Pallet Wrapper fault
Pallet Wrapper Won't Start
A pallet wrapper that won't start is nearly always a power supply, safety circuit or control fault — common across all brands and ages of machine, and usually resolved in a single call-out once properly diagnosed.
Does this match your fault?
Common symptoms
✓
Screen is dead or completely blank on power-up
✓
Machine powers up but will not run a cycle
✓
Alarm showing that will not clear after reset
✓
Works intermittently then stops starting altogether
✓
Machine starts to home then stops mid-sequence
✓
No response from start button, display active
What causes this
Typical causes
Safety circuit open
E-stop engaged, guard interlock not made, or a door/gate sensor not reading correctly. The machine will not start until all safety inputs are satisfied.
No control power
Blown fuse, tripped isolator, failed PSU or a loose connection in the control panel. Common on older machines or after power surges.
Machine not homed
Many wrappers require the carriage or turntable to be in a known home position before accepting a start command. A failed home sensor prevents this.
Uncleared alarm state
A fault from a previous cycle has not been properly acknowledged. Some machines require a specific reset sequence, not just a button press.
Before calling an engineer
What to check first
These are the practical checks worth trying before calling out an engineer. If none of these resolve the fault, or if the issue keeps returning, it needs a proper diagnosis.
01
Check all E-stops are released and reset
Walk around the machine and confirm every emergency stop button is fully released by twisting it out. Some require a key. Press the main reset button after releasing all E-stops.
02
Check guards and safety gates are fully closed
Open and firmly close every guard panel and safety gate. Look for any that are not seating properly or have a damaged interlock switch. A gap of a few millimetres can prevent the safety circuit making.
03
Check the isolator and main power supply
Confirm the main isolator is fully in the on position. Check the supply fuses in the panel if accessible. If the display is dead, the issue is likely upstream of the control board.
04
Read the fault code on the display
If the display is active, note the exact fault code or message shown. Do not just reset — take a photo of the screen and include it when you report the fault. This speeds up diagnosis significantly.
When to call us
If any of these apply, call now
At this point, continued resets or workarounds are unlikely to resolve the underlying fault. A proper diagnosis is faster and cheaper than repeated call-outs for the same issue.
No control power at all — display dead, machine completely unresponsive
Safety fault that will not clear after all guards and E-stops have been checked
Fault is intermittent — machine starts sometimes but stops starting without warning
