7. Controlling Conveying Systems
The mAI085-MB Actuator Interface allows the direct control of simple conveying systems. The
interface has several timers that facilitate this control. These timers in conjunction with the
discrete output system control the conveying system. The following timers are used:
ID Description Menu
oPL
Provides a pulsed output from Output 1 to start a conveying system. If this
value is set to 0, Output 1 will remain on continuously whenever the OPEN
lamp is on. If a value is set in this timer the output will pulse on for the time
selected in seconds each time the OPEN lamp turns on.
LoC
cPL
Provides a pulsed output from Output 2 to stop a conveying system. If this
value is set to 0, Output 2 will remain on continuously whenever the CLOSE
lamp is on. If a value is set in this timer the output will pulse on for the time
selected in seconds each time the CLOSE lamp turns on. The operation of
the output will be delayed if a value is entered into the cdL timer.
LoC
odL
Delays the opening of the actuators to allow the conveying system to fully
start. Output 1 will energize (or pulse if oPL is set) immediately upon the
OPEN lamp illuminating. The actuators will begin to open after this delay in
seconds. This timer starts immediately upon entering Open mode.
LoC
cdL
Delays the stopping of the conveying system until all of the gates are closed
and the system has been purged. This timer starts after the CLOSE lamp
illuminates and all of the gates have been issued close commands. Once
this timer expires, Output 2 will energize (or pulse if cPL is set).
LoC
odL
This timer allows for the different location of each actuator along a conveying
system. Actuators near the start of the conveying system must open first,
with each successive actuator opening a short time latter. This ensures an
accurate blend of the material. Each actuator has a timer that delays the
opening after the primary delay odL has expired.
CtL
cdL
This timer allows for the different location of each actuator along a conveying
system. Actuators near the start of the conveying system must close first,
with each successive actuator closing a short time latter. This ensures an
accurate blend of the material. Each actuator has a timer that delays the
closing when the interface enters Close mode.
