System Power-up
NOTE
Before applying power to the system, check that there are no notes in the acceptor. Wait until the
stacker cycles twice before inserting notes.
The stacker punch cycles once at the beginning and once at the end of the power-up self-
calibration sequence. The second cycling of the stacker punch marks the end of the power-up
sequence.
The power-up sequence takes approximately 10 to 15 seconds. Refer to Figure 2-3. The System should not
be disturbed until the sequence is completed. During this sequence, the System firmware does the
following:
- Checks for objects in the note path and if necessary clears the note path.
- Cycles the stacker punch once.
- Calibrates the front sensors.
- Calibrates the dual-density sensor.
- Calibrates the top and bottom TNT sensors.
- Calibrates the String Sensor.
- Checks the DIP switch settings.
- Checks for stacker present. If present, the stacker is cycled and checked for proper rest position.
- Reads chassis and cash box memory buttons (If optional smart system is installed)
