Limit Hysteresis 0x4nn1 0x68 0x16 Set the hysteresis for the limit, which is how far
back into the safe band the temperature must
return before the limit can be cleared.
Limit Over-Temp Trip Point 0x8nn0 0x6D 0x34 Sets the high trip point where the over
temperature relay will open.
Limit Under-Temp Trip Point 0x8nn0 0x6D 0x35 Sets the low trip point where the under
temperature relay will open.
Limit Set Point Upper Bound 0x4nn1 0x68 0x17 Define the maximum settable trip point value.
Limit Set Point Lower Bound 0x4nn1 0x68 0x18 Define the minimum settable trip point value.

Description
Limit Temperature Reading 0x2nn0 0x65 0x14 Indicates the current temperature of the limit
sensor.
Limit Sensor Error 0x2nn0 0x65 0x01 Indicates if the limit sensor is valid or in error. If
the sensor is in error, the temperature reading
will return 9999.9C and be invalid. The limit
circuit will also open the relay on any sensor
error.
Limit Condition 0x6nn0 0x68 0x18 Indicates if a limit condition is occurring.
Limit Clear 0x3nn0 0x66 0x11 Write a 1 to this index to clear a tripped limit.
The limit can be cleared if:
1. The sensor reading is valid.
2. The temperature is within the trip
points.
