VSI SF-PB Quick Setup Manual

     
The SF-PB or SF-PC control pack, when shipped together with a Series 1000-X actuator,
!
is factory calibrated and set for 90° rotation; NO ADJUSTMENT IS NECESSARY. If you are
replacing an SF-PB or SF-PC setting of the position limits is MANDATORY before use.
NOTE: ACTUATOR IS EQUIPPED WITH MECHANICAL STOPS. THESE ARE FOR MANUAL OPERATION
ONLY AND SHOULD NOT BE USED TO SET THE POSITION LIMITS ON THE ACTUATOR.

INITIAL SETUP

If not connected to the actuator, install the SF-PB or SF-PC by plugging the three cables from the
actuator into the unit. Connect the appropriate power to terminals 1&2. Connect the control signal to
terminals 3&4. The control signal is polarity sensitive and must be correctly connected positive (+)
and negative (-).
If feedback is being used, connect the wiring to terminals 5&6. The SF-PB and SF-PC provides
position feedback of 4-20mA. If 2-10Vdc feedback is required apply a 500 ohm resistor in parallel
across terminals 5&6.
At this point, the Green LED "L1" should be illuminated. If Red LED "L2" is illuminated then the
control signal is faulty or SC switch in Figure B above is not set correctly for your control signal.
Ensure the SC switch is set for your input control signal (2-10V or 4-20mA). Once there are no Red
LED's illuminated, your actuator is ready to operate. Increase/decrease your control signal to confirm
proper operation. See the chart below for failure mode conditions on the SF-PB control pack.
