Product Description
Alternating Relay RA220
Alternation Command for hydropressor plant with 2 motors
Operation
Whenever the alternation command (6-8) (ALT) closes, the output relays (1-3) and (1-4) arm alternately. If the control (6-7) is closed (YES). the two output relays (1-3) and (1-4) are connected simultaneously. If this command reopens, the output relay that has been closed for the longest time will open. If only the alternation command is to be carried out and never the simultaneity command, only one of the control circuits (6-8) or (6-7) is used.
In order to avoid hydraulic shocks, the relay has a device that delays the cut-off or start-up of the second electric pump by approximately 2s, even if the simultaneity command has been carried out together with the alternation command.
