Commissioning
The commissioning of the LOCON is to be carried out in the following order:
1)
Connecting the encoder
2)
Connecting the external program selection, if it is required
3)
Connecting the CLEAR-signal if using an incremental encoder
4)
Connecting the used outputs
5)
Connecting the serial interfaces, if required
6)
Connecting the 24V supply voltage
The LOCON now conducts the self-test that is described in the following chapter. After this self-
test the device is operational, i.e. the program that was active (when it was switched off the last
time) is carried out.
At the commissioning the result of the self-test, the hardware configuration and the software revi-
sion as well are output to an additionally connected PC.
In case any error messages appeared, which LOCON is able to detected independently, the LED
“Error“ flashes and a corresponding error message is presented. The meaning of this number
and the required actions are described in the chapter "Error messages".
If a terminal is connected at the time the error appears, the error message is also presented in
plain text there.
9.1
Self-test
After the LOCON is switched on it performs a self-test. This test takes a few seconds. Afterwards
the device is ready for operation.
The following tests are conducted during the self-test:
•
Test of the entire RAM area for defective memory addresses
•
Checksum test of the EPROM
•
Checksum test and validity test of the EEROM
•
Validity test of the cam program
Should errors occur during the self-test, these are presented on the display if possible (see chap-
ter "Error messages").
