Fig.8 Yellow and Green pictograms
The yellow icon lights up when call button is pressed. The green
pictogram lights up when the dispatcher’s
communication connection with a lift cabin is switched to on.
The outputs YLED, GLED are of 5V voltage with a current limit of 25 mA.
Voice communication tract self test
The function of automatic test of the voice communication tract has been implemented. The test is performed
permanently. Had the link with the Intercom unit had broken,
the message “Voice communication tract unavailable”
should be generated by monitoring software.
To allow testing at address 11 of EEPROM, the value of minimum permissible quality of the route should be set, in
percents (the range is from 0 to 99). The default value is 0. When set to 255, the automatic test is disabled.
Statuses “No mains power” and “Safety circuit AC voltage”
The status
“No mains power” is formed when the LU switches to backup power from the battery when the mains
voltage of 230V is out.
The status "Safety circuit AC voltage" is generated when there is an alternate component at checkpoint 110V (SCB) of
the RSA. This state is formed only on LB 7.2
– Р.
Passenger in a cabin control
For the LU of -R option, an algorithm for determining the presence of a passenger in a lift cabin is implemented. For
LUs communicating with a lift controller via a serial bus, the status mentioned is used to indicate the presence of a
person in a lift cabin (if such information is given out by a controller).
The function is activated by writing the value “1”
at the address 92 EEPROM of the LU.
Relay lift call circuit testing
The LU of
–R option has got a function of monitoring the health of the call chain. To implement the call circuit test
function on the relay lifts, it is necessary to connect the LU checkpoint
“Out of Service” to the lift circuit and enable the
call circuit health monitoring function by writing the value “99” at address 12 of EEPROM of the LU.
Audio in a cabin
The LU has an audible warning function in a lift cabin. Sounds in a lift cabin can be implemented in the form of: a
sound signal, the phrase “The call has been registered. Wait for an answer”, a floor arrival message, as well as playing
back a soundtrack.
The function becomes available on setting the values “0 ... 15” at the address 14 of EEPROM of
the LU. The table of possible values is given in Appendix D.
Audio content from SD card
ATTENTION!
If a link between the IU and the LU or the control center/server is broken, the
pictograms are alternately lit with a period of 2 seconds.
