Using the flat blade (or Phillips) screwdriver, gently tighten the two screws to secure the MSB to the heat sink (8 in-lbs max. ).

(Note: The maximum operating current for each preset is 1. 5 mA DC. ) Figure 5 - MSB Terminal Block TB1 Connection Diagrams Switch Form C Contacts Open Collector 4. 2 Motor direction for each preset is selected by the position of Jumper R/F (Reverse/Forward). All presets have been factory set for Forward Motor Direction (Jumpers R/F set to the "F" position). Figure 6 - Motor Direction Selection (Jumper R/F) Forward Motor Direction (Factory Setting) Reverse Motor Direction (Jumper R/F In "F" Position) (Jumper R/F In "R" Position) 4. 3 To improve the resolution of the trimpots, several ranges are provided. The motor speed range for each preset is selected with Jumpers HI and LO. All speed range jumpers have been factory set for Full Speed Range (Jumpers LO and HI installed). (Note: The maximum speed is based on the MAX Trimpot setting. ) Figure 7 - Speed Range Selection (Jumpers LO and HI) Full Speed Range (0 - 100 % of MAX Speed) (Factory Setting) Low Speed Range (0 - 50 % of MAX Speed) Medium Speed Range (33 - 66 % of MAX Speed) High Speed Range (50 - 100 % of MAX Speed) (Jumper LO Installed) (Jumper HI Installed) (Jumper LO Installed) (Jumper HI Not Installed) (Jumper LO Not Installed) (Jumper HI Not Installed) (Jumper LO Not Installed) (Jumper HI Installed) 4. 4 The speed for each preset can be fine tuned using the adjustable trimpots. [. . . ] Operating the motor above it's rated frequency will linearly reduce the motor torque to 50% at full output frequency (120 Hz for 60 Hz motors and 100 Hz for 50 Hz motors).
