Product description

Alternating relay for alternating control of two electropumps, control of lack of water in the tank and alarm output.


Applications

  • Alternating control of two electropumps and water level control inside the tank
  • Signals of control by closing contact, pressostat and internal timing
  • Alternating voltage for water supply probe

Operation

Power the relay (green led on – A.1)

Two secs. after closing the contact pair “P1” (5 – 6) requires the operation of an electric pump. If the contact pair “P2” (7-6) closes, after two secs. it forces the operation of the respective electric pump. The electric pumps in operation will switch off, respectively “P2” and “P1” respectively.

When the pair”P1″ is closed again, the first electric pump to be started will be the next in the sequence of the alternation.

Terminal 1 is common to relay outputs 3, 9 and 11, for motor control and alarm, respectively.

Whenever the “F.A.” alarm command – lack of water – (4 – 6) remains open for more than 20 secs. The relay will disarm the control contacts of the electric pumps and enter the alarm mode (11-1). The relay will disarm the alarm 3 minutes after confirming the existence of water in the tank given by the command (4-6).
