- Check that all transducer inputs are correctly wired to the corresponding I/O modules before applying power.
FAQ
What does the 02 suffix represent in the model code?
The 02 suffix indicates the inclusion of specific input barrier options designed for hazardous area compliance.
Is this module compatible with standard proximity probes?
Yes, this monitor is configured to accept signals from standard proximity probes paired with Bently Nevada Proximitor sensors.
Can I replace this module while the system is running?
The 3300 series modules are designed for rack mounting, but it is standard industry practice to de-energize the specific slot or system before performing hardware installation or removal to prevent electrical faults.
