Timing after energization
Capability of choosing the time from 15 to 300 seconds ® Having power button
Melody running while timing
Signals:
- PWR: Input power supply
- START: Start status
Principles of Operation:
This device is designed for consumer restart in the case of re-energization. After apply- ing voltage to terminals Al and A2. PWR signal gets ON. delay time starts and melody runs. At the end of delay time. relay acts for a second and START signal gets ON. At this time. restart happens (intemal contact of terminal 15 to 18 is made) and melody stops after timing ends.
In the case of de-energization. the device gets ready to work again. Position the de- vice key in ON status for restart relay operation and in OFF status to get it out of circuit. Installation and Start-Up:
Terminas Al and A? have to be connected to phase and null It is clear that Al and A? should be connected to the main power of electrical panel and in the case of specific circuits: they should be placed after the main switch if we néed restart action ofter every network energization and de-energization.
Contacts 15 and 18 have to be connected in parallel to the two sides of start bution. This system could be used for restart of all the systems that their powers are connected and disconnected by a contractor.
