Operation
The transmitter has a non-intrusive operation interface. The front face contains a capacitive
contact that operates like normal push buttons. To operate a push button, simply place your
index finger on the glass over the desired arrow.
5.1 Operator Interface
Operator Interface, illustrated in Figure 5-1, consists of a four-button keypad, four LEDs and a
LCD. The DTM provides a non-intrusive operator interface allowing calibration and
configuration. This allows the operator to calibrate and change settings while maintaining the
explosion proof integrity of the transmitter. LED’s A1, A2 and A3 denote active alarms when
illuminated in the color red. LED F denotes unit failure when illuminated in the color amber.
