Digital Fault Menu Loop

Caution: The Digital Fault Label selection must agree with the external control wiring prior to
energizing the controller. Failure to do so may cause severe equipment damage.

Allows a fault to be either an Alarm fault or a Shutdown fault.
Note: Any activated alarm or shutdown fault will energize the "Common fail" fault and sound the alarm horn.
If an fault was set as an Alarm, it may be selected as a "Latching" alarm or "Non-latching" alarm. A Latching alarm is not
cleared until a reset command clears it.
Note: This value only appears if alarm faults are programmed. Shutdown faults are automatically set as latching.
Allows the digital fault circuit to be set for Open to Fail or Close to Fail sensing contacts.
Allows the alarm or shutdown fault to be disabled until after the bypass timer has expired. Faults that are not delayed are
enabled at all times (i.e. engine running or stopped).
Allows the selected fault to be disabled until the delay period has expired. Delay times are 0.0 to 999.9 seconds.

The corresponding digital output must also be programmed for IDLE to enable correct operation.
The No Load Test digital input feature is typically used in an AMF application where it is required to do an automatic
timed No Load Test of the engine/generator set. A contact from an external exercise clock timer is required to be
connected to the digital input circuit which is programmed for "No Load Test". When a digital input is programmed as No
Load Test, these settings must be programmed to ensure correct operation:
Action Alarm
Alarm Latch No
Polarity Close Or Open (dependent on external circuit used)

Displays the generator phase voltages to be calibrated.
Displays the type of calibration function, either ZERO or SPAN.
Displays the calibration correction factor number (0-255) used to obtain the correct voltage reading.
Note: To correctly calibrate any of the voltage sensors, the ZERO function must be calibrated before the SPAN function.
Displays the actual voltage measurement that will be the same value as shown on the MEC 2 display menus for
generator supply. This voltage reading may be calibrated higher or lower by changing the correction factor number.
Zero Calibration must be completed before Span Calibration.
Connect an external AC voltmeter of adequate voltage range and accuracy to the MEC 2 controller terminals associated
with the voltage phases to be calibrated. With the generator stopped, confirm there is Zero volts on the phases to be
calibrated. In the programming mode, scroll to each of the desired generator supply voltage phases (i.e. phase to phase
or phase to neutral) with the ZERO function selected. Use the INCREMENT or DECREMENT push-buttons to adjust the
correction factor number to obtain zero volts on the right hand side of the display as confirmed with the external
voltmeter. The factory default correction factor is 127. Increasing this will raise the displayed value, conversely
decreasing this value will decrease the displayed value. Note: Adjusting the ZERO function with voltage applied will result
in non-linear voltage readings.
With the correct voltage displayed, press the ENTER push-button to accept the correction factor number. Record the
correction factor number on the programming sheet for future reference. Repeat this procedure for all remaining phases.
