Connection Diagram
Voltage loss over distance is caused as a function of control amperage multiplied by the resistance of
the wiring, and may be expressed:
Voltage loss =
(
wire resistance
)
X
(
control amperage
).
This
limits pushbutton control wiring to the following schedule:
16 ga. wire= up to 125 feet max
12 ga. wire = up to 300 feet max
14 ga. wire = up to 200 feet max10 ga. wire = up to 500 feet max
For applications requiring pushbutton controls from a long distance, or circuits of limited current,
order the factory modification, long range interface. The following schedule indicates the improved
control range using the long range interface:
16 ga. wire = up to 50 miles
20 ga. wire = up to 19 miles
18 ga. wire = up to 30 miles
22 ga. wire = up to 12 miles
Be certain to remove factory-installed jumper (#2 to #4) and also verify that no other external stop
button is connected at #2 and #4.
When the long range interface option is used in conjuction with a pushbutton control, connect to the
operator as shown below:
