Installation & Operations Manual
CR-25E Cable Beam Barrier
Installation, Adjustment & Maintenance
5 of 31
NOTE:
This barrier has been completely assembled and test run through 24
complete cycles under full power at the factory. If satisfactory
operation is not displayed in step #7, recheck all electrical connections
carefully. CONSULT FACTORY IF PROBLEM IS NOT FOUND.
8.
9.
Remove side arm tube cover plate (Item #2). Locate pillow block bearings (Item
#12). Do not tighten set screws. Now center assembly with housing. When
assembly is correctly centered, tighten bearing set screws.
Insert arm, with endlock intact, into the main arm tube base. Push tube far
enough to make the cable, connections at the pivot. After cables have been
securely bolted to the pivot mechanism, extend arm so that the endlock saddles
satisfactorily over the anchor assembly (on the bollard). Slide lock coller into
place and tighten allen bolts.
NOTE 6:
If endlock fails to line up properly, loosen bearing bolts and rotate
laterally. Re-tighten bolts. Now tighten arm base bolts securely.
Replace side arm tube cover plate (tighten bolts securely).
10.
11.
With the arm in the down position, install the allotted amount of counterweights
(Item #3) on the side arm tube assembly. Tighten bolts securely.
Close the main disconnect switch (S1) and operate the control circuit. If all
connections are made correct, barrier arm will operate to fully up or fully down.
The limit switch will automatically stop the motor at the extreme 90-degree
movement of the arm.
12.
With the barrier in the lowered position, check endlock mechanism for any type
of hindrance with bollard post and adjust accordingly if required.
IMPORTANT:
IF THREE PHASE POWERE CONNECTIONS TO THE
MOTOR ARE REVERSED, THE LIMIT SWITCH WILL
AUTOMATICALLY DISCONNECT THE MOTOR WHEN THE
DRIVE CRANK HAS ROTATED ABOUT 30 DEGREES IN THE
INCORRECT DIRECTION, DEPENDING ON THE POSITION OF
THE CONTROLS, i.e., UP OR DOWN. DRIVE CRANK MUST
THEN ROTATE BACK TO ORIGINAL (VERTICAL) POSITION
USING HANDCRANK, IN ORDER TO RESET BARRIER.
If this problem occurs, phase must be reversed. The limit switch has
been set at the factory and should NOT REQUIRE ADJUSTMENT.
Arm should be raised or lowered by lengthening or shortening of the
connecting rod not by adjustment of the limit switch cams.

1.7 Recommended Replacement Oils for CR-25E
Direct replacement of oils is very complicated and should be considered carefully when
doing so. The following oils are recommended by the manufacturer of the transmissions
on the warning gates and barriers.
The multi-grade Mobil SHC 629 synthetic oil is the manufacturers first choice. If this oil
is not available, Exxon Terrestic SHP 150 can be used as a direct replacement. The
temperature range is -30°F to 165°F.
If neither of the two above mentioned oils is available, almost any ISO Grade 150 or
AGMA Lubricant #4 with a pour point of -40°F or less & a viscosity of approx. 726
(SUS@100°F) is acceptable.
The following grease is recommended by the manufacturer of the flange type bearings
used on both the warning gates and barriers.
Texaco Marfax or Texaco Starplex grease is the manufacturers first choice. If this grease
is not available, consult your local supplier for an equivalent.

1.13 Adjusting the Barrier Movement
When installing or maintaining a CR-25 barrier, setting the limit switches and connecting
rod length properly can be confusing at times. The following instructions are intended to
clarify this process. The steps can be broken into two sections, setting crank orientation,
and setting barrier starting and stopping points.
SECTION 1: SETTING THE CRANK ORIENTATION AND ROTATION USING
THE LIMIT SWITCHES
A standard CR-25 barrier operator with 90 degrees of travel is designed so that the barrier
arm accelerates and decelerates smoothly as it pivots. This is achieved through the
lengths of the two crank arms. In order to optimize this “sinusoidal” movement, the
following steps should be followed when installing the operator.

CR-25E Cable Beam Barrier
Installation, Adjustment & Maintenance

1) Determine the direction of rotation of the cranks. In a standard installation, the cranks
pivot toward the motor, and the roadway.
The limit switch cams rotate the same direction that the pivot rotates. Cam 1 is always
the raise stop, Cam 2 is always the lower stop, Cam 3 generally controls the arm lights if
there are any.
IMPORTANT: Always power down at the main switch before adjusting the limit
switches.
2) Manually rotate the barrier into its fully open to traffic (raised) position by inserting
the manual crank onto the shaft extending from the top of the motor and turning it
until the barrier reaches the desired position.
Note: At fully open, the connecting rods should be parallel with the sides of the operator
and with the cranks. The cranks should be pointing straight up.
3) With an allen wrench loosen the limit switch cams just enough so that they will turn,
but not so much that they are loose.
4) Rotate Cam 1 until the limit switch follower just falls off of the edge of the cam. Keep
the direction of rotation of the cam in mind as you set it to ensure that when the barrier
rotates, the limit switch follower will move back onto the cam.

5) Manually rotate the barrier into its fully closed to traffic position.
Note: At fully closed, the lower drive crank should have rotated through 180 degrees, and
should be pointing straight down. The connecting rods should be parallel with the sides
of the housing and the cranks.
6) Rotate Cam 2 until the limit switch follower just falls off of the edge of the cam. Keep
the direction of rotation of the cam in mind as you set it to ensure that when the barrier
rotates, the limit switch follower will move back onto the cam.
7) Re-apply power and run the barrier open and closed. If the cams require more
adjustment it is important to disconnect power before moving the limit switch cams.
Be sure to re-tighten the limit switch cams once they have been properly set.
NOTE: At this point in the adjustment, the crank orientation is more important than the
barrier position. At the fully open and fully closed positions, the connecting rods should
be parallel with the sides of the housing, and the drive cranks should point directly up or
directly down.
STEP TWO: ADJUSTING THE STOPPING AND STARTING POINTS OF THE
BARRIER ARM
If the starting and stopping points of the barrier arm need to be adjusted, this will be done
using the connecting rods. This should only be done if the cranks and connecting rods
positions are correct as described above.

8) With the barrier in the fully raised or lowered position, loosen the lock nuts on the
connecting rods and turn the rods to increase or decrease their length. Adjust the rods
until the barrier arm is in the desired position.
NOTE: Adjusting the connecting rods changes both the raised and lowered position by
the same amount.
9) Run the barrier through several cycles to ensure proper starting and stopping points.
10) If the barrier panel travels slightly too far in either the open or closed direction, this
can be adjusted using the limit switches. It is important to note that adjusting the limit
switch at this point will stop the barrier arm before it has fully decelerated.

Installation & Operations Manual
CR-25E Cable Beam Barrier
Specifications
20 of 31
The main arm shaft will be mounted in heavy duty ball bearings. The main arm shaft will
be not less than 2 inches in diameter. Shaft material will be ASTM A311 Class B high
strength, stressproof steel.
TRANSMISSION
The transmission will be a fully enclosed, all gear, direct drive unit running in an oil bath.
The drive train will not use belts or chains and will be connected to the arm shaft with a
connecting rod having self-aligning ball ends. The connecting rod will be constructed of
ASTM A311 Class B high strength stressproof steel.
During the opening and closing cycles, the gate arm will begin with zero velocity and
accelerate smoothly reaching maximum velocity at mid-stroke (45 degrees). The arm
will then decelerate smoothly to zero velocity at full stroke (90 degrees) preventing
bounce or whip of the arm. Standard operating time to open or close the gate will be 13
seconds. Consult the factory for other available speeds.
MOTOR
A 110V, 1/2HP Single Phase motor will be supplied. The motor will be of the flange
mounted type, attached to the transmission case with not less than four bolts. The motor
will be of the instant reversing type to permit reversing movement of the arms at any
point of travel. Motor data will appear in the manual.
BRAKING MECHANISM
A solenoid release, automatic motor brake will be furnished as part of the gate drive
mechanism. The brake will automatically release when the handcrank is inserted to
manually operate the gate.
HANDCRANK
A handcrank and drill crank will be included with each gate to operate the gate during
power failure. An automatic safety disconnect switch will automatically break the
control circuit power when the handcrank is inserted to allow for manual operation.
LIMIT SWITCH
The gate limit switch will be a unit assembly containing eight individual switches having
one set of normally open and one set of normally closed contacts each. Contacts will be
totally enclosed and will have U.L. rating of not less than 15 amperes at 220 volts AC.
Limit switch will be readily accessible and easily replaced with normal hand tools. Each
individual switch will be controlled by an independent cam, which will be adjustable with
a hex socket cap screw. The limit switch body, shafts and cams will be of corrosion
resistant non-ferrous materials.

SAFETY SWITCHES, TERMINAL BLOCKS AND WIRING
To protect operating and maintenance personnel from injury during service or
installation, a manual disconnect switch will be furnished, installed and fully wired in the
main motor leads. Automatic disconnect switches will be arranged to break the control
circuit when either door is opened. Pressure type terminal blocks will be provided and
installed inside the housing on the roadway side. All control wires will terminate on
these blocks. Each terminal will be clearly labeled and all conductors will be color coded
and/or numbered. The wiring diagram will reflect such colors or numbers. A GFI
receptacle will be supplied in the gate housing. No conductor will be smaller than #16
AWG stranded. Each housing will contain a laminated electrical schematic secured to
the inside of the housing for reference by service personnel.
ENERGY ABSORPTION CABLES
A 7/8-inch diameter galvanized, double-extra improved plow steel 6 x 9 IWRC
(independent wire rope center) wire rope will provide the primary vehicle restraint
capability of the barrier. The cable will have closed, cad-plated swage sockets on each
end. Both ends of the cable will be anchored securely at the operator end of the beam
doubling the cable. The cable assembly will be enclosed inside the arm and will form a
loop at the end of the beam arm.
CABLE ANCHORING SYSTEM
The cable assembly will be designed to securely engage an anchor post at the arm end on
impact. The engaged assembly will be designed to anchor the cable assembly at each end
of the beam at all times when the arm is in the closed position to withstand collision
loads.
Engagement of the anchoring assemblies at each end will not rely upon any electrical,
hydraulic, magnetic or other powered devices. A clevis mounted on the end of the crash
beam will be designed to securely and passively engage and lock itself to the bollard
upon vehicle impact with the beam.
QUALITY ASSURANCE
Manufacturer of the traffic control gate operator will have a minimum of five years
experience in the manufacture of industrial gate operators and barriers, and will make
available replacement parts for 10 years. All gates are individually inspected at time of
final assembly and test. Each gate will be tagged "ACCEPTED" upon completion of
inspection and “Certification of Testing” will be supplied in the handbook for validation
of meeting internal Quality Assurance standards.
