Alternating Relay ARP Series The ARP Series is used in systems where equal Features: run time for two motors is desirable. The selector switch allows selection of alternation of either load • Provides equal run time for two motors for continuous operation. LED’s indicate the status • Alternating or electrically locked operation of the output relay. This versatile series may be • Low profile selection switch front panel mounted (BZ1 accessory required) or • 10A output contacts 35 mm DIN rail mounted with an accessory socket. • LED status indication • Industry standard base connection For more information see: Approvals: Appendix B, page 167, Figure 31 for dimensional drawing. Appendix C, 170, Figure 29 for connection diagram. Auxiliary Products: • Hold-down clips (sold in pairs): P/N: PSC8 (NDS-8) P/N: PSC11 (NDS-11) • Panel mount kit: P/N: BZ1 Operation • 11-pin socket: P/N: NDS-11 Alternating: When the rotary switch is in the “alternate” position, alternating operation of Load A and Load B • 8-pin socket: P/N: NDS-8 occurs upon the opening of the control switch S1. To terminate alternating operation and cause only the selected • DIN rail: P/N: C103PM load to operate, rotate the switch to position “A” to lock Load A or position “B” to lock Load B. The LEDs indicate the status of the internal relay and which load is selected to operate. Note: Input voltage must be applied at all times for proper alternation. The use of a solid-state control switch Available Models: for S1 may not initiate alternation correctly. S1 voltage must be from the same supply as the unit’s input ARP23S ARP43S voltage (see connection diagrams). Loss of input voltage resets the unit; Load A becomes the lead load for ARP41 ARP61S the next operation. ARP41S ARP63 Duplexing (Cross Wired): Duplexing models operate the same as alternating relays and when both the Control ARP42S ARP63S (S1) and Lag Load (S2) Switches are closed, Load A and Load B energize simultaneously. ARP43 The DPDT 8-pin, cross-wired option, allows extra system load capacity through simultaneous operation of both motors when needed. Relay contacts are not isolated.
