7.12 Logic Switches
A logic switch is a virtual switch connected to 2 physical switches which activates or deactivates according to a
mathematical relationship between the two.
Example: Logic switch,"and"gate. If only switch one or switch 2 is active, the logic switch will remain off, however if
switches 1 and 2 are active at the same time, then the lotic switch will activate.
A logic switch can be used in any function that can assign switches.
It is used to set the ratio between brake application time and
brake release time. The adjustment range is -4 to +4 duty cycles.
The default value is 0. When the value changes, the peak and
trough length of the brake pulse square wave will be changed.
Adjust the ratio of brake to release:
•
The ratio is 1:1 when the cycle is set to "0";
•
The ratio is 1:2 when the cycle is set to "1";
•
The ratio is 2:1 when the cycle is set to "-1".

Steps:
1. Click the icon at the bottom of the interface to enable this function;
2. Click to select the option you want to set;
3. Click on "+" or "-" to change the setting value;
4. Repeat the above steps to set as needed;
5. Carry out a test to ensure that settings are completed as expected.
Steps:
1. Select a logic switch.
2. Touch the top Select Sw, then select a switch and
position.
3. Touch the bottom Select Sw, then select a switch
and position.
• The logic switch will not function without 2
physical switches assigned.
4. Select a logic gate, [ AND], [OR] or [XOR] as needed
• Refer to the table below for more information
on logic gates and their function.
5. Toggle the switches to make sure everything is
working as expected.

Function Settings:
There are 3 logic switches.
[Select Sw.]: Touch here to select a switch from the switch selection menu.
[AND]: If switches 1 and 2 are active, then the logic switch will be on.
[OR]: If switches 1 or 2 are active, or switches 1 and 2 are both on, the logic switch will be on.
[XOR]: If switches 1 or 2 are active, then the logic switch will be on, but if switches 1 and 2 are both active the logic
switch will be off.
[Switch1]: Displays the status of switch 1.
[Switch2]:Displays the status of switch 2.
[Logic switch1]:Shows the status of logic switch.
