Mode 1 - Emptying And Pressurising (Default Mode) - PEDROLLO E1 MONO Original Instructions For Use

MODE 1 – EMPTYING AND PRESSURISING (default mode)
G1/P1
Water detection via cosφ (dry running)
If IN1 is closed with a NO voltage-free contact, either one pump or the other (if there are two) starts running according to
the alternating logic. The control panel then checks the cosφ.
If the following control logic has been selected:
– DRY LOGIC=COS (default) and cosφ (read)>cosφ (set min)
or
– DRY LOGIC=CURR and CURR (read current)>CURR MIN (set minimum current)
it means that the pump is operating with water in the system, so the control panel lets it run, otherwise it is stopped due
to dry running.
If IN2 is also closed with a NO voltage-free contact, the other pump starts running (if there are two). The control panel then
checks the cosφ for the second pump, using the same logic as for the first one.
If, instead, IN1 is not used, when IN2 is closed with a NO voltage-free contact, either one pump or the other (if there are two)
starts running according to the alternating logic, and the pump that was off starts running few seconds later. When both
pumps are on, the control panel checks the cosφ using the same logic as explained above.
If inputs IN1 and IN2 are enabled at any time by opening a NO voltage-free contact, one or both pumps (if there are two)
are switched off.
Pressing the ESC button shows the input states (IN1 - IN2) on the alphanumeric part of the display.
