Reflected Power Meter / 0-2.5KW

The reflected Power meter displays the reflected power from the load. The meter receives the signal from the Solid State Amplifier. The Amplifier AGC converts the logarithmic signal from the RF Line Section Slugs (RF Sensors) to linear signal. 

Grid Current Meter  / 0-1A

Displays the Grid current during RF ON. The Grid Current limit is set at the factory based on the type of tube use.

Local / Remote Mode SW

Selects the generator operation in Local Mode to control from the panel switches and in Remote Mode the generator is controlled from the PLC

Knob-1 / RF ON Timer

RF-ON Timer functions in local mode and is activated when the RF output is set ON. The RF powers turns off after the timer times out. The timer is used for reference only.

Knob-2 / RF-Power Control

The power control knob is used in Local Mode only, which sets the amplifier input voltage from 0-10vdc to increase the RF output power. The RF output is set 0 watt when the Knob-2 is adjusted all the way in CCW direction and Max Power when adjusted in CW direction.

Hi-Voltage ON Red PB

The Hi-Voltage ON PB is active only in Local Mode. When pressed the Hi-voltage contactor turns ON the Plate Voltage in two steps (soft start).

Hi-Voltage OFF Amber PB

The Hi-Voltage OFF PB is active only in Local Mode. When pressed the Hi-voltage contactor turns OFF the Plate Voltage.

RF Power ON Red PB

The RF Power ON PB is active only in Local Mode and when the Plate voltage is ON. When pressed, the RF circuit will activate and RF power can be increased only by turning the RF Power control Knob-2 in CW direction (0-10vdc).

RF Power OFF Amber PB

The RF Power OFF PB is active only in Local Mode. When pressed, the RF circuit will deactivate the RF power.

Reset Blue PB

The reset button is active all the time and is for resetting the generator fault conditions or E-Stop condition.

E-Stop Red Mushroom PB

E-stop PB is active in all conditions and intended for emergency shutdown, which is wired in series with the RF welder emergency circuit. When energized it interrupts the hi-voltage to the Plate and turns of the Solid State Amplifier Power. 

Ready-LED / Green or Red

Green - When all generator internal diagnostic circuit conditions are OK after pressing reset PB.

Red - when any of the other LEDs are Red. When LED is red the generator will not turn HV on nor the RF PWR. 

VSWR LED / Green or Red

Green - When reflected power is low..

Red - when reflected power exceeds the factory set limit 10 or 20%. For some applications ONEX can set higher limits to overcome the Hi-REF spike condition errors due to some materials

Overload-LED / Green or Red

Green - When all Plate current is below the factory set limit.

Red - when Plate current exceeds 3.5 A, set at the factory, (for lower power generators the set point may be lower based on the Tube specs).

Arc-LED / Green or Red

Green - When the generator power is ON and there is no Arc or short load to ground signal.

Red - when arc detected during sealing cycle, The output power is immediately turned of to prevent any die damage.

NO-RF Feedback -LED / Green or Red

Green - When Solid State Amplifier turns on and energizes the final stage amplifier it monitors the RF output signal feedback. If the feed back is normal the LED stays green. 

Red - when the RF final output feedback from the line section is not detect the the solid state driver stops the output.

This feature is intended to prevent the RF output incremental rise due to lack of feedback signal, because the SS-Amp AGC role is to maintain the constant power output by increasing or decreasingthe first stage RF signal level.

3 Phase - LED / Green or Red

Green - When all generator input power phases are OK and not swapped or interrupted individually.

Red - when any of the 3-phase power lines does not detect voltage or the phases are swapped. 

Blower-LED / Green or Red

Green - When Blower is ON and the switch detects adequate air flow into the tube section.

Red - when blower circuit is ON but the air flow switch is not energized by the blowing air flow or the blower is not working.

Door Switch -LED / Green or Red

Green - When the generator back door is closed.

Red - when generator back door is open or switch is loose when the door is closed.

AMP-FAN -LED / Green or Red

Green - When Solid State amplifier is ON, the 3 Fans are blowing and the air flow switch (on the opposite side of the amplifier) detects .

Red - when the RF amplifier is ON but Fans are Off or the Fans are ON but the switch is loose and does not detect adequate air flow. 

NO-RF FEEDBACK- LED / Green or Red

Green - When Solid State Amplifier turns on and energizes the final stage amplifier it monitors the RF output signal feedback. If the feed back is normal the LED stays green. 

Red - when the RF final output feedback from the line section is not detect the the solid state driver stops the output.

This feature is intended to prevent the RF output incremental rise due to lack of feedback signal, because the SS-Amp AGC role is to maintain the constant power output by increasing or decreasingthe first stage RF signal level.
