822-1002-C01 Datasheet, PDF (14/40 Pages) Magnetrol International, Inc. – Kotron® Sentinel Models 822, 832 and 842

The microprocessor-based Sentinel offers all operator func-
tions and setup procedures from the three tactile-feedback
keys described above. Due to the number of user program-
mable features included in the unit, the calibration flow
chart is extensive. The flow chart is modular, however, it
can be divided into five subsections or program paths
which are connected to a home base, or normal operating
mode, RUN (walking M or S). When letters scroll horizon-
tally across the LED and no error messages are displayed,
all systems are functioning properly. The calibration flow
chart structure is shown on page 12.
NOTE: If MagneCal precalibration data was entered at the
factory, use Advanced Calibration procedures (Section 2.5) in
conjunction with the standard calibration procedures.

In order to properly calibrate the Sentinel, the Calibration
instructions are broken down into the five PATHS
described below.
Access to program paths is granted with the following
key strokes:
