Toggle relay for alternating control of two electropumps, with high sewage level control and alarm output (for horn)
Control signals by closing contact, pressure switch and internal timing
Designed to be used in sewage, with RNC1002 sewage level regulator
- Alternating command of two electropumps and high level control of the liquid to be pumped
- Signals of control by closing contact, boiadores and internal timing
- Output available for audible alarm due to high level of sewage
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.
