SQ0214 SYNCHROSCOPE.

SQ0214 SYNCHROSCOPE

Synchronization Meter.

Key Technical Specifications 

• • Measurement Capabilities: It functions as five instruments in one, replacing two voltmeters, two frequency meters, and a phase difference meter.
  • Display:
    • • LED Circle: 24 LEDs display momentary phase difference (Δϕcap delta phi Δ𝜙) with 20° resolution, increasing to 5° within the synchronizing range
      • (±15°plus or minus 15 degrees±15°).
      • LCD: A backlit LCD displays generator
      • (UGEN cap U sub cap G cap E cap N end-sub 𝑈𝐺𝐸𝑁) and bus-bar
      • (UBB cap U sub cap B cap B end-sub𝑈𝐵𝐵) voltages, along with both frequencies
      • (fGENf sub cap G cap E cap N end-sub𝑓𝐺𝐸𝑁and
      • fBBf sub cap B cap B end-sub𝑓𝐵𝐵) orΔϕcap delta phiΔ𝜙.

  • Synchronizing Settings: Rear potentiometers allow for adjusting:
    • • Phase difference (Δϕcap delta phi Δ𝜙):
      • typically 2…20°el2 … 20 °el2…20°el.
      • Voltage difference (ΔUcap delta cap UΔ𝑈):
      • typically 1…10%1 … 10 %1…10%.
      • Delay time (DELAY): typically 0.1…1 s0. 1 … 1 s 0.1…1 s.

  • Operating Range: Standard frequency range is 40–70 Hz or 45–65 Hz depending on the model.
  • Safety & Compliance: Rated for Installation Category III, Pollution Degree 2, and typically carries CE and ship-specific certifications like
  • Bureau Veritas. Core Functionality 

• Synchronization Relay: Activates (pulse or continuous) when pre-set phase, voltage, and delay conditions are met.
• “Dead Bus Bar” Function: Can be configured to allow synchronization when the generator is live but the bus bar is dead (below a certain noise level, e.g., 10–40%).
• Status Output: An open-collector output monitors microprocessor health, changing from low to high impedance if a malfunction occurs.
• Housing: Standard DIN housing, either 96 x 96 mm or 144 x 144 mm.
