11 - PHOTOCELLS

The unit has two inputs for photocells (normally closed contact),
which can be independently enabled and associated with different
functions:
Connect the N.C. output of the photocell 1 (FOT1) between
terminals S5 and S9
Connect the N.C. output of the photocell 2 (FOT2) between
terminals S6 and S9
m
WARNING:
• If you connect multiple photocells on the same terminal, the
connection must be done in series: all photocells will have the
same function.
• If you do not connect any photocell to terminal S5,
the menu must be set to
FOT1
• If you do not connect any photocell to terminal S6,
the menu must be set to
FOT2
Regardless of the selected function, if the photocells are activated
during the pause, the pause time is reset using the value set in
parameter .

NOTE: if the photocells are connected on the two FOT1 and
FOT2 inputs the door stops only after the passage in front of both
photocells have been detected

Below the behaviour of the door when the photocell is interrupted
is described, based on having set parameter
on the position of the door.
It is assumed that the

Figure A on the page to the side shows activation of the
photocell while the door is found to be above 40% of the total
height.
Figure B shows the same situation, but with the door below
40%.
Figure C shows activation of the photocell when the door has
already activated the photocell masking switch, connected to
terminals H3-H5.

1. Active photocells when opening and closing -
• During closure of the door, if the photocell is interrupted the
following scenarios can be checked based on the configuration
of the
P.AP.F
door:
- In case A the door re-opens immediately
- In case B the door shuts: when it is released the photocell
re-opens completely.
• During opening of the door, if the photocell is interrupted the
following scenarios can be checked based on the configuration
of the
P.AP.F
door:
- In case A the photocell is bypassed
- In case B the door shuts: when the photocell is released it
starts opening again.
• Closed door, if the photocell is interrupted the start-up
commands are rejected (by setting
bypassed and the start-up commands are accepted).
• Open door, if the photocell is interrupted the pause time is
reloaded, and the closure commands are rejected.
2. Masking function -
This function may serve with the curtain doors which, by billowing
during closure, may interrupt the photocell beam.
m
A switch must be positioned immediately above the
photocell and the N.C. contact must be connected to terminals
H3 and H5. When the contact opens the photocell is bypassed.
NOTE: configure the
The function of the doors is the same as point 1, but if the
photocell ray is blocked during closure, when the door has already
activated the switch attached between terminals H3-H5 (case C),
the photocell is bypassed and the door continues to close.
3. Anti-dragging function -
Intervention of the photocell during the first part of the door
opening indicates the possibility that the operator has accidentally
remained hooked.
This function serves to avoid the operator being lifted up from the
moving door.
Operation of the door is the same as point 1, but if the photocell
you ray is interrupted when the door begins opening or finishes
closing (case B), the door closes.
To make it restart, the following operations must be carried out:
1. Release the photocell ray
2. Press the emergency stop button connected to terminals T1-T2
and rearm it
3. Send a start-up command
, and
NOTE: if the emergency stop button is not installed, use of this
function is not recommended
