WARNING
:
Depending on the installation, this anti-crushing system
is not enough to comply with EN13241, EN12978 and EN12453, and to
avoid accidents with people and animals, requiring the use of photocells
and safety edges.
Even using the inherent anti-crushing system, it is recommended to use
passive edges for better performance and protection.
ENCODER OPERATION TEST
It is possible to test the encoder of the operator by connecting it to the board and
checking if the “ENC” LED is flashing when the operator is moved.
EVENTS AND FAILURES INDICATIONS
Microcontroller operation indication
The main function of the “OSC” LED is to indicate that the controller board is operating.
It flashes with a fixed frequency of ~ 1 Hz, since the power is turned on.
Motor over current or short circuit
The “OSC” LED flashes rapidly (in a 0.1- second interval) to warn that the power
stage has tripped due to overcurrent or short circuit in the motor. The board may
operate normally after 10s of the occurrence of the overload.
Overheating
The “END” LED flashes rapidly, in a 0.1-second interval, to warn that the power stage
has tripped due to overheating of the heatsink of the environment. The operator can
only be operated again if the temperature decreases to less than 100ºC.
EEPROM fault
The “OSC” LED flashes twice when Memory is not present.
EEPROM with invalid data
The “OSC” LED flashes three times when Memory is present but it has a content that
the microcontroller does not identify as a Valid Transmitter Code.
MAINTENANCE ANd TROUbLESHOOTING
In the table below are found some PROBLEMS - DEFECTS, PROBABLE CAUSES AND
CORRECTIONS - which may occur in the operator. Before any maintenance, it is
necessary to completely disconnect the power grid.
Open limit switch
The “END” LED flashes when the gate reaches an open limit switch.
Closed limit switch
The “END” LED is lit when the gate reaches a closed limit switch.
Load in the capacitors
The “BUS” LED indicates that there is load on the power stage capacitors.
WARNING:
The power region (capacitor region) of the board
must not be touched while this LED is lit even after the inverter is
disconnected from the electricity grid!
Command
The “CMD” LED on indicates that the control panel is receiving some command
from the digital inputs, such as OPE, CLO, PBU, SFO or SFC.
DEFECTS
PROBABLE CAUSES
CORRECTIONS
Motor does not start /
does not move
A) Power grid off
A) Make sure the power grid
is turned on correctly
B) Open/ Burned
fuse
B) Replace fuse with the same
specification
C) Locked gate
C) Make sure that there are
no objects blocking the gate
operation
D) Limit switch with
defect.
D) Replace the limit switch
system (analog and / or
digital)
