Description
DescriptionDescription
The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows
selection of alternation or either load for continuous operation. 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.

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. T o 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.

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.

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.
Dashed lines are internal connections.
