B.5.1 Power LED (P)
This LED is located on the front panel of the pod and is lit when the system is
sufficiently powered.
The LED will turn off if the internal system voltage falls below a 4.65 (±5%)
volts, indicating a low power condition. If this occurs, power should be
removed until the cause of the low voltage is determined.
On pods with an electronic circuit breaker, the LED will blink if there is a
system fault. The rate of blinking determines the type of fault.
The system may be reset from a fault by turning off the pod and then turning it
back on. If a condition persists, please contact Microchip support.
B.5.2 Processor Module Insertion Error LED (E)
This LED will turn on when the processor module is not inserted completely or
correctly. If this LED is on, turn off the power, and remove and reinsert the
processor module.
B.5.3 Emulator Run Mode LED (R)
This LED will be on when the processor is actually running and will blink
momentarily when a single step is executed.
The function of this LED is the compliment of the Emulator Halt Mode LED
(H).
LED Condition
On System is sufficiently powered.
Off No or low power condition.
Blinking Fault detected.
Blink Rate Meaning
2 per second Overcurrent condition (more than 3 A.)
8 per second Undervoltage condition (equal to or less than
4.65V.)
3 rapid, pause, 3 rapid Undervoltage condition on processor module.
LED Condition
On Processor module not inserted completely or correctly.
Off Processor module inserted correctly.
LED Condition
On Processor is running.
Off Processor is halted.
Blink Processor executes single step.
