Chapter 3: Programming

17 Outputs = 207 Setpoints Available

23 Outputs = 181 Setpoints Available

29 Outputs = 161 Setpoints Available

Refer to the Section 3.5: Selecting Number of Outputs.

3.12: Electronic Offset

The offset key is used to synchronize the digital display with the actual machine position. The Series

1995B PLS has full scale factor offset capabilities, and the offset is held in nonvolatile memory. How-

ever, to eliminate possible problems in the event that a replacement PLS is required, it is good practice

to mechanically synchronize the resolver with the machine and then use the offset key to make final, fine-

tune adjustments.

Programming the Electronic Offset

A)

Unit must be in the “Program” mode.

B)

Stop machine at a known location.

C)

Depress . After this sequence is

completed, the display will change to the position entered. The display and outputs are now

synchronized with the actual machine position.

3.13: Motion Detector

A programmable Motion Detect output will energize a relay when the transducer speed exceeds the

customer’s preprogrammed RPM value.

The motion detector is set by entering the following:

A)

Unit must be in the “Program” mode.

B)

The motion detect must first be enabled before you can store any values. To accomplish this,

depress . A one (1) will enable the motion
