REV. Pushbutton
For a Single System, while this push-button is depressed, the nutrunner rotates at Reverse 1 Speed
(Data-No. 406) in the opposite direction to the programmed fastening direction for the Parameter selected
via the PLC “Work Select” inputs.
For a Multi System, the function of the Master (Master Spindle) and Slave (Slave Spindle) are different.
・
Master … All of the connected spindles including Master run in reverse (Reverse 1 Speed).
・
Slave …..Reverse pushbutton does not function.
････
With the multi system, spindles may be bypassed (not selected to run) in the
sequence program. Spindles not set to run in a selected sequence, will not run
or cycle
CAL Pushbutton
Depress this push-button to obtain the CAL voltage level from the tool pre-amplifier. This level is
compared to the data stored in memory. If the difference is within the allowed range the JUDGE LED
will light in Green, otherwise the JUDGE LED will light in Red. The calibration voltage level is converted
to the full-scale torque, according to the parameter setting (Data-No. 100) and is shown in the "DATA"
display.
For the Master (Master Spindle) of a Multi System, all of the transducers of connected spindles,
including the Master, will be checked.
In addition, when the CAL switch is pressed in the state where D-No. 1 [Torque Voltage Value
Indication] of the real time mode (PAGE 8-7) is indicated, the value converted in terms of the potential
difference of approximately
Δ
3.75V is indicated on the upper digits of the display.

・
Do not press the CAL button during fastening operation. The sudden stopping of
the tool may cause workpiece damage.
RESET Pushbutton
When the RESET push-button is pushed (when not operating), a value close to “0” is indicated on the
upper digits of the display and the fastening result output signals are cleared.
At the same time, the
Zero level of the torque transducer will be checked. If it is within the acceptable range, the JUDGE LED
will light in Green. If it is not within range, the JUDGE LED will light in Red.
If the RESET push-button is pushed while fastening, the fastening operation is stopped and the output
signals of fastening result and LED displays will be reset.
For the Master (Master Spindle) of a Multi System, all connected spindles, including Master, will be
affected (fastening halted, resetting of outputs/results and the checking of the origin level of transducer).
If all of the connected spindles zero level is within the acceptable range, the MULTI LED will light in
Green. If it is not within range, the MULTI LED will light in Red.
