In the example Die Protection Screen shown in Figure 2.1, the information shown is for Channel 01
and includes Type of Stop Output, Window ON, and Window OFF, Number of Stroke Delay, and
a bar graph showing the timing window.
Section 2.10.1 Changing Channel Information
To edit die protection channel information, the user must first obtain access control. Access control
is described in Section 2.3. If the user obtains access control by using the password system, the user
must be configured to have access to change die protection settings. To begin the change setting
process, first position the cursor to the channel that is to be changed. If operating in a keyed access
mode, place the Program/Run switch in the PROG position. This step is not required if operating
in a password access mode. Then press the CHANGE SETTINGS softkey. If operating in a
password mode, access control must be obtained as described in Section 2.3. The cursor will move
to the View Channel information that is at the bottom of the screen.
Once all changes have been made, press the END CHANGE softkey to return the cursor to the die
protection inputs.
Section 2.10.2 Programming Stop Output
The Die Protection Module is capable of issuing a Cycle Stop (immediate stop) or a Top Stop to the
press if any die protection input does not respond as desired. The type of stop to be used for a
particular input must be determined by the operator according to the application. Some applications,
such as insuring that material is in position, require an immediate stop if a failure occurs. Other
applications such as monitoring the end of stock might require only that the press stop on top.
To change the stop type, gain access to the Channel Information Area (see Section 2.10.1), position
the cursor over the current stop type and press the CHANGE SETTINGS softkey.
Section 2.10.3 Programming Delay Time
When an input is programmed as a Static type, the Channel Information Area will be "Delay Time".
This feature allows the operator some flexibility in handling static inputs which have nuisance trips
due to momentary bouncing of the sensor. When the Delay Time is programmed with some value
other than zero, then the delay timer will begin to count down if the input changes to the improper
state (i.e., an "open" on an input programmed as normally closed.) If the input returns to the proper
state before the programmed delay times out, the timer is reset and no fault occurs. If the delay time
expires before the input returns to the proper state, a fault is generated. In this way, a momentary
change on the input can be ignored but a long term change on the input will cause a fault.
The range of values for the delay time is 0 seconds to 65.500 seconds in 0.001 second increments.
If the delay time is programmed as zero, a fault will occur immediately whenever the input goes to
the improper state.
