Time controller STP-541

Functioning
The controller works in compliance with a four-time sequence program and a preset number of cycles. A cycle is a sequence of four successive contact states. After attached power controller is automatically transferred to the program. Contact will be switched in the position 1-5 at the time t1. After time t1 pin returns to the position 1-6 for the time t2. It was not until after the time t2 the second contact will be switched in the pos. 2-7 at the time t3. After time t3, contact switched pos. 2-8 at the time t4. After time t4 the driver will start from the beginning of the cycle (from time t1). The cycle is repeated in accordance with the predefined number of iterations or infinitely at work in the "loop". Failure of supply voltage >1sec the program will stop the controller. Once again the power to the controller starts from the beginning the program including the programmed number of cycles of repetition.
