6.1.1
Instrument does not switch on.
The green led under the Plexiglas cover does not have the light on.
Check that the electrical connections are properly plugged in (the cable from the analytical
unit to the power converter and the power converter to the electrical source).
6.1.2
Pumps do not operate when the instrument is on.
CL10 plus peristaltic pumps group (Code SPP 320) is made of three black rotors on a metal
support; underneath, there is an electromagnetic field that manages the rotations.
It may happen that an electrical interference (some liquid spilled on a rotor and slipping inside
the circuit) damages the rotor- circuit communication or a whole set of pumps is not
responding. Vice versa, it may happen that one of the rotors, once activated, is never
stopping, regardless the method selected or the command given.
In order to understand if the problem is given by an electrical fault, it is recommended to use
Terminal Emulation
(see § 4.6.7) command. In case a problem is found to the group of
pumps, replacement of the part is necessary.
Replacement of peristaltic pumps group
Empty the system (§5.5).
Unscrew the set of pumps from its place on the chassis and check if the motor flat cable is
correctly connected to it (Fig. 1) (if traces of salts and dirt are found, remove using a
moistened cloth).
