CHAPTER FIVE: CONFIGURATION
5.1 INTRODUCTION:
Each amplifier has several configuration options. This chapter describes these options and how to
implement them. If desired, CONTREX will be happy to pre-configure your amplifiers.
NOTE: Each amplifier module is configured and shipped according to the model number (instructions to
construct a model number is in chapter three) when the order is placed. It is important for the
user to realize that any adjustment on the dip-switches by the user will result in discrepancies
between the model number and the actual configuration of the amplifier.
5.2 LOGIC INPUT CONFIGURATION:
There are five logic inputs: Limit +, Limit -, Inhibit, Reset In, Motor Temp. The first four may be
configured for active-high or active-low signals, and pulled-up or pulled-down termination (type A, B, C,
and D). The motor-temp may be configured for active-high or active-low signals, and is always pulled-up
(type A, and C). All five logic inputs have a selectable 0 to +5VDC or 0 to +15VDC range.
Type "A": Requires grounding of input to disable the amplifier (pull-up, active-low).
Type "B": Requires a positive voltage at input to disable the amplifier (pull-down, active-high).
Type "C": Requires grounding of input to enable the amplifier (pull-up, active-high).
Type "D": Requires a positive voltage at input to enable the amplifier (pull-down, active-low).
