Tanco AutoWrap Winder Control Unit

Typical Faults:
The control unit does not work
The buttons do not work
The winding function is not operational
The front glass has cracks

The control unit CR9002 belongs to the Tanco CR900/x family of controllers for AutoWrap bale wrappers. It is an in-cab electronic control that manages and monitors the wrapping cycle (automatic and manual), interfacing with the electro-hydraulic distributor and machine sensors (table rotation counting, “tip”/tilt, cut & start, possible autoload). It is typical on Tanco rotary models of the 13xx/14xx/15xx and 5xx series, in CR900-* variants, with dedicated logic and keypad.

Technical features

• Power supply: 12 V DC with direct connection to the tractor battery (dedicated positive/negative).
• Operator interface: keypad and 7-segment/alphanumeric display for status, rotation count and mode indications.
• Operating modes: Automatic (full programmed cycle) and Manual (individual controls).
• Quick functions: cycle start/stop, ADD WRAP (add turns), table rotation R/L, tip up/down, film cut & start management.
• Programming: set number of table rotations (target 0–99, depending on model), batch counter and bale totalizer.
• I/O to machine: outputs to hydraulic solenoid valves; inputs from rotation/proximity sensor on the table, limit switch sensors tip/cut & start, possible autoload sensors.
• Protections: alert messages on the display, emergency/stop on prepared versions; wiring with sealed connectors (Deutsch or equivalent).
• Compatibility: various AutoWrap rotary models (e.g. 1300/1310/1320, 1400, 1510/1514, 580/1080… depending on the CR900-* version).

DIPA can intervene to overhaul these modules thanks to its experience and expertise.

Functions

• Automatic cycle management: rotation counting, film cut and resume, table positioning for discharge, return to loading position.
• Manual control: actuation of individual phases for diagnostics and handling of specific field situations.
• Quick adjustments: change number of wraps, add wraps on the fly (Add Wrap).
• Operational diagnostics: display indications for status, errors, suggested interventions; support for test procedures.
• Safety and efficiency: function interlocks to reduce operator errors; cycle time optimization with preprogrammed sequences.
• Counting: partial batch counts and totalizer for work statistics.

Applicable models

• Tanco AutoWrap rotary wrappers of various generations (series 13xx/14xx/15xx; some 5xx), equipped with CR900 series controllers.

Typical faults

• The control unit does not work
• The buttons do not work
• The wrapping function is not operational
• The front glass is cracked

Final conclusions

The CR9002 is a robust and widespread controller used on Tanco AutoWrap wrappers, designed to automate the wrapping cycle and simplify field use. Recurring issues concern power supply, user controls and power stages to the valves.
