4.2.4.3 Permissible equipment for BT356/SB356
A tightening channel consists of the following components:
• Tightening spindle
or
ErgoSpin hand-held nutrunner connection cable
• Control unit
• Servo amplifier
If the appropriate control and servo components are installed, both tightening spindles and ErgoSpin
hand-held nutrunners can be connected to and operated on the SB356 system box and the BT356 card
rack field.
Mixed operation of tightening spindles and ErgoSpin hand-held nutrunners on a system box or card rack
field is possible at any time.
Not every configuration is permitted, due to the fact that the power consumption of the servo amplifier
depends on the type of tightening spindle or ErgoSpin hand-held nutrunner that is connected. The
maximum permissible peak current for up to six tightening channels in the card rack field or system box is
140 A.
This is why you may only install components, total power consumption of which does not exceed 140 A.
You can find an overview of the power consumption of tightening spindles and ErgoSpin hand-held
nutrunners in the table below:
4.2.5 Connected load
4.2.5.1 Compact system
The CS351 compact system is designed as follows:
• Nominal voltage: 120/230V
• Nominal current: 10/5.2A
• Nominal power: 1200 VA
• Peak power: 4800 V
4.2.5.2 Modular system
The connected load needed for a card rack field or system box depends on the number and size of the
tightening channels to be operated. Calculations should be based on fully equipped card rack fields/
system boxes, as the necessary connected load will still be available if the equipment has been modified.
