What to do if Woodward ProTech 203 Protection Device prime mover overspeeds after operating at rated speed?
If the prime mover overspeeds after running at its rated speed for a while, check the prime-mover fuel system for proper operation. If the actuator moves toward minimum fuel during the overspeed, the problem lies within the fuel system itself.
What to do if Woodward ProTech 203 prime mover won't start?
If the prime mover doesn't start, consider these potential causes and solutions: * Check the power supply fuses, wiring, and power sources if one or more de-energize to trip units lack power. * Press the RESET key if one or more ProTech units need to be reset. * Verify the type of ProTech model to ensure a de-energized-to-trip model isn't installed when an energized-to-trip model is appropriate, or vice versa. * Check the actuating system for proper normally open or normally closed wiring if the actuating wiring from the ProTech device is incorrect.
What to do if Woodward ProTech 203 Protection Device prime mover does not trip on overspeed?
If the prime mover fails to trip on overspeed, here are some things to check: * Apply power to all ProTech units if power is not applied to an energized-to-trip ProTech model. * Check that the ProTech device is installed properly, in case it is not connected or is incorrectly connected to the external actuating system. * Check the MPU GEAR TEETH and TRIP SPEED SETPOINT configurations for each unit to verify that they are appropriate for the prime mover and the individual MPUs if incorrect set point values are configured for one or more units. * Check for incorrect field wiring and inoperable or incorrectly calibrated actuating equipment if two or more units show a TRIPPED indication, as the cause may be the external actuating system down-line from the ProTech device.
What to do if Woodward ProTech 203 Protection Device unit is not operating and STATUS 1 & 2 and TRIPPED are illuminated?
If the unit is not operating and the STATUS 1 & 2 and TRIPPED indicators are lit, press the RESET key to reset the unit.
What to do if Woodward Protection Device prime mover trips inappropriately?
If the prime mover trips inappropriately, consider these solutions: * If more than one unit has been overspeed tested at one time, reset the units. * If incorrect set point values are configured for one or more units, check the MPU GEAR TEETH and TRIP SPEED SETPOINT configurations for each unit to verify they are appropriate for the prime mover and the individual MPUs.
What to do if Woodward Protection Device has neither LCD nor LED display?
If the unit shows no display on either the LCD or LEDs: * Check that power is applied to the unit, as the unit may have no power. * Consider replacing the unit's power supply board fuse. * It is possible that the power supply board is faulty.
What to do if Woodward ProTech 203 Protection Device trips inappropriately during start-up?
If the unit experiences an inappropriate trip during start-up, consider the following: * If the contact input is not used, jumper together TB5-14 and TB5-15 of each unit, in case the contact input was left open and the TIMER STARTS ON RESET option is set to "Yes". * Verify that the MPU FAIL SETPOINT and MPU FAIL TIMEOUT are appropriate for the prime mover, in case the prime mover is not ramping to the configured speed in the allotted time, due to incorrect set point values configured for one or more units. * Check that all MPUs are correctly wired to the ProTech device and are functioning properly, in case of an incorrect MPU signal.
What to do if Woodward ProTech 203 has LCD display, but no LEDs display—or vice versa?
If the unit has an LCD display but no LEDs, or vice versa, the unit is faulty.
What to do if Woodward ProTech 203 Protection Device won't RESET?
If the unit won't RESET, check that the remote RESET operates as a momentary contact, as the remote RESET contacts may be closed.
What to do if Woodward ProTech 203 annunciates inappropriate trip due to hardware fault?
If the unit annunciates an inappropriate trip due to a hardware fault because the EEPROM doesn't respond correctly, reset the unit.
