Protection Relays Alternating Relays ARP SERIES Alternating Relay Description The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows selection of alternation or for continuous operation of either load. LEDs indicate the status of the output relay. This versatile series may be front panel mounted (BZ1 accessory required) or 35 mm DIN-rail mounted with an accessory socket. 8-PIN Operation Alternating: When the rotary switch is in the alternate position, alternating operation of Load A and Load B occurs upon the opening of the control switch S1. To terminate alternating operation and cause only the selected 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. 11-PIN Note: Input voltage must be applied at all times for proper Wiring Diagram alternation. The use of a solid-state control switch for S1 may not initiate alternation correctly. S1 voltage must be from SPDT 8-PIN DPDT 11-PIN the same supply as the units input voltage (see connection L1 N/L2 L1 N/L2 diagrams). Loss of input voltage resets the unit Load A becomes the lead load for the next operation. Duplexing (Cross-Wired): Duplexing models operate the same as alternating relays and when both the Control (S1) and Lag Load (S2) Switches are closed, Load A and Load B energize simultaneously. 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. DPDT 8-PIN CROSS-WIRED Relay contacts in above are isolated.
