Abstract
Disclosed are systems and methods for protecting an escrow clutch of a self-service terminal. The systems and methods may include actuating a motor of the self-service terminal to cause an escrow clutch of the self-service terminal to spin at a rate. As the clutch spins, a determination as to when a clutch slippage exceeds a preset slippage rate may be made. When the clutch slippage exceeds the preset slippage rate, the motor may be actuated to cause the escrow clutch to spin at a second rate. The second rate may less than the first rate.
Claims14
A method for controlling a self-service terminal, the method comprising:
- actuating a motor of the self-service terminal to cause an input of an escrow clutch of the self-service terminal to spin at a first rate;
- determining when a clutch slippage exceeds a preset clutch slippage, wherein determining when the clutch slippage exceeds the preset clutch slippage comprises:
- determining the clutch slippage by determining when a current draw by the motor decreases by a preset current change;
- and
- comparing the clutch slippage to the preset clutch slippage, the preset clutch slippage being dependent upon a current stage of a financial transaction;
- and
- actuating the motor to cause the escrow clutch to spin at a second rate, wherein the second rate is less than the first rate,
- wherein the preset clutch slippage includes a desired slippage for the escrow clutch when the self-service terminal is receiving notes,
- wherein determining when the clutch slippage exceeds the preset clutch slippage further includes determining that a temperature of the escrow clutch exceeds a preset temperature without an independent clutch temperature sensor.

A self-service terminal comprising:
- an escrow clutch;
- a motor operatively connected to the escrow clutch;
- and
- a controller to control operation of the self-service terminal, the controller operable to cause the self-service terminal to perform actions comprising:
- actuating the motor to cause an input of the escrow clutch to spin at a first rate,
- determining when a clutch slippage exceeds a preset clutch slippage, wherein determining when the clutch slippage exceeds the preset clutch slippage comprises:
- determining the clutch slippage by-determining when a current draw by the motor decreases by a preset current change;
- and
- comparing the clutch slippage to the preset clutch slippage, the preset clutch slippage being dependent upon a current stage of a financial transaction, and
- actuating the motor to cause the input of the escrow clutch to spin at a second rate, wherein the second rate is less than the first rate,
- wherein the preset clutch slippage includes a desired slippage for the escrow clutch when the self-service terminal is receiving notes, and
- wherein determining when the clutch slippage exceeds the preset clutch slippage further includes the controller operable to cause the self-service terminal to perform further actions comprising determining that a temperature of the escrow clutch exceeds a preset temperature without the use of a clutch temperature sensor.
9 more elements
A controller for a self-service terminal comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to:
- transmit a first voltage to a motor of the self-service terminal, the first voltage operative to cause the motor to spin an escrow clutch of the self-service terminal at a first rate,
- determine when a clutch slippage exceeds a preset clutch slippage, wherein determining when the clutch slippage exceeds the preset clutch slippage comprises:
- continuously measuring a current draw by the motor,
- determining when the current draw decrease by a preset current change, and
- transmit a second voltage to the motor when the current draw changes by the value greater than the preset current change, the second voltage operative to cause the motor to spin the escrow clutch at a second rate,
- wherein the second voltage is less than the first voltage,
- wherein the preset clutch slippage includes a desired slippage for the escrow clutch when the self-service terminal is receiving notes,
- wherein determining when the clutch slippage exceeds the preset clutch slippage further includes the controller operable to cause the self-service terminal to perform further actions comprising determining that a temperature of the escrow clutch exceeds a preset temperature without the use of a clutch temperature sensor without the use of an independent clutch temperature sensor.
