1 frequency inverter for the pumps control.
n
1 power relay to alternate the main pump.
n
Wall-mounted
n
Control and safety system against overload.
n
Control and safety system against dry run.
n
ART function (Automatic Reset Test). If the device has been stopped due to the action of the safety system
n
against over-current, the
supply could have been restored
Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC mode
n
keeping the configuration parameters (see "CONFIGURATION" chapter).
STC function (Smart Temperature Control ). Overheating protection. This device has protection to avoid
n
overheating failures that could be produced in adverse environmental conditions, operating continuously and
with current draw close to the nominal power of the device. If the electronics exceed 85ºC under these
conditions, the maximum operating frequency will automatically dicrease in order to reduce consumption. As
soon as the temperature of the electronics drops to 80ºC, normal operation will be restored.
External pressure transducer (4.20 mA) under demand.
n
External programable input with three options: Level, ON/OFF and Second pressure.
n
Control panel (Fig.1):
n
LCD screen, for alarm menu with permanent pressure indication.
n
START/STOP push-buttons to act by hand each one of the pumps
n
ENTER pushbutton to save data in memory.
