VELP SCIENTIFICA F201A0150 ES Overhead Stirrers

General Information

Before using the unit, please read the following instruction manual carefully. Do not dispose of this equipment as urban waste, in accordance with EEC directive 2002/96/CE

This unit must be used for laboratory applications only.
The manufacturer declines all responsibility for any use of the unit that does not comply with these instructions. This unit has been designed and manufactured in compliance with the following standards: Safety requirements for electrical equipment for measurement, control and for laboratory use Electrical equipment for laboratory use

General requirement

VELP reserves the right to modify the characteristics of its products with the aim to constantly improving their quality.

Safety Regulations

The plug disconnects the instrument. Therefore, place the instrument where it can be quickly disconnected. The values indicated on the rating plate of the instrument must correspond to those of the power supply. Position the instrument on a flat surface, with a distance from the wall of 30 cm (at least). Fasten the unit to the support rod (A00001300) using the double clamp (A00001301). Secure the receptacle using the ribbon clamp (A00001302). Safe working conditions are ensured only when the accessories described in the dedicated chapter are used. The working speed set on the instrument must be such as to avoid wobbling and/or splashes. Do not use the instrument in explosive environment or with dangerous or flammable substances. The unit must not be immersed in water. It is dangerous to run the unit with the stirring blade turning in free air. Always place the stirring shaft in the receptacle before turning the unit on.

The unit is fitted with two fuses (2xT1,6 A L 250 V – 2xT800 mA x ES), found in the socket on the back. To replace one or more disconnect the mains cable and, using a screwdriver, lift up the small cover on the fuse box. It is the responsibility of the user appropriately decontaminate the instrument in case of dangerous substances fall on or in it. It is also the responsibility of the user to use safety substances for cleaning or decontaminating, which do not react with internal parts of the instrument or with the material contained in it. In case of doubts on the compatibility of a cleaning solution, contact the manufacturer or local distributor. The solution may release toxic, dangerous or poisonous gases. Adequate safety measures must be taken, in accordance with the safety regulations in force, including the presence of hood and personal protective equipment (masks, gloves, goggles, etc.).

Introduction

Overhead stirrers are generally used for laboratory applications where the solubilization, mixing, suspension, emulsioning and homogenization of samples is required. The PW, LH, LS and ES overhead stirrers with electronic speed control and advanced safety features are able to satisfy the most diverse needs of the laboratory in terms of both viscosity and volume. The chuck is keyless and ensures a secure and easy-to-fit mount for stirring shafts of up to 10mm in diameter. The stirring speed is electronically controlled. The shaft bearings and belt drive ensure silent running. VELP-SCIENTIFICA-

Assembly and installation

Check the integrity of the unit after unpacking. The box includes:

Overhead stirrer
Instruction manual
Allen key
Allen head screw
Shaft
Power suppy cable

Electrical connection
After unpacking the instrument, place the unit on the laboratory bench. Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of the power supply. Ensure that the socket and the relative cut-off device conform to current safety norms and are easy to reach.
Start-up
Assemble the shaft using the Allen head screw. Fasten the instrument securely to the support rod (A00001300) with the double clamp (A00001301). Secure the receptacle using the ribbon clamp (A00001302) to avoid damage.

Operating controls

Turn the unit on using the mains switch. Turn the potentiometer knob to be select the stirring speed. Stirring speeds are indicated on the analogue scale around the knob.
NOTE: The speed setting is saved when the instrument is turned off or if there is a power failure. When the instrument is turned on again, stirring starts at the previously set speed.

Overload protection
The current and voltage are electronically limited in order to safeguard the motor and the electronic parts against electric surges. In the event of abnormal conditions arising the unit shuts down automatically.

Over Load Current surges
The stirrer can compensate for eventual current surges for a limited period of time. If the situation persists, the speed of the motor is gradually reduced, when a speed of 0 is reached the unit shuts down.
Over Curr Rpm error
This error occurs if the chuck is accidentally blocked or if the number of revs exceeds the max. permitted value.
Over Temp Temperature error
This error occurs if the unit is used for heavy-duty work for prolonged periods of time and at an ambient temperature that exceeds the max. permitted temperature. Before resetting the instrument allow it to cool down.
Over Volt
Voltage surge

The software limits the power supply of the motor to the nominal value of the motor itself (60V). A high speed setting or a heavy load on the chuck may prompt a higher voltage. In this case the voltage is limited to the nominal value of the motor (60 Volt) and the number of revs is reduced accordingly. If for any reason the power supply of the motor exceeds the maximum threshold value of 70V, “OVERLOAD” the unit will shut down.
NOTE: To reset the unit remove the load from the chuck and turn the unit off and on again using the mains switch.

Maintenance

No routine or extraordinary maintenance is necessary apart from periodically cleaning the unit as described in this manual. In compliance with the product guarantee law, repairs to our units must be carried out in our factory, unless previously agreed otherwise with local distributors. The instrument must be transported in its original packaging and any indications present on the original packaging must be followed (e.g. palletized). It is the responsibility of the user, to properly decontaminate the unit in case of hazardous substances remaining on the surface or interior of the device. If in doubt about the compatibility of a cleaning or decontamination product, contact the manufacturer or distributor.

Cleaning
Disconnect the unit from the power supply and use a cloth dampened with a mild, non-flammable detergent.
