4. Power up the system Before power up the system be sure that all wiring is correct. Please check the power supply (230 VAC or optional 110 VAC or 24 VDC) is only on the PIN called "L1" & "N" on the terminal block. Important note: If you find no sticker on the transmitter enclosure with the optional power supply of 110 VAC or 24 VDC than the standard power supply of 230 VAC is necessary.
Page 19: Check Preset Value
MENU Menu key starts the program level Maximum key for maximum flow values Note: After pressing a key the system went into the standard readout (flow rate) after 30 seconds without pressing any further key (except in the program - MENU). With the [EXIT] key you will go into the standard readout (flow rate) at any time.

Page 30: Totalizer
5. Totalizer VARIOMASS has two independent totalizer (Z1 and Z2). Each totalizer is reset able and has to setup in the program (MENU) with start and stop time. During this time period the flow will be summed in the totalizer in cubic meter (m3) for the flow units Nm³/h or m³/min and in Liter (L) for the unit L/min..
Page 31: Reading Totalizer
Press [ENTER] to setup totalizer number 2 as totalizer number 1 Press [EXIT] after setting totalizer #2 for leaving the program and go to the standard readout. All parameters are saved in EPROM also by disconnecting the power supply after 5 minutes after the last input.
Page 32: Data Logger
6.0 Data Logger 6.1. Introduction In case that your VARIOMASS system is equipped with the Data Logger option, you will find a mark inside of electronic enclosure („with data logger“). This data logger has an internal memory of 4 Mbytes. The electronic saves the actual flow of the pressured air in a programmable time period from one day up to a few years.
Page 33: Programming Data Logger
Note: Do note use in the time period of saving 1 second for more than 4 hours per day. For longer period (> 1 day) we recommend to use a time period of 60 seconds. 6.3. Programming Data Logger The Data logger needs for activating the following pre-set values: Time period of saving interval Time and date for start the measuring Time and date for stop the measuring...
Page 34: Check Preset Value Of Data Logger
Please put in the time period for saving interval with value between 1 second up to 999 seconds. Confirm your input value with key [ENTER] and go to the next step Note : We recommend to set the time frequency of 60 seconds for records time period of more than one day.
