OBJECT

Chapter 1. Object

This manual is intended to help users to operate the RUT-4 power supply supervision relay.

Chapter 2. Range

The new family of power supply supervision relays is represented with an OP and comprises the
following models:

 RUT-4 OP: Supervision relay of the power supply with correct operation signalization.

 RUT-4 OP:2: Supervision relay of the power supply with both correct operation and under
voltage signalization.

Chapter 3. Operating principles

The RUT-4 OP relay is designed to supervise the voltage supply level. When the voltage level
matches the relays pick-up voltage level the relays contacts close and the green LED lights.

In the case of the RUT-4 OP:2 relay, there is also a red LED that signalises that the voltage level
is under the operational level.

Chapter 4. Reception & Storage

The RUT-4 OP, (RUT-4 OP:2) supervision relay is supplied with packaging capable of protecting
it during normal handling for equipment of this type.

If it is not to be installed immediately, it should be kept in the packaging, properly closed and in
indoor conditions, protected from rain, dust, vibration, etc.

If the packaging is damaged or it is believed that the unit may have been incorrectly handled in
transit, the carrier, the relevant insurance company and the manufacturing plant should be
informed forthwith.

OPERATIONAL CHARACTERISTICS

Check also that the data on the ID plate matches the order data.

Chapter 5. Operational characteristics

5.1. Supervision Functions

The RUT-4 OP relay monitors the supply of the circuit. It will initiate an alarm if the supply falls
below the assigned drop-out voltage (see table on page 8).

The supervision is done by an electromagnetic relay that will operate as long as the supply of
the circuit is over the assigned drop-out voltage of the relay. When the supply falls below the
operational range of the relay the four contacts will open and return to their release condition.
The RUT-4 OP has release time of more than 150ms. If the supply voltage interruption is less
than 150ms the RUT-4 OP will not perform any action.

5.2. Relay indicators

Correct operation of the RUT-4 OP is shown via:

 An illuminated green LED when the supply is over the minimum operational range.

 Four potential-free change-over contacts:

Correct operation of the RUT-4 OP:2 is shown via:

 An illuminated green LED when the supply is over the minimum operational range.

 An illuminated red LED when the supply is below the drop of voltage.

 Four potential-free change-over contacts:

FUNCTIONAL DIAGRAM.

Chapter 6. Functional diagram.

The graphic below shows the pick-up and drop-off of the RUT-4 OP and the corresponding effect
in the output contacts and the green and red LEDs. Note that the red LED is only available in the
RUT-4 OP:2.

This other graphic shows how an interruption in the supply of less than 150ms has no effect nor
in the contact outputs nor in any of the signalisation LEDs:

OPERATION

Chapter 7. Operation

The RUT-4 OP does not need any previous to use preparation. In the other hand, the RUT-4
OP:2 does have a before first use operation to do.

To be able to signalize with a red LED when there is no enough voltage in the circuit, the red
LED is supplied with a long-life battery installed inside the relay. When first installed, the front
switch must be activated in order to close the battery circuit. This is done so the battery
life is not reduced during transport or when is stocked.

Once the switch is activated the battery will only supply the red LED when there is an under
voltage, assuring a very long life for it. The battery life has been severely tested and can withstand
continuously supplying the red LED for more than a month in all the temperature range that the
relay withstands.
