This system should be used with Macurco™ transducers and each unit will measure the level of the target gas (i.e. CO, NO2, EX) 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. Be sure that the 4-20mA output on each sensor is set to “On”.
2.2 General Wiring Information ! WARNING High voltage terminals (120/240 VAC) are located within the DVP-120, presenting a hazard to service technicians. Only qualified technicians should open the DVP-120 case and service the internal circuits. Ensure power is removed from the DVP-120 prior to servicing the unit. With the exception of the safety ground, all field wiring is completed via modular connectors (provided).

4 Troubleshooting The DVP-120 is tested at the factory for reliable operation. Most problems can be traced to the set-up of configurable features and modes, system wiring or trouble with the sensors. ! WARNING Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument contains no user serviceable parts, and substitution of components may adversely affect product performance and result in sickness or death. 4.
4.1.1.5 Resettable Fuse Each sensor channel is provided with a PTC-resettable fuse internal to the DVP-120 to protect against over current situations. To reset a sensor channel, power should be removed from the channel. This can be accomplished by removing power from the sensor – causing the loop current to go to zero, or by completely removing power from the DVP-120. 4.1.
Appendix A – Quick Set-up IMPORTANT: To properly and effectively program the system you must configure the Sensors, Relays, Zones and Signals. If the user has not entered any parameters, the system WILL NOT be monitoring the sensors or controlling the ventilation system.
