F 03/26/03 190136_f General Information 1 1 GENERAL INFORMATION The PAT AntiTwo-block System has been designed to warn the crane operator of a two-blocking condition of the crane. If a two-blocking condition is approached, the system will warn the operator by sounding an audible alarm, lighting a warning light and locking out those functions which may aggravate the crane's condition, whenever applicable. NOTE: The term "two-block" is a crane term that refers to a condition when the load handling device comes in contact with the boom head. This condition, if not prevented, may cause the wire rope to break, allowing the load to fall. Either raising the load into the boom head, or telescoping the boom out without paying attention to the hoist line can cause a "two- block" condition. 2 WARNINGS The PAT Anti-Two- Block System is an operational aid, which warns a crane operator of approaching two-block conditions, which could cause damage to equipment and personal injury. This device is not, and must not be a substitute for good, sound operator judgment, experience and use of accepted safe crane operating procedures. The responsibility for the safe operation of the crane remains with the crane operator who must ensure that all warnings and instructions supplied are fully understood and observed. Prior to operating the crane, the operator must carefully and thoroughly read and understand the information in this manual to ensure that the operation and limitations of the system and the crane are known. Proper functioning is dependent upon proper daily inspection and observations of the operating instructions set forth in this manual. Caution: changes or modifications to this product which are not expressly approved by PAT could void the user's authority to operate the equipment. PAT Rev. F 03/26/03 190136_f 2 Installation, Operators & Calibration Manual Radio Anti-Two-Block 3 SYSTEM DESCRIPTION The PAT Radio Anti Two Block, RATB, uses state-of-the-art technology. The radio communication electronics were designed cooperatively between PAT and OMNEX controls. OMNEX was chosen because of its established name and proven experience with wireless communications in the construction equipment industry. Our system transmits an OK signal ~ every two seconds on up to three separate channels. This is to ensure accurate and consistent reception of data and to reduce the possibility of unnoticed failure. The separate channels greatly reduce the probability of failure due to external interferences. Unique, serialized transmitter identifiers are used to ensure proper operation even though other cranes are in the area. The PAT RATB is easily configured to communicate with up to two transmitters. Simply by pressing and holding the ID button for five seconds, the receiver can sense the transmitters being used and configure the receiver to listen to only those transmitters. There are no numbers, IDs or codes to remember or write down. The PAT RATB has been designed to be easily and quickly installed. It can be installed in an OEM application in under an hour. The PAT RATB works like our normal Anti-Two-Block. It alerts to an impending two-block condition. This alert can come in the form of an audible alarm and visual LED or with the optional function lockout if the crane is so equipped. The PAT RATB transmitter is modular by design, containing three separate parts, the transmitter, the switch and the battery housing. It was designed so these individual components can be replaced easily and separately. The receiver is mounted into a receiver box, which is water-tight when submerged in up to three feet of water. The receiver box provides the following indications: Power (status), LINK, Low Battery, and A2B. If battery saving measures are used, the battery life will be greater than one year or up to two years, even with transmitting every two seconds. Several power saving methods are incorporated into the design of the electronics as well as the other hardware. The receiver will work with either 12VDC or 24 VDC. It is fused to 1 Amp and protected to 36 VDC. PAT Rev. F 03/26/03 190136_f System Description 3.1 RECEIVER 3 Radio Anti-Two-Block Receiver 3.1.1 LEDs:
1.The POWER LED (Green) 2.The LINK LED (Green) 3.The LOW BATTERY LED (Yellow) 4. The A2B LED (Red) Receiver Box Shows that there is power to the system. Indicates the status of the communication link between the main hoist A2B transmitter and the receiver. Failure of the communication link will turn off the Green LED and turn off the output to the lockout relay. Indicates that the battery of the main transmitter needs to be replaced. Indicates an impending two-block condition of the main hoist. The Red LED will light when the load-
handling device has lifted the A2B weight. This LED will light simultaneously with the engaging of the lock out solenoids (if installed). 3.1.2 The yellow ID button, located in the lower right-hand corner of the receiver board, is used to set the transmitter ID of the transmitter into the receiver. ID button PAT Rev. F 03/26/03 190136_f 4 Installation, Operators & Calibration Manual Radio Anti-Two-Block 3.2 TRANSMITTER / SWITCH The transmitter and battery housing are made of a special plastic that resists impact and will not become brittle even in low temperatures. 3.2.1 Transmitter LED The transmitter has an LED on the bottom for diagnostics. The LED should be on when in a two-block condition or when the weight is lifted. The LED will flash rapidly during a 2-block condition and will stop flashing after the switch is in a two-block condition for more than 15 seconds. The LED will flash randomly approximately every 2 seconds when the switch is transmitting. When in sleep mode, the LED will not flash. 3.2.2 Storage of the A2B transmitter for Travel The weight should remove from the switch when traveling to extend battery life. The system is in permanent lockout and the system will not function until the chain is unhooked. To use the feature, attach any part of the chain into the hook. When it is desired to use the switch again, simply unhook the chain to allow the switch to close. The weight and chain must be hung from the switch and/or the chain must be unhooked before the crane is operated. PAT Rev. F 03/26/03 190136_f Installation 5 INSTALLATION 4 4.1 TRANSMITTER/SWITCH Install the standoff to the boom head using a 5/16x3/4 HEX bolt. The hole pattern for the standoff is the same as that of conventional PAT A2B switches. In most cases the standoff can be mounted in the same location as the conventional switch. If not replacing an existing switch, the proper location would be one that allows the switch to rotate freely without being obstructed by any part of the boom head. It should be mounted close to the dead end mounting gusset. The switch should normally be mounted on the cab side of the crane. For jib installations, locate the switch close to the jib head. Remove the lynch pin from the standoff. Slide the A2B switch onto the standoff. Replace the lynch pin into the standoff. Install the weight and chain onto the A2B switch. PAT Rev.

Operation Inspection and Calibration Verification. During the normal operation of the system the LINK and POWER LEDs should be on. POWER LED The POWER LED shows that the OEM module is getting power from the crane. The receiver is on any time the crane is operating and supplying power to the system. LINK LED The LINK LED indicates the status of communication of the transmitter(s). During normal operation of the system, the LED will be on. The LED is off when there is an interruption in the transmission. The system should not be operated if the LINK LED is not lit. LOW BATTERY LED The low battery indicator will light indicating that you have a limited time to operate before the system goes dead. When the battery level is to the point that it is too low to operate, the system will stop functioning. Use any off-the-shelf alkaline C-cells; Duracell, Eveready, etc. A2B ALARM LED Indicates an impending two-block condition of the main hoist. The Red LED will light when the load-
handling device has lifted the A2B weight. This LED will light simultaneously with the engaging of the lock out solenoids (if installed). Test the electronics Cycle the power to the system, each LED on the receiver will light for 2 seconds when the system is powered. All of the indicator lights must come on or the system is not functioning properly. If any light does not function, do not use the system until it has been repaired. PAT Rev. F 03/26/03 190136_f System Testing 9 7 SYSTEM TESTING To test the electronics:
Each LED on the receiver will light for 2 seconds when the system is powered. All of the indicator lights must come on or the system is not functioning properly. If any light does not function, do not use the system until it has been repaired. Following the successful testing, the LINK LED should come on. If the LEDs do not come on, there is an error in the transmission. Do not use the system until it has been repaired or replaced. (Refer Troubleshooting section.) To test the hoist limiting:
After the electrical connections have been checked to ensure that the system is properly connected for the crane configuration, the following checks must be made:
The following tests must be performed with care to prevent damage to the machine or injury to personnel. Proper functioning of the system requires successful completion of these tests before operating the machine. Check the anti two-block switches and weights for free movement. If the operator cannot see the load-handling device approaching the boom nose, an assistant (signal person) must watch the load-handling device. The operator must be prepared to stop the machine immediately should the RATB system not function properly. This is indicated by lighting the red warning light, sounding the audible alarm and locking the following crane movements: hoist up, telescope out and boom down. Manually lift the weight attached to the anti two-block switches. When the weight is lifted, the audible alarm should sound, the anti two-block alarm light should light. PAT Rev. F 03/26/03 190136_f Installation, Operators & Calibration Manual 10 With optional lockout installed the following additional tests must be performed:
Slowly raise the main boom load-handling device to create a potential two-block condition. When the load-handling device lifts the weight, the audible alarm should sound, the anti two- block alarm light should light and the motion of the load-handling device should be stopped. Lower the load-
handling device slightly to eliminate this condition. Radio Anti-Two-Block Slowly lower the boom to create a potential two-block condition. When the load-handling device lifts the weight, the audible alarm should sound, the anti two-block alarm light should light and the boom lowering function should be stopped. Lower the load-handling device slightly to eliminate this condition. Slowly extend (telescope) the boom to create a potential two-block condition. When the load-
handling device lifts the weight, the audible alarm should sound, the anti two-block alarm light should light and the boom telescope out function should be stopped. Lower the load-handling device slightly to eliminate this condition. If the light and audible alarm does not function as described and the crane movements are not stopped, the system is not working properly. The malfunction must be corrected before operating the crane. If the crane is equipped with a second transmitter, repeat the test on the second transmitter. PAT Rev.
