BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPENER:
watch the enclosed video and read these instructions carefully and completely
to become familiar with all parts and installation steps. The video is only designed
as an overview of the installation procedure. You must read the installation manual
for detailed instructions on gate opener safety and proper use of the gate opener.
Thank you for purchasing a Mighty Mule® 202 E-Z Gate Opener(50hTEPJUZPVSTFMGBVUPNBUJDHBUF
opener! When correctly installed and properly used, your Mighty Mule® E-Z Gate Opener will give you many
years of reliable service. Please read the following information and watch the enclosed video to ensure you have
the correct system for your particular needs. Furthermore, this manual and the video will enable you to properly
install your Mighty Mule® E-Z Gate Opener.
The Mighty Mule® 202 Gate Opener is designed for installation on pull-to-open dual gate leafs (gates that
open into the property). By purchasing an accessory bracket (FM148), the Mighty Mule® 202 Gate Opener
can accommodate push-to-open dual gate leafs (gates that open out from the property). The gates must not
exceed 12 feet and 300 pounds per leaf (please see Technical Specifications on page 10). The Mighty Mule®
E-Z Gate Opener can be used on vinyl, aluminum, chain link, farm tube, and wrought iron gates. Use on solid
gates is not recommended. Solid surface gates have a high resistance to the wind.
The Mighty Mule® E-Z Gate Opener accommodates extra transmitters, digital keypads, solar panels, push
buttons, automatic gate locks, and other access control products. These optional accessories (see the enclosed
Mighty Mule® Accessory Catalog) are available at most stores. Your store should be able to special order any
accessory not in stock. If your store cannot special order accessories, please call the GTO Sales Department
(800-543-GATE).
The Mighty Mule® E-Z Gate Opener features adjustable obstruction sensing. This safety feature makes
the gate stop and reverse direction within 2 seconds when it comes in contact with an obstruction. MIN is the
factory setting; meaning the gate will exert the minimum force on an obstruction before it stops and reverses
direction.
The Mighty Mule® E-Z Gate Opener also has an adjustable auto-close feature. After the gate reaches the
fully open position, it can be set to remain open up to 120 seconds before automatically closing. Pressing the
transmitter button at any time after the gate opens fully will cause it to close immediately. OFF is the factory
setting; meaning the gate will stay open until you press the transmitter (or keypad, etc.) again.
PLEASE NOTE—If your application requires any of the following:
Column Mounting;
Slide gates;
Swing gates longer than 12 feet or weighing more than 300 pounds;
Professional installation;
please call GTO at (800) 543-GATE [4283] or (850) 575-0176 for information about our GTO/PRO professional
line of gate openers and accessories. Our Sales Department will be glad to give you the name and phone
number of a GTO/PRO dealer near you.

E-Z GATE OPENERS
Use on solid (surface) gates is not recommended. Solid surface gates have a high
resistance to the wind. If the wind is strong enough, the opener will obstruct and
stop, blow fuses, or may damage the equipment.
IMPORTANT SAFETY INSTRUCTIONS
Mighty Mule 202
1
Because automatic gate openers produce high levels of force, consumers need to know the potential
hazards associated with improperly designed, installed, and maintained automated gate opener systems.
Keep in mind that the gate opener is just one component of the total gate operating system. Each
component must work in unison to provide the consumer with convenience, security, and safety.
This manual contains various safety precautions and warnings for the consumer. Because there are many
possible applications of the gate opener, the safety precautions and warnings contained in this manual
cannot be completely exhaustive in nature. They do, however, provide an overview of the safe design,
installation, and use of this product. CAREFULLY READ AND FOLLOW ALL SAFETY PRECAUTIONS,
WARNINGS, AND INSTALLATION INSTRUCTIONS TO ENSURE THE SAFE SYSTEM DESIGN,
INSTALLATION, AND USE OF THIS PRODUCT.
Precautions and warnings in this manual are identified with this warning symbol. The symbol
identifies conditions that can result in damage to the opener or its components, serious injury, or death.
Because GTO automatic gate openers are only part of the total gate operating system, it is the
responsibility of the consumer to ensure that the total system is safe for its intended use.
Disconnecting the Opener
1. Turn opener power switch OFF.
2. Remove hairpin clip, clevis pin, and
bushing from the front mounting point.
3. Remove the opener from the mount.
The gate can be opened and closed
manually when the opener is disconnected.
NOTE: Substitute a Pin Lock (FM133) for the clevis pin on
the front mount only of the gate opener to prevent unauthorized
removal of the opener from the gate
(see Accessory Catalog).
To Manually Open and Close the
Gate, Follow the Procedure Below:
CAUTION: The gate will move freely and uncontrolled when the gate opener
is removed from the gate. ONLY disconnect the opener when the opener power
switch is OFF and the gate is NOT moving.
Clevis
Pin
Hairpin Clip
Gate Bracket
Front Mount
Bushing
CAUTION: Because the Mighty Mule gate opener
is battery powered, disconnect the opener ONLY when the
power switch on the opener is turned OFF. Unplugging the
transformer does not turn power to the opener OFF.
IMPORTANT: NEVER allow opener arm to hang
by the front mount - it will break from the arm weight.
IMPORTANT SAFETY INSTRUCTIONS

Mighty Mule 202
For The Consumer
WARNING: To reduce the risk of injury or death:
1. READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction
manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible.
2. When designing a system that will be entered from a highway or main thoroughfare, make sure the
system is placed far enough from the road to prevent traffic congestion.
3. The gate must be installed in a location that provides adequate clearance between it and adjacent
structures when opening and closing to reduce the risk of entrapment. Swinging gates must not open
into public access areas.
4. The gate and gate opener installation must comply with any applicable local codes.
I. Before Installation
1. Verify this opener is proper for the type and size of gate, its frequency of use and the proper class rating.
2. Make sure the gate has been properly installed and swings freely in both directions. Repair or replace
all worn or damaged gate hardware prior to installation. A freely moving gate will require less force to
operate and will enhance the performance of the opener and safety devices used with the system.
3. Review the operation of the system to become familiar with its safety features. Understand how to
disconnect the opener for manual gate operation (see page 1).
4. This gate opener is intended for vehicular gates ONLY. A separate entrance or gate must be installed
for pedestrian use (see page 6).
5. Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS
THE PATH OF A MOVING GATE.
6. Pay close attention to the diagram below and be aware of these areas at all times.

Entrapment Zones for a proper Pull-To-Open installation:
Zone 1 – leading edge of the gate and the fence post.
Zone 2 – between the gate and the gate post.
Zone 3 – the path of the gate.
Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc.
Zone 5 – pinch points between the opener and gate.
II. During Installation
1. Install the gate opener on the inside of the property and fence line. DO NOT install an opener on the
outside of the gate where the public has access to it.
2. Be careful with moving parts and avoid close proximity to areas where fingers or hands could be pinched.
3. Devices such as contact sensors (safety edges) and non contact sensors (photo beams) provide
additional protection against entrapment.
4. If push buttons or key switches are installed, they should be within sight of the gate, yet located at least
10 feet from any moving part of the gate (see diagram below). Never install any control device where a
user will be tempted to reach through the gate to activate the gate opener.
5. Do not activate your gate opener unless you can see it and can determine that its area of travel is clear of
people, pets, or other obstructions. Watch the gate through its entire movement.
6. Secure outdoor or easily accessed gate opener controls in order to prohibit unauthorized use of the gate.

III. After Installation
1. Attach the warning signs (included) to each side of the gate to alert the public of auto matic gate
operation. It is your responsibility to post warning signs on both sides of your gate. If any of these signs
or warning decals become damaged, illegible or missing, replace them immediately. Contact GTO for
free replacements.
2. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should
be in contact with an activated gate when it is moving or stationary.
3. Do not attempt to drive into the gate area while the gate is moving; wait until the gate comes to a
complete stop.
4. Do not attempt to "beat the gate" while the gate is closing. This is extremely dangerous.
5. Do not allow children or pets near your gate. Never let children operate or play with gate controls.
Keep the remote controls away from children and unauthorized users; store controls where children and
unauthorized users do not have access to them.
6. KEEP GATE AND GATE OPENER PROPERLY MAINTAINED. Always turn power to opener OFF before
performing any maintenance. Regularly grease the gate hinges. Clean the push-pull tube with a soft, dry
cloth and apply silicone spray to it at least once per month.
7. To operate this equipment safely, YOU must know how to disconnect the opener for manual gate
operation (see page 1). If you have read the instructions and still do not understand how to disconnect
the opener, contact the GTO Service Department.
8. Disconnect the opener ONLY when the power is TURNED OFF and the gate is NOT moving.
9. Make arrangements with local fire and law enforcement for emergency access.
10. Distribute and discuss copies of the IMPORTANT SAFETY INSTRUCTIONS section of this manual with
all persons authorized to use your gate.
11. IMPORTANT: Save these safety instructions. Make sure everyone who
is using or will be around the gate and gate opener are aware of the
dangers associated with automated gates. In the event you sell the
property with the gate opener or sell the gate opener, provide a copy
of these safety instructions to the new owner.
Should you lose or misplace this manual, a copy can be obtained by
downloading one from the Mighty Mule® web site (www.mightymule.
com), by contacting GTO, Inc., at 3121 Hartsfield Road, Tallahassee,
Florida 32303 or by calling 1-800-543-4283 and requesting a duplicate

ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Mighty Mule® E-Z Gate Opener is designed to stop and reverse within 2 seconds when the
gate comes in contact with an obstruction. Additionally, these openers are equipped with an audio
entrapment alarm which will activate if the unit obstructs twice while opening or closing. This alarm
will sound for a period of 5 minutes, or until the opener receives an intended signal from a hard wired
entry/exit source (e.g. push button control or keypad) and the gate returns to a fully open or fully closed
position. Turning the power switch on the control box OFF and back ON will also deactivate the alarm.
Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.
Secondary Means of Protection Against
Entrapment
As specified by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have
an inherent entrapment sensing system, and shall have provisions for, or be supplied with, at least one
independent secondary means to protect against entrapment. The Mighty Mule® utilizes Type A, an
inherent (i.e., built-in) entrapment sensing system as the primary type of entrapment protection. Also, the
Mighty Mule® has provisions for the connection of Type B2 protection to be used as the secondary type
of entrapment protection, if desired.
1. For gate openers utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL
325 (51.8.4 [i]):
A. One or more contact sensors shall be located at the leading edge, bottom edge, and post edge,
both inside and outside of a vehicular swing gate system.
B. A hard wired contact sensor shall be located and its wiring arranged so that the communication
between the sensor and the gate opener is not subjected to mechanical damage.
C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate
opener for entrapment protection functions shall be located where the transmission of the signals are
not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless
contact sensor shall function under the intended end-use conditions.

Mighty Mule 202
Install Warning Signs
Entrapment Protection
GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to
prevent bodily injury in some circumstances. For this reason, safety devices such as safety edge
sensors (or photoelectric sensors), which stop and reverse gate direction upon sensing an obstruction,
are suggested for enhanced protection against entrapment.
Required Safety Precautions for Gates
Warning Signs
The warning signs (at right) must
be installed on both sides of the
gate (see page 7 for details).
Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule®
E-Z Gate Opener. Furthermore, a walk-through gate must be installed if pedestrian traffic is expected near
the vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales
Department) for controlled access.
1. KEEP CLEAR! Gate may move at any time.
2. Do not allow children to operate gate or
play in gate area.
3. This gate is for vehicles only. Pedestrians
must use a separate entrance.

Preparation of the Gate
The gate must be plumb, level, and swing freely
on its hinges. Wheels must not be attached to
the gate. The gate must move throughout its arc
without binding or dragging on the ground.
Note that gates over 250 lb.. should have ball
bearing hinges with grease fittings.
The fence post should be no larger than 6" in
diameter and must be secured in the ground

when the opener is activated. We recommend
you position the opener near the centerline
of the gate to keep the gate from twisting and
nFYJOHBOEUPBWPJECBDLTQMBTIGSPNSBJOXBUFS
The addition of a horizontal or vertical cross
member (if one is not already in place) to provide
a stable area for mounting the gate bracket is
also important.
32 foot power cable allows the
control board to control the
SECOND gate openers (run in
PVC conduit)
You will need to trench across the
driveway in order to lay conduit for
the second opener power cable.

Be sure the position of the gate opener and brackets allows for 1 inch of
clearance between the gate and the opener in both the open and closed
position, at the same time maintaining a maximum distance of 13 inches
from the end of the opener arm to the gate bracket with the gate in the
closed position.

Installation of the FIRST Gate Opener
IMPORTANT: The gate on the side where the control box is to be mounted will be the FIRST gate
opener to install.
The position of the post bracket determines the leverage and efficiency of the opener. The post bracket
position also sets the clearance between the opener and gate in the open and closed positions.
The post bracket works well for installations
on round and square fence posts. Because
the post bracket carries the entire thrust of
the active opener, bolts that completely
penetrate the fence post must be used.
On wooden posts, place a metal plate or
washer (not supplied) between the nuts and
the fence post to prevent the thrust of the
opener from pulling the bolts and washers
out of the wood.
NOTE: A fence post smaller than 6" in
diameter or 6" square should be made of
metal instead of wood so that it will remain
stable while the opener is moving the gate.

adjust the post bracket assembly and gate bracket until the opener is level. While holding the opener level,
use C-clamps to temporarily keep the post bracket assembly and gate bracket in their respective positions
on the fence post and gate.
Step 1
Insert the 3/8" x 11/2"
bolt through the center
hole of the post brackets
and post pivot bracket
as shown. Fasten a 3/8"
washer and 3/8" lock nut
on the end of the bolt.
DO NOT overtighten the
lock nut because the
post pivot bracket will
have to be adjusted later.
Step 2
Attach post bracket assembly to the rear mount of the opener with a clevis pin and a 3/8" washer. Secure
the clevis pin with a hairpin clip. Attach gate bracket to the front mount of the opener with a clevis pin and a
3/8" bushing. Secure the clevis pin with a hairpin clip

After verifying that you have the best position for the post pivot bracket in the open position, insert the
5/16" x 1-1/2" bolt through the aligned holes of the post bracket and post pivot bracket to hold it in place.
Remove the clevis pin from the front mount and while supporting the gate opener, swing the gate and gate
opener to the closed position. With the gate and gate opener in the closed position check the clearance
and be sure that the gate opener is not binding at the post pivot bracket.

bolt and readjust the pivot bracket until you can achieve these important clearances and distance.
With the post pivot bracket in the optimum position for clearance and freedom of movement, reattach
the opener to the gate bracket in the open position and recheck the gate opener level and make sure the
brackets are clamped securely.
IMPORTANT: While determining the mounting point for the post pivot bracket assembly, be sure that the
position allows for minimum 1 inch of clearance between the gate and the opener in both the open and
closed positions, as well as maintaining the maximum 13" distance explained in the gate installation overview
earlier. This position will give the opener the most efficient leverage point for opening and closing the gate
and more importantly provides the least possible pinch area.
TIP: Turning the pivot bracket over gives
more hole alignment options for the post
pivot bracket assembly. You can also move
the entire post pivot bracket assembly to
different positions on the gate post to help
achieve the proper clearances.

Step 9
Attach the opener to the securely bolted post bracket assembly and gate bracket using clevis pins, bushings,
and hairpin clips, or optional Pin Locks (see Accessory Catalog). Verify that the opener is level and adjust the
post bracket assembly if necessary.
Install the SECOND gate opener and hardware on the SECOND gate following the same procedures as the
FIRST gate opener and hardware (Step 1 - Step 9).
The power cable for the Second Opener should be run in PVC conduit under te driveway to protect it from
damage due to lawnmowers, heavy equipment and other damaging forces. It will also make it simple to
remove or replace the Second Opener if it is ever damaged.
NEVER SPLICE opener arm POWER CABLES. This will cause performance problems and may damage the
opener.

Installation of the Closed Position Stops
The Mighty Mule® Gate Opener firmly holds the gate in the closed position using the
positive stop plate. The positive stop helps stabilize the gate leaf in the closed position.
To further enhance the stability and security of your gate, install the optional
Mighty Mule® Automatic Gate Lock (see Accessory Catalog).
Step 1
Detach the gate operators from the gates
and move the gates to their closed position
(Illustration A). Using appropriate hardware
for your type of gate (U-bolts for tube or chain
link; screw or bolts for wood or metal - this
hardware is not included) attach the closed
position stop plate (horizontally) about mid
height on the FIRST gate frame. Do not
tighten it completely at this time. Slide the
stop plate toward the frame of the SECOND
gate leaf until they touch (Illustration B). Once
you have moved the stop plate to the correct
position, tighten its hardware completely.

damage the control board.
If you are using the transformer included with the Mighty
Mule 202 to charge the opener battery, skip this section
and go to "CONNECTING BATTERY".
Strip 3/16" off the ends of the low voltage
wire and twist tightly. Attach these
ends to the '14VAC or SOLAR'
terminals located on the terminal block
(see illustration at right). Be certain not
to let the exposed wires touch each
other!
Insert one solar panel wire into a
'14VAC or SOLAR' terminal. Insert
the other solar panel wire into the
remaining '14VAC or SOLAR'
terminal. The wires can be connected
to the '14VAC or SOLAR' terminals
regardless of color.
Tighten set screws against exposed end of
wires. A dab of household petroleum jelly on
each terminal will help prevent corrosion.
NOTE: For multiple panels wire the panels in
parallel as shown in this diagram.

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage,
PVC sheathed wire. This particular gauge enables the transformer to provide an adequate
charge through the control board to the battery at distances up to 500 ft.
DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire
are inadequate for use with your gate opener system.
NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's
ability to carry an adequate current.

Your Mighty Mule 202 has two Limits
1. OPEN Limit setting: (Gate in the OPEN POSITION / FACTORY SET & NOT ADJUSTABLE) The open limit is
when the opener is fully retracted and the gate is in the full open position.
2. CLOSED Limit setting: The CLOSED Limit setting (gate in the CLOSED POSITION). To achieve optimum
closed position, you are required to complete the following STEPS:
Step 1
If not already ON slide the ON/OFF switch on the Control Box to the ON position and make sure the
arms are in the OPEN POSITION (fully retracted).
Step 2
Press and HOLD the 2nd Opener CLOSE button on the control board and be prepared to RELEASE
the button when the gates reached the desired closed position/limit. Use the JOG OPEN and CLOSE
buttons to "fine tune" the gate position if neccessary.
Step 3
Repeat STEP 2 for the 1st Operator
Step 4
NOTE: The opener Push-Pull tubes must be extended more than 7 inches to set limits.
With the gates in in the desired closed positions PRESS and HOLD the SET LIMIT button until the
buzzer and RED Light come on. Then release the button.
Step 5
NOTE: When the control box cover is removed the receiver range is reduced to less than 5 feet.
Press the transmitter button once (within 5 feet of the control board) and allow the gates to fully open.
The alarm will beep once when both gates reach the OPEN LIMIT. This indicates the LIMITS for both
arms are learned and stored in memory
Step 6
Press the transmitter button and allow the gates to fully close to verify that they stop at the desired
positions. Repeat STEPS 2-5 if correction is needed.
Setting the Closed Position Limit
Must have a transmitter that operates the gate. If not see 'Setting Your Personal Transmitter Code' on page 29.

Mighty Mule 202
Stall Force Potentiometer Setting
IMPORTANT: For safety reasons the obstruction set-
ting or Stall Force on the Mighty Mule® control board
comes from the factory set at MIN (minimum). In
many gate installations this setting will
need to be adjusted to overcome the
weight and size of the gates.
The Stall Force potentiometer on the
control board operates like a volume
control on a radio. It controls the
obstruction sensitivity (or the amount
of force the opener will apply to an
obstruction) before it automatically
stops and reverses direction for
approximately two (2) seconds.
Use a small slotted screwdriver to turn the arrow in the center
of the potentiometer. Adjust the sensitivity from the MINIMUM
position where the gate operates without obstructing from its
own weight or the wind conditions in your area.
NOTE: You may need to increase the stall force in cold weath-
er due to increased resistance from gate hinges.
Setting Auto-Close Time
CLOSE TIME (auto close timer): Determines how
long the gate will remain open before it automati-
cally closes. The limits are OFF and
3 - 120 seconds. The factory setting is
OFF.
NOTE: Auto-Close timer is disabled
(gate will not automatically close) if gate
is not in the open limit.
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST
WHEN ADJUSTING OR
SERVICING YOUR AUTOMATIC GATE OPENER!

E. Verify that the transmitter operates the gate.
NOTE: It is NOT necessary to remove the cover of the control box to 'learn' the new transmitter
code, but when the control box cover is removed the receiver range is reduced to less than 5 feet.
2. Set the Transmitter DIP Switches
There are nine (9) transmitter DIP switches; each can be placed in three
different positions (+, 0, –). DO NOT set all the switches in the same
position, such as all +, all 0, or all –. Once the DIP switches have been
set to a personal code, replace and close the access cover.
WARNING: No other adjustments should be made inside the transmitter.
1. Remove the Transmitter Cover
On the back of the transmitter use a small phillips head screw driver
to remove the two screws on the sides of the visor clip and separate
the front cover from the transmitter. With the front cover removed,
the battery and the DIP switches will be exposed. To set a new code,
use a small screwdriver to move the switches.
All GTO transmitters are set to a standard code at the factory and are
ready to operate your Mighty Mule® Gate Opener®. For your safety and
security, however, we strongly recommend that you replace the factory
setting with your own personal code. Follow the directions below:

position), and the opener fully retracted, adjust the post bracket
assembly and gate bracket until the opener is level. While
holding the opener level, use C-clamps to temporarily keep
the post bracket assembly and gate bracket in their respective
positions on the fence post and gate.
Push to Open Installation
Swinging gates MUST NEVER open into public access areas!
"Push-to-Open" gates open out from the property.
Push-to-Open Brackets are required for this type of
installation (see Accessory Catalog). If you have pull-to-open
gates (gate opens into the property), return to page 13;
In a PUSH-TO-OPEN installation the opener is installed while the
gate is in the closed position and the opener fully retracted .

Step 2
After verifying that you have the best
position for the post pivot bracket, insert the
5/16" x 1 3/4" bolt through the aligned holes
of the post bracket and post pivot bracket
and fasten it with the 5/16" washer and nut.
IMPORTANT: If you loosened the clamp on
the post bracket to achieve the optimum
position, tighten it in its new position and
recheck the gate bracket with the gate in
the open position (move the gate bracket
and re-clamp it if necessary).
IMPORTANT: While determining the mounting point for the
post pivot bracket assembly, be sure that the position allows for
minimum 2 inches of clearance between the gate and the opener
in both the open and closed positions, as shown in the diagrams
below. This clearance will give the opener the most efficient
leverage point for opening and closing the gate and more
importantly provides the least possible pinch area.
Mighty Mule 202
31
Step 3
With the gate in the fully closed position and the opener retracted, swing the opener to the gate. Mark
reference points for bolt holes on gate cross member through middle of gate bracket slots. The opener
must be level. (Some vertical adjustment is possible by sliding the post bracket assembly up and down.)
Drill 3/8" holes into the gate cross member as marked. Fasten gate bracket to cross member using (2)
3/8" x 3" bolts, washers, lock washers, and nuts. Attach the opener to the post bracket assembly and gate
bracket using clevis pins, bushings, and hairpins clips.
Step 4
Make sure the control box power switch is OFF. Use small pliers to remove the JUMPER for PUSH-TO-OPEN
applications (shown to the right). Turn power switch ON. The control board is now configured to push the gate
open.
