Initialising all memory locations with default values
Before starting, all memory locations with default values (e. g. set register lengths) have to be
initialised. Mains power−up initialises all memory locations with the value "0". Data on the memory
locations is not saved with mains failure protection (C0003).
The initialisation is effected in a slow task. The message to the higher−level control system is effected
via STORE3−BUSY and STORE3−RDY (handshake signals).
Procedure:
1. Apply a default value to the input STORE3−INIT−POS.
2. Via a LOW−HIGH edge at STORE3−INIT the value at STORE3−INIT−POS is written to all 16
memory locations.
– STORE3−BUSY is set to HIGH immediately.
– As long as STORE3−INIT = HIGH, all other functions remain inhibited.
3. After the initialisation,
– STORE3−BUSY is set to LOW,
– STORE3−RDY is set to HIGH.
4. Set STORE3−INIT = LOW.
– STORE3−RDY is set to LOW.

Note!
If different cutting lengths are lying between the point of cutting/register and the
mark recognition, no initialisation can be effected.
In this case you have to enter the default values directly in C1726/1 ... C1726/16.
