In order to prevent information loss in case of switching off the general power source, IC WM is supplying through the supervisor MAX 691 from accumulator of 3.6 V and 60 mA h which is only connected with WM in case of supply has stopped. In normal conditions the above accumulator is being charged from power source of -t 5 V.

Mechanically cleaned racks allow smaller clear openings because head loss does not become so high. Mechanical cleaning can be intermittent or continuous. Intermittent cleaning is cycled by float-operated switches controlled by a float in the influent channel. 

But where accurate speed control is the process requirement, static controllers, termed slip recovery systems (Section 6.16.3) are recommended, which in addition to exercising extremely accurate speed control, also conserve slip losses. Static drives are discussed in Chapter 6. Below we will describe a procedure to determine the value of resistance, its steps and switching and control schemes for these steps for a rotor resistance starter. 

Due to excessive starting and braking heat losses it is not advisable to switch an induction motor ON and OFF frequently. The number of starts and stops a motor is capable of performing will depend upon its working conditions such as type of switching, braking and load demand etc. and can be determined from... 

If a large induction motor is switched on such a system it is possible that its rotor may lock up at the sub-synchronous speed and keep running at higher slips. This situation is also undesirable, as it would cause higher slip losses in addition to higher stator current and overvoltage across the series capacitors.

If it is very high, so that its power loss Vf/Rj is low then it may be left permanently in the circuit. Otherwise it should be introduced into the circuit only during interruption through the switching device) (wired across the N(D contact of the switching contactor). This will provide the resistance across the capacitor banks when being interrupted and short-circuit it when closed. 

This is a significant loss. The resistance therefore should be connected during an interruption only, through a switch (or the no contact of the interrupting device which can easily carry this short time burden) and should not be left permanently in the capacitor circuit.
