4.4 Status LED (D1)

The EN5004-xx communications module pc board (A12) features a Status LED (D1) built
into the board, located to the left of the Configuration Switches (S1). See Figure 2 on page 5
for location. During normal operations the LED will flash very quickly to indicate
communications with the host computer. Use the following guide for LED troubleshooting:
4.4.1 Blinking LED
On power up the D1 will blink on and off at a steady rate of 1 sec. on and 1 sec. off to indicate that the
Modbus Address selected by the DIP switches S2 is invalid. The acceptable Modbus address range is 1-
247. For example, if all the switches for S2 are set to off for an address of 0, the LED will blink for an
invalid address.
4.4.2 LED Always Off
The LED will flash when the communications board receives and processes data from a host computer.
When the LED does not flash, then the communications board is not processing the data being sent to it by
the computer. Check the following items to al items can be the cause of no communications.
•
Verify that the connection P13 is aligned properly with J13 on the main control card.
•
Make sure the power supply connection J20 is plugged in.
•
Measure the voltage of J20 pins 2(+) and 4(-) with J20 plugged in. It should be between 7-10vdc.
•
Check the communications wiring from the host computer to the communications board.
•
If the communications board is wired for RS-232 make sure RS-232 is selected in the DIP switches.
•
If the communications board is wired for RS-485 make sure RS-485 is selected in the DIP switches.
•
Check all the communication configuration settings.
•
Verify the host computer's communications settings match the charger communications board settings
(protocol, address, baud rate, stop bits, data bits, etc.).
4.4.2 LED Always On
If the LED is always on then this indicates the communications board is not working. Check the
following:
•
Verify that the connection P13 is aligned properly with J13 on the main control card.
•
Make sure the power supply connection J20 is plugged in.
•
Measure the voltage of J20 pins 2(+) and 4(-) with J20 plugged in. It should be between 7-10vdc.
