4 - CONTROL UNIT

4A - STARTING MODALITY
The control unit has been designed to manage 24V sectional door automations.
To start the system it is necessary to:
1- Connect the power supply, the motors, and the accessories as indicated in the 5C paragraph.
2- Set the dip-switches (paragraph 7A) and the trimmers (paragraph 7B) depending on the wanted functioning and on the
conditions of the system.
3- Perform the standard programming procedure (paragraph 9B) or the professional programming procedure (paragraph 9D) to
recognize the starting point and the end point of the travel and, in case, perform a radiotransmitter programming
procedure (paragraph 9D)
4- Perform the checks reported on paragraph 9C (warning before starting).
If the control unit keeps on having problems after these steps, see paragraph 13 "Signaling led",
to identify possible anomalies, and paragraph 17 "inconvenient and remedy" to try
to eliminate them.
4B - PRESETS
If you perform the standard programming procedure, and there are no modifications on the trimmer regulation and on dip
switches, the control unit will act as follows:
- The safety devices in closing, connected to "PHO1" contact (terminal 16), will intervene only in closing, inverting the motion.
- Pause time before automatic reclosing equal to 120 seconds.
- Pedestrian opening procedure is disabled.
- The slowdowns are set to the final 15% of the travel.
- Operation mode set to STEP by STEP with automatic reclosing

5 - ELECTRIC CONNECTIONS

5A - CABLES SECTION
To access to the control unit it is necessary to open the cover unscrewing the screw (fig.24). Make the cable connection as shown
in the following drawing and insert the cables on the hole using the cable bushing (fig 25).
- The control unit must be powered (by its external fuse box terminal), through a cable which must be at least 3x1.5 mm² wide.
Ifthe distance between the control unit and the grounding system is more than 30m it is necessary to install an electric discharger-
near to the control unit.
- The cables which will be used for the low-tension must be at least 0.25 mm² wide.
- If the length between the control unit and the grounding system is more than 30 m, it is necessary to use screen cables. If
thedistance increases, it is necessary to increase also the section of the wires, to avoid current loss.
- Do not link the cables in underground box, or in inside the pipes.
- Use only RG58 wires to connect external antennas (it can be provided as accessory with included power cables).
5B - NOTE FOR THE CONNECTION
- Every contact which will be connected to the control unit must be free contact.
If there are no connected devices on the terminal 3 (normally closed input "PHO1") or terminal 6 ("STOP"),
the concerning inputs must be bridged.
- If there are connected devices on the terminal 3 (normally closed input "PHO1") or terminal 6 ("STOP"),
the concerning inputs must not be bridged.
If there are more than 1 device connected to the normally closed input "PHO1" (terminal 3) and "STOP" (terminal 6),
they must be connected in series (see paragraphs 14B and 15A).
If there are more than 1 device connected to the normally open input "STR" (terminal 4) they must
be connected in parallel (see paragraphs 14A).
- If an external antenna is connected, the built-in wire in the terminal 10 must be removed.
