Limit Switch And Encoder - V2 CITY2+ Instrucciones De Uso Y Cuidados

6.10 - LIMIT SWITCH AND ENCODER

The CITY2+ controller can control the gate's travel using a limit
switch and/or an encoder.
m
CAUTION: The use of these devices is strongly
recommended to ensure that the gate opens and closes
correctly.
The speed of operation of the DC motors can be conditioned by
variations in mains power, atmospheric conditions, and friction of
the gate.
Furthermore, encoders also allow the controller to determine if
the gate stops in an irregular position due to an obstacle.
For encoder operation, it is required that the closure position for
each section of the gate be detectable using a limit switch sensor
or a mechanical stop.
Each time the controller is turned on, to realign the encoders, the
gate is closed until it reaches the limit switch or the mechanical
stop.
The control unit supports two kinds of end of stroke:
• end of stroke equipped with a normally close switch that will
be opened as soon as the door reaches its position desired (set
FC.En L.SW
the parameter =
• end of stroke in series of motor winding (set the parameter
FC.En Cor.0
= )
GATES WITH TWO PANELS
For gates with two panels, limit switches and encoders share the
same terminals so it is not possible to install both of these devices
at the same time.

PLEASE NOTE: refer to the motor manual
Installation of limit switch
• Connect the open limit switch to motor 1 using terminals
K1 (FCA1) and K5 (COM)
• Connect the close limit switch to motor 1 using terminals
K2 (FCC1) and K5 (COM)
• Connect the open limit switch to motor 2 using terminals
K3 (FCA2) and K5 (COM)
• Connect the close limit switch to motor 2 using terminals
K4 (FCC2) and K5 (COM)
Installation of encoders
• Connect the negative feeds (BLACK cable) for both encoders to
terminal K5 (COM)
• Connect the positive feeds (RED cable) for both encoders to
terminal K6 (+)
• Connect the encoder outputs (BLUE / WHITE) to motor 1 using
terminals K3 (FCA2) and K4 (FCC2)
• Connect the encoder outputs (BLUE / WHITE) to motor 2 using
terminals K1 (FCA1) and K2 (FCC1)

Check that the two pairs of wires have been correctly
connected and after installation proceed as follows:
1. Disable encoder operation (
2. Set a meaningful open delay (
NOTE: The default settings in the controller satisfy points 1
and 2.
3. Give a START command:
- If both gate panels move, the wires are connected correctly
- If Err7 appears on the display once panel 1 starts to move,
invert the wires connected to terminals K3 (FCA2) and K4
(FCC2)
Err7
- If appears on the display once panel 2 starts to move,
invert the wires connected to terminals K1 (FCA1) and K2
(FCC1)
GATES WITH SINGLE PANELS
Installation of limit switch
• Connect the open limit switch to terminals K1 (FCA1) and
K5 (COM)
• Connect the close limit switch to terminals K2 (FCC1) and
K5 (COM)
Installation of encoder
• Connect the negative feeds (BLACK cable)
to terminal K5 (COM)
• Connect the positive feeds (RED cable)
to terminal K6 (+)
• Connect the encoder output (BLUE / WHITE) to terminals
K3 (FCA2) and K4 (FCC2)
Check that the two encoder wires have been correctly connected
and after installation proceed as follows:
1. Disable encoder operation (Enco menu)
2. Give a START command:
- If the gate moves, the wires are connected correctly
Err7
- If appears on the display once the gate starts to
move, invert the wires connected to terminals K3 (FCA2)
and K4 (FCC2)
