3.3.4) Connection of 2 or more sensitive edges GB
The FT210 has only one sensitive edge input, but 2 or more sensitive edges that perform the same function can be cascade
connected one after the other as in figure 21 applying a single 8.2KΩ termination resistance.
Warning: the constant resistance devices must be cascade connected and never in series or parallel to one another!

4) Testing
Each individual component of the automation system requires a specific testing phase. Perform the following sequence of oper-
ations for the testing of the FT210. The sequence is repeated for each device in the event 2 devices are present, one on the
front of the gate and one on the back of the gate (see figure 3).
Warning: some points require that the gate is in movement for the control; as the automation MAY not be adequately SAFE,
the maximum attention must be given during these controls.
1. Make sure that all that is foreseen in the present manual, in particular chapters 1 "Warnings" and 3 "Installation" is fully abided by.
2. Release and fully open the gate leaf so that the TX is at the maximum possible distance from the RX.
3. Make sure that there are no obstacles between the Tx and the RX.
4. If present, disconnect the power supply to the receiver and remove the battery from the transmitter.
5. Disconnect the sensitive device from the TX terminals and measure the resistance of the device with an ohmmeter, check-
ing that the value is between 7700Ω and 8700Ω (nominal 8200Ω).
6. Push the sensitive edge to activate it and measure once again the resistance. Check that the resistance is lower than 1000Ω
or higher than 16500Ω.
7. Reconnect the sensitive device to the TX terminals.
8. Connect the power supply to the receiver and check that the L1 (Ir Level) L2 (Phototest Ko) and L3 (Sensitive Device Ko)
LEDs are on. Check that the L4 LED (Sensitive Device Ok) is off (see figure 30).
9. Remove the JP3 jumper on the TX so that it always transmits in the FAST mode.
10. If the distance between the TX and the RX exceeds 7 m check that the JP1 jumper on the TX is connected (this meaning
programmed for distances up to 15 m).
11. Insert the FTA1 or FTA2 battery into the TX (see figure 33 or 34).
12. Check that the L1 (Ir level) LED on the RX receiver flashes; the L2 (Phototest Ko) LED and the L4 (Sensitive device Ok) LEDs
are on and that the L3 ((Sensitive device Ko) LED is off.
13. If necessary, improve the alignment by directing the TX and RX lenses as shown in figure 14. By performing the L1 (Ir lev-
el) LED signal the speed of the flashing is less and the alignment is greater. The adjustment is at its best when the LED flash-
es slowly at a maximum of 3 flashes a second.
14. Repeat the test placing the top protection covers both on TX and RX. Note that the RX cover is fitted with a damper filter
that simulates adverse weather conditions which could arise during use.
15. Move the gate leaf along the entire course and check, through the flashes of the L1 LED, that the alignment remains above
the optimum.
16. To check the optical presence sensor (type D) of
the FT210, and to make sure that there is no interfer-
ence with other devices, pass a 50 mm diameter cylin-
der across the optical axis, first near the TX, then near
the RX and finally between the two (see figure 22) and
make sure that in all cases the device is triggered,
switching from the active status to the alarm status
(LED L1 ON) and vice versa.
