Operating manual TROX TNC-EASYCONTROL
Connecting mechanical dampers and capturing
their end positions
Signals from mechanical dampers can be received at the
inputs of TNC-EASYCONTROL.
It is not possible to combine mechanical dampers and
dampers with an electrical actuator.
Set selector switch S2 to C (see arrow).
The wires for the fire damper position signals are connected
to the plugs.
Contacts 3 (FD1) and 4 (FD2) are the inputs for the position
signals.
Note: Counting is from the right to the left.
24 V DC must be supplied to the inputs of TNC-
EASYCONTROL, hence the limit switches must also be
supplied with a 24 V DC operating voltage. This voltage is
supplied by the plug on terminal 2.
Plug assignment
All non-used inputs of the plug must have a wire link.
A 'duct smoke detector' switch can be used to connect
an RM-O-3-D.
The duct smoke detector does not affect the fire dampers;
rather, it detects smoke or contamination and signals it to the
display or to the central BMS.
