Attention!
•
For a high interference immunity a capacitor must be connected directly to the sensor (1nF parallel).
With ZIEHL-ABEGG temperature sensors type TF.. (KTY81-210) a capacitor is integrated.
•
Never apply line voltage to analog inputs!
5.8
Control output 0 - 10 V (A1, A2, A3)
The device has three 0 - 10 V outputs:
Output
Terminals
Factory-programmed function
Installation menu -> IO Setup
output 1
A1 / GND
A1 Function:
|
0
|
=
Ventilation
A1 Invert: OFF
e.g. for exhaust air vent in cot for central exhaust air systems
output 2
A2 / GND
A2 Function:
|
2
|
=
Shutter
A2 Invert: ON
e.g. for throttle shutter behind the extractor fan in cot inverted as factory
setting (10 V to 0 V) i.e.: 10 V = shutter CLOSED, 0 V = shutter OPEN.
output 3
A3 / GND
A3 function:
|
1
|
=
Heating
A3 Invert: OFF
e.g. for Heating

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.

Relay outputs (K1, K2, K3)
The device has three relay outputs:
Output
Terminals
Factory-programmed function
Installation menu -> IO Setup
K 1
11, 14, 12
K1 Function
:
|
3
|
=
Fault
K1 Invert: OFF
•
For operation the relay is energized i.e. terminals
“
11
”
and
“
14
”
are
bridged (factory setting not inverted).
•
In the event of a power failure, failure of the internal voltage supply, or a
temperature or fan fault, the alarm relay at the relevant cot controller
drops out and terminals
“
11
”
and
“
12
”
are bridged. The
“
master
”
device
identi
fi
es a fault on a member via the data connection; i.e. if a member
has a fault, the fault relay in the master device also drops out. Based on
this function, the fault relay of the
“
slave
”
devices can be allocated
different functions if necessary.
•
The fault message via the relay can be acknowledged with the
“
ESC
”
k-
ault persists (e.g. sensor break) a message is received again
after the adjustable time span
“
Alarm Pause
”
(factory setting 60
minutes).
The error message is not to be layed in the same cable as the bus line.
