 Input Filter
Function
To avoid unstable PV display due to interferences, DTE10T offers the filter function. Instead of averaging the values, the filter function here
calculate the weighted average value of the “current PV” and “previous PV”.
The filter equation: PV (displayed value) = [previous PV x (filter times – 1) + current PV] / filter times
The bigger the filter times, the bigger the weight of the previous PV, and the smoother the temperature display, which is a good way to
suppress interferences.
How to Operate
Set up relevant parameters using the table below.
Parameter Address Default value Range
Filter times 10F7H 8 0~50
Filter range 10F9H 1.0 0.1~10.0
 Hot Runner Control
Function
The hot runner control includes 3 steps:
1. Heating up by constant output volume
2. Timed PID control (Soak)
3. Slope heating to the target temperature (SV)
How to Operate
1. Enable the hot runner control function: Write 1234H into the address 47F1H and then 0060H into address 4824H.

Notes:
 The flag to enable hot runner control is at bit6 of 4824H (and bit5 as to be enabled at the same time). Write 0060H to set both bits on.
 If there is already a set value in 4824H and you would like to modify it, reset it to 0 before you set up a new value.
2. Set up relevant parameters using the table below.

Example
Assume the temperature bound is 100.0, constant output volume is 35.0, timed time is 15, target temperature is 200.0 and slope is 20.0, thus
1. The heater outputs by the 35% constant volume and waits for the temperature to rise to 100 degrees,
2. When the temperature hits 100 degrees, switch to the PID soak mode and retain the temperature constantly for 15 minutes.
3. When the time is up, switch to the slope control mode, executing the condition of a 20 degree temperature rise every minute.
4. When the heating achieves 200 degrees, the hot runner control is completed.
