lighting at voice negotiation
start (connection is established) (see Fig. 8).
