Continue Stroking or Stop and Notify
(EPC03)
Set this bit only if you your QDC module does NOT have control of all
valves required to change direction of ejector travel after each stroke.
- BIT 12 controls QDC module reaction when it completes any
advance or retract stroke during the ejector profile. The QDC
module:
0 = Runs the ejector profile without interruption
1 = At end of stroke:
* stops the ejector profile
* sets outputs
* notifies the PLC processor
Select this bit as follows, based on how you configured your ejector
hydraulic circuit.
Does the QDC module have control of all valves
required to change direction of ejector travel?
Then set
Bit 12 to
Then the QDC module; And Your Ladder Logic Must:
Yes 0 Initiates each subsequent retract/advance stroke
upon completion of the preceding one.
Toggle DYC02ĆB14 (B35/414) to
command the QDC module to
execute the entire ejector profile.
For example: Direction of ejector travel is determined by a biĆdirectional flow valve connected to the QDC module.
No
1 * Stops the ejector profile
* Sets outputs to endĆofĆprofile setĆoutput values
* Notifies the PLC processor
Control directional valves NOT
connected to the QDC module to
assist executing the ejector profile.
For example: Direction of ejector travel is determined by uniĆdirectional flow valves connected to outputs controlled by the PLC processor.
We provide the following partial list of the interactive command and
status bits to help you program a stop-and-notify ejector profile in
your PLC ladder logic (for use when EPC03-B12 = 1).

For additional ladder logic programming, refer to chapter 6.
Record a value for bit 12 accordingly on Worksheet 8-F.
