GE IC3600VANB1 Annunciator Card

The IC3600VANB1 is a vital part of the turbine’s safety and monitoring system. It acts as a central hub for controlling the alarm outputs.

  • Signal Processing and Transmission: The card receives input signals from various sensors and other control cards that indicate an alarm or fault condition. It processes these signals and then sends corresponding output signals to other boards (specifically the VANA card) to activate indicator lights and other devices.
  • Alarm Bell Driver: This card houses the driver for a crucial relay, often designated as relay 30X, whose contacts are responsible for sounding the main alarm bell. When a fault is detected, the card triggers this relay, providing an immediate audible alert to the operator.
  • Flashing Signals: The IC3600VANB1 generates a flashing signal, typically known as FL, which is distributed to all associated annunciator cards. This flashing signal is what makes the alarm lights flash when a fault first occurs, drawing immediate attention.
  • First-Out Logic: The card is integral to the first-out alarm logic. When the first fault in a chain of events occurs, it triggers both a flashing light and an audible alarm. Subsequent faults will only appear as steady, non-flashing lights. This helps operators quickly identify the root cause of an issue.
  • Test and Reset Functions: The card works with system-level buttons like “Alarm Reset” and “Acknowledge” to manage the alarm state. For instance, pressing “Alarm Reset” causes the card to send a signal to silence the audible alarm and change the flashing light to a steady one, acknowledging that the operator is aware of the issue.

الوصف

The GE part number IC3600VANB1 is an Annunciator Control Card. This electronic circuit board is a component of GE’s legacy Speedtronic Mark I and Mark II series turbine control systems. Its primary function is to manage and transmit signals that drive the visual and audible alarm systems. It works in conjunction with other annunciator cards, like the IC3600VANA1, to provide operators with critical notifications about the turbine’s operational status.
