Operating instructions

• Set point 2 (X5.2.11 - X5.1.13 ground) 0-5V default

The inputs set point 1, 2 are two electrically equal analogue inputs for current or voltage signals,

with subsequent A/D converter (resolution 0.025% of the ﬁnal value), and they may be set to the

following signal ranges:

0(4)-20 mA (Ri = ca. 250 V / max. 24mA) see ATTENTION

0-5 V (Ri = ca. 8,8 kV / max. 12V)

0-10 V (Ri = ca. 5 kV / max. 12V)

The following table shall be used for the hardware conﬁguration of the set point inputs (see also

FILE COMPONENT MOUNTING DIAGRAM CONTROL DEVICE, ﬁgure 10). If the hardware conﬁ-

guration is changed, the Thyro-P parameters must be changed accordingly with the LBA-2 or the

Thyro-Tool Family.

X221 for Set point input 1

JUMPER X221 Signal range Set point input 1

closed* 0(4) -20mA (X5.2.10)

open 0-5V / 0-10V (X5.2.10)

X222 for Set point input 2

JUMPER X222 Signal range Set point input 2

closed 0(4)-20mA (X5.2.11)

open* 0-5V / 0-10V (X5.2.11)

* default

ATTENTION

If the open-circuit voltage of the connected set point exceeds 12V in the 20mA signal range, the

set point inputs can be destroyed, if the belonging JUMPER (X221, X222) is open.

Within the stated input ranges, these values with the control characteristic may be adjusted to any

common signal characteristic.

For a set point poti (e.g. 5-10 k

) 5V supply voltage can be taken from terminal X5.2.5 (Ri = 220

short-circuit-proof).
