Attention!
Never apply line voltage to the digital input!
5.10 Relay outputs (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
“
11
”
and
“

”
are bridged (
Diagnostics / faults).
•
Fault indicated for: line fault, blown internal semiconductor fuse, broken controller-
internal voltage supply, overheating by the motor (thermostats

connected).
•
When switching off via enable (D1 = Digital In 1), the relay remains energized.
5.11 Potential at control voltage connections
The connections for the control voltage (< 30 V) relate to the common GND potential
(exception: relay contacts are potential-free). There is a potential isolation between the
connections for the control voltage and the PE conductor. It must be ensured that the
maximum external voltage at the connections for the control voltage cannot exceed 30 V
(between the
“
GND
”
and
“
PE
”
conductor terminals). A connection to the PE conductor
potential can be made if required;

”
terminal and the
“

”
connection (terminal for shield).
