How to use a signal generator at the Bentley 3300 preamplifier to send a voltage signal to the DCS in order to test the circuit?
Connect a separate displacement probe at the front end unit; by bringing a ferromagnetic metal close to or away from the probe, a signal is generated. The same principle is applied when using TK3. If it is necessary to send a vibration signal, a vibration signal tester or a function generator must be used.
Without using a preamplifier, can a signal be generated by a signal generator by disconnecting the signal line going in the direction of the DCS at the signal line location behind the preamplifier?
No, a preamplifier needs to be connected. For specific operations, refer to Bentley’s relevant manuals.

Is there any instructions in the operation manual? I couldn’t find them. Could you explain it in detail? Thank you. How can a signal be sent?
It’s a voltage signal; how can it be a frequency signal? I don’t understand.
Is it a voltage signal? The output from the preamplifier to the secondary meter should be a frequency signal, right?
Are you referring to a phase or speed probe? You haven’t installed the unit displacement vibration probe; those who have done so know that it needs to be adjusted to -10v
