AMETEK 1995L Micro-Set PLS - Manual (Page 14)

Chapter 3: Programming
Installation and Maintenance Manual 10
On units without Multiprogram, setpoint availability is dependent on the number of outputs enabled.
6 Outputs = 253 Setpoints Available
12 Outputs = 242 Setpoints Available
18 Outputs = 207 Setpoints Available
24 Outputs = 181 Setpoints Available
30 Outputs = 161 Setpoints Available
Refer to the Section 3.5: Selecting Number of Outputs.
3.13: Electronic Offset
The offset key is used to synchronize the digital display with the actual machine position. The Series
1995L PLS has full scale factor offset capabilities, and the offset is held in nonvolatile memory.
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.

3.14: Reset-to-Preset
Remote Reset-to-Preset Value - This option allows the position of the PLS to be reset to a keypad
selected value; this value would be based on an input from a remote contact or proximity switch
mounted at a known location on the machine. Typical uses are to synchronize outputs with the leading
edge of products moving through a machine.
The reset-to-preset function of the 1995L requires an isolated contact closure. The isolated contact is
used as an input to the 1995L PLS; which upon closure, will reset the unit to its preprogrammed reset
value. If an auxiliary contact is available, it can be wired to the 1995L PLS to perform this function. If
an auxiliary contact is not available, a reset input relay (Part No. SD0395100) can be purchased and
wired to a 110V AC circuit to provide this output.
