2. Electrical installation
This chapter contains information about the electrical installation,
commissioning of the absolute encoder
M36X1 / M3661R / M5861 analog.
2.1 Electrical installation
Switch off the plant!
Make sure that the whole plant remains switched off
during the whole electrical installation.
Electrical installation requires connectors or connection cables
(see Sendix absolute M36X1 / M3661R / M5861 data sheet).

4. Standard function
As a standard, the corresponding desired output signal ( 4 … 20m A / 0 … 10 V /0 … 5 V) is linearily factory-scaled over 16 revo-
lutions and supplied in the CW or CCW direction of rotation according to customer requirement.
The reference point is indicated by the LED from 0 … 1°.

4.1 Scaling function (optional)
The encoder is factory-set to a measuring range of 16 revolutions over which the corresponding output signal is scaled linearily.
Two scaling inputs (set 1, set 2 - see chapter Terminal assignment) allow the user to define himself a desired measuring range.
The desired measuring range must be > 22.5° and shall not exceed 65536 revolutions.
The factory-set output range of 4 … 20mA / 0…10V / 0…5V is scaled linearily over the desired measuring range.
To trigger the scaling operation, the corresponding scaling input must be connected with the supply voltage + V for at least
1 second.
Scaling process:
1. Turn the shaft to the desired start position.
2. Connect scaling input 1 with + V for at least 1 second.
3. Green LED flashes 1x.
4. Turn the shaft to the desired end position.
5. Connect scaling input 2 with + V for at least 1 second.
6. Green LED flashes 3x. The new measuring range is active.
(The output signal assumes the highest state)
Scaling input 1* Scaling input 2* Function
0 0 Normal operating mode
1 0 Setting the start position
0 1 Setting the end position
1 1 Resetting to the default measuring
range
* 0-GND, 1-mind. 1 sec. + V

4.2 Reference point display
With the factory-set „default“ scaling, the LED displays the reference point of 0..1°. The reference point display is no longer
available if another measuring range is scaled using the scaling inputs.
The scaling function is limited to 10,000 cycles. Beyond this limit, the error-free scaling of the output signal cannot
be guaranteed any more.
Actuate the scaling inputs only once the shaft has stopped.. Only this way will it be possible to take over the desired
start and end position of the desired signal scaling.
4.3 Resetting the scaled output signal
1. Connect scaling inputs 1+2 with + V for at least 1 second.
2. The LED sequence green / red / green is displayed. The factory-set scaling of the output signal is available again and is set to
the central value of the measuring range at the current position.
4.4 Scaling with direction of rotation change
Fixed output levels are assigned to the scaling inputs.
Scaling input 1 = lowest output level (current variant = 4 mA / voltage variant = 0 V)
Scaling input 2 = highest output level (current variant = 20 mA / voltage variant = 5 or 10 V)
If scaling input 2 is actuated first, followed by input 1, the new measuring range is defined with the reversed direction of rotation.
Inputs sequence Absolute position Sign of the curve
1 – 2 1 > 2 (CCW) Positive
1 – 2 2 > 1 (CW) Positive
2 – 1 1 > 2 (CW) Negative
2 – 1 2 > 1 (CCW) Negative

4.5 Limit switch function (optional)
With the limit switch function, the output signal does not remain at the last final value, but it makes a defined jump. This signal
jump can be used by a control as a limit switch. The output levels of the limit switches are factory-set.
