Temperature High Alarm (V5012); Temperature Deviation Alarm (V5013); Alarm Deadband (V5014); Setpoint Low Limit (V5015) - FACTS Engineering Direct Logic 405 Manual

Temperature High Alarm (V5012)

The Temperature High Alarm occurs when the temperature rises above the value programmed in this
location. This value is read by the temperature controller when bit 0 of the Mode Word is set.

Temperature Deviation Alarm (V5013)

The Temperature Deviation Alarm occurs when the temperature is further from the SetPoint than the
value programmed in this location. Bit 5 of the Mode Word enables reporting of this alarm. If bit 5 of the
Mode Word is not set then the Temperature Deviation Alarm will not be reported. This value is read by
the temperature controller when bit 0 of the Mode Word is set.

Alarm Deadband (V5014)

The Alarm Deadband lets you program a deadband around each alarm. Deadband prevents alarms from
chattering when near an alarm limit. This value is read by the temperature controller when bit 0 of the
Mode Word is set.

SetPoint Low Limit (V5015)

Bit 6 of the Mode Word enables SetPoint clamping. If it is on then the SetPoint Low Limit is the lowest
value that can be used as a SetPoint. If a lower SetPoint is programmed (V5001) then it will be clamped
to the SetPoint Low Limit. This value is read when bit 0 of the Mode Word is set.

SetPoint High Limit (V5016)

Bit 6 of the Mode Word enables SetPoint clamping. If it is on then the SetPoint High Limit is the highest
value that can be used as a SetPoint. If a higher SetPoint is programmed (V5001) then it will be
clamped to the SetPoint High Limit. This value is read when bit 0 of the Mode Word is set.
