ALARMS
The Standard Roller Apparatus contains up to three system performance alarms: Bottle Speed
Tolerance, Bottle Rotation (optional) and Battery Condition and Backup (optional). Each of these
alarms will show a message on the front panel display. If multiple optional alarms are active, the
operational mode display would flash/alternate between each alarm message.
The front panel
Power Switch
will also serve as an alarm indicator. If running on battery backup, the
power switch will blink at a slow rate (about 1 blink per 2 seconds). If any of the three system alarms
are activated, the power switch will blink at a fast rate (about 1 blink every
½
second).
If the optional Rotation Alarm and Battery Backup package is installed, a front panel Alarm Output
jack is provided for remote monitoring of alarm conditions. Specifications for the front panel Alarm
Output Jack are provided in
section 0
. The alarm pin out for the front panel Alarm Output Jack is
shown below:

Bottle Speed Tolerance
See
section 3.4.3
for the definition and setting of the
Bottle Speed Tolerance
alarm. If the bottle
speed falls outside the set tolerance threshold (+/-) an audio alarm will sound and the display will
show (tOL).
Rotation Alarm (Option)
Two sensors mounted on the belt train, opposite the control housing, monitor pulley rotation of the
unit’s rollers. If a pulley rotation is not sensed within two expected revolutions the
Rotation Alarm
will
activate, and an audible alarm (loud) will sound. The display will show (rOt). To disable this alarm,
change the rAO parameter (included in the
Factory Mode
) from 1.0 to 0.0. This setting will cause the
software to ignore the belt hall effects.
