. Digital input can used instead for
enable, alternative for reverse of control function (DIP 8 =

).
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!

Relay output (K1)
An external fault indicator is available over the potential-free contacts of the built-in relay (max. contact
rating
Technical data and connection diagram).
For operation the relay is energized, terminals
“
12
”
and
“
14
”
are bridged. For fault the relay is de-
energized, terminals
“

”
and

are bridged (

Fault indicated for: line fault, blown internal semiconductor fuse, broken controller-internal

•
When switching off via enable (D1 = Digital In 1), the relay remains energized.
5.11
Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50V (between
“
GND
”
terminals and
“
PE
”
protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between
“
GND
”
terminal
and the
“
PE
”
connection (terminal for screening).
