1. INSTALLATION, ADJUSTMENT AND MAINTENANCE

1.1 CR-25E Installation Instructions (Reference Drawing: 0025-0050-A)

NOTE: Failure to install your barrier properly could cause damage to the

operating mechanism.

1. Read the instructions and review the drawings thoroughly. If you do not understand any part of these instructions, please contact the manufacturer.

2. Check the anchor bolt locations and prepare the foundation for the barrier. Set the barrier operator and be sure to seal the bottom with duct seal. Housing must be level. Anchor bolts must be tightened evenly.

3. Make sure the local power supply for the motor and control circuit are correct. *Reference the enclosed electrical drawing in the back of the handbook.

IMPORTANT: All conduit must be sealed and the housing grounded.

4. Using the hand crank, turn the drive crank 45 degrees noting rotation of the drive crank should be clockwise.

5. Open main disconnect switch (S1) and connect the power. Connect the control circuit if separate. If power is supplied from the motor circuit, check the connections at the terminals.

NOTE: At this point in the installation, no counterweights or arms should

have been installed.

6. "Bump" test barrier operator for correct motor rotation.

NOTE: The drive cranks should rotate upwards toward roadway to raise

barrier arm (viewing barrier operator from either drive crank side of the housing).

7. Run barrier operator (without arms or counterweights) through several complete cycles. Leave the barrier operator in the closed to traffic position and open the main disconnect switch.

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. 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.

9. 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. With the arm in the down position, install the allotted amount of counterweights (Item #3) on the side arm tube assembly. Tighten bolts securely.

11. 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.

1.11 Field Balancing Instructions

IMPORTANT: EVERY BARRIER IS BALANCED AT THE FACTORY BEFORE IT IS SHIPPED. IF ANY ADDITIONS OR CHANGES ARE MADE TO THE BARRIER ARM IN THE FIELD, THE BARRIER MAY REQUIRE RE-BALANCING. AN UNBALANCED ARM MAY DAMAGE THE OPERATOR.

If any additions or changes are made to the barrier, the following guidelines will help you determine what changes, if any, need to be made to the barrier balance:

1. Make the desired changes to the barrier arm.

2. Secure the tip end of the arm to prevent injury or accident.

3. Disconnect the connecting rod which runs between the upper and lower cranks,

this will free the arm to be balanced.

Calculating Counterweight Requirements

1. Disconnect arm drive by removing top connecting rod bolts located on each side of

the operator.

2. Mark any place on the barrier arm and attach a weighing scale to the arm at that

point.

3. Measure how much weight, in pounds, it takes to start raising the barrier arm. (arm

lbs.)

4. Measure, in inches, the distance from the weight point to the center of the pivot point

(arm distance).

5. Measure, in inches, the distance from center of pivot point to center of

counterweight (counterweight distance).

6. Follow this formula to get the proper amount of counterweight to add to barrier.

arm lbs. x arm dist. cw dist.

COUNTERWEIGHT SIZES

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.

Installation & Operations Manual CR-25E Cable Beam Barrier Installation, Adjustment & Maintenance 16 of 31

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.

Installation & Operations Manual CR-25E Cable Beam Barrier Installation, Adjustment & Maintenance 17 of 31

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.

Installation & Operations Manual CR-25E Cable Beam Barrier Installation, Adjustment & Maintenance 18 of 31

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.
