TROX LABCONTROL – TFM

Areas of application:
Proper aerodynamic functioning of a fume cupboard must be monitored in accordance with EN 14175-2 by a fume cupboard function indicator. Visual and acoustic alarms must be issued if a malfunction occurs. The Labcontrol TFM monitoring equipment is designed for such applications.

Unit variants:
TFM-1 with integrated measurement of the actual volume flow rate that have to be monitored. The measurement is done by an integral differential pressure measuring device using a differential pressure measuring probe.

TFM-2 with an analogue 0-10V input for the actual volume flow value to be monitored. (Specification of the actual value for the volume flow by the output from a VAV controller, for instance)

The monitoring devices are supplied with a standard operator’s terminal to signal alarms and to activate special operating modes. An AF-1 extended operating terminal is offered as an option for additional functional features.

Scope of functions:
  • 2 volume flow monitoring values with the following configuration options:        - Delay time until alarm is triggered following a value threshold being passed - Duration of the acoustic alarm                                                                                  - Alarm passed via the alarm relay, e.g. to the building management system (BMS)
  • Monitoring of the front sash opening (>500mm) with visual alarm and optional acoustic alarm
  • Disabling the monitoring function, e.g. for night-time operation
  • Signalling of a power failure in the monitoring system by a visual indicator in the operating terminal and/or by relay contact to the building management system
  • Control switch for switching fume cupboard lighting on or off 
  • Visual display of service interval (only with optional control panel AF-1)
  • Control elements for operating a sash window closing unit (only with optional control panel AF-1)
Configuration:
The TFM units are configured by using the TroxMConnect PC software and a serial configuration cable. All alarm settings and connection options can be easily and quickly set and the current volume flow values and reasons for an alarm can be queried.
