PHOTO TEST
For the photo test to work, the system must have two power supply lines for the photocells, the first being connected to terminals
10 and 11, which power the receivers, and the second to terminals 12 and 13, which power the transmitters (the photo test must
be enabled with dip-switch No. 7 in the ON position). The control unit checks the efficiency of the photocells by simulating an
activation at every start of gate movement. If everything is OK the motor starts up, thereby starting the gate movement; if the
receiver has any problems the cycle stops and the open gate light blinks several times to warn of the situation.
- The photo test also works with photocell 2 (Jolly input).
- With the photo test enabled and the control unit in standby, the photocell transmitters are not powered
and the FT1 input is open (LED off). Operation of the photocells may still be checked in this condition by
short-circuiting the test jumper (part.12 di Fig 1).
TRIAC TEST
Failure of this component could jeopardise installation operation and safety.
That is why a control prior to every gate movement has been inserted.
Should there by any malfunction, the control unit locks and the open gate warning light blinks slowly.
USE OF THE OC2 RECEIVER (part 10 of fig. 1)
The operation and programming of the OC2 series receiver (fig. 3) is outlined in the instructions supplied with the
receiver.
Please note that the receiver channel 1 always corresponds to the step-by-step (P/P) control on the control unit,
while channel 2 is allocated to the pedestrian control.
T101F/FA control unit for up-and-over doors
The T101F/FA operation is identical to that of the T101 version, with the exception of the functions of dipswitches 8,9 and
10 (part 11 of fig.1).

T101FA
The T101FA control unit is a variant of the model T101F, with the same electrical and operational specifications; the only
difference lies in the method of limiting the motor torque.
The system adopted on the T101FA has the advantage of eliminating vibrations, which could be generated by the motor on up-and-over door installations.
NOTES
- The power on deceleration (settable by means of dipswitch no. 9) is proportional to the set voltage.
- At the start of each manoeuvre, for approx. 1 second, maximum power is delivered to the motor (start-up current).
- The trimmer on the board (detail 8) must be excluded by closing JP1 (detail 9) fig.4.
