724MPS - MICROPROCESSOR CONTROL UNIT FOR 24 Vdc SLIDING GATES WITH ENCODER

4. GENERAL CHARACTERISTICS

Thank to its high powered microprocessor, this control unit for 24 Vdc sliding gates 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. 3 built-in LEDs constantly indicate status of both control unit and gearmotor. The control unit is designed for installation in a container on the gearmotor itself or in the watertight container for outdoor use, which is also designed to house 2 optional batteries and a torodial transformer, with the characteristics in the table below.

6. 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 laws, and install a thermal breaker with all-pole switch on the electrical mains. To lay electrical cables, use adequate rigid and/or flexible tubes. Always separate connection cables of low voltage accessories from those operating at 230 V~. To prevent any interference whatever, use separate sheaths. In the version with control unit installed on the gearmotor, some connections and units described in these instructions (motor, transformer, encoder, etc) are factory prewired.

In the version with control unit housed in the watertight outdoor use container, maximum length of connection cables between control unit and motor/encoder must not exceed 3 m., using 2x2.5mm² cables for the motor and 3x0.5mm² cables for the encoder.

Procedure (referring to fig. 13) for securing components in the watertight container:

1) Secure the support of the toroidal transformer in position A by fitting

three Ø3.9x6.5 self-tapping screws (supplied) in the guides of the watertight container.

N.B.

: the support is sized to house a transformer with characteristics and dimensions specified in the table in paragraph 5.

2) Secure the transformer on the support with 2 clamps (supplied).

3)If using floating batteries, secure the relevant support in position B by fitting four Ø3.9x6.5 self-tapping screws (supplied) in the crossover holes of the guides of the watertight container.

N.B.

: the support is sized to house two batteries (not supplied) with characteristics and dimensions specified in the table in paragraph 5.

4) Position the batteries on the support.

5) Secure the control unit in position C by fitting four Ø3.9x6.5 self-

tapping screws (supplied) in the guides of the watertight container.

Fig. 13

Procedure for securing the encoder on the gearmotor (fig. 14) :

1) Using the four M4x10 screws C (supplied), secure card B on cover A, locating the spacers D between cover and card.

2) Using the M4x30 screw F (supplied), secure encoder E directly on the thread on the rotor of the gearmotor.

3) Wire up terminal board G as described below.

7. CONNECTIONS

7.1 TERMINAL BOARD M1

22V~ Power supply

Terminals “1-2”. This is the input to which the secondary winding of the transformer, powered at 22 V~ 50Hz, should be connected. When power is supplied by the transformer, this is signalled by the POWER LED lighting up.

Batteries

Terminals “3-4”. The control unit is designed to operate with two floating batteries (optional item) with minimum characteristics as indicated on the table in paragraph 5. When powered, the control unit keeps the batteries charged. The batteries begin to operate when the transformer no longer supplies power.

N.B.

: power supplied by batteries should be considered an emergency situation – the minimum number of gate operations is about 10/15. In any event, the number of possible operations depends on the quality of the batteries, structure of gate, and time elapsing since mains power failed, etc, etc..

N.B.

: observe the power polarity of the batteries

Accessories

Terminals “5-6”. Output for powering external accessories (24 Vdc).

N.B.

: maximum load of accessories is 500 mA.

7.2 TERMINAL BOARD M2

Gearmotor

Terminals “7-8”. Connect the motor to the power supply of 24Vdc 70W max.

Flashlight

Terminals “9-10”. Use a flashlight with fixed light operating voltage of 24Vdc 15W max. We advise you to connect it before programming, as it indicates programming stages. On opening, it pre-flashes steadily for 0.5 seconds, and for 1.5 seconds at closing. If the automatic logic is on, when the gate reaches the opening gate stop, the flashlight stays on for 5 sec to inform the user it will re-close automatically. When the gate is open, the flashlight is off, and only flashes when the safety devices are in use. If the devices are in use for a long time, flashing only lasts 10 sec.

7.3 TERMINAL BOARD M3

Encoder

Terminals “11-12-13”. Use the encoder supplied with the control unit. Connect the return signal from encoder terminal “11” to terminal “11”, connect encoder terminals “12-13” to terminals “12-13”.

NB.

: the control unit will not operate without an encoder.

NB.

: observe the encoder's cable terminals.

Open-A

Terminals “14-18”. Any device (e.g. push-button, remote control, etc.) can be connected to this circuit. By closing a contact, the circuit generates a pulse for total opening and/or closing of the gate. Its operating mode is set by dip-switch 3 – see paragraph 9.

N.B.

: a OPEN-A pulse during the pedestrian stage always has priority over that stage

N.B.

: to install several pulse generators, connect the contacts in parallel.

Open-B (For pedestrian use)

Terminals “15-18”. Any device (e.g. push-button, remote control, etc.) can be connected to this circuit.
