User manual HONEYWELL SDBAM

[. . . ] inductive loads can cause contact burns or fuse the contacts. Preventative measures must be implemented by the customer, e. When using the version with ZF 1979 (oil and grease-free), take care to avoid recontamination of surfaces that are in contact with media, right through from opening the packaging to completed installation. generally , no liability will be assumed for oil and grease-free version. [. . . ] Basic equipment of the pressure monitors / pressure limiter Chapter 1 describes the basic equipment and the installation of the pressure monitors (without any additional function). Further chapters deal with versions and additional functions. 1 Technical Data (basic equipment) Pressure connection External thread G | A (pressure gauge connection) according to DIN 16 288 and internal thread G [ according to ISO 228, Part 1. Switching device Sturdy housing made of sea-water resistant aluminium die casting with plug connection (200) or terminal connection (300). Medium temperature 70 °C, higher medium temperatures are possible if the above limiting values at the switching device are not exceeded by suitable measures (e. At ambient temperatures below 0 °C, ensure that no water condensation can arise in the sensor and in the switching device. All pressure switches in the DWAM, DWAMV and SDBAM series are calibrated by the manufacturer for rising pressure. In accordance with regulations, they may only be used as maximum pressure monitors or maximum pressure limiters. For switching with rising pressure, this means: (Lower range limit) The smallest switching point that can be set is higher than the start of the scale by the value of the switching differential. The DWAM or DWAMV then switches back to the start of the scale in case of falling pressure. The SDBAM cannot be enabled until the pressure has dropped back to the start of scale value. (Upper range limit) The highest switching pressure that can be set is the end point of the scale. The DWAM and DWAMV switch back once the pressure has fallen by the switching differential value. The SDBAM cannot be enabled until the pressure has fallen by the switching differential value. The following applies for all devices: All switching and reset points must be within the limits of the specified setting range given in the technical data sheets. The cable outlet can be in any of 4 positions, which are at 90° in relation to each other. Installation: Directly on the pipeline (pressure gauge connection G|) or with 2 screws (4 mm) on a level surface. Tighten only on the hexagonal of the pressure organ, never use the housing or plug as a lever arm. On devices with terminal connection housing (300) the terminal board is available after removing the terminal box lid. External thread G | HH (Pressure gauge connection) When using flat seals, turn in the centering screw (depth A approx. The switching pressure is set using the setting spindle. Before setting loosen the setscrew located above the scale by approx. [. . . ] Setting sequence a) Upper switching point (with increasing pressure), with outer spindle, according to scale or pressure gauge b) Switching difference (with decreasing pressure), with small, internal grup screw, results in lower switching point. Maximum pressure limiters with mechanical interlock of the switching state (SDBAM. Instead of the microswitch with automatic reset, a "bistable" microswitch is installed in the limiters. When the pressure reaches the value set on the scale, the microswitch switches over and remains in this position. [. . . ]
