3.3.7. Accessories power supply terminals (+24VDC)
Control unit is equipped with accessories power supply outputs 24VDC max. load 0,5A. The outputs have
three equal screw terminals with mass potential (0V) and two equal terminals with the +24V potential.
3.3.8 Terminals for TX, PHOTO OP, PHOTO CL and PHOTO OP/CL photocells connection
If applied photocells are powered by 24V, with separate receiver and transmitter supply, then the
following connections are applicable: "+" of transmitter and receiver power supply to the output of accessories
24 VDC, "- " transmitter power supply to the TX terminal (output OC type), and "-" of receiver power
supply to mass as standard. If photocells have a shared power supply for the transmitter and the receiver, then
their "- " of power supply to the TX output. Such a way of connecting, allows to use PHOTO-TEST function which
checks photocells operation before every move of the gate and blocks the move in case of detecting the
breakdown. PHOTO-TEST function improves the security level significantly. In order to engage PHOTO-TEST
function, see p. 5.2.1. PHOTO OP input is dedicated to the photocell installed parallel to the line of the gate
movement, it secures the zone of the stroke of the gate. PHOTO CL input is dedicated to the outside photocell
(outside premises) installed parallel to the edge of entrance, PHOTO OP/CL input is dedicated to the inside
photocell (on the area of premises), installed parallel to the edge of entrance. Unused sockets of photocells
should be connected with TX terminal (all sockets of photocells are connected with wire factory-made (bridged).
3.3.9. Manual steering INPUT STOP and OPEN (A, B, C) terminals
Momentary button (monostable) of NC type should be connected to INPUT STOP terminals. If the
button is not used, the terminals should be clenched with a wire. Momentary buttons of NO type can be
connected to OPEN A and OPEN B terminals. These momentary buttons will control the work of the control unit
according to the adjusted mode (see table of modes of the control unit). It is possible to connect the momentary
button of NO type to the OPEN C terminal. This button will activate additional channel output OUTC. All unused
inputs of NO type should be left not connected. Activating the button of the manual steering consists in its
momentary pressing. OPEN A, B and C inputs are functional equivalent of radio receiver channels (channel A, B
and C).
3.3.10. EasyRX radio receiver connector
This connector enables the control of servomotor with the help of DTM433MHz series remote controls
by the additional board of the radio receiver. The receiver communicates with the control unit through the local
data bus which makes it impossible to connect other radio receivers to the connector. The installation and the
programming are described in p. 6 of this manual.
4. Description of control unit operations
Control unit is immediately ready to work after switching on the power supply. After pressing any button
of the programmed remote control or releasing the controlling input, appropriate function of the control unit is
performed. In the operation mode, the current state is signalled with the help of the signal output and LED
diodes. In sleeping mode all red diodes should shine, and green ones remain turned off. Immediately after
switching on the power supply the first move is opening.
4.1 . Gate leaves synchronization
When one servomotor encounters an obstacle, which prevents its further movement it does not cause
the stop of the second one. In such case there is a possibility of gate leaves desynchronizing which can be
important when the closing order of the leaves is relevant. It is necessary to synchronize such gate again. It should
be performed as follows:
engage OPENING movement
wait for full opening of both gate leaves ( it May be necessary to engage CLOSING Direction and then OPENING).
5. Programming of EASY B232 control unit
EASY B232 control unit is programmed to needs of the given installation using the LEARN button with
the LEARN diode, DIP-SWITCH microswitches with the division into two sections FUNCTION and MODE and
three rotational potentiometers.
In order to conduct the process of the programming efficiently it is necessary to keep the following order :
- analyse tables with individual operational modes and choose appropriate with the help of DIP-SWITCH MODE
part
- turn on or turn off chosen functions off in FUNCTION section
