Remoto was founded in 1986 in the North region of Portugal, as a manufacturer
and import agent.

After 1992 the company focused exclusively in the industrial area, through the
production of its main article, the Level Regulator – RNC 1002, for sewage level

The environmental concerns, in the year of 2000, brought improvements in the
product with the introduction of mechanical components in its operation. This
change was marked by using green color in the product.

Currently Remoto is level regulator manufacturing market leader in the Iberic
peninsula, fulfilling all the requirements for its Certified Quality System, and
developing national and international partnerships.

Alternating Relay 2 Pumps - RAL 202 SAM

Alternating relay for 2 electropumps for sanitation plants, with maximum alarm.

Of its main characteristics, we highlight the box of 2 modules, the detection of the float fault of minimum level and also, the fact that the various timings can be adjusted by Micro Switch, which gives high flexibility and resource savings.

Command and protection of electropumps installed in sanitation systems, with 2 electropumps, with:

  • Inputs - minimum level, toggle, boost and maximum / alarm.
  • Output relays - B1, B2 and alarm electrodes control.
  • Reinforcement timing for support pump inlet.
  • Pump start delay - selectable internal timing.
  • Pump stop distance - 2 sec. of interval.
  • Lack of alternating signal - connect the 2 pumps by the reinforcement. Signal alarm.
  • Maximum alarm - A timed 5 or 15 sec command is started. commanded by the maximum buoy. (dip-switch selection)

Power the relay (green led on – A.1)
When powering the relay will turn on all the LEDs sequentially for testing lamps.

Alternating and Reinforcement Input
During each actuation of the toggle signal, alternately outputs B1 and B2.
If a boost actuation appears during the alternating operation, it will switch on the second available output.
The outputs B1 and B2 will switch off in the same sequence as the ones they connected in the absence of the minimum signal.

Reinforcement Timing
Selecting the respective micro-switch changes or shifts the boost timing.

Alternation and Reinforcement Boom Failure
Due to the absence of the alternating buoy signal, the two pumps will only turn off in order of the booster float.
Due to the absence of signal from the two buoys, the pumps will only turn on the alarm buoy, and turn off by the minimum buoy. Actuates the alarm output relay.

Lack of signal of minimum buoy
In the absence of the minimum buoy signal, the system will run in command timed by the maximum float, connecting the two pumps.
When the maximum buzzer is turned off, the delay time of 5 or 15 seconds starts, at the end of which the two pumps are switched off.

Maximum / Alarm Input
This input is available to receive an alarm signal by High Level (float). When activated it signals alarm, it turns on the alarm output relay and the two pumps (B1 and B2). The alarm cancels when the level is reset.

Displacement at start of pumps (Water hammer)
When the start and stop commands are given simultaneously, the outputs B1 and B2 do not switch simultaneously, but with a time offset equal to 3 or 10 seconds. according to the position of the micro-switch.

Misalignment of pumps
Whenever the two outputs are switched on and the order to switch off occurs, these outputs do not switch off at the same time, but with a 2 sec.

Maintenance Cycle
If there is a minimum level float condition for more than 60min., Without the condition of the toggle float, an electric pump will be connected, which will only turn off when deactivating the minimum float.

“The level regulators RNC1002 have a excellent relation between quality/price, and are clearly the best option for a good and reliable operation in this type of installations”

João Lourenço
Economist – Regacentro Sales Director


“Remoto level regulators are, since many years, our favourites for many reasons: reliability, easy operation, quality/price relation.
In pumping stations, a failure in the level regulation can cause malfunctions in the pumps and/or floods with severe consequences, that is why, when it comes to take a decision for quality, we don’t hesitate!”
