While programming, pressing button saves the current parameterand moves to the next programming step. For selection within a parameter or for entering data, usebuttons and .Button combinations:+ one parameter back.+ setting parameter to zero or minimum value.After powering up, the device initializes itself. The display shows the message DMS1000 and software version.After the initialization the device is located in the Working level. The set point of the alarm output can be adjustedand min- and max. values can be called.Pressing the button for more than 2 seconds, activates the Configuration level. Now all the parameterswhich defines the function of the converter can be programmed.After finishing the configuration or when no button was pushed for more than 2 minutes, the program returns tothe working level and the display shows the process value. Leaving the configuration level is possible at anytime by pushing the button for 2 seconds.Error messages:Display flashes If the input signal leaves the programmed range.P-ERRORFactory calibration is necessaryP-lock Programming lock. See configuration page 7, parameter 23Installation note!Before the device can be used, it must be configured for the intended use. ⇒ see page 5- 3 -
