The devices of the double limit monitor / level generator of the series GW4 have been developed for monitoring norm signals and are able, by usage of a corresponding sensor, to record fill levels and/or to generate levels in vessels. They also can be used as a temperature limit monitor or temperature controller by using a Pt100/Pt1000 sensor and, for example, a transducer series PT3 (LEG). The user can choose between a voltage- or current input. While using the current input 4...20mA it is additional monitored for wire breakage (<3,8mA) and short circuit (>20,5mA). The range 0…20mA and 0…10V is monitored for under- or overrun of the measurement range. The accurate function is indicated by a malfunction message output (high if there is no - low if there is a malfunction). Additionally a report in the bottom line of the display appears. The switch conditions of the relays are signaled by each one LED in the front panel. The switch performance can be configured via 3 tactile switches and a LC-display. Switch delay, hysteresis and inverted switching are freely adjustable, separated for each channel. The chosen operating modus direct = double limit monitor or level max / level min = level generator is shown in the bottom line of the display. For the supply of the required sensor there is an auxiliary power of 24V / 20mA at disposal. The modules are mountable on cap rail TS35, they have a wide range power supply so that a supply in the range of 20…253Vuc is possible.
