    INTRODUCTION

    The Red Rooster ATEX / IECEx wireless load cell is approved for use in Zones 1 & 2 for Gas and also Zones 21 & 22 for dust.

    ATEX coding - Ex II2 GD IECEx coding - Ex ib IIC T4 Gb Ex ib IIIC T135°C Db

    This intrinsically safe wireless load cell is part of the RRI-T range of wireless load cells developed over many years by Red Rooster to meet the increasing requirements of our customers. Ideal for use in the offshore industry, engineering and chemical industries and wherever accurate measurements are required in a hazardous area. The load cells range from 5 tonne to 500 tonne and are manufactured from high strength low weight Duralloy. All load cells are proof loaded to 150% of the rated capacity with a minimum factor of safety of 5:1. The load cell and the handset has IP67 protection against water and dust. The handset has an easily accessible battery compartment and the batteries on the link are accessed by remving a panel with 4 x M6 socket head cap screws.

    Load cells come complete with a robust carry case up to 50 tonne and a case for the handset over 50 tonne.

    The handset can be changed to indicate Tonne and LBS.

    SAFETY INSTRUCTIONS

    1.0 INSTRUCTIONS FOR THE SAFE USE OF LOAD CELLS

    Instructions for the safe use of RRI-T-ATEX Load Cells and Displays

    The information in this leaflet should be passed to the user of the equipment. The contents of this section are designed for the guidance of personnel using Load Links.

    LOAD CELL CHECKS

    Ensure the serial number, capacity, calibration date and the Ex rating are easily read and match the calibration report. Ensure that the load cell / rigging gear is of an equal or greater capacity that the load being applied. Ensure that the rigging gear fits correctly into the link. Ensure that the load runs through the centre of the link. Ensure that the operator will be able to read the load on the load cell display when needed. Ensure that the load cell works correctly before lifting the load.

    WHEN IN USE

    Read the manual before use. The load must be applied in a linear manner. Do not apply a shock or twisting load to the load link. Do not leave in the sun. Cover from direct sunlight when not in use. Do not drop or apply a mechanical blow to the load link or display unit. Do not immerse either the load link or display unit in any fluids. Avoid use for 15-20 minutes after moving between areas of different temperatures. The device is sealed to IP67 standard The use of chemicals on the load cell should be avoided. Be aware of external influences on the load cell such as ambient temperature, wind, rain, chemicals and coming in contact with moving objects.

    SAFE OPERATION

    Test run the equipment prior to application of a load and ensure that the equipment, including its control and safety devices are functioning correctly. Ensure that only authorised personnel operate this equipment. Do not exceed the stated safe working load / capacity. Ensure that the load is securely supported by certified lifting gear (slings and shackles) with an equal or higher safe working load in the configuration used and that the load to be lifted cannot ‘escape”. Stand clear of the load when lifting or lowering, and ensure that the point which you are standing is safe and secure and within range of the load cell output. Ensure that other personnel cannot enter the immediate area where the lift is taking place. Never leave a suspended load unattended. If it is not possible to site yourself in a position where you can see the load at all stages, appoint a ‘banksman’ to cover the area which you cannot see and establish a reliable method of communication (verbal or hand signals) before starting the lift. If you suspect that the equipment is defective or is developing a fault, stop the lifting operation immediately. Make the area safe by returning the load to a rest position, but if this is not possible the area should be cordoned off, and the advice of you Superior or Safety Officer sought. Do not use if damaged or if you know the load cell has been overloaded. Batteries must be correctly fitted and the battery compartment cover must be securely closed.

    1. The certification marking is as follows:

    The Durablack label is manufactured from anodised aluminium with a Durablack coating. The label is self-adhesive.

    2. The equipment may be used in zones 1 & 2 with flammable gases and vapours with apparatus groups IIA, IIB & IIC and with temperature classes T1, T2, T3, andT4.

    3. The equipment may be used in zones 21 & 22 with flammable dusts, fibres and flyings in groups IIIA, IIIB and IIIC, with a layer auto-ignition temperature of not less than 75 K above the maximum surface temperature marked in the dust coding.

    4. The equipment is only certified for use in ambient temperatures in the range -20ºC to +40ºC and should not be used outside this range

    5. Installation shall be carried out in accordance with the applicable code of practice by suitably-trained personnel

    6. There are no special checking or maintenance conditions other than a periodic check.

    7. With regard to explosion safety, it is not necessary to check for correct operation.
