Operating princip leControl relays RM35 UA1pMW are designed for the monitoring of a.c. or d.c.

voltages.

They automatically recognise the form of thecora(50 or 60 Hz) signal.

Fault signalling is by LED.

Overvoltage and undervo ltage cont rol relays: RM35 UA11MW, UA12MW and

UA13MW

The operating mode is fixed by the user:

A switch allows selection between the following modes:Undervoltage with or without memory,

Overvoltage with or without memory.

The position of the switch, and therefore the operating mode, is read by the producton energisation.

If the switch is set to an unacceptable position, the product detects a fault, the output

relay stays open and the LEDs flash to signal the position error.If the switch position is changed while the device is operating, all the LEDs flash, butthe product continues to operate normally with the function selected at the time of

energisation preceding the change of position.

The LEDs return to their normal state if the switch is returned to the original position

selected prior to the last energisation.

The undervoltage or overvoltage threshold value is set by means of a potentiometer

graduated as a percentage of the scale value of Unto be monitored.

The hysteresis is adjusted by means of a potentiometer graduated from 550 % ofthe threshold setting.

The hysteresis value must not exceed the limit values of the measuring range.

In overvoltage mode, if the voltage controlled exceeds the threshold setting for a

time greater than that set on the front panel (0.330 s), the output relay opens andLED Rgoes out. During the time delay, this LED flashes.

As soon as the voltage drops below the value of the threshold setting, minus thehysteresis, the relay instantly closes.In undervoltage mode, if the voltage controlled falls below the threshold setting for

a time greater than that set on the front panel (0.330 s), the output relay opens

and LED Rgoes out. During the time delay, this LED flashes.

As soon as the voltage rises above the value of the threshold setting, plus thehysteresis, the relay instantly closes.

Memory mode:If Memory mode is selected, the relay opens when crossing of the threshold is

detected and then stays in that position.

The power must be switched off to reset the product.
