Level Control
The system is supplied already configured for disabling the dosage in case of low
level in the tank. The level control is made through a specific float sensor (optional,
see "Accessories and Spare Parts") to be connected to pins 3 and 4 of the LEV
connector (see Figure). When the product level in the tank falls below the level
sensor, the unit stops dosing, and the fault is shown on the display. The alarm
condition is generated with a delay of a few seconds compared to the detection of
low level to avoid errors due to extreme situations (such as water surface). Two
inputs for level sensor are available, one for each pump/tank.
Flow Control
The system is supplied already configured for disabling the dosage in case of lack of
water flow. The control is made through a clean contact to be connected to pins 3
and ╧ of the FLOW connector (see Figure).
Internal Connections (for technical personnel 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.
Start-up
At start-up, the microcontroller displays for a couple of seconds information about
the firmware (type/version), then shows the two measures flashing for all the
start-up delay time (if set), and then starts operating according to the configured
working mode.
