CONTROL BOARD FOR BARRIERS 24 Vdc
OPERATING INSTRUCTIONS – INSTALLATION INSTRUCTIONS
1. GENERAL CHARACTERISTICS
Thank to its high powered microprocessor, this control unit for 24 Vdc automatic barriers, offers a wide range of functions and adjustments,
including deceleration and motor control.
A sophisticated electronic control monitors the power circuit at all times and disables the control unit in the event of malfunctions that
could impair efficiency of the electronic clutch.
Main settings and function modes are executed by dip switches, whereas timing, and also power of motor are adjusted through self-
learning at installation. 8 built-in LEDs constantly indicate status of both control unit and gearmotor.
2. TECHNICAL SPECIFICATIONS
Attention: different output values on voltage 24V~ are possible according to the mains voltage. Before starting, always check the
transformer output voltage. It shall not exceed 26V~ both for the 230V~ power supply and 115V~ power supply. Voltage is to be measured
loadless, i.e. when the transformer is supplied with power but disconnected from the board.
3. INSTRUCTIONS
WARNING: To ensure people’s safety, all warnings and instructions in this booklet must be carefully observed. Incorrect installation or
use of the product could cause serious harm to people.
Make sure there is an adequate differential switch upstream of the system as specified by current Standards, and install a thermal breaker
with all-pole switch on the electric mains.
To lay electric cables, use adequate rigid and/or flexible tubes.
Always separate connection cables of low voltage accessories from those operating at 115 / 230 V~.
To prevent any interference whatever, use separate sheaths.
Fitting the buffer batteries
Observe the following instructions to fit the buffer batteries (optional) (see fig.1):
1) Place the battery support, Ref. A, behind the fastening cross piece of the spring
(Ref. B) and fix it with both M5 screws supplied.
2) Position the batteries (optional) and if necessary secure them by means of plastic
clamps (not supplied).
Note: The support has been designed to house 2 batteries having the characteristics
and dimensions specified in the table of paragraph 2.
