6.2 Monitoring Functions
The Fusion System is user programmable to select and set the monitoring limits for torque, angle,
time, up to three independent torque rate areas, and special functions describe below.
6.2.1 Peak Torque Monitoring
Torque Monitoring is a continuous process whenever the System is operating. Peak Torque monitor-
ing uses the maximum torque value detected during Fastening.
• In Torque Control method, the Peak Torque High and Low Torque limits are set based upon the
engineering specification for the specific fastener.
