3Intended useThe EBB 4000 provides a simple battery
power supply for absolute rotary encoders
with a battery-buffered revolution counter.
For this purpose, the EBB is interposed in
the connection between the encoder andthe subsequent electronics. At present,
the EBB can be used for operation of thefollowing rotary encoders with theEnDat22 interface:• EBI 1135
• EBI 1335
• EBI 135
• EBI 4010
Battery-buffered encoders require abattery power supply to ensure continued
functioning of the revolution counter (andthus detection of the multiturn position)
upon failure of the regular operatingvoltage UP.
For this purpose, the EBB can be loadedwith up to two batteries of the typexR14250 (½ AA). Operation is possible
with either one or two batteries.
Battery life and replacement
The service life of the loaded batteries
depends on the battery type, the operating
conditions, and the encoder. For relevant
information regarding the encoder, pleaserefer to the product-specific documentation.
The battery must meet the following
minimum characteristics:
TypexR14250 (½ AA)

Voltage

3.6 V to 5.25 V

Reverse current
tolerance≥ 8 mA

RequiredcertificationUL 1642

The longest operating times are achieved
through the use of Li-SOCI2 batteries(lithium thionylchloride). Please be awarethat the temperature range of the EBB may
be limited by the type of battery used.

4When used improperly, lithium batteries
can be hazardous. The EBB therefore
contains appropriate protective circuitsthat protect the battery from the followingfaults:• Inverse polarity due to incorrect insertion
into the battery holder• A short circuit between UBAT and 0VBAT
on the encoder connector or EBB cable• Excessive reverse current to thebatteries due to leakage currents fromthe encoder
If batteries with a total capacitance of1200 mAh are used, then the typicalservice life is nine years (EBI 1135/135)
or six years (EBI 1335/4010) under typicaloperating conditions; namely, two 10-hour
shifts under normal operation, four hours inbattery-buffered mode, a battery
temperature of 25 °C, and typical selfdischarge.
The encoder contains an integrated
monitoring circuit for the battery. If
the battery voltage falls below certain
thresholds, then the encoder issues thefollowing warnings or error messages,
which are transmitted over the EnDatinterface:• Warning: “Battery charge”≤ 2.8 V ±0.2 V in normal mode
• Error message: “M Power interruption”≤ 2.2 V ±0.2 V in battery-buffered mode(transmission to subsequent electronics
only after switching to normal mode)
The failure indicated by the error message“M Power interruption” results in the lossof the multiturn position, requiring theencoder to be re-homed in the application(the singleturn position is not affected). Thiscan be avoided through a timely batterychange. HEIDENHAIN recommends thatthe battery be exchanged with the encoder
under power (UP) because this eliminates
the risk of losing the multiturn position.
When the encoder is under power,
neighboring components may beelectrically charged. Relevant informationmust be obtained from the machine
manufacturer. Alternatively, if two batteries
are used, then they should be replaced
separately, one after the other.

Functional safety
The EBB constitutes a passive component
and thus does not affect operation in safetyrelated applications. Any characteristics
related to functional safety are determinedsolely by the connected encoder and thesubsequent electronics (contact themanufacturer where applicable).
Mounting accessories
ScrewsFor fastening the EBB
ISO 4762 – M4 x 16 – A2-70(two for every EBB)ID 200507-12
Spacer bolts
For thermally insulated installation
M4 x 10 (steel: X12CrNiS18-8)(two for every EBB)ID 204476-20
Notes• HEIDENHAIN recommends that each
encoder be operated with a separate
EBB.
• During or immediately after connectionof the battery, the main power supply UP
must be applied to the encoder so thatthe encoder will fully initialize after having
been in a completely de-energized state.
Otherwise, the encoder will consume asignificantly higher amount of battery
current until main power is first supplied.
• The loading and changing of batteries
must be performed by qualified
personnel!
• Even during normal operation of thebattery-buffered encoder (i.e., undermain power UP), a small amount ofbattery current continues to flow. The
amount of this current depends on theoperating temperature and is stated in
the respective product documentation.
• For proper control of the battery-bufferedencoder, EnDat Specification 297403 andthe EnDat Application Notes 722024(Chapter 13, on battery-bufferedencoders) must be adhered to.
• Batteries are not included in delivery.
