Model A36R

3. Quick Start Guide

Encoder and cable installation instructions can be found in the quick start guide, located on the product page at encoder.com

3.1 Cabling Considerations

It is recommended that the encoder shaft and flex mount are secured prior to securing the cable. For header (RMH) units, mating
the cable prior to mechanical installation may result in connector damage.
The recommended minimum bend radius for Model A36R cables is 2.0 inches. For applications where the encoder cable is static,
tighter bend radii are acceptable.
Strain relief shall be no less than 2.0 inches from the encoder. For cables mating to header (RMH) units, apply strain relief to the
jackets portion of the cable. Do not apply strain relief to directly to wires and avoid tight bend radii for wires.

4. A36R Configuration Options

The Model A36R is available in any combination of the following configuration options:
Shaft/Bore
Blind Hollow Bore
Thru-Bore

4.1 Multi-Turn Options

The Model A36R is available in two different multi-turn options: XXN and XXL.
The XXN version operates as a fully functional Normal multi-turn encoder, but multi-turn count will be lost during power
interruptions to the encoder. This option is adequate if uninterruptible voltage can be supplied to the encoder at +VDC. See
product datasheet for voltage and current requirements.
The XXL version includes a Low power circuit for battery backup of multi-turn position data. A small external battery or power
source will maintain position data for many years, even in main power loss situations.

4.2 Low Power Circuit (XXL) Operation

Model A36R encoders with the XXL option use a low power circuit that continuously monitors the main voltage. If the main
voltage drops below the minimum threshold, it switches to backup voltage to maintain multi-turn position data.
The low power circuit also monitors battery voltage, featuring both error and warning thresholds. A battery warning indicates
that the battery should be replaced soon to avoid multi-turn data loss. A battery error is a latching condition that indicates battery
voltage has dropped below the usable threshold and multi-turn position data will be lost if main voltage is lost.
