the low setpoint. The segment representing the measured tonnage
relative to the high and low setpoints is lighted each time a new
tonnage is displayed.
2.1.1.1 Display of Alarms
Alarms are generated when the System 1100 detects that the measured
tonnage has exceeded a preset value (high setpoint, reverse
setpoint, or machine rating) or in the case of low setpoints, has
not exceeded a minimum value. Alarms are indicated on the System
1100 using the tonnage displays and the bar graphs.
Machine rating alarms are generated when the measured tonnage
exceeds 125% of the channel rating, where the channel rating is the
machine rating divided by the number of channels. Machine rating
alarms are indicated by a flashing tonnage display on the channel
on which the alarm occurred.
High setpoint alarms are generated when the measured tonnage for a
channel meets or exceeds the high setpoint for that channel. High
setpoint alarms are indicated by the top red segment on the channel
bar graph flashing.
Low setpoint alarms are generated when the measured tonnage for a
channel during the stroke does not meet or exceed the low setpoint.
Low setpoint alarms are indicated by the bottom red segment on the
channel bar graph flashing.
Reverse setpoint alarms are generated when the reverse tonnage for
a channel meets or exceeds the reverse setpoint for that channel.
Reverse setpoints alarms are indicated by a flashing reverse
tonnage (reverse tonnages are indicated by a minus sign in the
tonnage display).
