timing channels that are used so that die protection can be performed.
2) Recall a setup which was previously stored containing the proper PLS and die
protection data for this die.
3) If die protection is not required for this application, the operator may bypass
the die protection function (see Section 2.8.2). Then Error 243 may be cleared by
pressing the CLEAR key.
244 TO USE AUTO SS, MUST PROGRAM DIE-PROT INPUT TO MODE OTHER
THAN STATIC
When using the Automatic Single Stroke function of the System 2500, at least one
of the eight Die Protection inputs must be programmed to some mode other than
Static Mode. This is required so that at least one input will be forced to cycle with
each machine stroke to verify that die protection is being provided (i.e. to avoid
the situation where die protection is turned ON but no inputs are programmed to
be active).
Before this error can be cleared one of the following steps must be taken:
1) Reprogram at least one die protection input to a mode other than Static Mode.
2) Disable the Auto Single Stroke function (see Section 2.8.4.4).
245 DIE-PROT INPUT USES A TIMING CHANNEL THAT IS NOT
PROGRAMMED
Most die protection input modes require that a timing channel (17-24) be chosen
to provide a timing window for checking the required action. After the timing
channel has been selected, the timing channel MUST be programmed with on and
off setpoints to set the limits of the timing window. If this is not done, the die
protection function will not take place since no window will occur. The System
2500 generates this error to prevent machine operation if a timing channel has
been selected that does not have its setpoints programmed. To correct the error
the operator must go to the TIMING CHANNELS selection of the Die-Prot Menu
and program on/off setpoints for each timing channel that is used by a die
protection input.
