Otis 400 Elevator
41 fault codes documented
Bill Jam
Indicates a bill jam error within the bill validator. This obstruction in the banknote path prevents the validator from accepting or processing bills, leading to transaction failure.
Bill Validator Motor Defective
Indicates a defective motor within the bill validator. This motor is responsible for transporting and stacking banknotes, so its malfunction will prevent bill acceptance and processing.
Bill Sensor Error
Indicates a bill sensor error within the bill validator. This affects the detection and validation of banknotes, potentially causing bills to be rejected or miscounted.
Bill Stacker Full
Indicates that the bill stacker in the bill validator is full. This prevents the acceptance of any further banknotes until the stacker is emptied, stopping cash transactions.
Bill Validator Communication Loss
Indicates no communication with the bill validator for more than 5 seconds. This issue prevents the machine from accepting banknotes, making it inoperable for cash transactions.
Bill Acceptor ROM Checksum Error
Indicates a ROM checksum error within the bill acceptor, suggesting corruption of its firmware or configuration data. This can lead to validation failures or system instability for banknotes.
Card Reader Communication Loss
Indicates no communication with the card reader for more than 5 minutes. This prevents the machine from processing card payments, disabling cashless transactions.
Card Reader Malfunction
Indicates that a particular type of card reader malfunction has occurred, where 'XY' signifies the specific error type. This could be a hardware fault or a processing error preventing card transactions.
Changer Communication Loss
Indicates no communication with the coin changer for more than 2 seconds. This issue prevents coin acceptance and dispensing, rendering the changer inoperable.
Changer Inlet No Coins Sensed
Indicates that no coins have been sensed by the coin acceptor for over 96 hours. This may be due to a blocked inlet, a faulty acceptor, or a lack of use, preventing coin acceptance.
Changer ROM Checksum Error
Indicates a ROM checksum error within the coin changer, suggesting corruption of the changer's firmware or configuration data. This can lead to erratic behavior or inoperability of the changer.
Coin Jam
Indicates a general coin jam within the changer mechanism, obstructing the coin path and preventing normal operation of coin acceptance or dispensing.
Compressor Not Cooling
Indicates that the compressor is not cooling at a rate of 0.5º C per hour or better while active. This points to a performance issue with the refrigeration system, potentially due to mechanical failure or low refrigerant.
Critical Vend Mechanism Error
Indicates a critical vend mechanism error has occurred, specifically that the DMC home sensor has malfunctioned. This sensor is crucial for the proper positioning and operation of the dispenser mechanism, and its failure will prevent vending.
Cup Sensor Malfunction
Indicates that the cup product detect transmitter, receiver, or the oscillator on the cup board has malfunctioned. This prevents accurate detection of cups and can halt vend operations, leading to product delivery issues.
DC Over Voltage
Indicates that the voltage from the power supply was over 45VDC for more than 30 seconds. This points to a power supply regulation issue, which could damage connected electronic components due to excessive voltage.
DC Under Voltage
Indicates that the voltage from the power supply was under 20VDC for more than 30 seconds. This signifies an insufficient power supply or an excessive load condition on the DC bus, potentially affecting multiple components.
Delivery Port Door Error
Indicates that the DMC is reporting a port door error. This usually means the delivery port door is not opening or closing correctly, which can prevent product dispensing and may cause jams.
Delivery Port Sensor Error
Indicates that the DMC is reporting a port sense error. This can be caused by obstructions blocking the port's LEDs or a malfunction of the port's detection components, preventing delivery detection.
Generic Vend Mechanism Error
Indicates a generic error within the vend mechanism's delivery system. This can encompass a broad range of issues affecting product dispensing, requiring further investigation.
Coin Acceptor Disconnected
Indicates that the coin acceptor is unplugged, leading to a complete inability to receive and validate coins. This will prevent any coin-based transactions.
Door Switch Open
Indicates that one or both of the vender's door switches have been open for more than one hour. This can be caused by a physical obstruction, wiring issue, or a faulty switch, potentially leading to operational lockout.
Excessive Escrow Attempts
Indicates that more than 255 escrow attempts have occurred since the last coin was successfully accepted. This could be due to repeated coin rejections, a sensor issue, or an obstruction in the escrow path.
Health Safety Limit Violated
Indicates that the health safety limit temperature has been violated. This is a critical error, as it means the product storage temperature has exceeded safe limits, potentially compromising product integrity and safety regulations.
Heating System Not Heating
Indicates that the heating system is not heating at a rate of 0.5º C per hour or better while active. This suggests a performance issue with the heating system, potentially impacting product temperature control.
Coin Inlet Blocked
Indicates two coins were sensed at the inlet sensor but failed to make it to the changer within 10 seconds. This suggests a blockage or malfunction in the coin path between the inlet and the changer.
Coin Inlet Sensor Blocked
Indicates the machine’s coin inlet sensor has been blocked for more than a minute. This is an optional component not installed on all venders and prevents coin insertion into the system.
Low Coin Acceptance Rate
Indicates a low coin acceptance rate, specifically that more than 20% of the last 255 coins processed were identified as slugs. This suggests issues with coin validation or slug detection.
Coin Misrouted
Indicates a coin had been improperly routed within the changer. This can lead to coins ending up in the wrong tubes, jams, or incorrect inventory counts.
No Temperature Pulldown
Indicates an inability of the refrigeration system to reach the set point temperature. This implies a significant failure in the system's capacity to cool down the internal environment, affecting product storage conditions.
Cash Box Open
Indicates that the cash box is detected as open. This is typically a security alert or an indication that the cash box sensor is faulty, preventing secure operation.
RAM Checksum Error
Indicates that the machine setup information stored in RAM has been corrupted. This can lead to incorrect machine operation or configuration issues, as no test is available to verify the checksum internally.
Selection Switch Stuck Closed
Indicates that a specific selection switch (identified by XX) has been detected as closed for more than 15 seconds. This implies a stuck key or a faulty switch on the keypad, and will prevent navigation of the service menu.
Incompatible System Scale Factor
Indicates that one of the credit peripherals (e.g., changer) has introduced an incompatible scaling factor, leading to incorrect credit processing or system miscalibration.
Refrigeration Temperature Sensor Error
Indicates an unplugged or faulty temperature sensor within the refrigeration system. This prevents accurate temperature readings for refrigeration control, potentially leading to incorrect cooling or heating.
Refrigeration Too Cold
Indicates that the refrigeration temperature is 1.5º C below the compressor cut-out setting, suggesting the unit is overcooling. This can affect product integrity and potentially damage components.
Refrigeration Too Hot
Indicates that the refrigeration temperature is 1.5º C above the compressor cut-in setting, suggesting the unit is not cooling sufficiently. This can compromise product integrity and safety.
Coin Tube Jam
Indicates a coin tube jam error for a specific coin type (XX). This obstructs the flow of coins within the changer's tubes, preventing proper dispensing or storage for that coin type.
Changer Tube Sensor Error
Indicates a tube sensor error within the coin changer. This affects the proper detection, sorting, and dispensing of coins in the tubes, potentially causing miscounts or jams.
Universal Satellite Device Communication Loss
Indicates that the Universal Satellite Device (DMC) is no longer online. This means communication between the main controller and the DMC is lost, impacting peripheral control and system functionality.
Unassigned Product Cell
Indicates that a specific product cell (identified by XX) is unassigned in the machine's configuration. This means no product is configured for that cell, and it cannot be sold.
