E8024 TIR Operation
Install a part into the gage fixture. Press the Reset Push Button. Rotate the part 360 degrees. The
bargraph display will rise and stop at the maximum TIR reading. If the reading is in excess of the
maximum limit light set point, the Red indicator will illuminate. Otherwise the Green indicator will
remain illuminated.
+/- Peak Operation
When utilizing either the + and - peak modes, rotate the Mode Switch to the desired position. The
gage is set up the same as the TIR operation. Operation in the peak modes is the same as the TIR
mode, except the bargraph display will have a center position zero. Press the Reset Push Button to
clear the module memory. Rotate the part 360 degrees. The displayed readings will be either the
maximum (+ peak) or minimum (- peak) reading obtained during part rotation.
Average Operation
When utilizing the Average mode, rotate the Mode Switch to the Avg. position. The gage is set up
the same as +/- Peak operation. Operation in the average mode is the same as the +/- Peak mode.
Press the Reset Push Button to clear the module memory. Rotate the part 360 degrees. The dis-
played readings will be the average of the readings obtained during part rotation.
Remote Interface
Two user control lines, present on the I/O connectors located on the rear panel of the Trendsetter™
column allowing an external controller to command four special operating modes as follows:
1. Reset — All latched readings cleared, limit lights and logic outputs off.
2. Follow — Normal operation, limit lights and logic output follows the signal input.
3. Latch & Follow — Limit lights and logic output follow the signal input and latch on any
over or under excursions. Latched readings are cleared by returning to either Reset or
Follow Mode.
4. Hold — Limit lights and logic output are locked into their present status and ignore any
signal input. This condition is cleared by returning to either Reset or Follow Mode.
The remote interface is active for all positions of the Mode Switch. To use, determine the function
use the Truth Table below. Apply 5-24 VDC to the I/O pins listed. These commands must be posi-
tive with respect to the user common Pin 24.
