Pi SERIES SYSTEM: CONTROL UNIT
Series Pi Each system consists of at least a controller and a digital panel. multiple panels and control units can be Added the system as needed.
The control
The controller is the brain of the system and receives requests from the switch panel or panels, and then processes these commands based on the actual state of the system. The response to a request for switching on or off nell''attivazione may consist of a circuit, in the initiation of a timer function, or in the case of systems equipped with starting, locking or unlocking the system without keys. The controller then sends the information on the state of the panels to turn on or off the LED indicators and backlit buttons.
electro-mechanical unit control
Pi Series provides two types of units
The controller uses electromechanical relays for switching loads and overload protection with circuit breakers. Each electromechanical unit is able to control 20 outputs a constant output switchable and protected by circuit breakers 16. All switchable outputs can also be used as inputs for detection of 12V. For more information, refer to the worksheet of the standard ECU. All electromechanical units are factory according to your specifications.
The controller uses solid-state intelligent solid-state relay for switching loads and overload protection. Delete all the mechanical components. Each unit is solid state switch output can control 16-21 / constants. The use of solid state switches allows you to reset the faults of the circuit by acting on the control panel. A flashing light on the panel reports any faults to the circuit. To reset the circuit, simply press and hold the respective indicator. The solid-state unit can be programmed in the field or pre-programmed at the factory. The controller is a solid-state drop-in replacement for the electromechanical controller.
INTERFACE ELECTRONIC
The electronic interface allows you to connect the traditional analog switches and other components of the PI series. It 'a way economic to duplicate some functions from a remote location. Each electronic interface accepts up to four analog inputs can operate in each indicator on a switch and also supports the circuit breakers with back-lighting. On each connector is placed an indicator that glows when its function is ON. The fifth indicator lights up when the backlight circuit is ON.
Advantage Series Pi
Increased functionality
Increased reliability
Reduced warranty costs
Easy wiring harness
The lower weight means greater energy savings and improved performance
Shorter installation
leaves more space for other accessories above and behind the bridge
