SEMIAUTOMATIC CONTROL SYSTEM INCLUDED IN COMPLETE 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 Fully finished system is based on an external circuit to the controller which,
when activated alarm buoy acts on ensuring the availability pumps pumping to sensor failure and even
the driver.
For reasons electrical and / or hydraulic you may want to work on semi with only one pump. To make it
easy, the APC Fully finished box has a handle on the door frame (called "SEMI COMPLETE APC") that
allows you to indicate if you want this system to act only with the pump B1, B2 with the pump, or with
both.
Once activated the alarm float pilot box excite alarm for warning buoy 2KA0 alarm and relay, starting
the pumps enabled it, ie, those selected with the selector 2S4 (called "SEMI COMPLETE APC" ) and
the operating mode selector to AUT. Pump In Tables 23A over 2TIM1 timer is used to prevent
activation of both pumps. After the buoy off (which depends on the speed of emptying the well, one's
hysteresis action of the buoy, the free cable length, the weight placement location, or that is connected
to a buoy stop function only for semi-automatic control system) pumps stop.
For APCs with soft starters, you can also use a float stop for semi-automated system that allows you to
bring more hysteresis between starting and stopping the system.
