4.5. Programming and control
Besides the basic operations, the salt electrolysis system has an input for an external control by
means of an ORP controller, residual chlorine, etc.; as well as one for the automatic reduction
of chlorination when the pool automatic cover is closed (if equipped). Moreover, it permits the
configuration of three electrode SELF-CLEANING modes: TEST, 2/2, 3/3 hours.
ELECTRODE SELF-CLEANING System: The reversal frequency can be selected by
l
means of jumper "JP1" on the system control panel (Fig. 11). This configuration will
become effective by disconnecting and connecting again the equipment.
AUTOMATIC COVER control: the system has an input for a potential-free contact. When
l
the contact connected to this input is closed (automatic cover closed), the electrolysis
system reduces its production to 10% of its rated value (the "50%" led of the production
scale will blink).
EXTERNAL Control: the system has an additional auxiliary input for a potential-free contact.
l
This input can be used to make the electrolysis system interact with an external controller
(ORP, RESIDUAL CHLORINE, PHOTOMETER, etc.). When the contact connected to
this input is OPEN, the electrolysis system is stopped. To activate this input, place jumper
"JP2" located on the unit's control panel. This configuration will become effective by
disconnecting and connecting again the equipment.
