Product Description:
space The HC 6030 Monitors current, voltage, real and reactive power, power energy, power factor, frequency ,energy demand and 8 channels for time of use to power energy .24 programmable setpoints and 3 assignable output relays allow control functions to be added for specific applications. This includes basic alarm on over / under current or voltage, unbalance, demand based load shedding, and capacitor power factor correction control. More complex control are possible using the 8 contacts uch as breaker open / closed, pulse counter to flow information or demand synchronized trigger. The HC 6030 may be used as a data glogger and accessed via RS485 and RS232 running ModBus protocol. interface to a PLC, and of the monitored values can be output to one of 4 isolated analog outputs and 2 pulse outputs. Process variables can be measured using 3 analog inputs. The power quality becomes important with the increasing use of electronic loads such as switching power or variable frequency drives. The HC 6030 displays the auxiliary input / output, any phase current / voltage c and the harmonic content calculated. By knowing the harmonic distribution, action can be taken to prevent overheated transformer, motors, capacitors, neutral wires and breaker trips.
  • Metering  Each voltage and current is sampled 64 times per cycle for 0.2% accuracy true RMS measured values.

  • Communications  Integrate process, instrumentation and electrical requirements in a plant automation system by connecting HC 6030 meters together to a DCS or SCADA system. A PC running the HC 6030 can change system setpoints, monitor values, status and alarms. Continuous monitoring minimizes process downtime by immediately identifying potential problems due to faults or changes from growth.
    • RS485 ModBus
    • 1,200 ~ 19,200 bps
    • RTU SCADA system component
    • Measure actual values
    • Read status
    • Issue control commands
    • Load all setpoints from a file
    • Change individual setpoints
  • The standard version the HC 6030 comes complete with a front RS232 port. The RS232 port can be used for data collection, printing reports or problem analysis without disturbing the main communication interface to rear RS485 port.
  • Upgrade to future expansion  Flash memory is used for firmware storage within the HC 6030. This allows future product upgrades to be loaded via the serial port. The HC 6030 meters can be used as stand-alone units however its open architecture allows connection to other ModBus compatible system for over all process monitoring and control.
  • Options  8 status input : 8 status inputs with internal DC28V powered, can be configured to 8 status inputs (break condition) or to 7 counter inputs and one demand synchronized input. 4 analog output : 4 isolated analog outputs can be used to replace 4 or more analog transducers. Output signals can be selected from any of the measured parameters.
  • 3 analog inputs : 3 analog inputs for process variables (such as temperature. Water level or flow rate etc.) Can be monitored and used for control.
  • 2 energy pulse outputs: 2 energy pulse outputs of WH and VarH can be used to energy management or used to replace energy transducer.
  • 24 setpoints with 3 relay control output
  • Control  3 output relays / 8 switch inputs / measured parameters from the standard HC 6030 can be combined with setpoints and input / outputs for control applications. With the control option, 3 output relays and 8 switch inputs are added along with programmable setpoints. Output relays can also be controlled via the communication port or assigned to different setpoints for user programming to accommodate many situations. Possibilities include:
    • Under current alarm for pumps
    • Over / under voltage for generators
    • Unbalance alarm for rotating machines
    • Dual level power factor for capacitor bank switching
    • Under frequency / demand output for load shedding resulting in power cost savings
    • KWH, KVarH and KVAH pulse output for PLC interface
    • Fault recorder for 3 voltages and 3 currents
  • Power analysis  Data logger (trending): trending is useful as a troubleshooting aid when a problem is detected. Measured values can be selected and plotted with a programmable sampling rate to suit the time interval of interest. The generated chart recorder screen can be printed or exported to other programs for report writing.Harmonic analysis: non linear loads such as variable speed drives, computers and electronic ballasts can cause harmonics which may lead to problems such as nuisance breaker tripping, telephone interference, transformer, capacitor or motor overheating. For fault diagnosis such as detecting undersized neutral wiring, need for a harmonic rated transformer, or effectiveness of harmonic filters, details of the harmonic spectrum are useful and available with the power analysis option.
  • Waveform capture : voltage and current waveforms can be captured and displayed on a PC using the HC 6030 PC program supplied with the HC 6030 or using third party software. Distorted peaks or notches from SCR switching provide clues for taking corrective action.
  • Event logger : alarms, setpoint triggers, input and output events can be stored in a 200 event record and time / date stamped by the internal clock. This is use full for diagnosing problems and system activity. Minimum and maximum values are also continuously up dated and time stamped.
  • Trace memory : the HC 6030 can be configured to record 16 to 64 cycle of data length on all voltage and current input based on setpoint activation to under voltage, over voltage, over current or switch input state change and etc.
