During the first installation and when carrying out maintenance, make sure that
:
• there is no power on the mains supply.
• the mains supply is protected, and specifically has a high-sensitivity residual current circuit breaker (30 mA class A), suita-
ble for protecting against alternating, single-pole, continuous, high-frequency fault currents. Also check that the earthing
complies with the regulations.
• before removing the cover from the electrical control panel or starting work on it, disconnect the equipment from the
mains power and wait at least 5 minutes to allow the capacitors to discharge through the built-in discharge resistors;
• after connecting the equipment, check the electrical control panel settings as the electric pump may start automatically.
CAUTION
:
when out of service (display in the OFF state with a white background), the E electrical con-
trol panel remains live; disconnect the power from the electrical control panel before carrying out any
work.
EMERGENCY STOP
Press the I/O button while the
E
control panel is operating to perform an emergency stop
DURING THE FIRST INSTALLATION OR MAINTENANCE
Make sure that there is NO POWER on the mains supply.
Make sure that the system is NOT PRESSURISED.
PRODUCT DESCRIPTION
The
E
multifunction electric control panel is designed to protect and control 1 or 2 single-phase or three-phase electric
pumps. It allows you to select the type of operation from 6 pre-set modes to suit your system, making it easy to use.
The electrical control panel can monitor the electric pumps through pressure switches, floats, remote contacts, run/stop
floats, level sensors, 4–20 mA pressure transducers, 0–10 V pressure transducers, “cosφ” power factor and minimum current
to check for dry running (where “φ” is current/voltage phase offset) and control panel power supply voltage.
If the system has two pumps, the control panel automatically alternates between them so that they both work. This optimis-
es the operating times and wear of the electric pumps.
If one of the electric pumps malfunctions, the operating logic automatically disables that pump and uses the other working
pump in its place.
