This control panel is powered by 120V AC across terminals
L1 and L2, protected by a 3A fuse on the main power line.
The control systems are powered by low voltage (24V AC)
and protected by a 2A fuse.
A 10A fuse protects the motor.
The total power consumption of 24V accessories must not
exceed 40 W.
Safety
Photoelectric sensors, magnetic loop detectors or any other
safety device can be connected to the control panel to
obtain:
a) Reversal of the arm during the closing cycle.
Connect safety device to terminals 2-C1;
b) Total Stop: the movement of the barrier arm is interrupted
and the automatic closure cycle is deactivated. To resume
the movement of the barrier arm, an intended input is
required, from a pushbutton or the radio transmitter.
Connect safety device to terminals 1-2;
c)Immediate Closure: the barrier arm is lowered
automatically after the vehicle has passed the safety
devices.
Connect device to terminals 2-C5;
- Obstacle detection safety device: see NOTE;
- Fixed operating time of 20 sec.
- LB35 board, Battery backup (Use three 12V 7Ah
batteries), see page 9;
Accessories that can be connected to this unit
- Flashing signal light when barrier arm is in motion;
- Plug-in radio receiver;
- Keypads, card readers, telephone entry systems and most
other access control devices.
5.0 ZL37UL CONTROL PANEL TECHNICAL DESCRIPTION
Other functions
- Automatic closing: The automatic closure timer is
activated as the arm reaches the opening limit. The
adjustable timer is subject to the intervention of the safety
accessories and is deactivated after a 'total' stop, a detection
by the obstacle detection device or when power is
unavailable, Dip switch 1 ON;
- Obstacle detection: When the motor is stopped (arm is
closed, open or half-open after an emergency stop
command), the radio transmitter and the control pushbutton
will be deactivated if an obstacle is detected by the
secondary safety devices (for example, the photocells), Dip
switch 6 ON;
- “Manual Operation” (controlled by continuous pressure
of a pushbutton only), automatic closure and radio control
are disabled, Dip switch 4 ON;
- Flashing light activated before the opening and closing
cycle begins, dip switch 5 ON;
- 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 13), Dip switch 7 ON;
- Function that increases the soft stop action on the barrier,
Dip switch 10 ON;
- Selection of command sequence: open-close-reverse;
open only, see Dip switch 2.
Adjustments
- Automatic closing time;
- Sensitivity of the inherent obstacle detection safety
system.
Important: Disconnect power and disconnect the batteries
before servicing the unit.
Note
5.1 MOTHERBOARD
The Inherent Obstacle Detection Device upon sensing an obstruction, during opening or closure and before the arm has
reached the slowdown limit switches, reverses the direction of the arm and disables the automatic closure. After the arm
has reached the slowdown limit switches it will stop and disable the automatic closure.
