5. FAULT CONDITIONS
The following conditions cause certain effects to normal operation
of automation:
a
microprocessor error
b
safety electronic timing tripped (operation is interrupted if
continuous work time exceeds 255 sec. ).
c
limit sensors disconnected (or both engaged)
• Conditions
a
and
b
cause automation to stop and nothing
more.
• Condition
c
causes an alarm situation disabling any activity:
Normal operation can be restored only after eliminating the
alarm cause and pressing the RESET push-button (or turning off
power supply momentarily).
To have this condition signalled, the warning light must be
connected: the alarm is signalled by very rapidly flashing light
(0.25 sec).
6. ROTATION DIRECTION CHECK
1)
Release the operator, take it manually to mid-travel and re-
lock it.
2)
Power up the system and then press the RESET push-button.
3)
Give an Open command to the operator, check if the gate
moves in opening direction and then press the RESET push-
button to stop the leaf moving.
4)
If rotation direction is incorrect, change over wiring of cables
T1 and T3 of the electric motor.

7. LIMIT SENSORS CONNECTION CHECK
Command opening of the gate, and check if, with the leaf open,
the FCC LED is lighted and the FCA LED is off.
Command the gate to re-close (or wait for pause time to elapse
in case of automatic logic) and check if, with the leaf closed, the
FCA LED is lighted and the FCC LED is off.
If the LEDs are reversed, change over the cables connected to
terminals 12 and 13.
8. ELECTRICAL CONNECTIONS WITH 230V 3ph
To connect the 844 T appliance to a 3-phase 230 V mains,
observe the diagram in F ig.8.
N.B.: The electric motor of the gearmotor must be 230V 3-phase.
