- Special factory‑preset configuration matches designated OEM‑project application‑scenarios, reduces on‑site commissioning‑work‑volume for target‑equipment. Application Scenarios: Condition‑monitoring and light‑duty protection for special‑specification packaged compressors, blowers, fans, process‑pumps and reciprocating‑machinery; customized OEM skid‑mount equipment matching; medium‑size unit reconstruction‑project without large‑rack TSI‑hardware; industrial‑site local‑alarm‑monitoring‑points; predictive‑maintenance data‑acquisition‑nodes requiring Ethernet‑Modbus‑communication‑access for designated‑project. Performance Parameters: Measurement accuracy ±1% full‑scale; fast alarm‑response‑speed; strong industrial‑electromagnetic‑interference‑resistance; high MTBF value for long‑term continuous‑operation. Material Composition: Reinforced metal‑alloy monitor housing; upgraded multi‑layer mixed‑signal PCB‑board; 24‑bit high‑resolution ADC chips; enhanced‑performance digital‑signal‑processing microprocessor; multi‑group electromagnetic‑isolation components; relay‑contact assemblies; screw‑type terminal‑block assemblies; LED status‑indicator components; Ethernet‑communication‑circuit components. Structural Characteristics: Rectangular metal‑enclosure for panel‑mount or 19‑inch rack‑mount installation; front‑panel LED‑status‑indicator array; rear‑side multi‑group terminal‑blocks for sensor‑input, power‑supply, relay‑output and communication‑wiring; dedicated interface‑port for remote‑display‑keypad‑module‑connection; housing surface printed with model‑number, special‑configuration‑mark, electrical‑rating and unique serial‑identifier. Working Principle: Analog‑signals from field‑installed sensors transmit into monitor‑unit via input‑terminal‑blocks. On‑board circuit performs signal‑conditioning, filtering and high‑speed 24‑bit analog‑to‑digital conversion. Internal upgraded micro‑processor executes measurement‑algorithms according to factory‑preset and user‑configured‑parameters, calculates vibration‑amplitude, shaft‑displacement, rotational‑speed and temperature‑measurement‑values. Calculated measurement‑values compare with preset Alert, Danger alarm‑threshold and combined‑voting‑logic‑conditions. When threshold‑exceeding or sensor‑loop‑fault‑event‑occurs, corresponding relay‑output takes action and event‑log records timestamped‑event‑data. Processed measurement‑data converts to 4‑20 mA analog‑output for external control‑system‑input. Measurement‑data, fault‑status and event‑information upload to upper‑host‑system through serial‑port or Modbus TCP Ethernet‑communication‑interface. Installation Requirements:
- Mount monitor‑unit on standard 19‑inch rack or cabinet front‑panel complying with dimension‑specification, fully fasten mounting‑screws.
- Strictly differentiate power‑supply terminals, sensor‑input terminals, relay‑output terminals, communication‑port and remote‑display‑interface‑terminals; perform wiring work strictly following official wiring‑diagram.
- Provide regulated 24 VDC power‑supply within allowable voltage‑range for monitor‑unit.
- If remote‑display‑keypad‑module is applied, adopt specified communication‑cable and keep installation‑distance within maximum 75‑meter limitation.
- Separate sensor‑signal‑cable routing‑path away from high‑current power‑cables to minimize electromagnetic‑interference‑coupling.
- Verify factory‑preset configuration‑parameters or complete user‑target‑parameter‑setting via 1900‑series configuration‑software, download parameters into monitor‑internal‑memory before commissioning.
- Check front‑panel LED‑indication status after power‑on‑completion, eliminate sensor‑loop Not‑OK‑fault‑status before putting monitor‑unit into formal operation. Usage Notes:
- Do not exceed maximum contact‑load rating of relay‑output‑terminals; deploy external intermediate‑relay for heavy‑load‑driving‑requirement.
- Prohibit opening monitor‑housing; internal components do not support field‑repair‑work, replace complete monitor‑unit when hardware‑fault‑occurs.
- Reserve adequate ventilation‑clearance around monitor‑housing, do not block heat‑dissipation‑area.
- Inspect terminal‑block screw‑tightness during each equipment‑overhaul‑cycle to prevent signal‑fault‑caused‑by‑loose‑contact.
- Regularly export timestamped‑event‑log‑data for equipment‑fault‑trend‑analysis‑work.
