CEM7 controller

Automatic control panel WITHOUT ATS (Automatic Transfer Switch) and WITHOUT mains control with thermal magnetic protection (according to voltage and number of phases) and Earth leakage protection, composed by:

 

 

· Control and power electric panel, with measurements devices and controller (according to necessity and configuration), both fitted on the Genset.

· 4 poles circuit breaker with opening coil MX 230Vac

· Earth leakage adjustable protection (time [inst 0,2 0,5 3 5 sec] & sensibility [30 300mA 3A]).

– Battery charger 3A 230Vac

– Engine water preheating

 

 

The CEM7 controller unit is a device able to control de operation, monitoring and protection of a generating set. The controller unit consists of 2 different modules:

1. The VISUALIZATION module

2. The MEASUREMENTS module

 

VISUALIZATION MODULE

Provides information about the status of the device and, at the same time, allows the user to

interact with it. It consists on a backlit display and various LEDs for monitoring the status of the

controller and buttons that allowthe user to control, program andconfigure the functions of the unit.

 

MEASUREMENTS MODULE

Controls and monitors the control board. It is located in the rear part of the panel, in order to reduce the wiring and to avoid electromagnetic disturbances. Every signal, sensor and actuator is connected to this module. The connexion between the visualization module and the measurements module is made with a CAN communication bus. This feature allows the intercommunion of other modules to the main controller with a scalability warranty.

 

Control & Power Panel

1. CM Control Panel.

2. CP Power Panel.

3. On/Off Switch..

4. Emergency Stop.

5. Main Line Circuit Breaker for differential protection.

6. Main bus /hardwire connection panel with safety protection.
