Application C6097 with CE approval. Hand wheel with mbar scale. M16 cable gland for electrical connection. C6097 with UL listing and FM approval. Hand wheel with "WC and mbar scale. 1/2" NPT conduit for electrical connection. C6097 can be supplied with lock-off function. 1 Application The pressure switch monitors extremely low pressure differentials and triggers switch-on, switch-off or switch-over operations if a set switching point is reached. The switching point can be adjusted using a hand wheel.

Function 3 Function FM approved and UL listed pressure switches Pressure switch C6097A switches with falling pressure, C6097B switches with rising pressure. Once the set switching point is reached, a micro switch is activated in the pressure switch which is designed as a change-over contact. Hand wheel NO 1/2" NPT Conduit NC COM The switching pressure is adjusted using a hand wheel. 4 CE approved pressure switches Hand wheel M16 x 1.5 NO NC 4 2 1 C6097 · Edition 01.
Function 3.2 Positive pressure measurement 3.4 Differential pressure measurement Positive pressure measurement is designed, for example, for checking the fan function or measuring the min./max. gas pressure. Differential pressure measurement is designed for safeguarding an air flow rate or for monitoring filters and fans, for example. 4 4 2 2 3 1 1 3 Gas, air, flue gas, biogas The positive pressure is measured in the lower diaphragm chamber, port 1 (or 2).

Function 3.6 Wiring When using silicone tubes, only use silicone tubes which have been sufficiently cured. Vapours containing silicone can adversely affect the functioning of electrical contacts. In the case of low switching capacities, such as 24 V, 8 mA, for example, we recommend using an RC module (22 Ω, 1 μF) in air containing silicone or oil.
Project planning information 4 Project planning information 4.1 Installation Installation in the vertical or horizontal position, or sometimes upside down, preferably with vertical diaphragm. If installed in a vertical position, the switching point pS will correspond to the scale value SK set on the hand wheel. If installed in another position, the switching point pS will change and no longer correspond to the scale value SK set on the hand wheel. Switching point pS must be checked. ps = SK ps = SK + 0.
Project planning information 4.2 Ports Ports 3 and 4 are connected to the micro switch chamber. 4.2.1 CE certified pressure switches Pipes carrying gas must not be connected to port 3 or 4! 2 Rp ¼" The port that is best protected against soiling (dust/humidity) is to be left open for ventilation (positive pressure measurement) to the atmosphere.

Project planning information 4.3 Resetting pressure switches with manual reset For details of the pressure differential between the switching pressure and possible reset, see page 22 (Adjusting range, switching hysteresis). Manual reset C6097A3012, C6097A3038, C6097A3095, C6097A3111 lock off if the pressure drops to the set switching point. For resetting, the pressure must have risen to at least the set switching point plus the pressure differential between the switching pressure and possible reset.
