Equalizing run times increases equipment life and provides additional capacity.

EQUALIZING THE RUN TIME OF MULTIPLE LOADS

Alternating Relays are used in applications where the optimization of load usage is required by equalizing the run time of multiple loads. When identical loads are used for the same jobs, a standby unit is typically available in case the first load fails. However, an idle standby unit might deteriorate due to lack of use and is not a reliable backup. Alternating relays prevent this by assuring that multiple loads get equal run time.

CONTROLLING MULTIPLE LOADS FOR ADDITIONAL CAPACITY

Alternating Relays can also be used where multiple loads are on at the same time for additional capacity, if one load cannot keep up with demand. This alternating action is normally initiated by a control switch such as a float switch or pressure switch. Each time the initiating switch is opened, turning off a load, the alternating relay will change state, thus alternating between multiple loads. Typical applications include pump/motor units with float switches as the initiating contact, or compressors with pressure switches, or thermostats as the initiating contact.

DUPLEX AND TRIPLEX CONTROL OF LOADS

Macromatic offers two types of Alternating Relays: Duplexor: For controlling two loads with both plug-in (ARP Series) and Flange enclosure (ARF Series) for inner-door mounting, in SPDT, DPDT and DPDT Cross- Wired output configurations. ARP Series Duplex Controllers provides Sequence On - Simultaneous OFF (S.O.S.O.) operation with three switch inputs. Triplexor: For controlling up to three loads with plug-in enclosures (ATP Series). An optional top-mounted switch allows it to be used as a Duplexor until system expansion requires an added third load.
