Siemens Sensformer®
(Option)
The Sensformer is used for digital transmission of the
measurement data in real time. By means of an app, an
overview of the status of the individual transformers be-
comes possible. Likewise, a push message can be sent in
the event of an error message.
The connection of the sensor transformer is located in the
box on the front side of the upper press frame or in the
control cabinet of the housing.
Information on connection and operation are in the app at
the Google Play Store available.

Fan (Option)
A control unit is required for temperature-dependent
switching on of the fans (AN/AF operating mode). Switch-
ing on and off is carried out via an adjustable time or tem-
perature in the monitoring unit.
Depending on the type, the fan is already connected to a
monitoring device or is intended for the connection to a
control device provided by the customer.
The connections of the fan are located on the fan motor of
the individual fan on the bottom side of the transformer.
•
Connect the fan according to the operating instruc-
tions of the fan.
•
During commissioning, check the function of all fans
•
Ensure that the fans are rotating in the correct direc-
tion
Notice:
On delivery, the default setting of the monitoring system
types T154 and NT935 includes a functional test for fans. If
run in the factory default setting, every 96 hours the fans
will undergo a short test lasting 5 –10 minutes.

Cooler (Option)
If a cooler is installed in the transformer housing (operat-
ing mode WF), connect the cooler to an external cooling
circuit before switching on the transformer. Take care of
the information on the coolant connection regarding
•
type of cooling agent
•
max. pressure
•
Flow rate
•
Max. Input temperature of the coolant
Open the shut-off valves of the cooler before switching on
the transformer.
Follow the operating instructions of the cooler.
Make sure that no power lines are resting on the surface of
the cooler.
