- Ultra Low Energy Dryer
UT2 - Purge Heater Update Time
[ULTRA-600 and ULTRA-1000 only]
format:
xxxyy (seconds / seconds)
function(s):
xx:
Amount of time between purge heater PID updates when the actual
purge
air temperature is
above
setpoint.
yyy:
Amount of time between purge heater PID updates when the actual purge air
temperature is
below
setpoint.
OT2 - Purge Heater Over-Temp Alarm
[ULTRA-600 and ULTRA-1000 only]
format:
xxxyy (seconds / °F or °C)
function(s):
xxx:
Amount of time that the heating hopper inlet air temperature must be
above
setpoint before a Purge Heater Over-Temperature alarm is
triggered.
yy:
Number of degrees that the heating hopper inlet air temperature must be above
setpoint before a Purge Heater Over-Temperature alarm is triggered.
NH2 - Heating Hopper Heater No Heat Alarm
[ULTRA-600 and ULTRA-1000 only]
format:
xxxxx (seconds)
function(s):
Maximum amount of time after the purge heat cycle begins during which one of the
following two conditions must be detected:
1. the purge air temperature must climb 20 degrees
2. the purge air temperature must move at least 20 percent toward the target
If neither condition is met, a “NO HEAT” alarm will be triggered.
SO2 - Purge Heater Setpoint Offset
[ULTRA-600 and ULTRA-1000 only]
format:
xxxyy (seconds / °F or °C)
function(s):
xxx:
Amount of time at the beginning of a purge heat cycle to temporarily
target
a lower temperature. This is to mitigate the inherent overshoot of a
PID loop.
yy:
Difference, in degrees, from the current purge air temperature target and the
temporary temperature target.
DPD - Dry Purge Delay
[ULTRA-600 and ULTRA-1000 only]
format:
xxyyy (seconds / seconds)
function(s):
xx:
The amount of time between the purge air solenoid valve opening and the
purge air heater powering-up
yyy:
The amount of time between the purge air heater powering-down and the purge
air solenoid valve closing.
