DPSA -2 DIFFERENTIAL PRESSURE CONTROLLER WITH DISPLAY FOR DAMPER ACTUATORS For the complete Modbus register data, refer to the product Modbus Register NO T E Map, which is a separate document attached to the article code on the website and contains the registers list. Products with earlier firmware versions may not be compatible with this list. - Page 10 DPSA -2 DIFFERENTIAL PRESSURE CONTROLLER WITH DISPLAY FOR DAMPER ACTUATORS Fig. 9 Modbus holding register reset jumper Modbus communication holding registers from 1 to 3 will be reset to the default values. Remove the jumper. Correct reading of air velocity is possible only if it is enabled by holding register ATTENTION 64 (Pitot air velocity) and a transmitter is connected to the appropriate Pitot tube connection set (PSET-PTX-200).
