MALFUNCTIONS WITH DIAGNOSTIC MESSAGE
Error Code Er 1: Cause: Reference voltage is outside the limits, incorrect supply voltage
Solution: Notify the service department
Error Code Er 2: - Cause: Data loss (settings) or control switched on for the first time
Solution: Re-enter the settings data - If error occurs frequently, notify the service department
Error Code Er 3: - Cause: Data loss in EEPROM (set-up settings)
Solution: Select operating mode 'Calibrate', error will disappear - If error occurs frequently, notify the service department
Error Code Er 4: - Error in pressure measuring system:
Cause: Pressure sensor is defective or line to the pressure sensor is clogged
Solution: If error happens often, replace the pressure sensor
Cause: Vacuum valve was <700 mbar during "close cover"
Solution: If error occurs frequently, notify the service department
Note: The machine can operate further if the pressure setting is set to '999' and the evacuation is only performed based on time
Error Code Er 6: - Because the pressure no longer dropped, the set pressure setting was not reached after an additional minute and the packing process was cancelled:
Cause: The pressure settings is below the pressure achievable by the pump
Solution: Increase the pressure setting
Cause: Leak in the system (seal or hose)
Solution: Replace defective parts
Cause: Product with a high percentage of water (eg. fresh meat)
Solution: Increase the pressure setting
Error Code 67: - Cause: Vacuum pump does not switch off
Solution: Notify the service department
Cause: Ventilation valve does not open
Solution: Notify the service department
Error Code 68: - Cause: No gas available or near end
Solution: Check inert gas or ensure there is sufficient gas supply
Cause: Stop valve for the gas supply closed
Solution: Open the stop valve for the gas supply
Cause: Gas hose has a kink in it
Solution: Remove the kink in the gas hose
Cause: Value for the gas flushing pressure is set such that it cannot be reached
Solution: Correct the value for Gas flushing pressure
Cause: The vacuum sensor is incorrectly calibrated
Solution: Notify the service department
Cause: Vacuum sensor is defective
Solution: Notify the service department
Cause: Gas valve does not open
Solution: Notify the service department
Error Code 69: - Cause: Value for the Evacuation pressure is set so low that it cannot be reached
Solution: Correct the value for Evacuation pressure
Cause: Vacuum hose between the chamber and the vacuum sensor is clogged, missing or leaking
Solution: Notify the service department
Cause: Vacuum hose is loose, leaking or clogged
Solution: Notify the service department
Cause: Chamber lid gasket not air-tight
Solution: Notify the service department
Cause: Vacuum sensor is defective
Solution: Notify the service department
Cause: Vacuum pump was not being triggered or the vacuum pump is defective
Solution: Notify the service department
Cause: Vacuum pump leaky
Solution: Notify the service department
Cause: Filter in the line to the vacuum sensor is dirty and blocked
Solution: Notify the service department
Error Code 80: - Cause: Leak in hose connections
Solution: Notify the service department
Cause: Leak in vacuum hose
Solution: Notify the service department
Cause: Leak in vacuum sensor and associated line is leaking
Solution: Notify the service department
Error Code 81: - Cause: Sealing diaphragm leaks
Solution: Notify the service department
MALFUNCTIONS WITHOUT DIAGNOSTIC MESSAGE
Machine does not run: - Cause: Machine is switched off
Solution: Switch on the machine
Cause: Power plug is unplugged
Solution: Plug in the power plug
Chamber lid does not remain closed despite pump running: - Cause: Chamber lid not pressed down for long enough
Solution: Press chamber lid closed more firmly and for longer
Cause: Chamber lid gasket is dirty
Solution: Clean the chamber lid gasket
Cause: Chamber lid gasket is damaged
Solution: Notify the service department
Seal seam not airtight/pack is slack: - Cause: Sealing time is set incorrectly
Solution: Correct the sealing time
Cause: Target pressure value incorrectly set
Solution: Correct the target pressure value
Cause: Pouch neck is clamped by chamber lid
Solution: Insert the film pouch so that the pouch neck lies within the chamber.
Cause: Seal seam is dirty
Solution: Keep sealing bar and film pouch clean
Cause: Pack not air-tight
Solution: Use a new film pouch
Cause: Film pouch not suitable
Solution: Use a film pouch suitable for sealing
Cause: The sealing force is not sufficient
Solution: Test settings. Sufficient sealing force is only achieved if the target pressure is set under 400 mbar.
Cause: Sealing bar damaged
Solution: Notify the service department
The target pressure value is not reached: - Cause: The set target pressure is not achieved (e.g. product contains water)
Solution: Set a higher target pressure
Cause: Chamber lid gasket is dirty
Solution: Clean the chamber lid gasket
Cause: Insufficient oil quantity or oil in the vacuum pump is too old
Solution: Refill or replace oil
Cause: Chamber lid gasket is damaged
Solution: Notify the service department
Cause: Evacuation system is not airtight
Solution: Notify the service department
Odour or smoke: - Cause: Air de-oiling element defective
Solution: Notify the service department
Cause: Oil check valve of vacuum pump is blocked
Solution: Notify the service department
