Should the Test Bolt form be closed, or ToolsTalk PowerMACS be disconnected from the TCs, while a
cycle is executing then the cycle is terminated using Machine stop.
Note! When running a station from the Test Bolt form the PowerMACS PLC outputs MODE and
BOLTCONTROL are overridden. This means that PLC inputs that depend on these, for example
BOLTSTATE, may have values that do not correspond to the values of MODE and/or
BOLTCONTROL. To detect these situations in the PLC use the input CURRMODE and
TESTBOLT_ACTIVE. The first one always reflects the mode currently known by the station and the
second one is set True whenever the Test Bolt form is opened against the station in questions.
Also, when the Test Bolt form is closed, or you switch to another station, the station is updated with
the value of the PLC outputs MODE and BOLTCONTROL.
You can run the test in Single Run mode, in Program mode or in Mode table mode. You select which by
activating the corresponding button.
Single Run mode
In Single Run the bolts are run once to a specified Target defined either by Torque , Angle or Current .
Use the controls in the Run conditions frame to define the direction and speed to use when executing the
step.
Speed can also be specified as target. If so, then the bolt(s) will run continuously with speed and direction
as set by the Run conditions.
When target is reached, or once a second if running speed, a number of measured values are displayed in
the
Result frame. Except for the peak torque value all values are sampled at the switched off occasion.
Note! See chapter: Calibration for how to use Test Bolt to calibrate your system.
It is also possible to run a Spindle Functional Test or get the current Measurement values from the
transducers.
If you run a Spindle Functional Test the TC will run the same test that is done during the spindle
functional test in a diagnostic step. The results from the test are directly displayed in the Result frame.
With Measurement values the Result frame will continuously display the current measurement values for
torque and angle from all available tansducers on the spindle. It is possible to let this run while a cycle is
started from the PLC, meaning you can follow the torque and angle meauremetns during the tightening in
(almoste) real time.
Program mode
In Program mode you run the bolts by using one of the existing tightening programs.
