WARNING: Not following these instructions may

cause severe injury or death to person

IMPORTANT SAFETY INSTRUCTIONS

WARNING - To reduce risk of severe injury or death:

1) READ AND FOLLOW ALL INSTRUCTIONS

2) Never let children operate or play with door controls. Keep the remote control away
from children.

3) Always keep the moving system in sight and away from people and objects until it is
completely closedor stopped. NO ONE SHOULD CROSS THE PATH OF THE
MOVING SYSTEM.

4) Test the system gate operator monthly. The system MUST reverse on contact with a
rigid object or when an object activates the non-contact sensors. To obtain a reverse on
contact with an object on hydraulic linear and in-ground operators SEA recommend to
install the patented safety device “SAFETY GATE” for each leaf.
After adjusting the force or the limit of the travel, retest the gate operator. Failure to
adjust properly the gate operator properly can increases the risk of severe injury or
death.

5) Use the manual release only when gate is not moving

6) KEEP GATES PROPERLY BALANCED AND MAINTAINED. An improper balancing
or maintenance increases the risk of severe injury or death. Have a qualified service
personal to make repairs to cables, spring assemblies and other hardware.

7)The entrance with a gate operators system is for vehicles only. Pedestrian MUST use
separate entrance.

8) Every gate operator installation MUST have secondary protection devices against
entrapment, such as edge sensors and photo beams more in particularly in places
where the risk of entrapment is more likely to occure.

END USER ISTRUCTIONS

The installer is responsible for grounding the operator system,
for providing the main power breaker switch, and for making sure
that the entire gate systems meets all applicable electrical codes.

Good grounding and proper surge suppression are an integral part of proper installation for
a gate operator system. One or all of the following may require surge suppressors: high
voltage power lines, low voltage power lines, telephone lines, data lines, low voltage control
lines and loops. How much surge suppression is required depends upon how susceptible
the area is to lightning and power surges. Regardless, good grounding is essential. To
realize maximum protection, proper grounding and proper surge suppression is absolutely
necessary.

If the circuit breaker box is located close to the gate operator system, for example, in a
guard house, then the ground from that circuit can be used to ground the gate operator
system. Eliminate all 90° bends in ground wires and keep a minimum of three feet between
the surge suppressor and the equipment being protected.

If the power source or circuit breaker box is not located close to the gate operator system an
Isolated Ground Zone (IGZ) needs to be created. An IGZ can also be created if the circuit
breaker box is located close by the gate operator system. An IGZ is an imaginary circle
drawn around the gate operator system. The gate operator system not only includes the
gate operators and control panel, but all of the accessories and devices associated with it at
that controlled entry point. This includes loop detectors, card readers, digital entries,
telephone entries, any device that has a ground or requires a ground and ali of the surge
suppressors. The ground bus is a common ground point calied a Single Point Ground
(SPG). It is used to bond all the equipment and device grounds in the IGZ together. The
SPG is very important because it helps eliminate different ground potentials that can be
present on the equipment. In such cases, equipment damage occurs even with surge
suppressors.

GATE 2

GROUNDING

Do not use or connect the ground wire coming from the circuit breaker box. By using an
Isolated Ground Zone, you are separating the gate operator system from the house or
building ground. This eliminates ground potentials. It is recommended that the ground bus
be located in a separate NEMA type enclosure. All grounds will be tied to this ground bus.
Some points to remember:

Keep all ground wires as straight as possible. Do not have any sharp 90° bends. Have a
minimum of 3 feet of wire between the surge suppressor and the equipment being
protected.

Equipment ground wire should be a minimum of 12 AWG. The main ground wire from the
bus bar to the ground rod shouid be an 8 or 6 AWG copper wire. Ground rod should be a
minimum of 10 feet in length, longer depending on local soil conditions.

For more information regarding good grounding practices check: National Electric Code
art. 250; IEEE Emerald Book, standard 100; International Association of Electric
Inspectors.

DIP 3 AND DIP 4 PROGRAMMING FOR AUXILIARY INPUT CONFIGURATION

SAFETY EDGE ( N.C. contact)

When the Safety Edge Contact opens, the gate reverses direction and stops after about 1 second. A
START command is required to restart movement

TIMER (N.O. contact)

If a TIMER is connected to this input the gate can be opened and kept open as long as the contact
remains closed. Using a 24-hour or 7-day timer allows gate opening times to be scheduled as
required. When the TIMER contact is open the automatic operation functions according to pre-set
logics.

PROGRAMMING OF OTHER DIPS FOR OTHER FUNCTIONS

LEAF DELAY IN OPENING AND CLOSING

Activating this function, the Leaf Delay in opening and closing will be eliminated. Both leaves will
work simultaneously. It is advised to activate this function on single leaf applications and/or in
applications where the Delay is not required.

PRE-FLASHING

When this function is activated the flashing lamp and warning light begin flashing about 3 seconds
before the motor starts, both when closing and opening.

AUTOMATIC CLOSING

Activating this function causes the gate to close automatically, after the time set by the trimmer Rv3.
This function can be activated independently of the operating logic set (DIP SWITCH 1 and 2).

PHOTOCELL AUTOTEST
When this function is activated a test is carried out on the photocells before any gate movement
takes place. To enable this function the photocell transmitter must be connected to terminals 13
(24V) and 17 (Negative) of connector CN2.
The flashing lamp and troubleshooting LED will both flash slowly if a malfunction occurs.

ENCODER MANAGEMENT (reversing sensor)

The signals sent from an encoder located on the motor or gate are managed when this function is activated.
This results in any obstacles found in the gate's path being detected and reverses the gate direction of
movement for one second, it stops and waits for commands. The flashing lamp and troubleshooting LED will
both flash slowly if a malfunction occurs. With a following start the automation will proceed in slow down
speed until it reaches the stop. Note: After two consecutive obstacles the BUZZER will be activated.

P.N.: If an encoder is not fitted, set the DIP SWITCH to OFF.
Note: The Encoder sensibility can be adjusted through the PALM or through the pushbuttons Ptime
and Pcode on board of the control unit.

“SOFT” START

When this function is activated, the motor will start at a lower torque to avoid stresses and strains on
the gate's mechanical components. The starting torque is a percentage of the normal operating
torque.
P.N.: It is not advised to operate this function when the gate is very heavy or does not run smoothly.

BRAKING (slow-down) AT LIMIT SWITCH

When this function is activated motor speed reduces slowly before the limit switch is reached or
before the end of the operating time. This function is designed to bring the leaf gently up to the stop
position and prevent the gates clashing. The closing speed is fixed, while the slow-down time can be
adjusted using the trimmer Rv2.

Remember to set this DIP in Off position in case of mechanical or hydraulic brake.

! !

It is necessary to activate this function to choose the slow-down modality through jumper J1.

LEAF LOCKING

When this function is activated, at the end of the slow-down phase, and when the leaf is up against
the mechanical stop, the motor is supplied at maximum power for about 1 second. This increases
the oil pressure in the motor and makes the hydraulic lock more effective.

P.N.: this function SHOULD NOT be activated when used on sliding gates since it could
cause over-running of the limit switches and the automation system to jam.
Note2: With the Palm through the function PushOpen it is possible to exclude the tightening
of the leaf during the opening phase.

REVERSING STROKE

This function (to use exclusively on swing gates) is used to facilitate the electric lock release. Before
beginning the opening cycle, as soon as the start order is given, the leaves are supplied for about 1
sec. in closing.
