PRODUCT DESCRIPTION AND INTENDED USE
DPRO924 is a control unit to be used to automate sectional balanced doors. It can control motors with an encoder or Hall effect position control system or using
electromechanical limit switches.
DPRO924 is particularly suitable to be connected to Sumo motors and Opera System devices.
Available accessories: receivers with “SM” (SMXI, OXI, etc.) coupling.
CAUTION! – All uses other than the intended use described and use in environmental conditions other than those described in this manual
should be considered improper and forbidden!

INSTALLATION
2.1 - Pre-installation checks
Before proceeding with installation, check the condition of the product components, suitability of the selected model and conditions of the intended installation
environment:
• Check that all conditions of use fall within the “application limits” of the product (paragraph 2.2) and the value limits shown in the “Product technical character-
istics” (chap. 9).
• Check that the installation location is compatible with the overall dimensions of the product (
Fig. 1
).
• Check that the surface chosen for installing the product is solid and can ensure stable attachment.
• Make sure that the installation area is not subject to flooding; if necessary, the product may be installed, appropriately raised above ground level.
• Check that the space around the product allows safe and easy access.
• Check that all electrical cables to be used belong to the type listed in Table 1.
• Check that the automation has mechanical stops in both the opening and closing phases.
2.2 - Product application limits
The product can be used only on sectional balanced doors with Nice motors of the Sumo family.
CAUTION! – The control unit described in this instruction manual cannot be used in areas at risk of explosion.
2.3 - Typical system
Fig. 2
provides an example of an automation system, produced using Nice components:
1
Gearmotor
6
Spiral cable
2
Transmitter
7
Flashing light
3
Sensitive edge
8
Photocell
4
Junction box
9
Digital keyboard - Transponder reader - Key selector switch - Push button panel
5
Control unit
These parts are positioned according to a typical standard layout. With reference to
Fig. 2
, locate the approximate position for installation of each component
envisaged in the system.
Important
– Before installation, prepare the necessary electrical cables as per fig. 2 and Table 1.
Caution!
– When laying the ducting for routing the electrical cables and for the cable entry point into the control unit housing, be aware that due to possible
deposits of water in the junction wells, the connection ducts might create condensate in the control unit, with consequent damage to the electronic circuits.
2.4 - Installation of the control unit
01.
Open the control unit box:
unscrew the screws as shown in
Fig. 3-A
/
Fig. 3-B
;
02.
Prepare the holes for routing the electrical cables for the accessories providing control and/or signalling functions. For this purpose, we recommend using
a special tool (e.g. hole cutter) on the marked positions at the bottom of the box, also to ensure maintaining the level of IP protection. If necessary, you can
use the lateral cable entry points, but only by using suitable ducting connections;
03.
Secure the box
: it can be fixed in three ways:
a) directly onto the wall using the screws from inside the box (
Fig. 4-A
);
b) using the standard supports supplied (
Fig. 4-B
);
c) if the cable duct for routing the electrical cables is on the outside and you need to fix the box at a maximum distance of 2 cm away from the wall to allow
the cables to be routed behind the control unit. NDA100 consists of 4 spacers and a protective cover for introducing the cables inside the control unit box.
To install the unit using the (optional) accessory, see
Fig. 4-C
.
04.
At this point, you can make all the electrical connections: see Chapter 3.
To install the other devices used on the automated system, refer to the respective instruction manuals.

•
As regards the risks of crushing and impact, the doors are protected by means of one of these three methods:
1
- For operation with “hold-to-run command” (man present): as specified in EN 12453, point 5.1.1.4. In this case the command button
must be placed in view of the automation and if it is accessible to the public, the command button must not be available to them, e.g.
use only with a key switch.
2
- For “Semi-automatic” operation: through the use of an active sensitive edge for limiting the forces as specified in EN 12453, paragraphs
5.1.1.5 and 5.1.3.
3
- For “automatic” operation: through the use of an active sensitive edge for limiting the forces as specified in EN 12453, paragraphs 5.1.1.5
and 5.1.3; in this case, at least one pair of photocells must be installed as shown in
Fig. 2
.
