EM-V

Extension module for parallel actual value recording of the volume flow rate with duct pressure or room pressure control function with TROX UNIVERSAL controller. The extension module contains a differential pressure transducer with connection and support by the TCU3 controller board, thus enabling the provision of an analogue signal for the actual volume flow currently recorded in the pressure controller at the differential pressure sensor.

Special features

• Pressure control and volume flow measurement in one electronic unit
• No additional electronic component required for volume flow detection

Technical data

• Effective pressure transducer with static pressure measurements
• Supply and signal voltage suitable for the TCU3 controller board of the TROX UNIVERSAL controller
• Actual flow rate value available on TROX UNIVERSAL controller as analogue signal
• Actual volume flow value also available as a network data point via additional expansion module

Commissioning with factory preparation

• When ordering the TROX UNIVERAL pressure controller with EM-V expansion module, the module is factory-installed, hosed, electrically connected and ready for operation.
• Manual zero point adjustment must be scheduled as part of commissioning on site

Installation and commissioning for retrofitting

• Disconnect the TROX UNIVERSAL controller from power supply
• Install the EM-V expansion module and plug the connection cable into the TCU3 controller board. Observe the required installation position of the expansion module (pressure transducer)
• Connect the expansion module to the differential pressure sensor of the control unit using the hoses supplied
• Activate volume flow measurement function with EasyConnect configuration software
• Zero point correction of the differential pressure transducer with EasyConnect configuration software is required (only if no EM-AUTOZERO is used)
• Annual zero point correction is required, or use the EM-AUTOZERO extension module to reduce the maintenance effort
