Troubleshooting

When the system is switched on, the servo
amplifier recognizes the size of the tightening
spindle. If the combination is not permitted, a
corresponding error message is output to the
tightener controller. It is then not possible to
start a tightening sequence.
Malfunctions and information on errors are
displayed by the LEDs on the front panel (see
section "Displays and operating elements"
on page 21) and in the tightening system,
e.g. in the BS350.
