Introduction HL-G1 User's Manual The system will be ready to operate approximately 40 to 50 seconds afterthe system is turned ON, depending on the contents of settings. Note thatthe status of the outputs is undefined during startup. An analog voltage of 11V and an analog current of approximately 21.6mAwill be output until the system becomes ready to operate. Do not turn OFF the system while system settings are being saved. In theworst case, the sensor head may be damaged and fail to restart. If an instantaneous power failure occurs, the system will operate continu-ously or go to the initial power-on state, depending on the duration of thepower failure. Do not use the system in environments where instantaneouspower failures occur.1.1.4 Noise Countermeasures Install the system separated as much as possible from noise-generatingsources, such as high-tension lines, high-voltage equipment, power lines,power equipment, machines generating high-voltage ON/OFF surges, weld-ing machines, and inverter motors. Install the system separated as much as possible from radio equipment in-corporating transmission circuitry, such as amateur radio transmitters. Do not touch the connector parts when the system is energized. Keep inmind that the internal circuit may be damaged if an excessive level of staticelectricity is imposed on the connector parts. Keep the sensor cable at least 100mm away from other wires and make surethat the sensor cable is not in parallel with them. Separate the sensor cablefrom high-voltage and power circuit lines. Shield the sensor cable withgrounded conduits if it is unavoidable to lay the sensor cable together withhigh-voltage or power circuit lines. Keep the I/O signal lines at least 100mm away from power lines and powersupply lines. All signal lines should be connected as short as possible. The analog output of the system is adversely influenced by heavy noise inthe power supply. In that case, use a noise filter or noise-cut transformer. It is recommended to use shield cables for I/O signal wires and connect theshields to the FG. The analog output is easily affected by external noise. Use the shield cableand lay it as short as possible. Ground the FG independently at a resistance not exceeding 100. The FGmay be adversely affected if the ground is shared with other equipment.Rugghölzli 2CH - 5453 BusslingenTel. +41 (0)56 222 38 18Fax +41 (0)56 222 10 12mailbox@sentronic.comwww.sentronic.comProdukte, Support und ServiceSENTRONIC AG
