CUSTOMER DISPLAYS

Customer Display Interface
Symptoms: The Integrated or Pole Customer Display does not function. The unit should auto-detect the LCD customer display or IEE 2x20 VFD customer display at power-up. If a customer display is not detected after several power-up cycles, you can check the following.
• Internal customer display cable disconnected from J2 or IO panel
connector damaged.
• Damaged Pole Customer Display Connector CN3.
• No Power to Customer Display Connector.
o Make sure +5V appears at J2-1. If not, check voltage switch Q9, Q8
and F6.

VFD Pole Customer Display - Blinking Character but no Information Displayed

Symptoms: All segments of the upper left character blink continuously while the
WS4 LX boots. When Windows Embedded CE 6 starts and loads the WS4 LX
API, it sends an initialization command to the display to turn off the blinking
character. If the character continues to blink after the operating system starts,
check the following:
• Defective Remote Customer Display Cable
• Defective Customer Display

VFD Pole Customer Display - Blank or Characters very dim

Symptoms: No characters appear on the VFD. The upper left character does not
blink at power-up.
• Check fuse F1 on the WS4 LX system board. If very hot, check for a shorted
or defective pole display interface cable.
• Defective VFD Interface Board. Check the following:
• Defective CR9 (+12V Zener Diode) or Q1 (MMBT2222A)
• Blank display but +5V OK. (F1 on WS4 system board is not hot), bad U6.
• Blank display but F1 is hot - bad U1 or U2 display anode drivers
