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.
- A1, A2, A3, A0, AE
- Va, Vb, Vc, Vab, Vbc, Vca, VPE, VLE
- W, Var, VA, total & individual
- Hz & phase rotation sequence
- True PF crest & K factor
- WH, VarH, VAH, AH
- Demand : A, W, Var, VA
- A keyboard and 3 illuminated VFD module each with 9 character
display are used for field programming, setup monitoring
values and status.
- Setpoints to Alarms
Any of the assignable output relays may be used to trigger
and alarm for specific Conditions.
Over current...................... Motors / transformers
Under current ....................Pumps / compressors
Neutral current ...................Leakage / unbalance
Current unbalance .............Motors
Over voltage .....................Equipment protection
Under voltage ...................Motors / load transfer
Phase sequence............... Pumps / equipment
Over frequency .................Generators
Under frequency............... Load shedding
Power factor..................... Capacitor banks
Switch input .....................Process control
- 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.
