5.7 Control output A1, A2, A3 (0 - 10 V) and PWM
The devices have three 0 - 10 V outputs andone PWM output (alternative use as a further 0...10 V
output).
It is not permissible to connect outputs of several devices to each other!
The following functions are pre-programmed at the factory (other functions can be assigned in
the IO Setup):
0 - 10 V Output:
•
Output 1 : terminals “ A1 ” / “ GND ” (I
max
10 mA). For ETAvent fans with 0 - 10 V signal or exhaust
air dampers in the compartment (IO Setup: A1 function = “ 0 ” → ventilation)
•
Output 2 : Terminals “ A2 ” / “ GND ” (I
max
10 mA). Regulator 2 e.g. for throttle shutter after the
exhaust air fan in the stall (IO Setup: A2 function = “ 2 ” → shutter) factory inverted(10 V...0 V)
i.e.: 10 V = shutter CLOSED, 0 V = shutter OPEN
•
Output 3 : Terminals “ A3 ” / “ GND ” (I
max
10 mA). For Heating (IO Setup: A3 function = “ 1 ” →
Heating )
PWM output alternatively 0 - 10 V
•
Output PWM : terminals PWM / +24V. For ETAvent fans with PWM input (IO Setup: PWM
function = “ 0 ” → ventilation)
•
To change to 0 - 10 V output plug internal jumper “ J1 ” at the top!
Information
Inverting outputs andsetting curve points possible (e.g. for not linear ouput) in IO Setup ( Installation
menu).
5.8 Voltage supply for external devices (+24V, GND)
There is an integratedpower supply for external devices, e.g. a sensor. Te24 V, output voltage
tol/- 20%. max. loadcurrent Technical data.
It is not permissible to connect outputs of several devices to each other!
In case of overloador short circuit (24 V – GND), the external power supply is shut down (multi-fuse).
The device performs a “ Reset ” andcontinues operation.
5.9 Relay outputs (K1, K2, K3)
The device has three relay outputs, the following functions are pre-programmed at the factory . Other
functions can be assignedin “ IO Setup ” . Max. contact load5A / 250 V AC.
K1: Fault indication
•
Connection of the  oating contacts to the terminals 11, 12, 14.
•
For operation the relay is energizedi.e. terminals “ 12 ” and “ 14 ” are bridged (factory setting not
inverted).
•
With power failure, internal fuse failure, temperature malfunction or fan error, the error message
relay at the corresponding control unit of the compartment drops, the terminals “ 12 ” and “ 11 ” are
bridged. The “ Master ” unit identi  es a malfunction of a network user via the data link, i. e., if a
network user displays a malfunction, the error relay in the master unit also drops. Due to this
function the fault relay of the “ Slave ” devices can be assigned if necessary different functions.
•
The fault message via the relay can be acknowledged with the “ ESC ” key. If the fault persists
(e.g. sensor break) a message is receivedagain after the adjustable time span “ Alarm Pause ”
(factory setting 60 minutes).
The error message is not to be layedin the same cable as the bus line.
K2: Heating
•
Connection of the  oating contacts to the terminals 21, 22, 24.
K3: Peak load fan
•
Factory setting relay “ K3 ” for function “ peak loadfan ” assigned( “ Installation ” - “ IO Setup ” ).
A secondfan can be switchedon via the terminals “ 31 ” und “ 32 ” .The activation must be made in
“ Installation ” - “ Ventilation ” (peak load).
Information
Inverting relay function in IO Setup( menu installation) possible.
