1 3500/70M Recip Impulse/Velocity Monitor ently Nevada sset ondition Monitoring Description The 3500/70M Recip Impulse Velocity / Monitor is a 4-channel monitor that can be used as part of the reciprocating compressor solutions package for monitoring compressor crankcase and crosshead vibration. The monitor accepts input from seismic transducers, conditions the signal to derive various vibration measurements, and compares the conditioned signals with userprogrammable alarms. Each channel of the 3500/70M can be programmed using the 3500 Rack onfiguration Software to perform one of the following functions: Impulse Recip Recip Velocity Note: The monitor channels are programmed in pairs and perform up to two of these functions at a time. hannels 1 and 2 can perform one function, while hannels 3 and 4 perform another (or the same) function. The primary purposes of the 3500/70M monitor are to provide: 1. machinery protection by continuously comparing monitored parameters against configured alarm set points to drive alarms, and 2. essential machine information for both operations and maintenance personnel. Each channel, depending on configuration, typically conditions its input signal into various parameters called static values. Users can configure lert setpoints for each active static value and Danger set points for any two of the active static values. Rev. (11/08) Page 1 of 11

The exception is when the full-scale range exceeds the range of the transducer. In this case, the software will limite the setpoint to the range of the transducer. ccuracy of alarms is within 0.13% of the desired value. larm Time Delays: larm delays can be programmed using software, and can be set as follows for all channel types: Rev.
