Fan Pump 2-Wire - Baldor VS1GV21-1B Installation & Operating Manual

5.5.5 Fan Pump 2-Wire

Operation in the Fan Pump 2-wire mode is controlled by the opto isolated inputs at J2-8 through J2-16. The opto inputs can
be switches as shown in Figure 5-9 or logic signals from another device.
J2-8 CLOSED allows normal control operation.
OPEN disables the control and the motor coasts to a stop.
J2-9 CLOSED operates the motor in the Forward direction (with J2-10 open).
OPEN motor decels to stop. Note: J2-9 and J2-10 are both closed = Fault Reset.
J2-10 CLOSED operates the motor in the Reverse direction (with J2-9 open).
OPEN motor decels to stop. Note: J2-9 and J2-10 are both closed = Fault Reset.
J2-11 CLOSED selects Analog Input 1 (if J2-13, J2-14 and J2-15 are closed).
OPEN selects Command Source (Level 1, Input, Command Source) if J2-13, J2-14 and J2-15 are closed.
J2-12 CLOSED selects STOP/START and Reset commands from terminal strip.
OPEN selects STOP/START and Reset commands from Keypad.
J2-13 CLOSED allows other selections, see Speed Select Table 5-5.
OPEN selects speed commanded from Keypad (if J2-14 and J2-15 are closed).
Note: When changing from Terminal Strip to Keypad (J2-12 or J2-13) the motor speed and direction will remain
the same after the change.
J2-14 Firestat. Selects Level 1, Preset Speeds, Preset Speed 1.
J2-15 Freezestat. Level 1, Preset Speeds, Preset Speed 2 (if J2-14 is closed).
J2-16 Optional External Trip input (not required). If used, you must set Level 2 Drive Protect block, External Trip to "ON".
CLOSED allows normal operation.
OPEN causes an External Trip to be received by the control (when programmed to "ON").

Note: When command source is a unipolar signal (0-10V, 0-5V, 4-20mA etc.) and forward or reverse are closed, motion will
occur (unless both are closed at the same time).
