study the wiring and connection diagram before working with the product. For
personal and equipment safety, and for optimum product performance, make sure you
entirely understand the contents before installing, using, or maintaining this product.

For safety and licensing (CE) reasons, unauthorise d conversion and/ or modificat ions
of the product are inadmissible.

e product should not be exposed to abnormal conditions, such as: extreme
temperatures, direct sunlight or vibrations. Long-term exposure to chemical
vapours in high concentration can affect the product performance. Make sure the
work environment is as dry as possible; avoid condensation.

All installations shall comply with local health and safety regulations and local
electrical standards and approved codes. is product can only be installed by an
engineer or a technician who has expert knowledge of the product and safety
precautions.

Avoid contacts with energised electrical parts; always treat the product as if it is
live. Always disconnect the power supply before connecting, servicing or repairing
the product.

Always verify that you apply appropriate power supply to the product and use
appropriate wire size and charac teristics. Make sure that all the screws and nuts
are well tightened and fuses (if any) are fitted well.

Recycling of equipment and packaging should be taken into consideration and these
should be disposed of in accordance with local and national legislation/regulations.

PRODUCT DESCRIPTION

e GTE fan speed controller automatically regulates the speed of single phase
voltage controllable motors (230 VAC / 50—60 Hz) according to the measured
temperature values. e maximum speed can be adjusted via an internal
trimmer. e minimum speed and temperature setpoint can be adjusted via
external potentiometers. ere are two product versions: -DM with Modbus RTU
communication and -DT with an integrated motor socket, power cable and a PT500
temperature probe. e fan speed will increase as the measured temperature
exceeds the setpoint temperature.

MOUNTING INSTRUCTIONS IN STEPS

Before you start mounting the GTE controller, read carefully “Safety and
Precautions”. Choose a flat surface for installation (e.g. a wall, panel, etc.) and

follow these steps:

1. Insert the supply and sensor cables through the cable glands and do the wiring

according to the information in section “Wiring and connections” while adhering
to Fig. 1 below.

Only for -DM version

NOTE

For the -DT version the power supply and the temperature sensor (PT500) are
included in the set and factory connected. Also, the -DT version has a Schuko
socket to plug in the motor / fan. If your unit is -DT, please skip step 1.

2. Fix the jumpers accordingly - see Fig. 2 Jumper positions below.

NOTE

e -DM version can be used both as a stand-alone unit or in conjunction with
a computer and operated by Sentera’s 3SModbus software or the Sensistant
configurator. When used stand-alone, its jumpers need to be set to the desired
values. When used in Modbus mode, its parameters are set via Modbus RTU,
so the jumpers can remain in their factory set positions. Refer to the Modbus

Holding Registers Ta ble below for the relevant settings.

range 170—230 VAC. e factory setting is 230 VAC.

5. Optional setting:

■

e Network Bus Terminator (NBT ) (see Fig. 5 NBT j um pe r) used with Modbus
RTU. By default the NBT is disconnected.

NOTE

Connect the NBT only in the two most distant units on the network line!

■

Connect the NBT by placing the jumper onto the pins as indicated above only
if your unit starts or terminates the network. Skip this step if your unit is not
the first or last on the network. See the examples below for more information.

VERIFICATION OF INSTALLATION INSTRUCTIONS

ATTENTION

Mind that the cables are live. Take the relevant safety measures.

1. Plug in the supply cable.

2. Switch on the controller via the illuminated ON/OFF switch.

3. Position the TEMP. potentiometer to max. position (35 °C). (See Fig. 9 -DM

version and Fig. 10 -DT version)

4. e connected motor will run at min. speed.

5. Adjust the TEMP. potentiometer to temperature equal to the ambient

temperature.

6. e motor / fan will run at min. speed and speed up if the ambient temperature

rises ( hold the temperature probe in your hands to check).

7. Adjust the temperature potentiometer to the min. position (5 °C for GTE21-60-

DM and GTE21-60-DT or 15 °C for GTE-1-60-DM and GTE-1-60-DT)

8. e motor will run at max. selected speed if the difference between the setpoint

temperature and the ambient temperature is more than the value of the selected
proportional range.

9. If the unit does not operate as explained above, check the connections and

settings.
