6.1.11 When the power is turned on, the alert
Ioport Jammed
appears on the
control panel display, and you do not hear a whining sound for several
seconds before the alert occurs.
During the power up sequence, the I/O port (if present) is driven back to its home po-
sition above the magazines. If the motor is operating but the I/O port is not moving, it
will make a loud buzzing sound. Failure to make this noise indicates one of the follow-
ing causes:
1.
The cable from the Executive PCBA to the I/O port PCBA is damaged or discon-
nected.
2.
The I/O port motor cable is damaged or disconnected.
3.
The unit is configured for an I/O port, but no I/O port is installed.
4.
The I/O port motor has failed.
5.
The Executive PCBA is damaged.
6.1.12 When the power is turned on, the alert
Ioport Jammed
appears on the
control panel display, and you do hear a whining sound for several
seconds before the alert occurs.
During the power up sequence, the I/O port (if present) is driven back to its home po-
sition above the magazines. If the motor is operating but the I/O port is not moving, it
will make a loud buzzing sound. This condition indicates one of the following causes:
1.
The I/O port mechanism is binding, due to misalignment of the guides.
2.
The Carriage is parked in front of the I/O port, with a cartridge that is still in the
I/O port slot engaging the grippers on the Handler.
3.
The metal vane on the I/O port carriage is not obstructing the light beam of the
I/O port Home Sensor.
4.
The I/O port Home Sensor opto-interrupter pair is bent or damaged.
5.
The I/O port mechanism is jammed, due to a mechanical obstruction, or it is
binding against a stop.
6.
The I/O port mechanism is binding, because the leadscrew shaft coupling was set
with too much compression.
