t1
PHOTOCELLS TEST
MINIMUM:
n
MAXIMUM:
y
Before enabling this function (
t1
=
y
), check that the negative of the PHOTOCELL TRANSMITTERS is connected to terminal 19 label t1.
Connect ONLY the negatives of the TRANSMITTERS to terminal 19 and no other signals.
Before starting a closing or opening operation, the control unit removes power from the photocells checking that the contact is open.
Once the opening of the contact has been checked, the control unit supplies the photocells again, checking the closure of the contact (the
photocells are associated with signals type N.C. NORMALLY CLOSED).
If the check is successful, the required operation is started. If the check fails, the control unit display will indicate
1t
and the gate will not
be started. The photocell test will only be carried out on installed photocells.
For example: if the system only uses the photocell when closing, ensure that parameter
e4
is set to
tC
or
td
(functions relating to the
photocell) and that the parameter
e5
is disabled (
e5
= n - see “GENERAL FUNCTIONS”).
In this way, the control unit will know which terminal the photocell is connected to and will not carry out the test on the unused terminal.
t2
MOTORS
MINIMUM:
n
MAXIMUM:
y
Before each operation, the control unit carries out the test of motor A and the test of motor B.
If the test is successful, the requested operation is started. If the test fails, the display shows:
-

error motor B
The motor test fails in 4 cases:
- Motor THERMAL CUTOFF TRIGGERED
- CONNECTION ERROR
