Introduction - Caframo BDC1850 Bedienungsanleitung

Introduction

All Caframo stirrers are specifically designed for professional use in the laboratory
and for use in industry to stir numerous liquids with various properties and
applications. These stirrers are available in 120 and 220-240 volt.
BDC1850 - Rotates at 12-1800 rpm with a maximum torque of 568 Ncm
BDC3030 - Rotates at 20-3000 rpm with a maximum torque of 341 Ncm
BDC6015 - Rotates at 40-6000 rpm with a maximum torque of 170 Ncm
Note: The 220 volt models operate on 220-240 volt mains voltage.
The stirrers use a digitally controlled high efficiency brushless DC motor which
yields high torque over a very wide speed range. The speed is kept constant with
continuous feedback to the motor. The stirrers are designed for reliability and
durability. There are no wear parts that require user service during the normal life
of the stirrer. There are no user serviceable parts.
The stirrers incorporate smart logic for automatic transmission control. This logic
determines the appropriate speed range at which the stirrer should operate.
See Torque Capabilities section. The automatic selection can be overridden by
pressing the speed button.
With higher solution viscosities, more torque is required to stir at the same speed.
When the torque demands are outside the instrument's range, the control logic
slows down the stirrer until the torque comes within the instrument's range. If the
torque demand is too great at the stirrer's lowest possible speed, the stirrer will
automatically shut down.
The stirrers are designed for safety. The stirrer comes on in "pause" mode once
power is activated. After a power interruption the stirrer remains off. The stirrer's
speed will gradually ramp up to the desired set point after the start/pause button
is pressed.
All stirrers have integrated electronic overload protection which ensures no damage
can occur to the electronics, motor or transmission when an overload situation
occurs, such as too great a torque demand or stirrer overheating.
A chuck guard is supplied to place over the chuck. It protects the user from the
spinning chuck and also helps to protect the chuck from potential splashes.
