BPC instruments AMPTS III Operation And Maintenance Manual page 15

A funnel is provided with the instrument to facilitate the introduction of solid samples inside
the reactor. Once all reactors are in place, distilled/deionised water needs to be added into
the thermostatic water bath until the recommended level by using the designated hole on
the thermostatic water bath lid.
In the thermostatic water bath, the temperature is controlled by a simple and intuitive digital
interface. The instrument contains 2 LED screens: the first one displaying the current
temperature (PV) and the second one showing the desired temperature (SV). Press the button
SET to determine SV. The desired temperature can be easily selected by using the shift digit,
increase and decrease buttons. When the button SET is pressed, the last digit of the value
displayed in SV blinks, indicating that the respective digit can be changed by pressing the
buttons increase (∧) and decrease (∨). If there is a considerable difference between the
current and desired temperature in SV, the user can use the shift digit button (R/S) to select
the first digit and quickly go from 30 to 60°C, for example. Once the desired temperature is
selected, press the button SET again to save the value. Once the desired temperature is
established, the instrument will heat the water until PV and SV reach the same values. When
the light HEAT is on, it is an indication that the instrument is on heating mode. When the
temperature in PV is close to reach the SV, 2° C from SV, the light HEAT will start blinking until
the desired temperature is achieved.
NOTE: Check periodically the water level inside the thermostic water bath.
Step 5: Fixing the agitation system for AMPTS III. Connect the short motor cables (250 mm)
in series by attaching one short motor cable to each motor (excluding the last motor in the
chain), and then connecting the free end of the cable from motor 1 to the free port on motor
2 and so on until motor 9. Repeat the same operation for the remaining nine motors, creating
two groups of motors connected to each other through short cables. After that, connect the
500 mm motor cable from the last motor in the chain of each group to the motor power
splitter. Finally, use the 1500 mm motor cable to connect the power splitter to the MCU. The
last step is to connect the signal cable from the motor controller to the detection unit.
