4.4 Connecting to the Part handler (Handler Interface)
4-18 ZM2371/ZM2372

Handler interface operation timing
(a) Continuous drive (b) Triggered drive
(c) Measurement start timing (d) Measurement completion timing


Cable length of Handler interface
It should be preferably within 5m, or should not exceed 15m maximum. Use the shielded
cable to avoid noise emission and contamination.

Relation between enabled/disabled of comparator and handler interface signal
When handler is disabled, handler interface output is as below:
•
Comparison signal (Terminal corresponding to /BIN1 to /BIN14, /OUT OF BINS, /S-NG,
/ERR) fixed to high level (not output)
•
/EOM
、
/INDEX
Fixed to low level (always output)
The output immediately after power turned on is the same as above as well. Also, the
same state is established by the initializing operation with the initialize menu or system
setting menu or by the *RST command.
Regardless of enabled/disabled of comparator, input of handler interface is always enabled.
・
Input: TRIG, /KEY_LOCK, /RCL0 to /RCL4, /RCL-VALID
Remark:
When the
secondary
parameter is
Rdc, /INDEX
has high level
from the
reception of
trigger to the
completion of
signal
acquisition of
DC resistance.
