- Page 7 The P represents the maximum static pressure of the fan in mm c. to. The siphon must allow its cleaning for the purposes of regular maintenance. WIRING DIAGRAMS - FAN One of the vital components for the correct functioning of Casals Ventilación recovery units are the fans, so their correct connection must be guaranteed according to the following schemes.
- Page 8 The installation of a cut-off switch is of major importance in order to safeguard those performing safety / maintenance interventions in ventilation equipment, and is obligatory to comply with the Machinery Directive 2006/42 / EC. Thus Casals Ventilación recovery units can be supplied with mounted cutting switches. The diagram below shows the connection diagram of the cut switch.
- Page 9 ACCESSORIES - CONSTANT FLOW The constant flow attachment allows the flow to be maintained constant regardless of the variation of the system load loss. The flow con- trol is carried out using a relation between the occupied air flow rate and the pressure differential as indicated in the following image. A- Differential pressure sensor.
- Page 10 The constant flow regulation is made in the flow controller, establishing a percentage value of the operating range selected in the differen- tial pressure sensor. For proper regulation you must follow the following steps: · Limit the operating range of the fan (JP1, SW2, R28, R29) ·...
- Page 11 The regulation of the CO control is carried out in the CO controller, this being a percentage value of the reading range of the sensor in relation to the desired carbon dioxide concentration (ppm). For proper regulation you must follow the following steps: Limit the operating range of the fan (JP1, SW2, R28, R29) Regular SW1 (desired setpoint according to image).
