UWS-1RL

Overview

Pre-owned UWS-1RL units appear on the used equipment market and are typically described as used and in good working condition. Buyers should note that some sellers report they have not fully tested the machine.

Key Features

• Wrap, weigh and label in one unit — marketed as an auto wrapper, food packager, labeler, weigher with scales.
• Roll-film wrapping — categorized under roll-type wrapping equipment (Wrappers - Roll) on the used market.
• CPUI-based control — intake switches connect through a dedicated CPUI cable assembly; the manual lists ML-44173 among the covered models.
• Solenoid-driven wrapper — a dedicated solenoid board serves as the wrapper's DC power supply.
• Dedicated applier (label) control box — manual illustration PL-53140 covers ML-44173, with its own solenoid driver harness and fuse set.
• Scale integration — a scale motor controller harness appears in both the wrapper and applier control boxes.
• 240 VAC solid-state switching — fused SSR modules (0.5 A and 1 A) plus 280 V, 12 A solid-state relays.
• Fully documented parts catalog — Form 34203 Rev. A identifies boards, harnesses, fuses and fasteners by Hobart part number.

Parts & Documentation

Form 34203 Rev. A (April 2010) is the Hobart replacement-parts catalog for the Ultima Wrapping System family, and PartHubz supplies this manual along with replacement parts for the UWS-1RL. Because the manual identifies components by Hobart part number, ordering by number is the most reliable way to match parts — the same principle the aftermarket parts trade applies to this machine.

Operation

Per the parts manual, product presentation starts at the intake switches, which connect to the CPUI through a dedicated cable assembly (00-046941 lists ML-44173 among the covered models). Inside the wrapper control box, the CPUI harnesses (CPUI/Relay, CPUI Power/T1, Power/T2) distribute power and signals, the solenoid board — described in the manual as the wrapper DC power supply — powers the wrapping function, and fused 240 VAC solid-state relay modules handle the switching. Weighing ties in through the scale motor controller harness (00-042981-00001), which appears in both the wrapper and applier control boxes. Label application runs from the separate applier control box (illustration PL-53140), which carries its own solenoid driver harness and fuse set (F1 3 A, F2 0.5 A, F3/F4 7 A fast-blo, all 250 V).

Applications

Wrap-weigh-label stations like the UWS-1RL are the workhorse at supermarket service counters — meat, poultry, seafood, deli and produce — where trays are film-wrapped, weighed and labeled for sale. The roll-film format and integrated scale also suit fresh-food packaging at independent grocers, butcher shops and small processors.
