Protection Relays Alternating Relays ARP SERIES Alternating Relay Description 8-PIN 11-PIN Wiring Diagram SPDT 8-PIN DPDT 11-PIN L1 L1 N/L2 N/L2 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. LED’s 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. 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. Note: Input voltage must be applied at all times for proper alternation. The use of a solid-state control switch for S1 may not initiate alternation correctly. S1 voltage must be from the same supply as the unit’s input voltage (see connection 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. Relay contacts in above are isolated.
