EATON XT series stabilizing pump control box

3. Overload protection setting

The setting value of the overload relay should be consistent with the full load current on the motor nameplate. The setting value of the circuit breaker is set according to the label inside the cabinet.

4. Run time timer (optional)

The timer panel is equipped with three rotating dials that can set the running time. The default function is "Single Trigger" (Ws), which means that the control signal is triggered and runs for a set time. During this period, it can be triggered multiple times, but the next cycle can only be started after the complete running cycle.

Digital Display Screen and Programming

The XT series controller comes standard with a digital display screen, which displays system pressure, start pressure, and stop pressure in real-time. The display screen is NEMA 4X protection level, with four red LED highlights, supporting pressure unit switching and alarm indication.

Programming steps (using factory default values as an example):

Enter programming: Press and hold the PGM key to display 'run'.

Input type setting: Press the ↑ key to display "inp", press the → key to select "4.20" (4-20mA input).

Decimal point setting: Press the ↑ key to display "dp" and "1000", no need to modify.

Offset setting: Press the ↑ key to display "OF" and "+0000", no need to modify.

Full range setting: Press the ↑ key to display "FS" and "+0500", no modification required.

Relay 1 high alarm: Press the ↑ key to display "1Hi" and "+9999", no modification required.

Relay 1 low alarm (starting pressure): Press the ↑ key to display "1Lo" and "+0000", press the → key to move the cursor, and use the ↑↓ keys to set the starting pressure value (such as "+0100" displayed at 100psi).

Relay 2 high alarm: Press the ↑ key to display "2Hi" and "+9999", no modification required.

Relay 2 low alarm: Press the ↑ key to display "2Lo" and "-9999", no modification required.

Return difference setting: Press the ↑ key to display "HYS" and "+0000", press the → key to move the cursor, and use the ↑↓ keys to set the return difference value (such as stopping the pressure at 115psi and setting the return difference to+0015).

Exit programming: Press the ↑ key to display "run" and return to the pressure display interface.
