Maintenance is limited to keeping the front panel and fan filters clean.
Use a soft cloth and window cleaner or mild detergent to clean the front panel. Do not use solvent; solvent will damage the plastic panel overlay.
Clean the fan filter located on the back of the power supply and the filter on the end of the sealing coil. Filters should be cleaned with plant air or vacuumed occasionally. Check the fans behind the filters for accumulation of dust. Remove any dust carefully with dry compressed air. (Disconnect incoming power before cleaning.)
Lubricate the jack screw that carries the power supply and sealing coil up and down during height adjustments. Lubricate the wheels on your portable cart (if applicable).

Pillar Technologies Capsealing Equipment - Unifoiler Troubleshooting
PROBLEM | POSSIBLE CAUSE | SOLUTION |
|---|---|---|
| Undervolts Fault | DC Bus Fuse open | Open capsealer cabinet. Press Start, observe red LED on snubber board, located on the heat sink, on the back wall of the cabinet. If Red LED is lit, fuse is OK. |
| Sealing Coil | With power off, remove wires #1101 and #1104 from TB2 (Output Transformer). Power up and press Start. If power meter begins to ramp up, the sealing coil is bad. Damage to the capsealer may occur if allowed to run without a coil for longer than 3 seconds. | |
| Inverter not firing | Using a DC voltmeter, measure the voltage at TP13 on Main Control Board. With circuit breaker on, TP13 should read +1 VDC. Press Start, TP13 should rise to +8 VDC for approx. 1 second, then drop to +1 VDC, as Undervolts Fault lights. Measure voltage on TP14, repeat procedure. If either TP13 or TP14 fail this test, the inverter is not firing. See “Undervolts…Inverter not firing”. | |
| Loose wire or connector | With power off, pull on each wire to ensure it is tight. Push on each connector, to ensure it is seated properly. | |
| Power Interface Board | If the inverter is firing and no other cause can be found, replace Power Interface Board. | |
| Undervolts… Inverter not firing(failed step 3 above) | Main Control Board | With power off, (Ensure DC Bus is bled down)Disconnect wire # 7 from bridge rectifier. Disconnect quick disconnect terminal from Gate Drive Board. With a DC voltmeter, measure voltage on TP18, on Main Control Board. Power up. Read +15 VDC. Press Start. Voltage will drop to +8 VDC for one second then return to +15 VDC. Press Stop. Measure voltage on TP19, Repeat procedure. |
| Gate Drive Board Note 1. | With power off, and wire #7 disconnected from the Bridge Rectifier, Reconnect terminal to Gate Drive Board. Carefully disconnect wire # 16 and #4, and #17 and #10 from the Gate Drive Board terminal. Connect a DC voltmeter from #16(-) to #4(+). Turn on CB, measure -14 VDC. Press Start, voltage should rise to -1 VDC for 1 second then drop back to -14 VDC. Repeat step measuring wire # 17(+) and #10(-). Reconnect gate wires in the correct order. | |
| IGBT Failed | See procedure for checking IGBT. | |
| Power Interface Board | Replace Power Interface Board. | |
| Output Current Fault | Power Interface Board | Replace Power Interface Board. |
| Main Control Board | Replace Main Control Board. | |
| Sealing coil | Replace the Sealing Coil. | |
| Overvolts Fault | Loose connection at output transformer | With power off, tighten all connections. |
| Open connection in sealing coil | Remove the box cover on top of the sealing coil. Check the condition of the wires that connect the power connector with the capacitor bank. If wires are scorched, replace the power connector. | |
| Input Voltage | Measure the input supply voltage. Then refer to the interconnection diagram included in the owner’s manual. Wire the main disconnect according to what the input voltage measured. | |
| Power Interface Board | Replace the Power Interface Board. | |
| Main Control Board | Replace the Main Control Board. | |
| Low Impedance.. Unable to achieve full power | Low input voltage. (It is normal for Low Impedance to be lit before Start button is pressed) | With capsealer running at maximum output, measure input voltage. If voltage is below 205 VAC refer to the interconnection diagram located in the owner’s manual. |
| Main Disconnect not wired properly. | There is a connection for 230 VAC and a connection for 208 VAC. Refer to the interconnection diagram located in the owner’s manual. | |
| Low Impedance flashes as bottles pass under sealing coil (may have Trouble Sealing bottles) | Output transformer not properly tapped | With power off, Re-tap output transformer. One of the output leads should always be on H1, move the other wire to a lower tap (i.e. from H4 to H3) |
| Low voltage problems | See “Low Impedance… Unable to achieve full power” above. | |
| Power Interface Board | Replace Power Interface Board. | |
| Main Control Board | Replace Main Control Board. | |
| Sealing Coil | Replace the Sealing Coil. | |
| High Temp Fault | Insufficient cooling or high ambient temperature. |
|
| Main Control Board | Place a jumper between TBF-8 and TBF-9 (wires #47 and #48) on Main Control Board. If fault does not reset, replace Main Control Board. Do not attempt to operate capsealer with this jumper in place. Damage to unit may occur. | |
| Thermal Switch | Replace the Thermal Switch. | |
| The K1 contactor engages…No output… No red fault lights lit | Interlock | Check the interlock circuit to make sure all are met. Refer to the electrical schematics included with the owners manual. |
| Sealing coil | With power off, remove wires #1101 and #1104 from TB2 (Output Transformer). Power up and press Start. If output meter begins to ramp up, the coil is bad. Damage to the capsealer may occur if allowed to run without a coil for longer than 3 seconds. | |
| Main Control Board | Replace Main Control Board. | |
| Power Interface Board | Replace Power Interface Board. | |
| Stalled Bottle | Setup | A proper setup needs to be achieved according to the owner’s manual. |
| Fiber Optic Sensor | Check the condition of the fiber optic cables. They should be at the same height on corresponding brackets. With nothing in between the sensors the amplifier should be a green light only. When blocked the red light will illuminate. If the fibers are aimed correctly with no lights, wiggle the fibers at the brackets to see if there is a change on the amplifier. The fibers may need to be replaced. | |
| Encoder | With the cap sealer in the setup mode the three digit led will display the encoder reference. If the number of pulses varies more than five to ten pulses plus or minus check the mounting of the encoder. If the meter displays zero ensure that dip switch #1 on the Display Board is turned on. If dip switch #1 is on, replace the encoder. | |
| Stalled Bottle occurs when the bottle reaches the exit bracket. | The orientation of the sensor group may be wrong. If the sensors are arranged that the foil sensor is located on the entrance bracket and there is no reject device to remove the bottle before it reaches the exit bracket this will occur every time a missing foil or loose cap is detected. A rejection device must be installed to reject the bottle before the exit bracket or the orientation of the sensors must be changed. |
Pillar Technologies Control Panel Operation
Inverter
The disconnect switch is located on the rear of the cabinet. This switch removes all power from the inverter cabinet. A circuit breaker, which is also located on the rear of the cabinet, protects the internal circuitry from damage. The circuit breaker also supplies power to inverter components and options.
The locally mounted operator panel puts all the operator functions right at the point of operation including diagnostic indicators, status indicators, operating set points, and a digital meter, which indicates output power. The membrane control panel is soft touch with easy to adjust controls.
These few minutes of upkeep are factory recommended every few months. Simply run through the check-list for your type of sealer(s).
Diagnostic Lights
Setup – Indicates that the system is in the set up mode for the bottle and cap detection option. Refer to the section on detection systems for further detail.
Inverter On – Indicates that power is being supplied to the sealing coil. When indicator is flashing, this means that the auto start contact is open and that the inverter is in standby mode and ready to turn on when the auto start contact closes.
Alarm Fault – Lights when the coil output has dropped below the threshold set by the alarm set point on the panel. This is used to indicate that the inverter is not supplying the desired power to the coil. In such a case, proper sealing may not be ac
complished. This light shows that the alarm circuitry is active.
Impedance High – If this light should illuminate when the inverter is in Stop mode, it does not indicate a problem. If it illuminates while the inverter is running, there may be a problem inside the inverter or coil. Typically this indicates that a capacitor within the coil assembly has opened up. In this event, please contact Pillar Service.
Impedance Low – Indicates that an impedance mismatch has occurred. This condition occurs when the load on the inverter is higher than it can deliver. When this occurs, the output transformer tap may need to be changed to deliver a lower voltage to the sealing coil. for more information. Note: If this light illuminates when the inverter is in Stop mode, it do es not indicate a problem.
High Temp- Indicates that the power transistors inside the inverter are not receiving sufficient cooling. The inverter will shut down to prevent the unit from overheating. If this light illuminates, you should call Pillar Service.
Reject Fault – Indicates that the reject verification sensor did not sense a bottle moving into the reject tray. Also illuminates in SETUP mode and the reject verification sensor is blocked.
Current Trip – Indicates that a short circuit has occurred between the inverter and the coil. The inverter will shut down to protect the output circuits. If this light illuminates, you should call Pillar Service.
Under Voltage Trip – Indicates that the supply voltage to the inverter has dropped (as in a brownout). The inverter will shut down to prevent the inverter from drawing excessive current. Check the supply voltage.
Over Voltage Trip – Indicates that a voltage surge or other situation has caused an over-voltage condition within the inverter. The inverter will shut down to protect itself.
Stalled Bottle Fault – When this light is illuminated it is a warning that a Stalled Bottle condition was detected at the sealing coil. Also lights when rejected bottle button is pressed. Refer to the Stalled Bottle section in this manual for further information on this system. Note: Only applies to systems that include this option.
Loose Cap Fault – When this light is illuminated, it indicates that a cap was detected which is not fully seated on the container or is not threaded evenly causing a fault condition. Also lights when rejected bottle button is pressed. Refer to the Loose Cap Detector section in this manual for further information. Note: Only applies to systems that include this option.
Missing Foil Fault – When this light is illuminated, it indicates that a container passed under the sealing coil that did not have a liner installed, and was not properly sealed. Also lights when rejected bottle button is pressed. Refer to the Missing Foil Detector section in this manual for further information. Note: Only applies to systems that include this option.
Zero Speed Fault – When this light is illuminated it is a warning that a Zero Speed Condition was detected at the conveyor. If enabled, the Zero Speed Fault LED will illuminate when there is a zero speed fault instead of the STALLED BOTTLE FAULT. Note: Only applies to systems that include this option.
The locally mounted operator panel puts all the operator functions right at the point of operation including diagnostic indicators, status indicators, operating set points, and a digital meter, which indicates output power. The membrane control panel is soft touch with easy to adjust controls.
These few minutes of upkeep are factory recommended every few months. Simply run through the check-list for your type of sealer(s).
Operator Controls
LED Display – Shows the power level in percent being delivered by the inverter to the sealing coil.
Power – When pressed the display will read the requested power set point and if the inverter is running it will return back to actual power when released. Active when green indicator is lit on button.
Alarm Set – Pressing this button allows the operator to view the Alarm Set Point on the display and change as required. Active when green indicator is lit on button.
Total Bottle – Indicates the total number of containers that have passed through the sealing coil. Not available without the optional detection system. Reset by holding the button for 5 seconds.
Rejected Bottle – Indicates the total
number of rejects due to a stalled bottle, loose cap, or missing foil fault. Not available without the optional detection system. Reset by holding button for 5 seconds.
Total Run Time – Indicates the total number of operating hours on the system. Reset by holding the button for 5 seconds.
Power Set Point – Digital entry of the percentage of output power. This setting will control the amount of heating induced in the bottle caps. To change the setting, press the up or down button next and set for the appropriate level on the display.
Alarm / Time Set Point – Digital entry of the alarm threshold. If the actual power output to the coil falls below this setting, the alarm circuitry will be activated. This is sometimes called the “loss of seal” condition. Note: Set the alarm to “0” if the alarm function in not needed. Digital entry of the hand held coil “on” time. The “on” time (duration) is adjustable anywhere from 0-10 seconds.
NOTE Always set the alarm set point below that of the power setting. If the alarm setting is the same or higher than the power setting, the alarm circuitry will activate.
Start – Energizes the inverter causing selected power to be delivered to the sealing coil.
Stop – De-energizes the inverter to cease delivering power to the sealing coil. This does not shut off the internal circuitry of the inverter. Also is used as a reset for the under voltage trip, over voltage trip, and current trip.
Reset – Pressing this button after a stalled bottle, loose cap, or missing foil condition has occurred will enable the inverter as long as the fault no longer exists. Note: Only applies to systems that include these options.
The reset button also serves as an alarm silence. If the loss of seal alarm is used, pressing this button will silence the loss of seal alarm. Note that the alarm can only be silenced if the capsealer is stopped.
The first push of the reset button will silence the alarm. The second push of the reset button will clear any fault that is present.
Run/Setup – Pressing this button will toggle between the run and setup mode for the stalled bottle detector. The setup LED will also light when in the setup mode.
