VSI 1000-X Series Quick Setup Manual

FIGURE A
The SF-LB control pack, if shipped together with a Series 1000-X actuator, is factory calibrated and
set for 90° rotation and no adjustment should be needed. However, if you are replacing the SF-LB
or the factory settings do not conform to your actuator/valve application, some adjustment may be
necessary.

INITIAL SETUP

If the SF-LB is not installed – install in the actuator by plugging in the two cables into the unit. Con-
nect the appropriate power to terminals 1&2. Connect the control signal to terminals 3&4 and note
that the polarity must be positive and negative.
If feedback is being used connect the wiring to terminals 5&6. The SF-LB provides position feedback
of 4-20mA.
At this point the Green LED "L1" should be illuminated. If red LED "L2" is illuminated then the control
signal is faulty or SC is not set correctly for your control signal. Ensure that SC is set for your applica-
tion control signal (2-10V or 4-20mA). See the chart below for failure mode conditions on the SF-LB
control pack. Your actuator should be ready to operate.
