7.3 Adding Or Removing Devices; Stop Input - Nice Spin10KCE Instrucciones Y Advertencias Para El Instalador

7.3) Adding or removing devices
Devices can be added or removed at any time on an automation
using SPIN. In particular the inputs STOP and PHOTO can be con-
nected to various types of device as indicated in paragraphs "7.3.1
STOP Input" and 7.3.2 Photocells. The figure shows the wiring dia-
gram for connection of the various devices.

7.3.1) STOP input

STOP is the input that causes immediate shutdown of the move-
ment followed by a brief inversion of the manoeuvre. This input can
be connected to devices with contact types Normally Open (NO),
Normally Closed (NC) or devices with a constant resistance of
8.2KΩ, such as sensitive edges.
The control unit recognises the type of device connected to the
STOP input during the self-learning phase (see paragraph "4.2 –
Learning the door opening and closing positions"); after which a
STOP command is activated whenever a variation with respect to
the learned status is detected.
When set accordingly, more than one device can be connected to
the STOP input, also different from one another:
• Several NO devices can be connected in parallel with no limit to
number.
• Several NC devices can be connected in parallel with no limit to
number.
• Several devices with a constant resistance of 8,2KΩ can be con-
nected "in cascade" with a single terminating resistance of 8,2KΩ
• It is possible to combine two NO and NC contacts, placing them
in parallel, taking care to place a resistance of 8,2KΩ in series with
the NC contact (this also enables the combination of 3 devices:
NO, NC and 8,2KΩ).
!
If the STOP input is used to connect devices with safe-
ty functions, only the devices with a constant resistance
of 8,2KΩ guarantee safety category 3 against faults in
accordance with the standard EN 954-1.
