9.2.3 Connection diagrams for unpowered hardware
9.2.3.1 Voltage-based signal
Applies to the following transducers:
• CV213 and CV214 velocity transducers.
Notes
1- Switch Sw1 is open to allow voltage-based signals to be processed.
For non-Vibro-Meter devices, the Signal Transmission Mode field has to be set to the
Voltage option.
2- Switch Sw2 can be set to position 1 or position 2 depending on the application:
• When switch Sw2 is set to position 1, the OK system check will not detect an open
circuit condition at the input to the card due to a faulty sensor or cabling (see
4.7.1 OK system checking).
• When switch Sw2 is set to position 2, the OK system check will work normally.
However, the accuracy of the measurement on the channel will be affected as the
current flowing through the resistor R2 (100 k) will introduce an error.
See 9.2.1 General considerations for information on how the set the position of Sw2.
