AROMAT PLC
The Sharp SX
TM
Bagger is controlled by an Aromat
FPΣ PLC. This is an NPN (sinking outputs) device
with 16 inputs and 16 outputs.
Check that there is power reaching the PLC by
checking for green lights on top of the PLC. If there
are no lights, check the PLC Power connector, or
troubleshoot the 24VDC Power Supply. If there is a
red blinking light on the PLC, the PLC has faulted,
contact Sharp Packaging.
There are no adjustments necessary on the Aromat
PLC
1. Remove the six screws holding the Frame
Cover. Set screws and Frame Cover aside
(Figure 3-73).
2. Remove all connections from the Aromat PLC.
There are six connections: Power, Display and
four ribbon cables. Note where the ribbon
cables are connected to the PLC (Figure 3-74).
3. Using a small flat screwdriver, pull the blue DIN
rail release tab toward you and pivot the PLC
up and back (Figure 3-75).
4. Remove old Aromat PLC and set aside.
5. Place new Aromat PLC onto DIN rail with the
circular plug closest to you.
6. Reconnect all wires (Figure 3-74).
