Description

Bently Nevada 3500/62 Module Operational Procedure‌

‌PN:‌ 3500/62-00-00-00
‌Firmware:‌ ≥V4.2 (Requires FrameWorks 7.0+)

‌Critical Safety Precautions‌

‌HAZARDOUS VOLTAGE ALERT‌

De-energize rack (PN: 3500/15) before module insertion/removal
Ground probe cables prior to connection (ESD rating: HBM Class 3B)
Maximum transient voltage: 250V peak (IEC 61000-4-5)

‌Hardware Configuration‌

plaintextCopy Code

[Channel Parameters]

Input Type: Eddy Current Proximitor (7mm-11mm probes)

Excitation: -24V DC ±0.1% (Stiffened)

Dynamic Range: -1V to -22V (Gap Voltage)

Bandwidth: 0.5Hz to 12kHz (±3dB)  
[Jumper Settings]

J1: Enable TMR Voting (Position A for SIL2)

J2: Probe Calibration Mode (Factory-sealed)

[LED Diagnostics] • Green (OK): Normal operation • Red (Alert): < -20V or > -1.5V gap • Amber (Fault): Loss of 24V rail

‌Wiring Requirements‌

‌Terminal‌	‌Signal‌	‌Cable Spec‌	‌Torque‌
CH1+ (TB3-1)	Probe + (Coaxial)	Belden 8761 (95% shield)	0.6 Nm
CH1- (TB3-2)	Probe –	Twisted pair 22 AWG	0.6 Nm
+OUT (TB4-1)	Buffered Gap Voltage	>16 AWG	0.8 Nm
SIG RTN (TB4-2)	Isolated Ground	Dedicated 12 AWG	0.8 Nm

‌Grounding Protocol:‌

Connect chassis to station ground (≤2mΩ resistance)

Single-point shield termination at TB5

Maintain 50mm separation from AC power lines

‌Commissioning Sequence‌

‌Step 1: Gap Voltage Verification‌

multimeterCopy Code

1. Power ON rack (Observe 3-min warmup)



2. Measure at TB4:

   • Cold Gap: -10V ±0.5V (Typical)

   • Running Gap: -12V to -16V



3. Deviation > ±5% requires probe recalibration

‌Step 2: Dynamic Calibration‌

terminalCopy Code

> cal_start 3500/62 ch1

• Apply 80µm p-p @ 1kHz via TK-3E simulator

> set_gain 4.0 mV/µm (API 670 Table 4)

> cal_verify tolerance=1.5%

‌Step 3: Alarm Thresholds‌

iniCopy Code

[Alarm_Setpoints]

Alert:  150µm p-p (Delay=2s)

Danger: 220µm p-p (Delay=1s)

Notch Filter: 1X RPM enabled

‌Diagnostic Protocols‌

‌Fault Code‌	‌Condition‌	‌Corrective Action‌
F62.01	CH1 Open Probe Circuit	Check cable Ω: ∞ >1kΩ
F62.07	Backplane Comm Loss	Reseat module (Cycle power)
F62.13	ADC Saturation	Verify gap < 2.5mm

‌Preventive Maintenance‌

plaintextCopy Code

1. Quarterly:

   - Clean backplane connector (Isopropyl alcohol)

   - Verify ventilation (ΔT ≤15°C ambient)



2. Biannual:

   - Calibration drift test (±2% FS max)

   - Tighten terminal screws (Retorque to spec)



3. Lifetime:

   - Capacitor replacement at 50,000 hrs (C101-C104)
