Device ПІ

Performs the following functions

• control and fixing of entrance discrete signals;
• control of the state of interconnect equipment of DD;
• acceptance and reflection of the state of interconnect equipment;
• exposures of malfunctions of work of interconnect equipment and their indication;
• connection with the top level of management, information transfer on protocol of exchange;
• testing of capacity of light-emitting diodes is from the front panel of device;
• a self-diagnose is with an action on the relay of good condition.

Adaptation for a reflection and control of interconnect equipment of DD:

• switch, bus disconnector, linear disconnector, cable earthing knife, bus earthing knife, linear earthing knife, викотний element of cell.

A schematic diagram for the reflection of the state of interconnect equipment - one of standard or for to the order of consumer in obedience to a polling sheet. The booked chart can be executed any coming from placing of light-emitting diodes.
