32 XR Series Installation and Technical Instructions

Start-Up

5.1 Power Up

• The XR has no ON/OFF button or switch. Plugging the unit into AC

power will turn the unit ON.

• Disconnecting AC power will turn the unit OFF.

5.2 Reset Button

• The RESET button (marked as RST on the XR 2000) on the controller

board allows the technician to cycle power on the unit without

disconnecting/connecting AC power.

5.3 Auto-Learn

• On power up, the XR automatically enters Auto-Learn mode, analyzing

the serial communications and string type.

• The indicator’s output string must contain number characters. Also, an

STX character (ASCII 02) must precede all other characters and/or the

string must end with <CR> character. CR is ASCII 13. See example

below:

• Once Auto-Learn is successful (about 10 seconds after power up) the

XR will display the current weight.

5.4 LEARN Button

Automatic Start-up Auto-Learn may

be disabled for custom

applications. See Switch 6: Start-

up Auto-Learn on page 36.

• If Automatic Start-up Auto-Learn is disabled, the LEARN button

(marked as LRN on the XR 2000) on the Controller board must be

pressed to enter Auto-Learn mode.
