Descrição do produto

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

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.


Applications

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)

Operation

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.
