The Sematic Drive System

controller has the ability to diagnose and record a number of defects; such diagnostics is very helpful to the
maintenance personnel in order to locate possible operational problems.
When any monitored error occurs, the Door Controller display will signal it and the error code will show.
The following table illustrates the type of signalling and the relevant alarm detected by the Door Controller:
ALARMS TABLE
Code on
display
Viewed error
Error description
Action undertaken by Door controller
01
No MLC Signal
Main lift controller is disconnected or
has failed (Note 1)
Auto reset when proper condition is restored.
02
Over current protection
Motor over current due to door mechani-
cal strain (Note 2)
Auto reset after:
ca. 5 seconds after the first and second trials (fast
alarm)
ca. 5 minutes (B105AANX motor type) and 3 mi-
nutes (B105AALX motor type) at the third trial
03
Reversing system fault
The main lift controller does not send
the reopening command after the Door
Controller has signalled an obstacle
(Note 3)
Door drive keeps on closing at low speed
04
Power-on motor inverted Inverted motor connection or inverted
Encoder channels. Door performs a jerk
and then stops (Note 4)
Auto reset, after about 10 seconds, when normal
operating conditions are restored; after 5 trials
the system stops.
05
Encoder jerk
Interruption of the motor’s Encoder ca-
bles, or interruption of the motor cables
after system’s start up or the connecting
plug to the Encoder motor is inverted
Auto reset after 5 seconds; after 5 occurrences
within 5 minutes the system stops
06
Motor thermal protection Motor over-heating (with motors where
internal PTC sensor is present)
Auto reset when normal operating conditions are
restored.
07
Motor jerk
Interruption of the motor cables
Auto reset after 5 seconds; after 5 occurrences
within 5 minutes the system stops
08
Over-voltage
Over-voltage in the power supply
Door controller switches to low speed, signals the
error, and performs an auto-reset; after 5 occur-
rences within 5 minutes the system stops
09
PWM-Trip
Impulse over-current
Auto reset when proper condition is restored;
after 5 occurrences within 5 minutes the system
stops.
10
Internal fault
Generic alarm due to an internal mal-
function of the Door Controller
Auto reset when proper condition is restored.
11
Power supply protection
Internal switching power supply over
current, due to mechanical strain
Auto reset when proper condition is restored;
after 5 occurrences within 5 minutes the system
stops.
12
Mechanical block
Door movement blocked during the
normal opening phase (note2)
After max 7 sec. the system reduce the opening
torque
Notes:
1.
This alarm can only occur if the Main Lift Controller Test has been set either to “WHEN Moving” or “Parking” and the “Main
Lift Controller Input Alarm” parameter has been set to “ON” .
2.
This alarm indicates an excessive strain in the operator’s functioning; it is advisable to check that the system has no friction
whatsoever, especially during the opening phase. The alarm is just recorded in the alarm list but not displayed on the door drive
front panel.
3.
This alarm can only occur if the REVERSING SYSTEM parameter has been set to “EXTERNAL”.
4.
If both connections (motor and Encoder signals) are inverted, the door opens when a closing signal is received and closes with an
opening signal. The Door Operator is pre-wired and tested by the manufacturer; so special attention must be taken when replacing
motor and/or cables.
