Masterplat Pallet Wrapper FAQs

What is the Masterplat used for?
A semi-automatic turntable stretch wrapper for stabilising pallet loads with stretch film (operator loads/starts cycle; machine wraps).
What is a Masterplat with PGS?
PGS is a power pre-stretch carriage designed to reduce film consumption (often up to ~250% pre-stretch depending on configuration) while maintaining excellent load containment.
What is “LP” (Low Profile)?
LP models have an ultra-thin turntable (e.g., ~30 mm) designed for easier loading with pallet trucks and reduced forklift impacts.
What is the “Freezer” version?
A configuration intended to operate reliably at very low temperatures (cold-chain / frozen environments).
How many pallets per day is Masterplat suited for?
Common positioning is medium to higher throughput sites; PGS is often recommended when you’re doing roughly 20–30+ pallets/day and want film savings.

What pallet weight can it wrap?
Depends on exact model/options; many Masterplat variants are marketed around heavy-duty capacities (often up to ~2000 kg)—verify your exact plate/spec.
What’s the standard wrapping height?
Varies by mast; common listings reference ~2200 mm wrapping height (with taller mast options available on some configurations).
Can it wrap unstable/light loads?
Yes—features like soft start and adjustable turntable/carriage speeds are designed to help with unstable pallets.
Can it do top sheets / covers?
Some installations add options/accessories; check your quote/configuration (not all Masterplat setups include top-sheet units by default). (Manuals/options list varies by model.)
Does the turntable stop in the same position each time?
Many versions list index-controlled turntable (repeatable stop position), helpful for forklift approach and workflow.

What does “pre-stretch” mean and why does it matter?
Pre-stretch carriages stretch the film before it hits the load, so you use less plastic while maintaining containment force (better cost + sustainability).
What is “PGS 250%”?
A common PGS configuration is around 250% pre-stretch, often achieved with geared setups (exact mechanism depends on model/version).
How do I control film tension/containment force?
Typically via the control panel settings. Many machines support easy/advanced modes and program-based adjustments.
Does pre-stretch film have to be “special”?
PGS machines are designed to work with power pre-stretch film; match the film type/spec to the carriage and your load needs.
Can I reduce film usage without losing stability?
Usually yes—by tuning bottom/top wraps, overlap, film tension, carriage speed, and pre-stretch (PGS helps most).

Is it hard to use for new operators?
Generally designed to be operator-friendly with stored programs and guided settings; training still matters for safety and repeatability.
Does Masterplat have different wrap “recipes”?
Yes—many setups allow multiple programs and parameter management (wrap counts, speeds, reinforcement zones, etc.).
How does it know pallet height?
Commonly via photoelectric sensors/photocells that detect load height during the cycle.
Can I set different top and bottom wraps?
Yes—top/bottom wrap selection is a standard feature in many configurations.
Can it wrap without going over the top (no roping/top passes)?
Yes—programs can be set to stop below the top if required for open-top loads (depending on sensor settings/program).

Do I need to bolt it to the floor?
Depends on model/site risk assessment and local regs; many turntable wrappers can be placed without bolting, but ramps/guards/accessories may change requirements. Consult the installation section of your manual.
How much space do I need?
You need clearance for turntable diameter, mast height, and forklift/pallet truck access. Dimensions vary—confirm against your exact model spec sheet/manual.
Can I load with a pallet truck instead of a forklift?
Yes—especially with LP versions and/or ramps designed for pallet truck access.

What are the main operator safety risks?
Pinch/crush points at the turntable, moving carriage/mast area, and entanglement with film—follow the manual’s safe-use and guarding guidance.
Should operators step onto the turntable?
No—this is generally unsafe and typically prohibited by manufacturer safety guidance. Use proper loading methods and keep clear during cycles.

What routine maintenance does a Masterplat need?
Regular checks/cleaning, inspection of rollers, sensors, carriage parts, belts/chains (as applicable), and safety devices—follow the maintenance schedule in the manual.
How often should I service it?
Follow the manufacturer schedule; many sites do daily/weekly checks plus periodic technical servicing depending on usage.
Where can I get the correct manual for my exact machine?
Robopac hosts Masterplat/Masterplat Plus manuals and repositories (ensure you match model + serial/version).

The machine won’t start a cycle—what should I check first?
Common basics: E-stop engaged, guards/safety circuit, power isolator, and whether the machine is in fault state requiring reset (manual has step-by-step).
What does error code E60 mean?
Often listed as film breakage (film torn / out of film / film path issue). Re-thread film and check film tension/rollers.
What does error code E61 mean?
Often listed as turntable movement blocked (obstruction or mechanical issue). Remove obstruction, verify turntable rotates freely, then reset.
What does error code E30 mean?
Often listed as an inverter fault (drive/motor/inverter issue). This commonly requires technical support after basic checks.
What does error code E83 mean?
Often listed as a communication error (electrical/electronic comms issue). Usually escalated to service.
The load is loose even with lots of wraps—why?
Usually settings: insufficient containment force/tension, too little overlap, wrong film type, or pre-stretch/tension not matched to the load. Adjust recipe and confirm film spec.
The film keeps snapping—what causes that?
Common causes: excessive tension, sharp load edges, poor threading, damaged rollers, or unsuitable film for the pre-stretch/tension settings.
