During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGAMET 342 is a universal controller for connection of two 4 … 20 mA sensors. You can find detailed information about the area of application in chapter " Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions. -

Information: When using PACTware and the respective DTM or the VEGA Tools app, additional settings can be carried out which are not possible or only partly possible with the integrated display and adjustment unit. - Page 21 Diagnosis Includes information on device type/status, … 7.4.1 Measurement loop The VEGAMET 342 is designed for the connection of two independ- ent sensors. Thus two independent measurements can be carried out. Furthermore, a third measuring point can be used to calculate a new value between the two input values.

Page 30: Applications And Functions
10 Applications and functions The controller contains already preset applications and functions, which can be easily adjusted by means of an application assistant via PACTware/DTM or the VEGA Tools app. The following applications/ functions are described here as examples. •... - Page 31 Enter the measured value and unit (e.g. volume and m³) and the cor- responding scaling values for 100 % and 0 % (e.g. 100 m³, 0 m³). Configure relay First select the requested mode for the relay (" Overfill protection, dry run protection, switching window ON/OFF"). Also define the appro- VEGAMET 342 • 4 … 20 mA...
- Page 32 OFF. The switching points are set as follows: • Relay 1: Switch-off point 90 %, switch-on point 85 % • Relay 2: Switch-off point 5 %, switch-on point 10 % Information: The switch-on and switch-off point of the relays must not be set to the same switching point because this would cause a continuous switch- ing on and off when this threshold is reached. To avoid this effect also with fluctuating medium surfaces, it is a good idea to set a difference (hysteresis) of 5 % between the switching points. VEGAMET 342 • 4 … 20 mA...

VEGAMET 342 • 4 … 20 mA...
- Page 35 Pump control 2/4 with dry weather pump is used to protect e.g. Option Dry weather pump rain retention basins with different sized pumps against overfilling. Normally (in fair weather), a pump with low capacity (dry weather pump) is sufficient to maintain the level in the retention basin at a safe level (Hi-Level). If heavy rainfall causes an increased inflow, the fair weather pump can no longer maintain the level. In such cases, a VEGAMET 342 • 4 … 20 mA...
- Page 36 Which pump is switched on depends on the selected pump mode. If all pumps are already switched on, the pump remains switched on. Note: If the pump is already switched on when the forced switchover is activated, the timer is not started. Only after the pump is switched off VEGAMET 342 • 4 … 20 mA...
- Page 37 Select in the DTM navigation section the menu items " Meas. loop - Outputs - Relay". • Relay 1 upper switching point = 60.0 % • Relay 1 lower switching point = 10.0 % VEGAMET 342 • 4 … 20 mA...
- Page 38 HiHi level is exceeded and the dry weather pump is switched off. The large pump then remains in operation until the switch-off point is reached. If the level rises again, the dry weather pump switches back on first. There is also the possibility of using multiple large pumps in alternat- ing mode. The algorithm for the switching function is then determined by the pump control mode. VEGAMET 342 • 4 … 20 mA...
- Page 39 Since in this case all pumps operate alternately in the same area, their switch-on and switch-off points must be the same. In addition, the mode " Alternating pump operation" must be active. VEGAMET 342 • 4 … 20 mA...

Page 41: Flow Measurement Flume/Weir
This constriction creates a certain backwater depending on the flow rate. The flow rate can now be derived from the level of this backwater. The current flow rate is shown on the display in the selected unit of measurement (e.g. m /h). In addition, the flow rate is made available via the current output and can thus be further processed by down- stream devices. VEGAMET 342 • 4 … 20 mA... - Page 42 Flow formula If the flow formula of your flume is known, you should select this op- tion, as the accuracy of the flow measurement is highest here. • Flow formula: Q = k x h Manufacturer definition If you use a Parshall flume from the manufacturer ISCO, this option must be selected. This gives you a high accuracy of flow measure- ment with easy configuration. Alternatively, you can also take over Q/h table values provided by the manufacturer here. • ISCO Parshall flume • Q/h table (assignment of height with corresponding flow in a table) VEGAMET 342 • 4 … 20 mA...
