5.3.1 Checking LEDs
ControlWave modules contain light emitting diodes (LEDs) that provide
operational and diagnostic functions.
Table 5-1 shows LED assignments on modules.
Table 5-1. LED Assignments on Modules
Module /
Board
LED Name LED Color Function and Location
PSSM MC Red Master Clear; ON 2msec after PWR FAIL goes
low. See Figure 5-10.
PSSM PWRFAIL Red ON = Bulk or regulated power out of
specification. See Figure 5-10.
PSSM PWRGOOD Green ON = Normal operation; all power supplies
okay. See Figure 5-10.
CPU CR1 – WATCHDOG Red ON = Watchdog condition. See Section 2.3.5
for a description of what causes a watchdog.
See Figure 5-11.
CPU CR2 – IDLE Red ON = CPU idle. The CPU should show idle
most of the time. If this light goes OFF and
stays OFF, the CPU is overloaded. See Figure
5-11.
CPU CR3 – COMM 1 RX Red ON = RX (receive activity) on COMM1. See
top-left of LED cluster in Figure 5-11.
CPU CR3 – COMM 1 TX Red ON = TX (transmit activity) on COMM1. See
top-right of LED cluster in Figure 5-11.
CPU CR3 – COMM 2 RX Red ON = RX (receive activity) on COMM2. See
bottom-left of LED cluster in Figure 5-11.
CPU CR3 – COMM 2 TX Red ON = TX (transmit activity) on COMM2. See
bottom-right of LED cluster in Figure 5-11.
CPU CR8 – ENET Port 1 Red/Green ON RED = Data Collision (Left – see Figure 5-
11.)
CPU CR8 – ENET Port 1 Red/Green ON GREEN = Receiving data (Left – see
Figure 5-11.)
CPU CR8 – ENET Port 1 Red/Green ON RED = Transmitting data (Right – see
Figure 5-11.)
CPU CR8 – ENET Port 1 Red/Green ON GREEN = Link O.K. (Right – see Figure 5-
11.)
SCB CR2 – COMM 3 RX Red ON = RX (receive activity) on COMM3. See
top-left of LED cluster in Figure 5-11.
SCB CR2 – COMM 3 TX Red ON = TX (transmit activity) on COMM3. See
top-right of LED cluster in Figure 5-11.
SCB CR2 – COMM 4 RX Red ON = RX (receive activity) on COMM4. See
bottom-left of LED cluster in Figure 5-11.
SCB CR2 – COMM 4 TX Red ON = TX (transmit activity) on COMM4. See
bottom-right of LED cluster in Figure 5-11.
