Press [Setup] key and press [LIMIT TABLE] soft key to open <LIMIT TABLE SETUP>
page.
This page allows you to configure the AT281x’s built-in comparator.
AT2818/AT2816X/AT2817A’s built-in comparator can sort DUTs into a maximum 10
levels (BIN1 through BIN9 and OUT) using up to nine sets of primary parameter limits
along with one set of secondary parameter limits.
AT2817A’s built-in comparator can sort DUTs into a maximum 4 levels (BIN1 through
BIN9 and OUT) using up to nine sets of primary parameter limits along with one set of
secondary parameter limits.
In addition, DUTs that fall within the primary parameter limits but are out of the
secondary parameter limits can be sorted into an auxiliary bin.
To take full advantage of the comparator, AT281x was equipped a handler interface for
use in conjunction with the comparator. All 14 bins signal can output to yours PLC via
the handler interface.
In the <LIMIT TABLE SETUP> page, you can configure each of the following controls
with the cursor placed in the corresponding field.
Comparator ON/OFF [COMP]
*1
Auxiliary bin ON/OFF [AUX]
*1
Nominal value [NOM]
Primary parameter comparator limit mode [MODE]
Beep feature [BEEP]
*2
Primary parameter total bins [BINS]
NOTE:
*1. This two setting also can be set in the <BIN NO. DISPLAY> page.
*2. This setting also can be set in the <SYSTEM CONFIG> page.
