Operating modes
Adding mode
In adding mode the programmed preset „P“ is reached by counting
up. The signal output (final contact) is triggered as soon as actual va-
lue and preset are identical. Any external, manual or automatic reset
will make the counter reset to zero or to a programmed offset value.
Subtracting mode
In subtracting mode the programmed preset „P“ is reached by coun-
ting down. The signal output (final contact) is triggered by zero or a
programmed offset value.
No matter what counting mode has been defined, the incoming
impulses may be added or subtracted. For more details please refer
to chapter 5.1 Counting modes.
In the case of two counting signals, phase offset by 90° and with
fourfold evaluation, the maximum counting frequency reduces to
5 kHz.
3.7 Executing the test routine
The test routine is described below.
Start test
➜
Press the keys
and
simultaneously and switch the
counter on.
●
All the display segments will be displayed automatically in se-
quence and are thereby tested for functional capability.
Test repeat
If you wish to repeat the test:
➔
Press the
key.
Test extension
Other counter functions can be tested:
➔
Press the
key again.
No machine functions may be connected when the outputs are
tested.
Testing of inputs A and B and reset input R.
●
Inputs can be triggered simultaneously or individually. A display
is only provided when a signal is applied.
Output test.
The output is now activated.
Reset the output with the key
.
Testing of DIP-switches in accordance with ON/OFF settings. The
settings and functions of the DIP-switches can be changed while
the test is in progress.
End of test
The test routine is now terminated.
