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. 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.
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
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.
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.
