    E-Compact MP-BB3 Series in a way that the electric field energy is drained away without affecting the equipment. In order to define a system, the characteristics of the soil resistivity must be taken into consideration. To determine the behavior of the soil capacity to drain the currents, its resistivity has to be measured. For an adequate protection this value should not exceed 5, with zero being the ideal value Generally, the grounding method used for TV retransmitters is a system with a single vertical electrode made with copper measuring 2.5 meters or more.

Reflected Power If the incidence of reflected power at the transmitter due to any external or internal factor occurs, refer to the measurement screen (MEASUREMENTS) by browsing the software’s navigation Menu, according to instructions given in the Operation Section of the Digital Control System. If the value of the reflected power exceeds the value of 2% of rated power, the control immediately signals through the Current Alarm LED and this triggers the routine protection against reflected power.

    E-Compact MP-BB3 Series 5.4. Transmitter Operating Temperature Configuration The transmitter’s operating temperature is measured on the power modules’ transistors and is configurable between 50°C (122 °F) and 60°C (140 °F). Configuration is done through the front panel Menu: Setup Menu “PA Temperature Control”. This configuration varies according to room temperature and the transmitter’s efficiency and is necessary to optimize the operating temperature and equipment’s lifespan.
