TECHNICAL DESCRIPTION OF ZL37F
CONTROL PANEL
This control board is powered by 230V a.c. across terminals L1 and L2, and is protected by a 3.15A
fuse on the main power line. Control systems are (24) powered by low voltage and protected with by
a 2A fuse. The total power consumption of 24V accessories must not exceed 20 W.
SAFETY
Photocells can be connected to obtain:
a) Re-opening during the closing cycle;
b) Total stop: the movement of the bar is interrupted, and the automatic closure cycle is disactivated.
Use the keyboard or the radio transmitter to resume movement of the bar;
- Amperometric safety device: see
NOTE;
- Fixed operating time of 20 sec.
OTHER FUNCTIONS
- Automatic closing: The automatic closing timer is automatically activated at the end of the opening
cycle. The preset, adjustable automatic closing time is automatically interrupted by the activation of
any safety system, and is deactivated after a total stop command or in case of power failure;
- Immediate closure (the bar is lowered automatically after the vehicle has passed the safety devices,
on the terminals 2-C5 of the control panel;
- "Operator present" function. Bar operates only when the pushbutton is held down (the radio remote
control system is deactivated);
- Obstacle detection: When the motor is stopped (bar is closed, open or half-open after an
emergency stop command), the transmitter and the control pushbutton will be deactivated if an
obstacle is detected by one of the safety devices (for example, the photocells);
- Flashing light activated before opening and closing cycle begins;
- Activation of a 24V output signal during the movement phases and in the closed position;
- "Slave" operation when two motors are used in combination (see page 22);
- Increases the braking action on the barrier;
- Selection of command sequence: open-close, open only.
ACCESSORIES CONNECTED IN SERIES
- Flashing signal light (25W max.), when bar is in motion.
OPTIONAL ACCESSORIES
- Open barrier pilot lamp (3W max.). This is a light that indicates the barrier open position and turns
off when the barrier activates the closing end-stop (terminals 10-5);
- LB35 board, used to power the automation system using battery power in case of a power failure.
When the power supply is restored, the batteries are recharged automatically (refer to instruction
sheet);
ADJUSTMENTS
- Sensitivity of amperometric safety system: min./max.
- Automatic closing time
