LIMSW_2
_
HYSTERESIS
0
O/S
Sets the hysteresis of limit switch 2 to be applied
for resetting the LIMSW_2_VALUE_D to OFF after
LIMSW_2_TARGET went beyond LIMSW_2_SETPOINT
and LIMSW_2_VALUE_D turned ON (when used as a
high-limit switch), or after LIMSW_2_TARGET went below
LIMSW_2_SETPOINT and LIMSW_2_VALUE_D turned
ON (when used as a low-limit switch).
44
2044 LIMSW_2_UNIT
—
—
Indicates the unit set in LIMSW_2_TARGET.
45
2045 ALARM _PERFORM 0x1070
AUTO

and disable specifi c alarm(s); write zeros to the respective
bits in this parameter to disable desired alarms. (For
details, refer to APPENDIX 3 "OPERATION OF EACH
PARAMETER IN FAILURE MODE.")
46 2046
