Sequencer

Group 2..6 on -Group turn on delay.

• < —- > – sequencer will not trigger this group. (This group control can also be set in commutation menu).
• Trigger on -Trigger turn on delay. < —- > – sequencer will not change trigger output state. (Also trigger output control can be set in commutation menu)
• Aux control -Additional option to start sequencer. See Trigger options list for details.
• Next -> -go to next page
• Group 2…6 off -Group turn off delay. < —- > – sequencer will not trigger this group. (Group control can also be set in the commutation menu).
• Trigger off. – Trigger turn off delay. < —- > – sequencer will not change trigger output state. (Trigger output control can also be set in the commutation menu)
• Aux control2 -2nd additional option to start sequencer. Go to Trigger options list for details.

Control

• Group 1 current: -Current drain from group 1. Group 1 must be on to let this function work. go to commutation menu to set it.
• On threshold -The amount of current to turn on assigned function. < I Group1> must be assigned to any function in commutation or sequencer menus. 0 – function is disabled. Group 1 must be set always on to let this function work.
• Off threshold -Assigned function will be turned off below this value. < I Group1> must be assigned to the function in commutation or sequencer menus. 0 – function is disabled. This function value mast be lower than “On threshold”.

How to set threshold:

1. Turn On device connected. Set on threshold a little less than current consumption value. If console turn on will be unstable set it one step less.
2. Turn connected device into standby mode. Set off threshold a little more than current consumption value. On threshold must higher than the off threshold.
   • RS232 address -RS232 address for control system.
   • RS232 terminal -terminal for RS232 test.
   • Ethernet terminal -terminal for Ethernet test *
   • Ethernet ECO -turn off Ethernet power if all groups are off*

Available if the optional Ethernet module is installed. The Ethernet module is not included as standard kit.

Save

Select ‘Save’ to save the settings made in the menu. If you do not save your settings, they will reset to previous values after on/off or a power fault reset. The saved settings will come into effect after exit from the menu.

Display

1. Mains voltage sine wave cut in percent – represent the load of the building mains cables.
   • 4% or more – poor wires or wires overload.
   • 6% or more – a critical wiring condition.
2. Sequencer on state indicator – Appears after Sequencer was started and next button press will lunch sequencer turn off sequence.
3. Voltage flicker – voltage pick fluctuation for one minute. High flicker can cause connected devices fault even with normal voltage. 5V or higher – high stress to connected devices. May reduce life of the connected devices. 11V or more – there is a risk of damage to the connected devices. It is recommended to call professional electrician for help
4.  Mains frequency – indicate the load of the national power system.
   • 49,95Hz/ Гц or less – heavy load.
   • 49,90Hz/Гц – power system critical situation.
5. Filter mode. See filtering section of this manual.
   • filter + dumper.
   • filter
6. Grounding indicator. Appears in case of grounded console connection. If “!” is shown it means that there is critical connection issue. Please refer that console is connected according to connection diagram (13).
7. DC filter state.
8. DC over mains value – indicates a mains voltage unbalance. DC forces power transformers to make more noise. Usually after value of +-50mV transformers starts to make noise. By default, the console turns on the DC filter if the value is more than +-60mV during 20seconds. The settings can be changed in the filtering section on the menu.
9. Wi-Fi indicator. Appears during connection or in case of a connection error. After successful connection there will be no indication.

Filtering

Hi-Fi High Current filter section:
This is designed for Hi-Fi devices and high-power amplifiers and features a special design with low output impedance to reduce device to device interference. Wide cooper traces provide current to amplifiers without limitation. Because the filter construction avoids any resonances this filter can do filtering in the audio range without adding distortion and additional noise. Also, our unique filter design allows you to change the filtering parameters yourself. The filtering options can also be controlled remotely.

There are 3 filter modes

1. Minimum filtration – in this mode the minimum filtering required for device protection is applied only.
2. Maximum filtration – Maximum filtration for high noise filtering.
3. Filtering with dumper – this provides less filtering but introduces better resonance dumping and reduces noise generation by connected devices themselves. This also reduces device to device interference.

Filtering can be setup in a menu:

• Filter – Minimum filtering.
• Filter – Maximum filtering.
• Filt. Dumper – Filtering without dumper.
• Filt. Dumper – Filtering with dumper.
• Filt. Dumper comes in to play if Filer option is turned on only.

If any other option is selected as trigger, the filter state will depend on the state of that option.

Hi-Fi High Current DC filter:

By default, the filter is in automatic mode and will be applied if the DC value is more then 60мВ during a 20 second period. Settings can be changed in the menu. Constant states are available as well. In case an amplifier with a switch mode power supply is connected, the DC filter must be turned off. To verify power supply type contact amplifier manufacturer details.

General filter section

This filter section is for devices with switch mode power supplies. Inductors made of superior nanocrystalline material provides very high filtering with small losses and block noise from leaking into the Hi-Fi section. The Filter can work well in the audio range because resonances are avoided in our filter design. It is recommended not to connect devices into the audio signal path with switch mode power supplies (amplifiers are an exception). Please contact the device manufacturer to verify the power supply type. Example of such devices: TVs, settop box, external PSU from small/mobile devices, turntable motors, PC’s. Audio related devices with switch mode power supplies can be connected to both filter types. The most appropriate filter can be selected by doing a listening test. A mechanical dumper PCB with filters is fitted in the console to avoid influence by mechanical noises. This removes potential feedback from speakers.

Protection

The POWERGRIP YG-3 Pure Power console is equipped with high grade protection. It consists of three levels:

1. Filter – blocks noise and small voltage spikes.
2. MOV protection – Absorbs high voltage spikes.
3. Relays – turn off power if voltage is over a high limit or if the MOV is overloaded.

You can therefore be sure that mains troubles will not damage your equipment. The console itself can continuously operate at voltage up to 320V. In case the voltage is more than 320V a simple fuse replacement will be needed.

Proper mains connection system

The YG-3 detects the existence of the ground and the proper connection phase. In case ground exists, and the YG-3 power plug is connected with the wrong phase, operation of the unit will be blocked. If grounding doesn’t exist, or the power line does not comply with TN standard this function is not available. In this case you need to connect YG-3 as shown on diagram 13 by using a phase detecting tool.

Antenna grounding connector

In case an antenna is used in your system it is important to use the supplied antenna grounding cable. Failure to do this can reduce filtering quality and void the protection function. Connect the cable from the kit with the YG-3 grounding terminal (11), then connect the antenna to the connector on the other side of the cable. The cable is not directional.
