Description<\/h1>

The mixing process station mimics the industrial chemical mixing process using programmable logic controllers (PLC). Water from the supply tank will be pumped to two overhead tanks and then filled to the process tank through solenoid valves. The quantity of fluid from each tank can be controlled by the time activation of the solenoid valves, which can be set by the user in the program. After a delay the mixer motor
will be activated for a particular preset time. The station consists of the following components and the schematic of the station is given below:
\u2212 Supply Tank
\u2212 Overhead Tank \u2013 2 Nos.
\u2212 Pump
\u2212 Mixer motor
\u2212 Solenoid Valve \u2013 4 Nos
\u2212 High & Low level switches.<\/p>

      Operation & Control outline:<\/h4>

      i. Supply Tank Level Control:
      The Supply tank is connected to continuous water supply line and controlled by solenoid valve. It is fitted with high and low level float switches which directly controls the inflow to the tank using a solenoid valve.
      ii. Overhead Tank Filling:
      This is a timer based operation. The pump on the Supply tank will be running for every 10secs in an interval of 20 secs. These timings can be user defined.
      iii. Mixer tank filling:
      Two solenoid valve controls the inflow to the mixer tank. Filling duration can be controlled by a timer. The filling can also be alternate. First solenoid can be opened for 20 seconds and the mixer motor is allowed to run for 1 minutes. Later, the second solenoid can be opened for 30 seconds and again the mixer motor will
      be on for another 1 minutes. After this operation, a delay of 2 seconds can be given and the drain solenoid will be opened for 1 minutes. This operation can be repeated until the Mains switch is ON.
      Interlocks:
      1. If level low switch (LLS) is \u2018High\u2019, SV1 is ON. Start a timer. If still low for 10secs, pump, conveyor, SV2 remains off after completing current cycle. Will get reset once LLS is low.
      2. Auto \/ Manual switch can be used to switch from Auto cycle to Manual mode. In manual mode, all the outputs can be activated manually.<\/p>
