If the microcontroller determines that the EEPROM is not responding correctly, a

trip occurs. The trip cause is annunciated as a hardware fault. If this type of fault

occurs, reset the unit. If the fault continues to occur, replace the unit and return it for repair.

If the microcontroller determines that the data in EEPROM has been corrupted,

the display shows "eeprom data lost". If this type of fault occurs, reset the unit. If

the fault continues to occur, replace the unit and return it for repair.

The microcontroller monitors an interlock signal which indicates that the internal

hardware cables are connected correctly. If this signal indicates a missing

interlock, a trip occurs. The cause of the trip is annunciated as an interlock fault.

If this fault occurs, check all cable connections.

If a monitor circuit determines that the microcontroller is not functioning, a trip

occurs. The CPU FAIL LED turns on. If this fault occurs, replace the unit and

return it for repair.

The overspeed test function is activated when the key switch is in the

PROGRAM position and the operator presses and holds the OVSP TEST button

on the touch pad. The microcontroller switches the source of the MPU signal

from the MPU input to an on-board oscillator. The test speed is annunciated on

the LCD. If the test speed is adjusted above the trip setpoint, using the Test

Frequency potentiometer on each unit, a trip occurs. MPU loss-of-signal

checking is disabled, and the peak speed value does not change during

overspeed test. When the OVSP TEST button is released, the microcontroller

switches the source of the MPU signal back to MPU input and normal operation

is restored. Each ProTech unit must be reset to clear its trip condition.
