- PC 242 enables advanced management of pumping "INPUT FLOW CALCULATION". Based on level
measurement and analogue sensor data entered into during the launch of the volume of the well, the
system accurately calculates the flow rate into the well when the pumps are stopped. It is very difficult
to implement this feature when the water inlet manifold is at levels close to the bottom of the well.
- PC 242 enables advanced management of pumping "CALCULATING THE CAPACITY OF BOMBS".
Based on the input flow and knowing that does not change abruptly whenever one starts a pump, PC
242 estimated pumping capacity running an advanced calculation algorithm based on interpolation
between input and output flows.
- PC 242 enables advanced management of pumping "OUT FLOW CALCULATION". Based on the
calculated value for the pumping capacity of each pump, PC 242 can meet the outflow both when only
one pump is running, as when several work at once (using a correction factor of pumps in parallel).
- PC 242 enables advanced management of pumping "DYNAMIC MONITORING WELL". Thanks to its
colour LCD graphic display, PC 242 displayed dynamically and numerical levels, consumption of
pumps and pumping flow rates as well as numerically the pump status, alarm signals, historical
operating and alarms, etc. Connect the signal cables box of each pump and level measuring element
to make better use and management of pump alarms and in this way work with PC 242 pump vital
signs (temperature sensors and humidity, state motor protection circuit breaker, motor consumption or
contactor activation confirmation gear pumps) and pump (level sensor and / or operating buoys and
buoy alarm). In standard execution level sensor allows monitoring APC1/2B level, flow, and
consumption in amps, to include power module option: active, reactive and apparent power, power
factor loads, mains voltage, etc.. PC 242 also allows you to trend graphs level curves, consumption
and flow pumping.
- PC 242 enables advanced management of start and stop pumping before abrupt change in level,
function known as "START EARLY IN CASE OF STORM". It is able to start the pumps in advance to
avoid overflows in the well if it detects sudden changes in level. In rainwater pumps and pumping
sewage mixed is easier than to start a storm wells filling up the dimensions will start pumping when the
bombs begin to start flooding these wells are finished without a good relationship between storage
volume and pump capacity and collector wells receiving water from other pumps. Start function level to
abrupt change allows to anticipate this situation and start the pumps prior to reaching the normal
working levels (if the level is above the elevation of unemployment), so that the water will start to
evacuate beforehand, preventing overflow and laminating the water inlet to the treatment plant.
- PC 242 enables advanced management of pumping up doing short cycles, even without water in the
well, to exercise each pump after long periods without this has worked, such a manoeuvre between 1
and 10 seconds after 2 or Stop 5 days, depending on the type of fluid in which the pump is submerged,
and the model and power of the same. It is highly recommended to use this "FEATURE PUMP
EXERCISE" also known as "DRY SEASON START" mainly in storm water pumping so as to avoid
blocking the pump shaft by oxidation.
- PC 242 Advanced manages pumping with "RANDOM STRIP DIMENSIONS REFERRED TO RUN".
From the PC 242 user interface for each pump adjust band randomly around the dimension you've set
for March, so that the pump starts randomly when the level is in the range of dimensions defined by the
height of up + / - random band said. The feature is only available to work with analogue level sensor,
not buoys, and is useful for preventing the formation of crust (and the resulting odours) regrowth on the
walls of the well at elevation where the first bomb usually tear.
