b. Troubleshooting and rewiring the power outage on the dry side.
c. Troubleshooting of the BSA panel.
d. Troubleshooting of the wrapper machine.
e. Troubleshooting for Cuber up/down mechanism.
2. Current Projects
a. Height adjustment for pavers on wet side.
b. Replacing limit switches on the conveyors on the block plant.
3. A.Rewiring of the Hydraulic valve wire connecters for the
Cuber Arm.
Cause of the Problem:
Wear and tear of the wire connector.
Delay in arm movements.
Possible cause of a loose contact.
Troubleshooting:
A new 120v connector was replaced with the old one.
The connector was rewired from the junction box.
New connectors were ordered for future use.
B. Troubleshooting and rewiring the power outage on the dry
side.
Cause of the Problem:
No power on the dry side conveyor.
Photocells inactive.
Complete loss of power till the cuber.
Troubleshooting:
Possibility of a cut wire during cleanup was troubleshot.
All loose/cut ends were reconnected using wire nuts.
Possible Fault at the BSA panel was troubleshot.
The wire was found and was traced to the junction box.
It was replaced with a new connection.
C.Troubleshooting of the BSA panel.
Cause of the Problem:
BSA panel showing various fault conditions at the wet side control panel.
BSA motor tripping.
Fault at different intervals.
4. Troubleshooting:
PLC program was used to find different error codes.
Based on various inputs and outputs various wires were rewired.
All loose joints were tightly connected.
BSA working fine without any possible fault message.
However a lot of wiring has to be labelled and tightened as they are not in proper condition.
D. Troubleshooting of the wrapper machine
Cause of the Problem:
Wrapper was not moving.
Error message at the wrapper panel.
Troubleshooting:
The Error code was traced out to be the Safe position photo eye.
It was readjusted to get the green light on top which determines that the switch is made.
The metal frame is still loose and could cause future misalignment. Thereby in needs to be fixed
or replaced.
E.Troubleshooting for Cuber up/down mechanism.
Cause of the Problem:
Cuber not going up and down.
Manual/ auto operation cannot perform.
Delay in dry side production.
Troubleshooting:
A loose wire was found which was replaced.
Eventually the fuse had also blown which was also replaced.
5. Current Projects:
A.Height adjustment for pavers on wet side.
Different manufactures for height measurement were contacted and are attached.
Informal quote was obtained.
Old sensors for accurate reading are still being tested.
Have to follow up with Mr. RED to inquire about height measurement system in arcadia.
B. Replacing limit switches on the conveyors on the block plant.
Conveyor 1 on the batching side of the Block plant is sometimes pouring more
materials.
The limit switch might be obsolete would need to be changed.
Have to follow up with Mr. Raghu to replace it during the next cleanup time.
