    3050. This DVP-120 system should be used with Macurco™ transducers and each unit will measure the level of the target gas (i.e. CO, NO2, EX, etc.) and provide this information to the DVP-120 over a 4-20mA current loop. The transducers operate on low voltage (24VDC). All power and signal connections for the transducers are provided from the DVP-120 control panel, via unshielded four conductor cable.

  • Page 17 3.5.2.5 DIP Switches and Addressing Each MRS-485 (and the partner gas detector) must be configured to a unique address. If there are 10 detectors on the serial line, then 10 unique addresses must be used, one for each detector. To set the address, use the eight DIP switch positions. For each unit choose the value from 13 to 99 (see chart) and set the eight switches to match the address.

    Macurco sensors may be tested by depressing the TEST button on the sensor printed circuit board, or (depending on the type of sensor), the button on the interior front panel of the unit. Macurco sensors will step the output current level from 4 mA to 20 mA over the course of the warm-up period, allowing the technician to determine where the trouble condition exists.

  • Page 46: Internal Controller Board Trouble

    If the sensor status display and investigative efforts reveal no problems with the input channel current loops and channel configuration, the most likely trouble condition is an internal problem detected by the DVP-120 controller. In this case, contact the Macurco Technical Support at 1-844-325-3050 for advice and help.
