Excitation frequency (0x80n1:14), excitation voltage (0x80n1:15)

Notice

Setting and activating the excitation frequency and excitation voltage

  • Check the supply to the power contacts (see chapter EL5072 – Diagnostics).
  • Set the excitation frequency index 0x8001:14 "Excitation frequency" and excitation voltage index 0x8001:15 "Excitation voltage" centrally via the first channel. These settings are then valid for both channels.
  • Before switching, make sure that both sensors support the set range!
  • The excitation voltage is switched off in the delivery state and must be switched on by setting index 0x8000:08 "Enable excitation" to TRUE.

Excitation frequency (index 0x8001:14)

The EL5072 provides a high-frequency alternating voltage for sensor excitation. Predefined excitation or carrier frequencies are provided for this purpose. Since it is a joint excitation source for both channels, the settings must be made in channel 1.
