4. Controls

1 + In • 2 - In

The controls 1 and 2 are the attenuators for the

voltages fed to the sockets ! resp. ".

3 Offs.

This control adds a manually adjustable Offset vol-

tage, i.e. a fixed value is added to the internally calcu-

lated voltage difference a

• In

- a

• In

. The adjustable

offset range is approximately -10 V (fully counterclock-

wise) to +10 V (fully clockwise). In the middle position

the offset is approximately 0 V.

If only one of the inputs is used the module works as

an offset generator (and attenuator); the attenuated

and - if input " is used - inverted voltage with offset is

available at the Analog Sum socket § (see fig. 2 and

chapter 6).

4 Gap

This control is used to adjust the hysteresis (see

chapter 3 for details).

5 Comp. Function

LED 5 lights up if the internal voltage U

is positive

(> 0V) and consequently the Gate output is "high" (~

+10V).
