Safety Instructions

Combics weighing platforms have been constructed in accordance with the EuropeanDirectives as well as international regulations and standards for electrical equipment,electromagnetic compatibility and safety.

- Do not expose the weighing platform unnecessarily to aggressive chemical vapors or toextreme temperatures, moisture, shocks, or vibration.

- Do not use a Combics weighing platform in a Zone 0, 1 or 20 hazardous area.- With Option Y2 installed, you may operate any Combics weighing platform in a Zone 2

or 22 hazardous area.- Avoid exposing the weighing platform to static electricity; be sure to connect the equipo-

tential bonding conductor to the junction box.- Observe the particular IP protection rating of your scale: IP65 protection rating for

non-stainless steel models; IP67 protection rating for stainless steel models. First digit:rating 6 indicates resistance to penetration by dust particles of a specified size. Seconddigit: rating 5 indicates resistance to splashes of water as well as washdown-resistance.Rating 7 indicates resistance to penetration by water during 30-minute immersion up toa depth of 1 meter (~ 3 ft). IP 69K: protected against penetration of water into the housing by water sprayed from any or all directions during high-pressure/steam cleaningThe particular IP protection rating for the weighing platforms is ensured only if the rubber gasket is installed on the junction box and all cable gland screw fasteners aretightened securely.Improper installation will result in forfeiture of all claims under the manufacturer’s warranty.

- The junction box may be opened only by authorized service technicians who have been trained by Sartorius and who follow Sartorius’ standard operating procedures formaintenance and repair.

- If you see any indication that the weighing platform cannot be operated safely (forexample, because of equipment damage), turn off the platform and lock it in a secureplace so that it cannot be used for the time being.

- Suspension points are provided on platforms of a size of 1000 + 1000 mm or larger. If you need to transport or lift the scale or load plate using a crane, do not step under-neath the suspended scale or load plate. Be sure to observe the corresponding safety rulesand regulations for prevention of accidents. Do not damage the junction box or the loadreceptor during transportation.

- If you use suction lifting equipment to lift the load plate, always wear gloves, hard-toedsafety boots and protective clothing. Warning! This procedure can cause personal injury!Therefore, only reliable staff who are qualified to perform such work are allowed to usesuction lifting equipment.

- Always make sure the weighing platform is disconnected from AC power before performing any installation, cleaning, maintenance or repair work.

- Check the pin assignment if you use cables purchased from a different manufacturer.Before connecting such a cable to Sartorius equipment, check the pin assignment on the corresponding wiring diagram or chart and disconnect any wires that are identifieddifferently from those specified by Sartorius. The operator shall be solely responsible for any damage or injuries that may occur when using cables not supplied by Sartorius.

Setting Up the Scale

§ Choose a suitable place to set up the weighing platform. This place should have a dry,horizontal and even surface. The operating temperature range is between –10°C and+40°C (+14°F and +104°F). The allowable structural load-carrying capacity of a floor or surface must be sufficient to support both the weight of the weighing platform and its maximum weighing capacity.If you need to use the weighing platform in areas exposed to heavy traffic (e.g., fork-lifttrucks), you should install a protective frame, consisting of angular braces, around theweighing platform.Do not expose the weighing platform unnecessarily to aggressive chemical vapors or toextreme temperatures, moisture, shocks, or vibration, which could result in damage.

Note:This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to providereasonable protection against harmful interference when the equipment is operated in acommercial environment. This equipment generates, uses and can radiate radio frequencyenergy and, if not installed and used in accordance with the instruction manual, maycause harmful interference to radio communications. Operation of this equipment in aresidential area is likely to cause harmful interference in which case the user will be requiredto correct the interference at his own expense. Changes or modifications not expresslyapproved by Sartorius AG could void the user’s authority to operate the equipment.

§ The air bubble must be centered within the circle on the level indicator.

§ Level the weighing platform using the leveling feet as described below:§ Check to ensure that all leveling feet rest securely on the work surface.> Each of the leveling feet must support an equal load!§ Loosen the locknuts on the leveling feet using a 19-mm open-end wrench (spanner).> Adjusting the leveling feet:

To raise the weighing platform, extend the leveling feet (turn clockwise).To lower the weighing platform, retract the leveling feet (turn counterclockwise).

§ After leveling the weighing platform, retighten the locknuts securely as described below: Low-capacity platforms (1 load cell): tighten the locknuts against the platform frame;high-capacity platforms (4 load cells): tighten the locknuts against the platform feet.

§ If the weighing platform with option Y2 is installed in a zone 2 or 22 hazardous location,it must be grounded (i.e., an equipotential bonding conductor must be connected). This should be done by a trained technician.All Combics weighing platforms are equipped with a connector for the grounding conductorlocated either below the load plate, on the junction box, or on the base frame of theweighing platform. The position is marked in each case by the symbol shown here, indicating the grounding connection. The grounding conductor is connected to a threaded bolt or terminal screw, or a borehole is provided. If a drill hole is provided, use a stainless steel screw and nut to connectthe grounding conductor. Use of a tooth lock washer is recommended, to prevent thescrew from coming loose. The wire used for the grounding conductor must have a cross-sectional diameter of at least 4 mm2, with a suitable ring lug attached. Connect all equipment, including peripheral devices, to the equipotential bondingconductor.

Installation

§ Connect the cable of the weighing platform to the indicator.Note: The cable gland along with the screw fasteners is already pre-assembled. Use extreme care when attaching or detaching a cable. Use a torque wrench and tighten the cable gland to 5 nm.

§ Strip off the insulation at the cable end and attach the cable as follows:– Route the cable through the cable gland.– Properly tighten the screw fasteners of the cable gland– Remove the casing from a section of the cable end (see illustration).

The shield (1) must have contact with the clamps (2).– Expose approximately 15 cm (6 inches) of the wires (3) for installation.– Route the cable through the cable gland.– Make sure the shield is in contact with the clamps because the cable is grounded

by the shield.

§ Attach the cable to the weighing platform as follows:– Expose approximately 5 cm (2 inches) of the wires for installation.– Expose approximately 1 cm (1/2 inch) of the wires and attach ferrules to the wires.– Securely attach the wires to the screw terminals

* The weighing ranges allowed in legal metrology are listed in the Declaration of Conformity. On scales with two weighing ranges (2 + 3,000 e), the scale does not automatically switch back to the higher resolution of the fine range once you use the second, higher-capacity range. In other words, the lower resolution of the higher range will be retained after taring.

!Please follow the safety instructions!

CleaningSartorius platforms of the CAPFS.. Series are designed in compliance with directives of the EHEDG (European HygienicEquipment Design Group), in accordance with HACCP (HazardAnalysis and Critical Control Points) standards for prevention ofcontamination, which means they are particularly easy to cleanand disinfect.

$ Unplug the scale from the AC power before cleaning.

$ To clean the weighing platform in a dry area: use a piece of clothwet with a commercially available cleaning agent to wipe it down.Follow the manufacturer’s instructions for the cleaning agent.

!Never use concentrated acids, bases, solvents or pure alcoholto clean the weighing platform.

$ To clean the weighing platform in a wet area, wash it downusing a gentle stream of water (60°C max.) sprayed over the topof the load plate.

!Do not use high-pressure cleaning equipment to clean theweighing platform.

> If the water that you use to clean the weighing platform is toohot or too cold, the difference in temperature between the waterand the weighing platform can cause condensation within theweighing platform. This condensation may cause the weighingplatform to malfunction.

$ If the scale is installed in a pit, make sure that no debris buildsup between the pit and the platform to prevent weighing errors.

$ Regularly remove debris from the bottom of the pit.

Cleaning the Interior of the Platform$ To clean the inside of the weighing platform, remove the load

plate.Be especially careful when removing the load plate from scalesof 1000 + 1000 mm or larger.

!Please follow the safety instructions.

$ Use compressed air to blow debris out of the interior of the scale or flush out using a gentle stream of water (60°C max.). Be sure that no debris builds up in the gap between the loadreceptor and the fastening plate in order to prevent compromising the overload protection.

Cleaning Stainless Steel Surfaces Clean all stainless steel parts regularly. Use a damp cloth orsponge to clean stainless steel parts on the weighing instrument.You can use any household cleaning agent that is suitable foruse on stainless steel. Clean stainless steel surfaces by wipingthem down. Then rinse the equipment thoroughly, making sureto remove all residues. Afterwards, allow the equipment to dry. If desired, you can apply oil to the cleaned surfaces as additionalprotection.

!Do not use stainless steel cleaning agents that contain soda lye(caustic), acetic acid, hydrochloric acid, sulfuric acid or citricacid.

Corrosive Environment$ Remove all traces of corrosive substances from the weighing

platform on a regular basis.
