1.
Q? The drive will not start!
A! There are several different things which can cause such a situation. First and foremost, MAKE SURE THERE IS A CLOSED CONNECTION BETWEEN TERMINALS 7 AND 8. Ninety-five percent of the calls to us about the drive not starting is simply this connection. If you have the connection closed, and have NOT changed any parameters out of the box, make a closed connection between terminals 6 and 7. This will start the drive. You will need an external analog signal to terminals 1, 2, or 4. Otherwise, go and change parameter 59 to a "1," then you can use parameter 58 for a speed reference. Out of the box defaults are set for "Three Wire" control. If all else fails, reset defaults to the drive, and try the steps above.

Q? RF Filters do not come up in passport. What is the difference between Class A and Class A & B Filters?
A! New filter p/n's to meet CE with Series C drive can be found with this file here. Class A CE filtering is an standard for industrial type filtering. Class B is for residential area filtering. This will keep noise out of televisions and radios, where just a plain Class A may not.

Q? In the manual it shows that a Bulletin 140 can be used with a 160. Can you clarify how it should be used? The manual is a little unclear.
A! The Bulletin 140 manual motor starter can be used with the 160 for protection of an individual motor in a "Group Installation." To do this, one set of fuses or a UL489 rated circuit breaker must be ahead of the B140s to serve as the branch circuit protective device for the entire group. This must be sized appropriately for the sum of the individual motors in the group. Then, an individual B140 is used ahead of each 160 (within the group) for protection of the individual motor. The B140 cannot be sized greater than four times the rated output of the drive or 30A, whichever is greater. For example, take the 1/2Hp, 460V drive; which is rated 1.2A maximum output. Table 2.B in the 160 user manual shows a 6A B140 to be used with this drive. To use this device properly, the adjustment dial on the B140 must be set to 4.8A or lower.

Q? Why won't my remote keypad work with an older version of the 160?
A! The B160 remote keypads (160-P2, 160-P3) will only work with the Series C drive. The remote keypads talk to the drive via the microprocessor serial port. The Series A or B drive does not have the microprocessor serial port brought out to the control board connector that the remote programming adapter plugs into, therefore the remote keypads cannot communicate with the drive microprocessor.

Q? What version drives do the 160-RS1 serial module work with?
A! The 160-RS1 serial communication module will work with any Series drive because it talks to the drive via the microprocessor parallel port, which in all Series is brought out to the control board connector.
