ACCEPTANCE CYCLE
Behavior: Battery amps falling, voltage at 14.4 V for 12 V systems, 28.8 for
24 V. (Voltage depends on battery type and ambient temperature settings.)
The Acceptance Cycle guarantees thorough charging by continuing to charge
the battery until the charging current becomes a small percentage of battery
capacity (2% default). The alternator output is varied to maintain the battery at
the acceptance voltage. During the Acceptance Cycle the alternator current limit
will not be exceeded even if a heavy load is placed on the system.
When the batteries have reached the acceptance voltage and the current is
below 2%, the Acceptance Hold Cycle begins. If the Acceptance Cycle has lasted
3.5 hours, the Float Cycle begins, even if the charged parameters have not been
met. If the voltage of either battery falls below the acceptance voltage for more
than two minutes, the Charge Cycle starts again.
HOW THE LINK 2000-R CHARGES
See page 18 of LINK 2000 manual for details of the Ideal Charge Curve.
The LINK 2000-R uses the Ideal Regulator Output Module to control the alternator
to conform to the Ideal Charge Curve’s four defining cycles; Charge, Acceptance, Float,
and Equalize. The following discusses details of each of the cycles.
NOTES: 1) Terminal references for the Ideal Regulator Output Module.
2) Voltage values given are for 70 °F and liquid lead-acid batteries.
TURNING THE REGULATOR ON
The regulator is turned on by supplying 12 V or 24 V to the REG ON (brown
wire) terminal.
It must have power only when the engine is running. See page 13.
DELAY START-UP
Behavior: No output on the Field terminal (blue wire).
Two-second delay allows time for the engine to start.
RAMPING UP
Behavior: Output of alternator increases over a 20-second period.
Ramping up the alternator output avoids shock-loading the belts with full
alternator output. The output on the FIELD terminal is increased over a 20-second
period until the alternator current limit (default value 100 A) is reached. The Charge
Cycle now begins. If the acceptance voltage is reached before the current limit,
the Acceptance Cycle begins.
CHARGE CYCLE
Behavior: Alternator current at maximum and battery voltage increasing.
The Charge Cycle ensures fast charging without alternator overload. The
alternator current limit will not be exceeded. The FIELD output is varied to hold
the alternator at its current limit until the acceptance voltage is reached. When the
acceptance voltage has been attained by either battery, the Acceptance Cycle begins.

Warning: Limitations On Use
Please refer to your product user manual for limitations on uses of the product. Specifically, please note that the Link 2000-R is not
intended for use in connection with life support systems and Xantrex makes no warranty or representation in connection with any use of
the product for such purposes.
Return Material Authorization Policy
Before returning a product directly to Xantrex you must obtain a Return Material Authorization (RMA) number and the correct factory
“Ship To” address. Products must also be shipped prepaid. Product shipments will be refused and returned at your expense if they are
unauthorized, returned without an RMA number clearly marked on the outside of the shipping box, if they are shipped collect, or if they are
shipped to the wrong location.
When you contact Xantrex to obtain service, please have your instruction manual ready for reference and be prepared to supply:
• The serial number of your product
• Information about the installation and use of the unit
• Information about the failure and/or reason for the return
• A copy of your dated proof of purchase
Return Procedure
1. Package the unit safely, preferably using the original box and packing materials. Please ensure that your product is shipped fully insured
in the original packaging or equivalent. This warranty will not apply where the product is damaged due to improper packaging.
2. Include the following:
• The RMA number supplied by Xantrex Technology Inc clearly marked on the outside of the box.
• A return address where the unit can be shipped. Post office boxes are not acceptable.
• A contact telephone number where you can be reached during work hours
• A brief description of the problem
3. Ship the unit prepaid to the address provided by your Xantrex customer service representative.
If you are returning a product from outside of the USA or Canada
In addition to the above, you MUST include return freight funds and are fully responsible for all documents, duties, tariffs, and deposits.
If you are returning a product to a Xantrex Authorized Service Center (ASC)
A Xantrex return material authorization (RMA) number is not required. However, you must contact the ASC prior to returning the product
or presenting the unit to verify any return procedures that may apply to that particular facility.
