Wiring
NOTE: All wiring must conform to national and local
codes and regulations (NEC, CE, and so on).
Do not use autotransformers. Use earth ground
isolating step-down Class 2 power supply
transformers.
Determine supply transformer rating by summing total
VA of all actuators used. The maximum rating for a
Class 2 step-down transformer is 100 VA.
It is recommended that no more than 10 actuators are
powered by one transformer.
Parallel Control of Actuators
SAX81.0-3U -Three-position actuators must have their
own specific controller.
SAX61.03U - Up to 10 actuators can be driven in
parallel from a single controller output with a rating of
1 mA. Modulating actuators have an input impedance
of 100KΩ.
NOTE: Use either a Phillips head screwdriver or a flat-
blade screwdriver to remove the wiring
compartment housing cover for access to the
terminal block and DIP switches.
DIP Switch Setting (SAX61.03U only)
Switch 1: Control Signal
Select between 0 to 10 Vdc or 4 to 20 mA input signal
for terminal Y (0 to 10 Vdc default).
Switch 2: Flow Characteristic
Do not change the flow characteristic switch. The
proper flow characteristic is designed into the Flowrite
599 Series valve.
NOTE: Changing the default setting will modify an
equal percentage valve to a linear flow
characteristic. When set to default, the flow
characteristic is determined by the valve
body.
