6 INTRODUCTION The flow alarm units FA... are used for monitoring failures of sample gas or test gas in analysing equipment or analyse systems. The patented M&C flow alarm sensor FA-1/2/3bi can only be used on flow meters with meter tubes out of transparent material. By means of the optical scanning, it is possible to register also very small flow quantities for example in case of non-metallic or small particles. We can also supply a high temperature version for temperatures of up to 180°C.

9 DESCRIPTION The M&C flow alarm sensor FA-1/2/3bi consists of a compact aluminium body with a fixed, open prism and a pressure screw. This makes the positioning of the flow alarm sensors FA-1/2/3bi onto the measuring glass of the flow meter very easy; it is not necessary to disassemble the measuring glass. Three basic versions FA-1bi, FA-2bi and FA-3bi cover a measuring glass diameter range of 5-55 mm.
10 RECEIPT OF GOODS AND STORAGE Please take the flow alarm units FA... and eventual special accessories carefully out of the packaging material immediately after arrival, and compare the goods with the items listed on the packing list. Check the goods for any damage caused during delivery and, if necessary, notify your transport insurance company without delay of any damage discovered. The flow alarm units FA... are containing 1 to 4 parts depending on the desired range of delivery: 1.
12 MOUNTING Fix the flow alarm sensor , while the connection cable points to the left side (M&C-imprinting is readable) and using the locking screw onto the flow meter’s measuring tube on the desired control point for a min.-alarm (floating particle is situated in normal operation above the flow alarm sensor) in such a way that the light beam of the flow alarm sensor will not be deflected by eventual inscriptions or coloured background of the measuring tube.
13.1 ELECTRONIC CONTROLLER FA-1.1 For the electrical connection, the following steps have to be executed (see figure 2): Loosen the 4 lid screws and remove the lid. Direct the connection cable through the respective clamping screws. The electrical connection of the sensors FA-1/2/3bi is to be made according to the colours of the terminals 5 = yellow, 6 = green, 7 = white and 8 = brown. The electrical connection of the sensor KS 2 and the pre-amplifier K-FA..
13.2 ELECTRONIC CONTROLLER FA-1.4 For the electrical connection, the following steps have to be carried out (see also figure 3): The electrical connection of the sensors FA-1/2/3bi is to be made on the terminals 5 = yellow, 6 = green, 7m = white and 8 = brown. The electrical connection of sensor KS 2 and the pre-amplifier K-FA.. is to be made on the terminals 15 = yellow, 16 = green, 17 = white and 18 = brown. The voltage supply happens on the terminals 1 = L, 2 = N and 4 = PE.

Without feeding of gas, the floating particle is placed on the float stopper on the bottom of the flow meter measuring glass. In case of mono-stable function, the sensor is fixed to the meter tube in such a way that the floating particle is placed on the lowest position (alarm point) and the light beam of the sensor is blacked out. For adjusting the alarm level, the float stopper must be regulated.
Adjust the voltage signal on the electronic board of the pre-amplifier K-FA.. for both photo transistors to a value between +0,08 (lowest sensitivity) to + 0,18 VDC (highest sensitivity). The tension is to be measured on the connection points of the sensor’s connection cables or the soldering points M1 – M3. The adjustment is to be made on the potentiometers P1 and P2.
15 CLOSING DOWN For closing down the equipment, no special measures are to be taken. 16 MAINTENANCE AND REPAIR NOTE! Before carrying out any maintenance or repair work, the specific safety procedures pertaining to the system and the operational process have to be observed! The flow control units series FA® are functioning without necessity of maintenance over a long time. It may be that the LED and the phototransistors of the flow alarm sensor FA-1/2/3bi must be cleaned due to dust deposits.
