THREE-PHASE
THREE-PHASE FOR AUTOMATIONS WITH HEAVY SLIDING
GATES - DIGITAL PROGRAMMING
In case of failure of operation:
- Verify that the power supply to the electronic unit is 230V ±10%
- Verify that the power supply to the Electric motor is 230V ±10%
- For distances over 50 meters increase the wire section.
- Verify the fuses
- Verify that the Photocells are in closed contact setting
- Verify all the closed contacts NC: Stop, Safety Switch and Safety Edges
- Verify that there is no voltage drop between control panel and electric motor
- Verify to have connected the earth ground terminals 19 and 23
- Verify that the Motor and its terminal board are connected to work at 230V
- Verify that low speed and operator torque settings are adapted to the weight of the gate.
Description: The electronic control panel Elpro 220 is an electronic unit with microprocessor for motors up to 3,0 HP (2,2KW) three-phase, installed on big sliding gates.
Power supply is of 230V 50Hz±10% single-phase. Elpro 220 controls three-phase motors 220V delta connection, or single-phase motors without condenser. A display allows
programming of the main function as required and real time visualising: braking with motor slowdown, motor gradual starting, gate limit travel autolearning, torque control
on lower speed setting on braking and starting phases, operator torque control adjustment. It is built in full compliance with BT 93/68/CE Low Voltage and EMC 93/68/CE
Electro-Magnetic Compatibility Regulations. Fitting operations are recommended to be carried out by a qualified technician in conformity to the existing safety standards.
The manufacturing company declines any responsability for incorrect handling and applications; also, it reserves the right to change these instructions or update the control
panel any time. Failure to observe the installation instructions may cause serious damages to properties and persons.
IMPORTANT:
- The control unit is to be fitted in a sheltered place inside a suitable enclosure
- Fit the mains to the control panel with a 0.03A high performance magnetic-thermal circuit breaker
- Verify that the power supply to the electronic control panel is 230V ±10% 50Hz
- For power supply to the electric motor 230V ±10% 50Hz use 2.5 mm2section wires to 50 m distances and set the motor terminal board for 230V power supply
-
Power supply, Flashing lamp use cables with 1,5 mm2section wires up to 50m of distance; for limit switches and accessories use cables with 1mm2section wires
- If photocells are not used bridge terminals 1 and 2, 25 and 26, 27 and 28 with 26
- If no key or button-operated switch is used bridge terminals 3 and 6
- To use shielded cables for the motor connection and to earth system by using terminal 19.
ATTENTION:
- Once power to the control panel is interrupted, wait until the condensers are discharged: D2 led must go off
- The control panel is factory pre-set on “deadman control” mode
- For the 24V direct current low voltage connections, respect strictly + and - symbols
- The system can work only if the ground terminals 19 and 23 are properly connected
- To achieve a correct gate travel autolearning as required, be informed that, with the board under voltage on first pulsing to open the outer driving gear speed
corresponds to the lowest pre-set setting.
- When power is back after a power failure, the self-learning mode is automatically selected in slow gate opening mode. But all the previously selected modes
stay in the memory.
