Installation Instructions
Keyboard keys:
"SET": Menu editing or right shift of numerical value (in digital input state);
<—Move up or increase the value of the menu item;
—>Move down or decrease the value of the menu item;
—>Move down or decrease the value of the menu item;
<—|Back to the upper menu, back and save the settings during parameter setting.
Note
1. In the input state of CT value and PT value, the "SET" key is the key to move the cursor to the right. AC current CT value: CT= primary current value of current transformer/secondary current value of current transformer
DC current CT value:
CT=shunt primary current value/5 (signal input DC75mV)
CT=display value/1 (signal input DC 20mA, DC 4-20mA)
AC voltage PT value:
PT=Primary voltage value of voltage transformer/Secondary voltage value of voltage transformer
DC voltage PT value: PT=display value/input value
2. Indicator light:
"K": thousand units, the real value is one-thousand times the displayed value.
