One Shot Timing Cycle

Proper wash down mixture for a food processing plant is an important factor

in maintaining the clean environment required. A disinfectant solution is added
to the mixing/holding tank used for the wash down cycle. When the holding
tank is near empty, a level transducer activates the filler pump. A C48TS is used
to turn on the disinfectant solution pump for a preprogrammed amount of time
during the filling process of the holding tank.

When the filler pump starts, a momentary contact closure activates User

Input 1, resetting the C48 Timer. The timer begins the timing cycle since the run
terminal is connected to common. The normally open relay contacts close at the
timer reset signal activating the disinfectant solution pump. When the
programmed preset is reached, timing stops and the relay deactivates, turning
off the pump controlling the disinfectant solution. The C48 Timer’s preset cycle
time may be changed according to the manufacturer’s concentration level of the
disinfectant.
