General Information

1 GENERAL INFORMATION

The PRS 40 EZ System has been designed to provide indication from various types of sensors, i.e. A2B, Load, Wind and Angle. The A2B system will 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, flashing the backlit LCD and locking out those functions which may aggravate the crane's condition, whenever applicable. If the system is set up for load, angle or wind, limits can be set by the user. When these limits are exceeded the system will warn the operator by sounding an audible alarm, flashing the backlit LCD and de-energize the lockout relay. The system relay can be connected to the cranes lockout system. If so, the system will lock out when exceeding any of the user limits.

NOTE:

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.

The term "two-block" is a crane term that refers to a condition when the load handling device

2 WARNINGS

The PRS 40 EZ 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.

The system can only work correctly, if all sensors/transmitters have been properly set. For correct setup, the operator has to answer thoroughly and correctly all questions asked during the setup procedure in accordance with the real rigging state of the crane. To prevent material damage and serious or even fatal accidents, the correct adjustment of the system has to be ensured before starting the crane operation.

Always refer to operational instructions and load charts provided by the crane manufacturer for specific crane operation and load limits.

Operator’s / Service Manual, PRS 40 EZ

3 FEATURES

4 SYSTEM DESCRIPTION

4.1 CONSOLE

The console has 2 functions:

• Accepts inputs from the crane operator (reeving, limits and setup)

• Displays important data and information from the sensors

The operator’s console should be mounted in the operator’s field of vision.

4.1.1 Liquid Crystal Display

The Liquid Crystal Display (LCD) used in the PRS 40 EZ console is a wide temperature-range graphic display with transflective characteristics that give it a high visibility in sunlight and during backlit night operation. Due to the nature of any LCD, it works on the principle of polarization of light. It should be noted that dual polarizations that are at a certain angle to each other can reduce the amount of light up to completely eliminating it if that angle becomes perpendicular. This can have significance if the operator is wearing polarized sunglasses that happen to be perpendicularly polarized in relation to the LCD’s polarization. In this rare case, the operator has to work without sunglasses or find different sunglasses that do not have this characteristic, in order to avoid having the visibility of the display impaired.

The LCD contains an automatic temperature compensation that will adjust the LCD’s contrast according to the surrounding temperature.

Operator’s / Service Manual, PRS 40 EZ

Since button C can deactivate the lockout function of the system, the following instructions must be obeyed:

• The by-pass function shall be used with discretion, as unwarranted use of it to override

the control lever lockout system can result in harm to the crane and danger to property and persons.

• Never use the by-pass function to either overload or operate the crane in a non-

permissible range.

4.2 OPERATION

Upon switching on crane ignition switch, the system starts with an automatic test of the system, of lamps and audible alarm. During the test, the LCD shows the console and system software version. The PRS 40 EZ setup procedure allows the operator to input the sensors being used and the limits for the sensors. The operator must complete the setup procedure for each sensor.

BOOM.

Angle sensor, transmitter, and mounting plate.

The angle sensor will be mounted on the side of boom so as the boom angle changes, the angle sensor can rotate as shown in the 0°(left) and 90° (above) positions.

General information

The angle sensor total range is approximately 105° and the zero point is adjustable in the software in the angle calibration menu. With no software adjustment, the angle range will allow a -15° to 90° range, but if the angle sensor is zeroed at -5° (-5° becomes 0°) your angle range will be -10° to 95°. Therefore, when affixing the mounting plate to the boom, make sure you will be able to get your desired angle range for your application.

Angle

1. Locate an appropriated flat surface area on the boom base section or luffing jib root section. Avoid the installation close to moving parts or parts that could interfere during boom hoist up and down. Lower the boom into position that will allow you to safely install the angle sensor.

Notes: The antenna must point down and not up. Do not install angle sensor on hot mounting plate, temperatures greater than 125°F (52°C) this could damage the angle sensor and/or transmitter.

2. Measure the boom angle by using a digital inclinometer (i.e. smart level) at the area selected in step 1. Align the mounting plate as defined be the decal or so the mounting holes pointing down as shown in the pictures above. Affix the mounting plate onto the area. Clean, prime, and paint the mounting plate if necessary.

3. Remove the angle sensor cover by loosen the four screws in the cover. Check the gasket to insure it is not damaged. Remove the batteries. Align the 4 holes with the mounting plate threaded holes and screw the angle sensor onto the mounting plate by using the four screws supplied in the kit. Attach the antenna to the connector by carefully rotating the antenna clockwise

4. On the console, setup the sensor by using the menu selection: MENU SETUP/SENSORS/ANGLE 1 or 2. In the setup process you will be asked to insert the batteries while the receiver searches for the transmitter. Install batteries correctly as shown on the label in the battery compartment. When the sensor has been found, confirm the angle sensor has been installed. Return angle sensor cover and tighten the four cover screws carefully.

5. On the console, calibrate the angle by using the menu selection: MENU SETUP/SENSORS/ANGLE (1 or 2 as defined above)/ZERO POINT. After making this selection, measure the boom angle by using a digital inclinometer (i.e. smart level), scroll to the correct angle and press OK. The calibration and set up of the sensor is now complete.

6. Check the angle of the main boom at 0°, 40°, 60°, and 70° and compare it with the measure value. It should be ±1°. If it is incorrect, repeat step 5, calibrate the angle sensor again, and verify the actual angle and/or use a different/higher angle (50°) to scroll to and match the angle.

Removal and Storage of the Anti Two-Block Retainer Procedure (see Fig. 3 and 4):

1. Pull the cable out of the switch (1) and bend back parallel to the boom and hold (2).

2. Move the retainer down (3) and then left (4) to remove it from the Anti Two-Block switch. Release the cable.

3. For storage slide the retainer from right side (5) over the Anti Two-Block switch until the clips (A) lock into the holes (B).

Fig. 3: Removal of the Anti Two-Block Retainer Fig. 4: Retainer in Storage Position

After the electrical connections have been checked to insure that the system is properly connected for the crane configuration, the following checks shall be made:

1. Check the electrical wiring connecting the various parts of the system for physical damage.

2. Check the anti two-block switches and weights for free movement.

(WIRED APPLICATION)

Operator’s / Service Manual, PRS 40 EZ

The following tests shall 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.

If the operator cannot see the load-handling device approaching the boom nose, he shall have an assistant (signal person) watch the load-handling device. The operator shall be prepared to stop the machine immediately should the system not function properly as indicated by flashing the warning symbol, sounding the audible alarm and locking the crane movements, hoist up, telescope out and boom down. ( if lockout is installed)

Check the anti two-block alarm by performing one of the following tests:

a. By manually lifting the weight attached to the anti two-block switches. When the weight is lifted,

the audible alarm should sound, the anti two-block alarm display should flash.

b. 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 display should flash and the motion of the load-handling device should be stopped. Lower the load-handling device slightly to eliminate this condition.

c. 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 display should flash and the boom lowering function should be stopped. Lower the load-handling device slightly to eliminate this condition.

If the A2B warning symbol fails to flash and audible alarm does not function as described and the crane movements are not stopped, the system is not working properly. The malfunction shall be corrected before operating the crane.

5. If the crane is equipped with a boom extension, repeat the test procedure for the boom extension anti two-block switch.

A2B

6.1.2 A2B limit

When the A2B limit is exceeded, the relay will disengage. The display will show A2B XX and the red LED will light. The audible alarm will sound. The limit for the A2B is fixed by the chain length and can not be altered.

The transmitter and battery housing are made of a special polymer that resists damage from impact and will not become brittle even in low temperatures.

LED

Operator’s / Service Manual, PRS 40 EZ

6.1.3.B 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. When the transmitter is power up (batteries removed and replaced) the transmitter LED will be on for 1 second to indicate the transmitter is setup for an A2B switch.

6.1.3.C Travel position (optional)

Designed into the transmitter plate is a small hole into which a hook can be installed. This can be used to fasten the chain. This hook is used to open the switch and put it into a permanent 2-block condition. This serves 2 functions.

1. It extends battery life.

2. It prevents the lockouts and alarms from engaging and disengaging due to bounce while traveling.

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 chain must be unhooked before the crane is operated.

6.1.3.D Transmitter/Switch installation

Install the standoff to the boom head using 2 5/16x3/4” HEX bolts. 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.

A2B

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.

LOADCELL

8 LOADCELL

8.1.1 Operation

In order to use the loadcell, the loadcell must first be installed into the system. See the section on loadcell setup. When set up with a load cell, the last selected display and configuration will be shown and must only be confirmed if that configuration setup equals the crane’s actual configuration. Otherwise the reeving must be changed to match the current configuration.

The load cell can be installed into a single part line configuration or into a multipart line configuration. When a multiple parts are used, the system multiplies the force from the load cell by the parts of line selected on the console. This is why it is imperative that the correct parts of line (reeving) is selected on the console.

The correct setting of the reeving is of utmost importance for the proper functioning of the system. Therefore, only operators who are thoroughly familiar with the operation of the system should perform the setting of the system. The system will only measure the load on hook and will not measure the effect of any other attachments.

Reeving

To view the on hook load display, the correct reeving must be set.

Enter Setup screen. Select Reeving and press

LOADCELL

8.1.3 Installation

The load cell is installed at the dead end of the wire rope that is being used to lift the load. Use the appropriate pins for the type and size of socket, block or ball that is being used. Note: The pin size should have been specified when ordered and should match the existing pin diameter. Ensure that the correct pin used is rated for the maximum line pull capacity. For the 7.5 ton load cell, install the pin so the pin head on the antenna side. The pin diameter, jaw thickness and jaw opening used to connect to the load cell will effect position of the antenna. There is 90° fitting for the antenna P/N 031-300-050535 maybe necessary in some cases. Ensure all safety pins are installed properly with washers and bushing to fit the hole diameter and pin length.

7.5 ton Installation

Install the plate using the 2-1/4” pin so the pin head on the antenna side. The plates have a rest button installed to prevent the plates from striking the transmitter on the side of the load cell.

8.1.5.A ACCURACY AND TEST REQUIREMENTS

Check the load display by lifting a load of known weight. The accuracy of the load indication shall be within the tolerance of SAE J376, refer to complete SAE standard before testing.

Accuracy

The accuracy of the load indicating system is to be such that the indicated load is not less than 100% of the actual load, nor more than 110% of the actual load. Where the system cannot meet the accuracy criteria at the lower load range, conspicuous labeling or signaling is to be provided indicating that these accuracy criteria cannot be met.

The weight of the load being lifted and all additional equipment such as blocks, slings, sensors, etc.; also referred to as working load.

Test Requirements

System tests are to be conducted using an appropriate configured crane and specified load rating chart.

For system calibration, three or more test radii or boom angle are to be employed to establish compliance with the accuracy section above. Test loads shall be as near as is practical to minimum, mean, and maximum values within the operating limits.

One of the following test methods or equivalent is to be used:

Known Weight

Test load to be applied by suspending known weights accurate to ± 1%. If the weights of all additional equipment such as blocks, slings, sensors, etc., are included in the test load, the total load is to be known to an accuracy of ± 1%.

Fixed Anchor (Deadman)

Test load to be applied by hoisting against a fixed anchor or deadman equipped with a means for measuring loads accurate to ± 1%. If the weights of all additional equipment such as blocks, slings, sensors, etc., are included in the test load, the total load is to be known to an accuracy of ± 1%.

The system accuracy is to be determined from the following formula:

12.3 TROUBLESHOOTING MOISTURE

The PRS 40 EZ contains electronic components in various locations, such as central unit, sensors, junction boxes etc. These internal components cannot be designed to withstand exposure to moisture over a longer period of time. For this reason, the housings of the components are water protected according to IP 65. If you find water or moisture inside any of the housings, the source for the water ingress has to be detected and corrected to ensure proper operation.

There are two major possibilities for the occurrence of excessive moisture inside an enclosure:

1) Water ingress

2) Condensation

This outline gives instructions for detecting the cause for excessive moisture by using simple troubleshooting methods and how to prevent the moisture ingress from happening again.

12.3.1 Water Ingress

There are 4 possibilities for water to enter an enclosure:

1) Spray Cleaning

2) Missing / Loose Screws

3) Broken Lid

4) Defective Gasket

It is possible to find out the source of water ingress by going through the following steps and ruling out one possibility after the other until the cause is identified:

1) Spray Cleaning

The enclosures used for the PRS 40 EZ system are water protected to IP 65. This means protection against the environment, such as rain. However, through the use of spray cleaner at short distances, it is possible to force water through the gasket or strain relieves. For this reason, avoid spraying any components from short distances with spray cleaners. Convey this fact to any member of a maintenance crew.

2) Missing / Loose Screws

All screws have to be present and to be equally tight to ensure water protection of the enclosure. If there are screws missing, replace them. If no screw is missing, check the tightness. If any were loose, then open all screws and then re-tighten them equally.

3) Broken Lid

An enclosure will only seal correctly if the lid is not bent. To check this, loosen all screws of the lid, take the lid off the box and visually inspect it for deflection. If the lid is bent or damaged, it needs to be replaced. Try to determine what has caused the lid to be bent and eliminate the reason for that. Order a new lid through your Hirschmann representative.

4) Defective Gasket

The gasket underneath the lid seals the unit. The gasket needs to be in good condition in order to seal correctly. If the gasket is torn, brittle or severely bent, it needs to be replaced. Order a new gasket through your Hirschmann representative.

Operator’s / Service Manual, PRS 40 EZ

13 MAINTENANCE

The only maintenance required is to change the batteries when required. Also, check the mounting hardware daily to ensure that there is no damage. Replace any damaged parts before operating the crane.

13.1 BATTERY REPLACEMENT

To replace the batteries, remove the 4 screws from the transmitter housing. During battery replacement, use caution when opening the battery cover and transmitter to avoid damage to the gasket causing moisture ingress which could corrode the batteries and terminals. Inspect the gasket surface on the transmitter for nicks or other damages that may prevent the gasket from sealing. If it appears to be damaged, a replacement gasket should be installed.

Install 4 fresh batteries into the proper location and direction as indicated on the battery holder.

Make sure that the cardboard tube is installed as shown.
