Relay outputs (K1, K2)
The controller has two relay outputs (contact rating see technical data):
•
For Fault indication Relays K1
–
Connection of the
fl
oating contacts to the terminals 11, 12, 14.
–
For operation the relay is energized i.e. terminals
“
11
”
and
“
14
”
are bridged (factory setting not
inverted).
–
In case of power failure, motor fault (
“
TB
”
interruption), external fault (D1), temperature fault, the
fault signal relay drops out, the terminals
“
11
”
and
“
12
”
are bridged.
–
The fault signal over the relay can be acknowledged with the
|
ESC
|
-key combination. In such a
way the error remains existing (e.g. sensor fault) comes after an adjustable time interval again a
message (factory setting alarm pause 60 min (see Alarm).
•
For Heating Relays K2
–
Connection of the
fl
oating contacts to the terminals 21, 22, 24.
–
For heating
“
ON
”
relay energized i.e. terminals
“
21
”
,
“
24
”
bridged (factory setting not inverted).
Information
Inverting relay function in IO Setup possible.

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 con-
nections 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;
fi
t a bridge between
the
“
GND
”
terminal and the
“
PE
”
connection (terminal for shield).
