MPU CONTROLLER BOARD JUMPERS
There are two Controller board versions. Figure 11-2 shows an MPU Controller board with jumpers W2, W4 and
W8
. Figure 11-3 shows an MPU Controller board with jumpers W2, W4, and
W7
. These jumpers are factory set
but may need to be changed in the field. W2 and W4 are discussed in Section 11.5.5 Accessory Boards. W7 and
W8 settings are described in the figures and in Section 11.5.3 MPU Controller Board.
ETHERNET BOARD LED’s
The board has 5 green LEDs and one red LED
. Green LEDs announce status and the red LED flashes to indicate
an error code. LEDs are visible after freeing the Display Assembly and holding it slightly to one side of the case.
The LEDs are:
•
ACT - Flashes when there is Ethernet activity. It glows steadily when there is an Ethernet connection but
no activity and extinguishes when there is no Ethernet connection.
•
F/H - Lighted for Full duplex and off for Half duplex.
•
100 - Lighted for 100 MB network and off for 10 MB network
•
ST - Lighted during Self-Test and off in normal operation.
•
Modbus - When lighted, the green LED indicates an operating Modbus board. The red LED will normally
be off. When an error exists, the red LED will flash one second on/one second off with a 5 second pause.
Count the number of flashes between two pauses.
1 flash - Data bus test failure
2 flashes - Address bus test failure
3 flashes - Data read/write test failure
4 flashes - Register 40001 test failure
5 flashes - Register 40070-40077 test failure
6 flashes - Flash CRC test failure
The board is not user serviceable.
The Ethernet board’s LED power-up sequence is listed below. It is assumed that an Ethernet connection exists. The
ST and Modbus LEDs will flash in the following sequence.
1. Both Modbus LEDs and the ST LED light.
2. The red Modbus LED remains lighted while the other two extinguish. The flashing red LED during a normal
startup is not an error indication. The ACT LED will light.
3. The red Modbus and ACT LEDs extinguishes and the green Modbus and ST LEDs light.
4. The green Modbus LED remains lighted and the ST LED extinguishes.
5. The Act LED begins to flash, the F/H and 100 LEDs go to the link values, and the green Modbus LED remains
lighted.
