IMPORTANT SAFETY REQUIREMENTS & INSTRUCTIONS
WARNING To reduce the risk of injury or death:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Never let children operate or play with gate controls.
Keep the remote control away from children.
3. Always keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.
4. Test the Vehicular Gate Operator monthly. The gate
MUST reverse on contact with a rigid object or stop
when an object activates the non-contact sensors.
After adjusting the limit of travel, retest the Vehicular
Gate Operator. Failure to adjust and retest the
Vehicular Gate Operator properly can increase the
risk of injury or death.
5. Use the Emergency Release only when power switch
or circuit breaker has been turned off. Using the Emer-
gency Release during a power failure can be a
hazard if power is abruptly restored.
6. KEEP GATES PROPERLY MAINTAINED. Read the
Owner’s Manual. Have a qualified service person
make repairs to gate hardware.
7. The entrance is for vehicles only. Pedestrians must
use separate entrance.
8. SAVE THESE INSTRUCTIONS.
WARNING: Do not install this gate operator if you do not have experience or appropriate
training with gate operators.

Prior to installation, the following must
be observed: (per UL 325.51.8.4).
a) Install the vehicular gate operator only when:
1) The Vehicular Gate Operator is appropriate
for the construction of the gate and the usage
class of the gate.
2) All openings of a horizontal slide gate are
guarded or screened from the bottom of the
gate to a minimum of 4 feet (1.2 m.) above
the ground to prevent a 2 1/4 inch (57.15 mm.)
diameter sphere from passing through the
openings anywhere in the gate, and in that
portion of the adjacent fence that the gate
covers in the open position.
3) All exposed pinch points are eliminated or
guarded.
4) Guarding is supplied for exposed rollers.
b) The Vehicular Gate Operator is intended
for installation only on gates used for vehicles.
Pedestrians must be supplied a separate
access opening.
c) The gate must be installed in a location so that
enough clearance is supplied between the gate
and adjacent structures when opening and
closing to reduce the risk of entrapment.
Swinging gates shall not open into public
access areas.
d) The gate must be properly installed and work
freely in both directions prior to the installation
of the Vehicular Gate Operator. Do not over-tighten
the operator clutch to compensate for a damaged
gate.
e) Controls must be far enough from the gate
so that the user is prevented from coming in
contact with the gate while operating the
controls. Controls intended to be used to
reset a Vehicular Gate Operator after 2
sequential activations of the entrapment
protection device or devices must be locat-
ed in the line-of-sight of the gate. Outdoor or
easily accessible controls shall have a
security feature to prevent unauthorized use.
f) All warning signs and placards must be installed
where visible in the area of the gate.
g) For Vehicular Gate Operators utilizing a non-
contact sensor in accordance with 30A.1.1
Type B1 non-contact sensor (photo electric
sensor or the equivalent).
1) See instructions on the placement of non-
contact sensors for each type of application.
2) Care shall be exercised to reduce the risk of
nuisance tripping, such as when a vehicle,
trips the sensor while the gate is still
moving, and.
3) One or more non-contact sensors shall be
located where the risk of entrapment or
obstruction exists, such as the perimeter
reachable by a moving gate or barrier.
h) For a Vehicular Gate Operator utilizing a contact
sensor in accordance with 30A.1.1
1) One or more contact sensors shall be located
at the leading edge, trailing edge, and post-
mounted both inside and outside of a vehicu-
lar horizontal slide gate.
2) One or more contact sensors shall be located
at the bottom edge of a vehicular vertical lift
gate.
3) One or more contact sensors shall be located
at the pinch point of a vehicular vertical pivot
gate.
4) A hardwired contact sensor shall be located
and its wiring arranged so that the commu-
nication between the sensor and the vehic-
ular gate operator is not subjected to mechani-
cal damage.
5) A wireless contact sensor such as one that
transmits radio frequency (RF) signals to
the vehicular gate operator for entrapment
protection functions shall be located where
the transmission of the signals are not
obstructed or impeded by building struc-
tures, natural landscaping or similar
obstruction. A wireless contact sensor shall
function under the intended end-use condi-
tions.

TERMINAL STRIP CONNECTIONS
Terminal # 1 - COMMON:
Low voltage common.
Terminal # 2 - REV LOOP:
Stops the gate from closing. If the gate is open,
it holds the gate open. If the gate is closing, it
stops and reopens the gate. If the gate is closed,
the gate will remain closed. The function can be
altered with Dip Switch "C" 4 (see “Dip Switch
Configuration”). Used with loop detectors, photo
eyes, safety edges…etc. Becomes active with a
closed contact to common.
Terminal # 3 - CLOSE:
Closes the gate. Used with three button stations
or pushbuttons. Becomes active with a closed
contact to common.
Terminal # 4 - FIREBOX:
Opens the gate. Used with fire department key
switches & controls. Opens with closed contact
to common. Closes immediately when closed
contact on common is removed.
Terminal # 5 - EXIT:
Opens the gate. Used with loop detectors, photo
eyes, keypads, phone entry systems, three-but-
ton stations…etc. Becomes active with a closed
contact to common.
Terminal # 6 - PHANTOM:
Keeps the gate open when the open limit switch
is activated. Used with loop detectors. Becomes
active with a closed contact to common.
Terminal # 7 - RADIO:
Operation depends on dip switch "C" 3 (See “Dip
Switch Configuration”). Used with an RF receiver
or pushbutton. Becomes active with a closed
contact to common.
Terminal # 8 - EDGE:
When triggered the gate will stop. The gate
will remain stopped until the detector is cleared.
Once the detector is cleared, the operator will
resume normal operation. If triggered twice
before reaching a limit switch, the alarm will
sound for 6 minutes and the control board will not
accept any commands. After the 6 minutes the
24 VDC is removed from the alarm connection
and the board resets to normal operation.
Terminal # 9 and 10 - LIMIT 1 & LIMIT 2:
Direction depends on Dip Switch "C" 7 (See “Dip
Switch Configuration”). Stops the motor from
moving in one direction. These wires are preset
in factory and should not be moved. Becomes
active with a closed contact to common.
Terminal # 11 and 12 - COMMON:
Low voltage common.
Terminal # 13 - +24 VAC:
Provides 24 VAC for peripheral accessories.
Terminal # 14 and 15 - MAG (-) & MAG (+):
Supplies 24 VDC to a Magnetic Lock when the
gate is closing or closed. If gate is opening or
opened, then no power is supplied. Leave open
if not used.
Terminal # 16 - M BRAKE:
Used ONLY on the Ram 50 Operator. If while the
gate is closed someone or something tries to
manually open the gate without a proper signal
(keypad, exit loop, radio signal…), the motor will
lock up for 6 minutes. After the 6 minutes, the
operator will then secure close the gate.
Terminal # 17 and 18 - MOTOR 1 & MOTOR 2:
Supplies power to the motor. Direction depends
on Dip Switch "C" 7 (see “Dip Switch Configura-
tion”). These wires are preset and connected in
the factory and should not be moved.
Terminal # 19 and 20 - AC HOT & NEUTRAL:
110 VAC or 220 VAC to power the operator.
Voltage is predetermined at factory and cannot
be changed by the installer or technician.

RAMSET “INTELLIGATE” CONTROL BOARD
Introduction:
Ramset’s “Intelligate” Control Board works
with Sliding, Swinging and Overhead vehicular
gate operators. It is controlled by a program-
mable microprocessor that reads and precisely
executes all functions of the Control Board.
The Control Board is powered by a separate
mounted 24 VAC transformer. This allows no neces-
sary board modifications between 110 VAC and
220 VAC single-phase applications. Some of the
functions of the Control Board are: 0 - 60 seconds
automatic close timer, self adjusting E.R.D. with low
and high setting, constant warning, pre warning,
secure close, one pass, open & close delay, left/right
hand operation, plug-in loop detectors and RS485
three wire master/slave connection.
