Troubleshooting Guide - Nice E SMART SI 332 AC Instructions And Warnings For Installation And Use

5.7 - Maximum continuous cycle ("thermal protec-
tion" function)
The motor is designed for residential use, in other words, for intermittent service. If
used continuously for a long time, beyond its rating (see "Technical characteristics"),
the system protects the motor against overheating by stopping any further move-
ments until its temperature returns to within the rated limits.
5.8 - Diagnostics and alarm function
On the head of the motor there is a Led that signals the alarm status (with a red
light) and the installation status (with a green light). If it needs to report both at
once, the system always gives priority to alarms. For the meanings of the light sig-
nals, see Table C.
TABLE C – Motor head led signals
GREEN LED Meaning
0 flashes
= assigned address and 2 limit positions programmed.
1 flashes = assigned address and 1 limit position programmed.
= assigned address and no limit positions pro-
2 flashes
grammed.
= network address not yet assigned (the limit switch
3 flashes
status is not shown by the led).
RED LED Meaning
0 flashes
= no error.
= serious error - 1 (motor damaged - contact technical
steady on
service).
1 flash = thermal protection function in progress.
= the last movement was automatically interrupted by
2 flashes
The "Obstacle detection" function.
3 flashes = load too high relative to motor nameplate rating.
4 flashes = serious error - 2.
5 flashes = serious error - 3.
6 flashes = serious error - 4 (control circuit temperature too high).
7 flashes = serious error - 5 (brake malfunction).
8 flashes = serious error - 6 (brake malfunction).
9 flashes = serious error - 7.
10 flashes = serious error - 8.
11 flashes = serious error - 9.
The motor repeats the report message on the status of the installation by performing
some brief movements when a movement is commanded. To understand the signifi-
cance of these movements read Table D.

What to do if...

(troubleshooting guide)

In general, to better identify the problem, refer to Table B (and D), section 5.8.
q Powering an electrical phase, the motor does not move:
After excluding the possibility that thermal protection is active, in which case it is
sufficient to wait for the motor to cool down, make sure the mains voltage corre-
sponds to the values indicated in the "technical data" chapter of this manual by
measuring the voltage between the "common" wire and the electrical phase wire
supplied with current. If the problem is still present, disconnect the power cord
from the motor (fig. 4-i) and connect it again.
q When an Up command is sent, the motor does not start:
This can happen if the awning is near the Upper limit switch ("0"). In this case you
must lower the awning a little bit and give the Raise command again.
q The system operates in the emergency condition with an operator pre-
sent (hold-to-run):
– Check to see if the motor has undergone a significant electrical or mechanical
shock.
– Make sure each part of the motor is still in good condition.
– Delete the UP ("0") and DOWN ("1") limit position and reprogram them.
