PUMP RUNNING CONFIRMATION
In pictures APC finish up basic confirmation of each pump is by a signal from the motor control unit
(DOL contactor, star-delta starter, soft starter or inverter) connected to a digital input of PC 242 . In
APC Fully finished paintings used as current consumption of each pump for up confirmation thereof. In
the start-up settings for each model indicate a threshold engine for lower power consumption to
reduced power alarm, in this way for over 30s if not measured a consumption equal to or greater than
said threshold value, PC 242 means that the pump is not working properly and stop. This alarm is
indicated on the operator panel with text "Alarm No conf. Bn bomb "and is marked by floating contact
general fault. When this occurs, PC 242 for the pump and keeps it locked automatically until the alarm
reset (after which re-enters service) activates further alternating from pump failure launching the next
pump cycle touched by alternation. This function protects the pump against various scenarios: empty
working power failure, failure of motor control element, a driver may drop, etc
CRITIC ALARM: ALL PUMPS BLOCKED
If a pump is blocked by PC242 (due to an alarm or switch "MAN-AUT-0" to 0) and for some reason it
blocks the other pump, pumping out of service will be completely automatic. To indicate this, after
some time of 30s PC242 generate an alarm by the alarm text "B1 and B2 blocked". We can consider
this alarm criticism for any pump not only is indicated to help prevent flooding by an oversight or
otherwise
COMMUNICATIONS, GSM-GPRS ALARM MANAGEMENT & SMS SENDS
APC provides communications equipment and accessories that can be integrated into a network of
telemetry via Modbus or Comli. If you request the table with GSM-GPRS modem, and data
communication with the telemetry system (ABS AquaVision or similar) in its centrality or telemetry
system using Web Server (AquaWeb or similar), the modem will allows sending SMS messages to
mobile phones for alarm indication.
SEMIAUTOMATIC CONTROL SYSTEM INCLUDED IN BASIC VERSIONS OF APC
With the mode selector of specific pump in position 0, the semi-automatic system will not act on the
pump.
In pictures APC basic finish, PC242 is programmed to control the pumps with the buoy signal to sensor
failure alarm, so the semiautomatic control system only works with component failure and also against
controller failure.
