- Page 2 1. Out Line The KS2900 is a very small sized digital difference pressure indicator which incorporates a mono- lithic silicon semiconductor pressure sensor. It is the best solution to very low pressure measurement. KS2900 is designed for the application of the semiconductor device equipment such as Coetar Developer, Cleaning and Furnace etc and has two transistor output(NPN or PNP(option)) and analog output 4-20mA or 1-5V (Optional). Connector type ( XH connector (JST) ) 2. Handling Note Recheck the following items before turning on the power. Input and output wires, If the output terminal is connected to the power the interior circuit will be damaged. Power voltage : Pressure range : Begin actual operation after the heat line is activated for over five minutes after the power is turned on. Excessive pressure. Please do not apply pressure exceeding the maximum pressure as shown in the specification on catalogues. The excessive pressure may affect the sensor characteristics and may make accurate measurement impossible. Insert and contact of foreign matter. A pressure sensor chip is placed inside the pressure port. If foreign matter such as wire inserts through the pressure port, damage could be occur. This must be absolutely avoided. • On this manual This Manual serves to illustrate the capabilities and appropriate use of the Pressure Controller KS2900. Inappropriate use or improper handling can lead to potential hazards for persons and intrinsic values. Therefore, any person entrusted with working with the device must be instructed and aware of the potential risks. This manual and its safety notices in particular must be addressed to with care. If any doubts occur concerning the proper understanding of any paragraph of this manual, please consult the manufacturing company. Handle this manual with care: • It has to be kept within reach as long as the device is on service. • It has to be handed over to successive personnel. • Any supplements edited by the manufacturer must be inserted in this manual. • If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. • Do not close the pressure input ports when shipping, as changes in barometric pressure could damage instruments with low measuring ranges. • Only technical personnel who are appropriately trained and authorized by the operator of the facility may assemble the instrument and set up its electrical connections. • The instrument may only be operated by appropriately trained individuals who have been authorized by the operator of the facility. • Pressurized air or breath is not to be used for performance tests, as this could damage instruments with low measurement ranges.
