Operating Instructions POC-M 2.2 Safety instructions Explanations of symbols Safety instructions are highlighted with warning triangles and are depicted according to the degree of hazard as follows. Attention! General hazardous area.
Operating Instructions POC-M 2.6 Safety instructions Work on the device Information Mounting, electrical connection, and start-up operation may only be carried out by an electrical specialist in accordance with electrotechnical regulations (e.g. EN 50110 or EN 60204)! Danger due to electric current It is generally forbidden to carry out work on electrical live parts. Protection class of the device when open is IP00! It is possible to touch hazardous voltages directly.
Operating Instructions POC-M 3 3.1 Product overview Product overview Operational area Control module with integrated pressure sensor e. g. for central extraction systems. In connection with an external temperature sensor outside temperature compensation is possible. The purpose of the device is to reach and maintain the target values set. To accomplish this, the measured actual value (sensor value) is compared with the adjusted target value, and the controlled value (modulation) is deduced from this.
