IMPORTANT
The module’s 24 V power supply (terminal 25) is providing
24 V power to the IEPE accelerometer constant current
diodes. Refer to Appendix A for power specifications.
Make certain the IEPE Power parameter is enabled for
both channel 1 and channel 2. Refer to Channel Transducer
Parameters on page 58.
