4.1.2.9 Position lock

There are three position locks: "SET", "LOCAL", "REMOTE" on the panel of the controller for Type KST-2H.

4.1.2.10 Programming interf

ace function

The controller provides programming interface to communicate with programmer. Users can set internal

parameters by programmer, such as: choose type of overload protection characteristic curve, turn on or turn

o thermal memory function, set signal contact output function, choose communication protocol function,

set communication address, choose communication baud rate, set system clock

, set function lock and unlock,

choose connection mode of voltage etc. The programmer also has break/close test function, historical data

review function, set value copy and other functions.

The telecommunication of the controller stops automatically when the programmer connected to the

interface, after the programmer pull out, the telecommunication resumes automatically.

Apply for "ST programmer op

erating instruction" to get more information.

4.1.2.11 Analogy calculation function of main contact rate of wear

The controller can simulated calculate the main contact wear rate according to the fault current and other

data when breaking. The factory-set is 100%; it shows no wear on the main contact. After each breaking

operation, the controller will deduct corresponding wear rate, when the value

≤ 60%, system will set alarm

the self-diagnose signal to inform users taking the maintenance action in time.

After replacing the main contact, users can reset the initial wear rate as 100% by programmer or other special

ways.

4.1.2.12 Historical data recording (optional)

The controller can note various historical data of the power grid every 30 minutes, includes date, time,

current, voltage, power,

frequency, power factor, kilowatt-hour, lasting 3 months. Via programmer interface

or telecommunication interface, the relative data review software. In the computer can be read out the

information.
