03 / SYSTEM DATA
3500/77M Monitoring System
The associated monitor conditions approved pressure-transducer signals and compares configured measurements with user-programmable alarm setpoints.
View monitoring functions, electrical data and environmental limits
The following values describe the 3500/77M monitoring system and its configured I/O arrangement, rather than standalone performance of the 143729-01 module.
| Pressure inputs | 1–4 channels using Bently Nevada-approved positive-voltage third-party pressure transducers, specified in psia |
| Measured variables | Discharge pressure, suction pressure, maximum pressure, minimum pressure, compression ratio, peak rod compression, peak rod tension and degree of rod reversal |
| Alarm configuration | Alert setpoints can be configured for each active measured variable; Danger setpoints can be configured for any two active measured variables |
| Frequency response | 0–5.5 kHz on configured pressure channels |
| Pressure accuracy | Within ±0.5% of transducer full range at +25°C; within ±1.0% over −30°C to +65°C |
| Input impedance | 50 kΩ |
| Transducer supply | +23.0 ±0.8 VDC, with 24.5 mA current limiting per channel |
| Power consumption | 7.8 W with transducer supplies at full load |
| Buffered outputs | One coaxial buffered transducer output per channel; short-circuit protected |
| Output signal note | For a monitor using Cylinder Pressure I/O, outputs are inverted and offset by −2.265 VDC |
| Operating temperature | −30°C to +65°C with the internal/external termination Cylinder Pressure I/O module |
| Storage temperature | −40°C to +85°C |
| Humidity | 95%, non-condensing |
| Monitor firmware | Revision L or later |
| 3500 software | 3500/01 Version 3.00 or later; 3500/02 Version 2.30 or later; 3500/03 Version 1.30 or later |
| Minimum machine speed | Standard lower limit: 60 RPM. Operation down to 30 RPM requires modification 135M8200-01 |
04 / APPLICATION
Application & Failure Scenarios
Designed for reciprocating compressor installations where cylinder pressure data supports machinery protection and operating-condition assessment.
- Pressure data unavailable: Inspect the signal path, field connections and associated I/O arrangement.
- Unstable or unexpected readings: Check the transducer, wiring and configured channel parameters before concluding that the module needs replacement.
- Maintenance troubleshooting: Loss of pressure measurements can limit condition assessment and extend fault-finding time on critical compressor equipment.
