  • Control signals by closing contact, pressure switch 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, two secs. Then they will force the operation of the second electric pump, two seconds. Then force the operation of the third electric pump. The electric pumps in operation will switch off, respectively “P3”, “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 alarm command “FA” – lack of water – (4 – 6) remains open for more than 20 seconds, the relay will disarm the control contacts of the electric pumps and enter the alarm mode (11-1). Relay will disarm the alarm 3 minutes after confirming the existence of water in the tank given by the command (4-6).
