APPENDIX A
Table 1 The LU 7.2 Status formation algorithm
No Lift Unit State State condition
1 Maintenance mode Service key installed or service tool connected
2 Firmware restart Lift Unit microprogram restart
3 Multiple door reversing Miltiple door opening-closing without cabin motion (number of
reversals-address 4 of NVRAM)
4 Machine room penetration Door sensor is open, service key not installed
5 Cabin door opening Inner algorithm
6 Lift cabin movement detected Inner algorithm
7 Cabin door starts opening Inner algorithm
8 Landing door opening Inner algorithm
9 Lift is not powered No voltage at Safety Chain Begin check point
10 “STOP” button clamped
11 Door opened
12 Safety chain open No voltage on Safety Chain End check point while Safety
Chain Begin check point is powered
13 Door is not closed No Door Closing signal after Door Opening signal
14 Safety chain short circuit Simultaneous presence of UP/DOWN signals and Door Closing
/Door Opening signals
15 Dispatcher call Closing "CALL" and "Common/Ground" terminals
16 Unauthorized cabin movement Impulses from OGS while impulses "UP"/"DOWN" are absent
17 Main drive fault Cabin upward/downward motion while no impulses from OGS
18 Door drive fault Continuous signal either of Door Opening or Door Closing
19 Shaft penetration Door Closed without Up/Down signals, as well closing more
than two Door Closed contacts
20 Safety device fault Door locker's contact bounce
21 Out of service Lift is switched to maintenance mode manually, no link with
controller, or critical error from controller received
22 Machine room open MR door sensor is open while service key is installed
23 Voltage at safely chain begin
checkpoint Voltage at Safety Chain Begin check point
24 Movement with safety chain open Either of "UP"/"DOWN" impulses present while safety chain is
open
25 Cabin between floors No "Door opening" signal after "UP"/"DOWN" impulse
completion (status can be cleared only after “UP”/”DOWN”
signals appear)
26 Cabin door sensor malfunction
27 Lack of serial port communication No link with the Lift Controller or the RSA via serial interface
28 Main drive is ON Either of "UP" or "DOWN" signals appear
29 User Bit Signal on XP4 pin 4
