1.6.3 E-Stop Precaution
WARNING
INTEGRATED E-STOP CIRCUIT NOT PRESENT
To Avoid Injury:
• When a QB Expert Alpha controller connects to a tool where a fault can result in personal injury or substantial
damage to property, an E-stop circuit is required. An E-stop circuit must be created in the external electrical
service supply line.
1.6.4 Tool Speed and Torque Scatter Versus Electric Supply
The minimum electric supply voltage required to attain catalog speeds is 104V AC or 208V AC depending which
supply voltage system is used. Supply voltages above these minimums should have NO effect on reducing speed.
Supply voltages BELOW these minimums will reduce maximum free speed proportionally; actual speed should be
the LOWER of the speed command or the maximum attainable speed. Slow Seek and downshift speeds should
not be affected unless they are set close to maximum attainable speed. Similarly torque scatter should NOT be
affected by reduced supply voltages.
1.6.5 Tool Temperature Versus Electric Supply
Supply voltages that remain within recommended limits during the fastening cycle will provide shortest cycle
times and lowest tool temperatures. Tool temperatures on applications with moderate to high prevailing torque
levels and/or low (i.e. soft) torque rates stand the most chance of being negatively impacted by low or “sagging”
