TRANSFORMER CONTROLLER

PRODUCT DESCRIPTION

e RTR-1 series of transformer fan speed controllers regulate the rotational speed

of single-phase voltage controllable motors by varying the output voltage. ey

are equipped with an auto-transformer and control the speed manually in steps

via a remote device, e.g. a switch or thermostat. e technology used provides a

regulated output voltage with a perfect sinusoidal shape.

MOUNTING INSTRUCTIONS IN STEPS

Before you start mounting the unit, read carefully “Safety and Precautions”.

Choose a smooth solid surface for installation (a wall, panel, etc.).

Follow these steps:

1. Unscrew the front cover and open the enclosure.

2. Fix the unit onto the wall or panel using the provided screws and dowels. Mind the

correct mounting position and unit mounting dimensions. (See Fig. 1 Mounting

dimensions and Fig. 2 Mounting position.)

3. Pay attention to the following instructions in order to minimize the operating

temperature:

3.1 Respect the distances both between the wall / ceiling and the device and

TRANSFORMER CONTROLLER

between two devices as shown in Fig. 2. In order to ensure suﬃcient

ventilation of the controller, clearance on every side has to be maintained.

3.2 When installing the device, please keep in mind that the higher you install

it, the warmer the device will get. For example, in a technical room the

correct installation height can be of great importance.

3.3 If maximum ambient temperature cannot be adhered to, please provide

extra forced ventilation / cooling.

Not respecting the abovelisted rules can reduce service life and relieves the

manufacturer of any responsibilities.

4. Insert the cables through the cable glands and do the wiring according to the

wiring diagram (see Fig. 3) while adhering to the information from section

“Wiring and connections” above.

4.1 Connect the power supply line (terminals L, N and protective earth).

4.2 Connect the motor(s) (terminals U, N and protective earth).

4.3 Connect the external switch (e.g. Sentera’s SMT-1-30-4C) (terminals P and

1, 2, 3, 4, 5 as indicated in Fig. 3 below)

4.4 If applicable, connect the unregulated output (L and N). It can be used to

supply a 230 VAC valve, lamp, etc. e unregulated output is active when

the supply voltage is present.

ATTENTION A safety isolator / disconnect switch should be installed on the mains electricity

side of all motor drives.

ATTENTION Make sure the connections are correct before you power the unit.

5. Close the cover and secure it with the screws.

6. Tighten the cable glands.

7. Switch on the mains supply.

8. e controller needs to be switched on via the external switch.

9. Make sure the transformer controller can operate normally (consider an isolating

switch).

10. Turn the external switch into the relevant positions to adjust the output voltage.

Optional settings

e standard conﬁguration of the output voltages is as indicated in Table 1 below.

** Because more than 5 output voltages are available, it is possible to adjust the

steps by changing the internal wiring.

VERIFICATION OF INSTALLATION

ATTENTION A safety isolator / disconnect switch should be installed on the mains electricity

side of all motor drives.

Safe operation depends on proper installation. Before start up, ensure the following:

■e mains supply is connected correctly.

■Protection is provided against electrical shock.

■e cables are the appropriate size and fuse-protected.

■ere is suﬃcient air ﬂow around the unit.

ATTENTION e unit is supplied with electrical energy at voltages high enough to inﬂict personal

injury or threat to health. Take the relevant safety measures.

ATTENTION Disconnect and conﬁrm that there is no live current ﬂowing to the unit before servicing.

ATTENTION Avoid exposing the controller to direct sunlight!

TRANSPORT AND STORAGE

Avoid shocks and extreme conditions; stock in original packing.
