1.9 Commissioning and risk analysis
1.9.1 Commissioning
Check the earth connection prior to the commissioning of the controller.
If there is no earth connection, the controller must not be commissioned under any circumstances.
1.9.2 Risk analysis
A user of an automatic system is required to carry out a RIE
(Risk Inventory and Evaluation).
With respect to an automatic door, this consists of two things:
1: A list of all (health and safety) risks related to the use of the door.
2: A plan for their resolution .
2 Description of the SDA-04(DCB2)
2.1 Features of the SDA-04(DCB2) controller
2.1.1 Main Features
The main features of the SDA-04(DCB2) controller are:

Usability

High level of safety (active safety equipment)

Automatic restart and calibration after power failure (SDA-04)

Low noise level
2.1.2 Specific features of the Metaflex controllers

The Controller is "auto-adaptive" which means that, for example, in the event of a power failure
or an opening/closing movement, the door will carry out a complete configuration.

When opening the door using the handle, the door will operate fullly automatically after a few
centimetres (adjustable). As a result, even the heaviest doors can be easily opened by hand.

The controller contains a self-monitoring system. If a fault is detected, the controller displays the
nature of the error by displaying an error code on the display. The displayed "service" code can be
used to help identify the cause of the fault. This can help avoid long searches for a fault.

Various types of switches and sensors can be connected to the door so that the door can be
placed into pre-set positions. (open, half open, locked, one-way (only from inside to the outside)

Emergency release in the event of being locked in, for example, using a break glass sensor.

Connectivity to the access control, intrusion alarm and/or fire detection system.

A sluice function is also possible (available from the SDA-04/SDA-04DCB2 that is equipped with
the "advanced" software package). This function ensures that two or more doors that are affected
by this function will not open at the same time. This minimises over-pressure, heat loss and the
movement of dust and bacteria. This sluice function can be disabled by an (optional) switch to
ensure both doors can be opened in an emergency.
