6.1. Operation as single channel counter (without direction signal)
or as positional counter (with direction signal)

Settings: Make sure that the DIL switches are set according to the encoder in use, and
that position 6 of switch DIL1 is OFF (Teach function active).

Self test: Upon power up, both front LED’s must be lit first, and the yellow status LED
must switch off after the self-test has been concluded successfully (approx.1 sec.).

Scaling of the analogue output with use of the Teach function:
Press the Teach button one time. The status LED will blink in a slow sequence now
while the unit waits for setting of the minimum counter state, this is the state where
later you expect the analogue output to be zero (in general, this will be with counter=0).
Please set the counter to the desired state or move the encoder to the desired position
and reset the counter to zero. Then press the Teach button again. This stores your
minimum counter definition.
The LED will blink in a fast sequence now and the unit waits for setting of the maximum
counter state, this is the state where later you expect full scale analogue output.
Please get the counter to the desired state or move your encoder to the desired position.
Then press the teach button once more. This stores your maximum counter definition
and the LED will switch off.
After this Teach procedure, your analogue output is set to 0–10 volts swing between the
minimum and the maximum counter state.
6.2. Operation as a summing or differential counter with
two independent impulse inputs (A+B, A-B)
In principle, the Teach procedure is exactly the same as shown under 6.1, but the minimum and
maximum counter states already refer to the sum or the difference of the count on both inputs.
