Power the relay (green led on – A.1)
The closing of the contact pair “RN0” (4-6) leaves the relay in standby mode. If the contact pairs “RN1” (5-6) and “RN2” (7-6) close, they will force the operation of the sewage pump one and two, respectively.
If the “RNA” contact pair (8-6) is closed, the high level alarm signal will light up, and the relay automatically closes the “AL.NA” (3-1) pair of contacts and activates a remote alarm. The alarm goes off when the “RNA” contacts (8-6) open.
The two electric pumps only switch off after the “RN2” (7-6), “RN1” (5-6) and “RN0” (4-6) contacts open. Terminal 1 is common to relay outputs 3, 9 and 11 for alarm control and motors, respectively.
