Notes
Time Exceeded
Value 5 R/W T
Type 2 RO
Accumulated time of Limit SP exceed
conditions since this parameter was
last reset.
Modbus: Write any value to reset
ASCII: See Controller Command
00170 for reset
Limit Hysteresis 6 R/W F
Type 2, 3/4 R/W
A band on the “safe” side of the Limit
SP. Adjustable 0 to 100% of span. A
latched limit relay cannot be reset until
the process passes through this band
