BL530 PH/RX DOSAGE SYSTEM |
9
UV-C and Pool equipment
Flow protection:
The system is supplied already configured for disabling the dosage in case of lack of water flow.
The control is made through a contact to be connected to pins 3 and
of the FLOW connector
(see Figure). A specific flow switch is also available (optional, see “Accessories and spare parts”).
INTERNAL CONNECTIONS
(for installers only)
The unit is provided pre-wired internally, and all connections of normal use
(power supply, measurement sensors and level sensors) are available externally via
cable or connector. However, if you need to operate on the electronic boards or
replace blown fuses, refer to the diagram below.
Notes:
•
The possible reversal of the connections phase / zero of the
power supply does not affect the normal operation.
•
If the level and flow inputs are not used, leave them open (not connected).
