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. then will force 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 closed for more than 20 secs. The relay will disarm the control contacts of the electric pumps and will set the alarm (11-1), and turn on the led “A.L.” – water-out alarm.
