11.1 Operating state display
Operating states are indicated on the "H401" 7-segment display or the "H1" digital display of the
control unit.
The SIDOOR ATD420W / ATD430W control units additionally enable retrieval of status
information via the parameter r2100 ("Status code") or, as of rmware version V1.12, via the
technology status word TZW3, TZW4 and TZW5 (see section TZW3, TZW4, TZW5 - Technology
status words - 3, 4, 5 (Page 327)).
The following operating states are shown:
Display Meaning
Info
O
1)
Light barrier / pressure-sensitive edge interrupted
6 Motor obstructed in the closing direction
c Obstruction while opening
d Door remains stationary during initialization run (no OPEN or CLOSE signal present, or door has reached end
position)
H Determination of parameters (learn run)
o Function OK
u Door is closed
Fault
1 RAM, EEPROM or CPU error (system error)
2 Braking chopper defective or overheated.
3 Error in the second shutdown route
4 Motor protection, maximum opening or closing time of 65 s has been exceeded
5 Motor undened – no learn run carried out with this motor type
(If a dierent motor version is used, the learn run must be repeated at power on as described in these Operating
Instructions. See Table 5-28 Starting a learn run when the line voltage is applied (Page 178))
7 Error in pulse generator
8 OSSD (ESPE or pressure sensitive edge) - function test failed
9 Motor overcurrent
E Motor overvoltage
F Motor undervoltage
n Power stage error
L Current measurement error
t Belt torn
U Max. mass to be moved:
Alarm
4 Automatic extension of the hold-open time (motor protection) or the door is blocked for more than 5 seconds
outside the obstruction detection area (p3856, p3857, p3873, p3874) and the motor current was reduced to
the nominal motor current.
