Debugging and settings
Overview of parameter settings
The initial state of the controller after power-on is defined as "General state". The state of entering the menu operation and
setting parameters is defined as “Setting state”.
Corresponding menus set the parameters of the controller, and each parameter has a corresponding menu. There are a few
additional menus that perform specific functions.
Setting parameters: press “Enter” in “General state” to enter the setting state if the password is 0. Otherwise, “Password” will
display, input correct password to enter the setting state.
Selecting menus: press “Shift” (flip up) or “Change” (flip down) to change between menu items.
Entering or exiting the menus: press “Enter” once.
Modifying parameters: press “Enter” to enter the menu; the lowest bit of the parameter value will be negative displayed,
press “Change” to modify the value on the bit. The value on the negative displayed bit will add one with each press of
“Change”. When it adds up to 9, the bit will automatically become 0. When the lowest bit is modified, press “Shift” once, the
nearest next bit will be negative displayed. Modify the value in the same way by pressing “Shift” and “Change” alternately to
complete all the modification.
Saving and exiting the menu: Execute the “Ok” menu
The functions of each menu are described below.
Setting the damping
Corresponding menu: Damping
The damping setting is used to stabilize the sampled signal and allow smoother data display. The damping setting range is
0.0~100.0s. Damping will increase the response time. It should be set reasonably according to the working conditions.
Temperature switch control parameters: KtA, KtB, KtDelay and KtType
Corresponding menus: Kt-A, Kt-B, Kt-Delay and Kt-Type
Parameters KtA and KtB can be combined to form 3 control schemes as follows:
1. With differential control: KtA<KtB, switch acts when the measured value > KtB, switch resets when the measured value is
< KtA.
2. No differential control: KtA=KtB, switch acts when the measured value > KtB, switch resets when the measured value <
KtA.
3. Window control: KtA> KtB, switch acts when KtB < measured value < KtA, otherwise switch resets.
Parameter KtDelay is used for switching action delay with a setting range of 0.0~100.0 seconds. This parameter is equally
effective for switching action and switching reset. Parameter KtType is used to set the switch contact type: 0 represents
normally open type and 1 for normally close type.
