ACS-CONTROL-SYSTEM GmbH l Lauterbachstr. 57 l D-84307 Eggenfelden l www.acs-controlsystem.de l info@acs-controlsystem.de41. Brief description21. Brief descriptionThe panel meter instrument M3-11 is a 5-digit device for direct current / direct voltage signals and a visualthreshold value monitoring via the display. The configuration happens via 4 keys at the front or via theoptional PC software PM-TOOL. The integrated programming interlock prevents unrequested changes ofparameters and can be unlocked again with an individual code. Optional the following functions areavailable: a supply for the sensor, a digital input for triggering of Hold (Tara), two analog outputs andinterfaces for further evaluating in the unit.With help of the galvanic isolated setpoints (optional), free adjustable limit values can be controlled andreported to a superior master display.The electrical connection is done via plug-in terminals on the back side.Selectable functions like e.g. the recall of the min/max-value, an averaging of the measuring signals, anominal presetting or setpoint presetting, a direct threshold value regulation during operation mode andfurther measuring setpoints for linearisation, complete the modern device concept.The panel meter instrument DAL-311 is a 5-digit device for direct current / direct voltage signals and a visualthreshold value monitoring via the display.
