15) COMP signal will be generated for 0.1 second before stopping.
16) Manually turn OFF electric screwdriver with start lever.
17) Remove the work piece and cancel the SET signal.
* Operations after completion of screw tightening.
Count reset will be performed via the auto-reset function after completion of
screw tightening. The unit will be in standby mode until the SET signal from the
following Work Set is entered (the electric screwdriver will remain unusable while
in standby mode).
<Caution>
•
In order to allow the electric screwdriver to become usable while entering the initial SET
signals, the ON and OFF SET signal during the Work Set Timer has no effect on the
operation of the ER BZ signal.
•
The ER BZ signal is only generated after the Work Set Timer has been completed and
the SET signal changes from ON to OFF.
•
Reverse loosening with the electric screwdriver after the final screw has been tightened
is only possible while the Work Reset Timer is operational and the Work Complete
Buzzer is sounding, and only if loosening of the screws is required after the final screw
of the work piece has been tightened.
(Work Reset Timer VR can be adjusted from 0.1 to 3 seconds)
•
Any reverse rotation at this stage will be considered as an error in the tightening se-
quence. The slightest reverse rotation (regardless of the Reverse Rotation Count Timer
settings) will result in a count-up.
•
Normal rotation tightening is possible while the Work Complete Buzzer is sounding,
however count-down will not be performed.
•
Counting errors may result in using PS-type (push start type) electric screwdrivers to
tighten screws freely, or repeatedly turning electric screwdrivers ON and OFF for short
times for screws with short threads.
Contact our Sales Department if you wish to tighten screws in these situations.
