Descrição do produto

Alternating relay for alternating control of three electropumps, control of lack of water in the supply network.
Signals of control by closing contact, boiadores and internal timing.
Alternating voltage for water supply probe.


Applications

  • Alternate control of three electric pumps and control of lack of water in the supply network
  • Control signals by closing contact, pressure switch and internal timing
  • Alternating voltage for water supply prob

Operation

Power the relay (green led on – A.1)

Two seconds after the closing of the contact pair “P1” (5-6) requires the operation of an electric pump. If the contact pair “P2” (7-6) closes, two secs. Then force the operation of the second electropump. Two seconds after closing the contact pair “P3” (6 – 8), the third electric pump is required.

The electric pumps in operation will switch off, respectively “P3”, “P2” and “P1”

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 controlling the motors.

Whenever the “F.A.” alarm command – no water supply – (4 – 6) remains closed for more than 20 seconds, the relay will disarm the control contacts of the electric pumps and enter the alarm mode.

The relay will disarm the alarm 3 minutes after confirmation of water supply from the control unit (4 – 6).
