Performance Guarantee
Select and install the appropriate HarmonicGuard® Passive Harmonic Filter in a variable torque, variable frequency AC drive application, within our published technical specifications and we guarantee that the input current distortion will be less than or equal to 5% THID for standard HGP Series filters at full load, and less than 8% at 30% load. If a properly sized and installed filter fails to meet its specified THID level, TCI will provide material for necessary modifications or replacement filter at no charge. HG filters can also provide similar performance in other drive applications such as constant torque, DC drives and other phasecontrolled rectifiers, but actual THID levels can vary by load and/or speed and therefore cannot be guaranteed. Consult factory for assistance when applying HGP filters on these types of equipment.
MINIMUM SYSTEM REQUIREMENTS: The guaranteed performance levels of this filter will be achieved when the following system conditions are met:
Frequency: 50 Hz / 60Hz ± 0.75Hz System Voltage: Nominal System Voltage (line to line) ±10% Balanced Line Voltage: Within 0.5% Background Voltage Distortion: < 0.5% THVD The input VFD current waveform shall be consistent with that of a VFD with 3% AC line reactance at full load.
NOTE: The presence of background voltage distortion will cause motors & other linear loads to draw harmonic currents. Additional harmonic currents may flow into the HGP filter if there is harmonic voltage distortion already on the system. If higher levels of harmonic voltage distortion (2%-5%) are present, please use the high background distortion version of the HGP filter.
*For PQconnect: To run PQvision software, minimum system requirements are Windows 7 and 1280x720 resolution.

Verify the Application
Make sure that the HGP filter is correct for the application. The voltage rating of the filter must match the input voltage rating of the connected drive. The horsepower and current ratings of the filter must be appropriate for the connected load.
HGP Drive-Applied Filter
The HGP is a drive-applied harmonic filter designed and developed by TCI to reduce the harmonic currents drawn from the power source by VFDs. The published HGP voltage, Power (HP or kW) and current ratings apply to matching power (Hp or kW) rated standard VFDs with six-pulse diode bridge rectifiers. The HGP may also be sized to filter other loads such as SCR six-step drives, SCR Direct Current (DC) motor drives, thyristor furnaces, battery chargers, electroplating supplies or other types of nonlinear loads. In many cases, the filter power rating (Hp or kW) will differ from load power rating (Hp or kW). Please contact TCI Technical Support for additional information and support on sizing HGP harmonic filters for your non-six-pulse diode front end VFD applications.
The HGP is a passive filter connected in series with the input terminals of a VFD or several VFDs that operate as a group. It is designed to provide a low impedance path for the major harmonic currents demanded by the drive. The filter is a stand-alone device that can be furnished in its own enclosure and mounted adjacent to the drive. It is also available on an open panel for mounting within an enclosure with the drive or other equipment.
The HGP filters consist minimally of the following features and components: · A KDR tuned series reactor to prevent system interaction and improve filter performance · An L-C-L filter circuit with: · A TCI three-phase tuning reactor specifically designed for the HGP filter · High-endurance, harmonic-rated capacitors · Larger filters may have multiple tuned circuits. Consult fuse tables to determine if the filter in question has "parallel" branches. · Bleeder resistors to ensure safe capacitor discharge upon filter shutdown · Cooling fans (on select models) to ensure adequate cooling and safe operating temperatures · Compression terminals for ease and integrity of all power and control wiring · Fuses - sized to protect the capacitor wiring

HGP Filter Overview
The HarmonicGuard® Passive (HGP) Filter provides a low impedance path for the major harmonic currents demanded by Variable Frequency Drives (VFDs). This greatly reduces the amount of harmonic currents flowing through the electrical power distribution system, bringing those harmonic currents in line with the IEEE-519 standard for harmonic distortion mandated by an increasing number of utilities.
The HGP Filter includes branch fuses on the harmonic trap circuit capacitors. These fuses are included in the design to prevent damage to the capacitors in the event of excessive harmonic trap current if the filter is misapplied.

Contactor Option (C)
This option includes a contactor, control power transformer and connection terminals in the filter circuit which allows the VFD user to control the insertion of this circuit with a relay contact in the VFD. It is recommended that the VFD contact be programmed to open the contactor below 33% motor power. For variable torque (fan) loads this will be approximately below 70% speed, so the at-speed contact may be used. This reduces the possibility of leading power factor interacting with other devices on the power system. Contactor logic should also maintain the contactor closed in cases where the VFD is bypassed and the filter is not bypassed.
No Contactor Option (S)
This option includes high quality harmonic-grade capacitors and line reactors. This filter will meet most application requirements found today. This cost-effective product is available as an open panel version, in a UL Type 1 or UL Type 12 enclosure, or in an UL Type 3R enclosure. The open panel is perfect for inclusion in an MCC section or easy installation into industry standard enclosures. The UL Type 1 enclosed units maintain the same vertical profile as the open panel design. This design is perfect for applications where floor space is at a premium. The UL Type 3R enclosure protects the filter from harsh conditions.

Over-temperature/Thermal Switch (T)
This option includes an over-temperature switch installed on both the Line Reactor and the Tuning Reactor. On each reactor, over-temperature switches are wired to a terminal block separate from the power terminals. The over-temperature switch opens if unpredicted heating occurs. An interlocking circuit should be used with the over-temperature switch to turn off the VFD to prevent filter damage in the event of filter overheating. The over-temperature switch contact is rated 6 amps at 120 VAC. The over-temperature switches are normally closed, open on temperature rise and typically have the following trip points:
· On a Class R 220°C insulation reactor, the switch opens on rise above 200°C
· On a Class H 180°C insulation reactor, the switch opens on rise above 160°C
Wire the over-temperature switches according to the reactor schematic using T1 and T2 locations on the over-temperature switch terminal block.
Figure 2: Terminal Block
If this option is ordered with the PQconnect, the Thermal switch feedback will be wired to the PQconnect board, and the PQconnect will indicate whether there is an over-temperature problem. The PQconnect fault relay (J10 header) can be used to be alerted when there is an Over-temp issue as an additional measure.

HGP Drive-Applied Filter with PQconnect
The PQconnect is an integrated controls option for TCI's industry leading passive harmonic filter used for filtering the input of variable frequency motor drives (VFDs). In the passive harmonic filter, the PQconnect provides basic tuned circuit contactor control and provides unit status detection, metering, waveforms and power quality data. The PQconnect data is made available via basic Modbus RTU over RS485 serial connection. The PQconnect is UL listed and intended for commercial and industrial applications. By default, the PQconnect is manufactured to close the contactor at 30% load.
*Please verify you have the latest manual version for your PQconnect software by visiting https://transcoil.com/products/hgp-5-passive-harmonic-filter/

Modbus RTU
The PQconnect Modbus RTU network communication interface transmits and receives command and status data from the PQconnect Modbus master over a RS-485 serial link. Modbus RTU is a simple serial communications protocol originally developed by Modicon for use with Programmable Logic Controllers (PLCs) in control of industrial devices. Modbus RTU is commonly supported by most PLCs and is an open, royalty-free communications standard.
Wiring and Configuration
The PQconnect implements a Modbus RTU Master/Slave device, which supports two-wire RS-485 signal levels. The PQconnect communication port used for the Modbus RTU interface is connected directly to the PCB. The communication port is located on the side of the PQconnect board.

The default settings can be modified via the PQconnect system menu. A Tech level access password is required to change these parameters. Ensure the board communicates to the desktop app and then First go to Menu Settings Device settings Change to desired Modbus parameters Apply Menu Save Settings. Finally, go to Menu Reset PQconnect, this will reboot the PQconnect with the desired Modbus parameters. Note: if the contactor state is closed it will open when clicking the reset command.
The network interface on the PQconnect allows the user to control the contactor and show internal status data of the HGP filter. The PQconnect PC application (PQvision) access a ModbusRTU master device for the network interface (see the PQvision application display connections).

HarmonicGuard® Passive Filter Status Warning
If the desktop interface indicates a status warning, hover over the status detection for a brief description. Depending on the condition there are multiple ways to try and clear the status warnings.
Only qualified electricians should carry out all electrical installation & maintenance work on the HGP.
Warning
Disconnect all sources of power to the HGP and connected equipment. Do not attempt any work on a powered HGP.
equipment
before
working
on
the
This HGP unit contains high voltages and capacitors. Wait at least five minutes after disconnecting
power from the filter before attempting to service the conditioner. Check for zero voltage between all
terminals on the capacitors. Also, check for zero voltage between all phases of the input and output
lines. All maintenance and troubleshooting must be done by a qualified electrician. Failure to follow
standard safety procedures may result in death or serious injury. Unless an external disconnect
means has been provided everything ahead of the filter circuit breaker, including the reactors,
will still be energized.
Receiving Inspection
The connectivity board has been thoroughly inspected and functionally tested at the factory and
carefully packaged for shipment. After receiving the unit, immediately inspect the shipping container
and report any damage to the carrier that delivered the unit. Verify that the part number of the unit
received is the same as the part number listed on the purchase order.
Connectivity Board Problem
The HGP is comprised of five major components; the PQconnect connectivity board, the line
reactor, the tuning reactor, the contactor and the capacitors. The PQconnect PCB contains
diagnostic LEDs. The locations of the LEDs are shown in Figure 16 and their functions are listed in
Table 34: LED Functions below.

Communication Problems
· J5 Communication Header o With the power de-energized from the filter, check wiring leading to J5 header If the user is using a different RS485 converter than the example above, please follow the datasheet for the A & B signals and ground for proper setup
· Ensure the drivers of the RS485 to USB converter is installed to the computer. Simple way of checking while the RS485 converter connected is to go to the device manager and scroll down to ports. There will be a device connected to the ports. If your device is not listed, the user will need to install the correct drivers of the RS485 converter.
· PQvision App Load Defaults o With the RS485 Converter connected to the circuit board o Energize Filter o Open PQvision desktop interface o Go to Settings o Select Load Defaults o Select Apply o Default Modbus settings should be applied. Try connecting to the COM port If this doesn't work de-energize power to the filter and try flipping the A and B signal wires leading to the J5 header of the circuit board.
· Hard Reset Modbus settings (Worst Case) o To perform a hard reset of Modbus settings the user will need to remove jumper J20 with the power de-energized from the filter. Once the jumper is removed connect the RS485 converter to J5 header and energize filter. o Open PQvision o Confirm there is a COM port under Communication and try to connect Note if connecting to the COM port does not work, try flipping the A and B signal wires leading to the J5 header of the circuit board o Load defaults and apply o Save settings and de-energize filter o Connect jumper to J20 o Energize filter o Try connecting to PCB All Modbus settings should be set to default settings at this point If the board doesn't connect after trying hard reset contact TCI Tech-Support

Contactor Problem
Parameter 257 Contactor Status can be used to determine why the PQconnect board is not closing
the tuned circuit contactor. The following tables define what a specific contactor status code value
means and list potential resolutions to allow the contactor to close.
Note that some setpoint parameters require tech level parameter access to be viewable over the serial connection or via the PQvision software. The tech level parameter access key is available above.

Resolution
The PQconnect is presently commanding the tuned circuit contactor to be closed. If the contactor is not closing check the wiring from the PCB J11 control relay header to the tuned circuit contactor and 120VAC control power transformer. The present contactor control mode (feedback parameter 250) is set to Force Open. This control mode will always keep the contactor open. To change the control mode, see setpoint parameter 510. The present contactor control mode (feedback parameter 250) is set to Automatic Load Control and the measured filter load Amps are below the configured close threshold (feedback parameter 270). The contactor will be closed when the filter load Amps exceed the close threshold. The contactor close filter load current threshold can be adjusted via setpoint parameter 570. The contactor close threshold parameter is scaled in units of percent rated nameplate filter current. The present contactor control mode (feedback parameter 250) is set to Automatic kVAR Control and closing the contactor would exceed the max allowable kVAR flowing to the source to be exceeded (feedback parameter 272). The contactor will be closed when the inductive load kVAR minus the capacitive tuned circuit kVAR of the passive filter is below the max kVAR setpoint parameter. The max kVAR setpoint parameter can be adjusted via setpoint 572. The present contactor control mode (feedback parameter 250) is set to External Control and the external command is set to open the contactor. The external contactor control command is wired to the PQconnect PCB header J7 where shorting pins 1 and 2 of that header equal a close command.
The internal state of the external control command can be audited via feedback parameter 320 in bit position 0. If an external contactor close command is correctly being input to the PQconnect board then confirm the J7 header input is configured as the external control command by verifying feedback parameter 321 is set to a value of 2=external command input. If the input configuration parameter 321 is not set to 2=external command input the input configuration can be changed via setpoint parameter 610. The present contactor control mode (feedback parameter 250) is set to No Contactor Mode. No Contactor mode is typically reserved for HGP units that do not include a tuned circuit control contactor. If your HGP unit does include a tuned circuit contactor but the PQconnect is configured to not support a contactor, please call TCI technical support.

The contactor is open due to a filter, filter line, or filter load status detection being detected that is
configured to open the tuned circuit contactor when detected. The PQconnect continuously
monitors the internal conditions of the HGP passive filter and the external conditions of the filter
line and load currents and voltages. Some status conditions, such as tuned circuit overcurrent,
are configured to open the tuned circuit contactor when detected as a self-protection feature.

To reset all status conditions and attempt to re-close the contactor the unit can be power cycled,
a serial command can be sent over the network interface via setpoint parameter 502, or an
external wired reset command can be input to the PQconnect PCB at header J8 where shorting
pins 1 and 2 of that header equal a close command. The internal state of the external wired reset
command can be audited via feedback parameter 320 in bit position 1. If an external reset
command is correctly being input to the PQconnect board then confirm the J8 header input is
configured as the external reset command by verifying feedback parameter 322 is set to a value
of 1=external reset command input. If the input configuration parameter 322 is not set to
1=external reset command input the input configuration can be changed via setpoint parameter

If a minimum time is not enforced between repeated contactor close events the contactor may reclose and apply line voltage out of phase with the residual voltage on the tuned circuit capacitors.
This could cause high currents to flow through the tuned circuit contactor and potentially blow the
contactor protective fuses. The remaining time on the minimum contactor re-close timer can be
viewed on feedback parameter 286.
