It is not permissible to connect outputs of several devices to each other!
The function of the signal output A1 (Analog Out 1) can be determined by

For motor fault the output signal remains for a slave controller (

combina-
tion).
5.9
Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e.g. a sensor (max. current load see technical
data).
In case of overload or short circuit (24 V
–
GND), the external power supply is shut down (multi-fuse).
The device performs a
“
Reset
”
and continues operation.

It is not permissible to connect voltage outputs in the device to each other!

Digital inputs (D1, D2)
Activation via

Attention!
No disconnection (isolation) when turned off, in accordance with VBG4
§
6)!
Never apply line voltage to the digital input!
It is not permissible to connect inputs of several devices to each other!

, the digital input
“
D2
”
can used for reverse of control
function.
For the effect of the regulation there are two functions:
•
“
Val > Set = n+
”
increasing modulation for increasing actual value over setpoint.
•
“
Val < Set = n+
”
increasing modulation for decreasing actual value below setpoint.
When terminals

”
bridged, the device works with the opposite function than the one set with
DIP 4!
