OVERFLOW LEVEL ALARM
If you use an APC box with analogue level sensor, and also shows the sump level in real time via the
display in both graphical and numerical mode, PC 242 allows you to generate alarms activating level
and potential free contact failure usually when they occur. Reached or exceeded for at least 5s alarm
level set to overflow level, the controller will alarm with the text "overflow". By default we deliver
pictures with a value for this alarm is adjusted according to the size of the pumping equipment which
are manufactured, if you need to adjust to an optimum value for pumping well follow the user manual
PC 242 and / or implementation guide APC 2B frame ".
PUMPPIT IN AND OUT FLOW AND PUMP CAPACITY CALCULATONS
PC 242 is constantly calculating the flows into and out the well and pump capacities. Thanks to which
we can tell the controller to a minimum value of each pump capacity, so that if the calculated value is
greater than or equal to that value, to let us know and past 10s PC 242 will create an alarm using the
alarm text "Capac. low pumping Bn "and activate the floating contact general fault. This alarm not only
the pump is indicated to help save energy and optimize pumping it with a review of the pump could
save energy and / or avoid major faults. Similarly, we can specify a maximum flow rate into the well, so
to overcome, PC 242 10s directed past the alarm text "Inflow high" and activate the floating contact
general fault. This alarm also for pumps and also signalled only helps the user.
PUMP NOT IN AUTO (NOT AVAILABLE)
Each pump has a switch "MAN-AUT-0" in front of the box to set the operating mode in which we work.
If after handling is left in position "0", the pump is out of service. To avoid this, if after 60s the selector
is not passed to "AUTO", PC 242 advised of this fact by an alarm text "not in Bn Pump Auto" and
activate the floating contact general fault. This alarm is not for the pump, only signals to help prevent
flooding in case of neglect, failure selector or otherwise.
ALTERNATION IN CASE OF PUMP BLOCKAGES
In either blocked pump alarm for not being serious or selector "MAN-AUT-0" in the "AUT", PC 242
activated with their journeys to the next by alternation. Serious alarm can be confirmed not running,
tripping of the circuit breaker or thermal probe.
LEAKAGE ELECTRODE IN PUMP FOR MONITORING
Some pumps have electrodes to detect the presence of water in areas of the pump where there should
be none. Many pumps ABS feature a moisture called DI electrode to detect the presence of moisture in
the oil chamber (or security camera pre-cooling chamber), other electrodes also feature DI in the motor
or the connection compartment. APC Table is ready to receive the signal directly electrode pumps ABS
/ Flygt without requiring buffer amplifier (known as DI module). For adequate protection and monitoring
connect these sensors to the frame correctly. In case of alarm PC 242 will not stop the bomb, but
indicate the alarm status by the text "Bn pump oil leaks" also marked by floating contact general fault.
IF THE PUMP IS NOT PROBE HUMIDITY, LEAVE WITHOUT CONNECTING TERMINALS FOR
SUCH ITEM PICTURE.
