1. INTRODUCTION

The 86517 Accelerometer Interface Module is a component in accelerometer- based
transducer systems commonly used for vibration monitoring of aeroderivative gas
generators and gas turbines. The interface module is designed for use with the
Bently Nevada 3300 series 3300/95 Filter Module/Vibration Monitor and can also be
used with specially modified 3300 monitors such as the 3300/15 and 3300/25.
Section 1 describes the transducer system and its individual components and
explains some of the features of the system.
Section 2 gives typical receiving, inspecting, and installation instructions and field
wiring and hazardous area installation instructions.
Section 3 shows how to recalibrate the charge amplifier and verify the velocity signal
output. This section also contains troubleshooting information.
Section 4 provides ordering information and Section 5 describes the ordering options
for the accelerometer interface module.
Specifications are provided in Section 6.
The appendix contains drawings of the interface module, extension cables, and a
weatherproof housing. Also included are installation drawings for Canadian
Standards Association Class 1, Division 1, and CENELEC (SIRA) Zone 1, Group IIB
hazardous environments.
