VLT® AQUA Drive FC 202: The specialised system with emergency mode for versatile pump control

The VLT® AQUA Drive FC 202 is a specialised system that offers a range of features for emergency scenarios. One of its most important features is the Emergency Mode, which allows pump control to operate in open and closed loop mode with an emergency hydraulic pressure signal.

This system can store up to 32 variables tailored specifically for emergency scenarios. This can be done with eight pressure or flow setpoints and four programming setups. This extreme versatility allows an entire system to be controlled by a single pump. It can adjust the mode and intensity according to the event, whether firefighting across different zones or sectors throughout multiple floors.

The versatility of the VLT® AQUA Drive FC 202 makes it possible to comply with all standard national and international fire safety regulations. In some countries, there is a requirement for a drive to operate reliably at 70°C for one hour. Although no specific regulation mentions this, VLT® AQUA Drive also meets this extreme demand.

Visual interface and self-test The drive has been enhanced at the visual interface level with an accurate list of messages and flags. This makes it easy to understand which operating mode runs via direct display or Fieldbus. Emergency Mode functionality uses the “Run to death” feature. Once the alarm ceases and the Emergency Mode function deactivates, the AC drive performs a self-test on the first power cycle. This self-test ensures it can still handle an emergency state. The display shows a “Service required” message if the test fails.
