Page 64 Troubleshooting the MVP system can be relatively simple. First the MVP must be powered-up. This requires only a power and ground connection to the MVP. Next the EDC needs to be powered-up and communicating with the MVP. Power and ground are supplied to the EDC on two wires and the EDC communicates with the MVP on two RS422 wires.
Page 65 Symptom: Symptom: Symptom: “REF” is displayed for the digital value for all temperature functions. Symptom: Symptom: 1. Problem: The Middle Connector on the EDC is loose or not connected. The Reference Diode on pins 10 and 28 of the EDC Middle Connector is damaged. Note: Pin 28 should measure 0 volts and pin 10 should measure around .6 volts.
Page 66: Rpm Problem
Symptom: Symptom: Symptom: Inaccurate, jumpy or zero readings on all channels. Symptom: Symptom: 1. Problem: The Reference Diode on pins 10 and 28 of the EDC Middle Connector is damaged. a) Action: Measure the voltage on the Reference Diode. Pin 28 = 0 volts and pin 10 = approx. 0.6 volts.
Page 67: Fuel Flow Problem
Symptom: Symptom: Symptom: Inaccurate, jumpy or zero reading. Symptom: Symptom: 1. Problem: An Isolator was NOT used between the EDC RPM channel and the P-lead at the back of the Mag Switch. The signal on the P-lead is hundreds of volts and this could damage the RPM input to the EDC.
Page 68: Amp Problem
1. Problem: The rotor in the Fuel Flow Transducer is blocked. a) Action: Remove the Flow Transducer from the aircraft. Lightly blow into the transducer and check for the rotor to spin freely. Check for a Fuel Flow reading on the MVP when the rotor is spinning.
Page 69: Capacitive Fuel Level Problem
7.9 Capacitive Fuel Level Problem: Fuel can be measured in a fuel tank using a Capacitive Fuel Probe. The Electronics International P-300 Ca- pacitive Fuel Probe connects to an IMC (Interface Module) located near the probe, and to the EDC through three wires.
Page 70: Voltage Problem
Symptom: Symptom: Symptom: An “Err Err” is displayed for the digital value. Also, you may have an inaccurate, jumpy or zero Symptom: Symptom: reading. 1. Problem: The IMC is mis-wired. a) Action: Measure the voltage on the three wires at the IMC Module (Red wire = +5 volts, Black wire = ground, White wire = +2.5 volts).
Page 71 a) Action: Check that the voltage on the appropriate EDC pin changes from high to low and back to high as the Annunciator is cycled. 2. Problem: The MVP is set up incorrectly. a) Action: Check the "Start" and "End" setting in the “4. Redlines, Limits and Color Setup” screen.

Page 96 A3.0 Appendix LASAR Ignition RPM Filter Rev: New 5/2/07 The LPF-1 is a low-pass filter designed to remove the high frequency spikes on the LASAR Ignition RPM output. Without this filter the RPM readings on the MVP unit may display jumpy readings at various engine RPMs.
Page 97 A4.0 Appendix Connecting an EDC Input to a Custom Probe There are five steps to connecting a Custom Probe to an EDC Input, associating it with a Function and displaying that Function on the MVP. 1. Connecting a Custom Probe to an EDC Input: The EDC Temperature, Pressure and Fuel Level Inputs can be interfaced to almost any type of probe.
Page 98 EDC Capacitive Fuel Level Input: Type: Frequency Input Freq. Range: 0 to 6K Hz. Resolution: Approx. 14 counts per Hz. Maximum Counts Available: Approx 98,000 Trigger Level: 2.1 Volts Input impedance: 33.2K Ohms 2. Assign a Function to the EDC Input: A Function must be assigned to the EDC input connected to the Custom Probe.
Page 99 5. Assign Color Ranges and Limits to the Selected Function: You may set color ranges and limits for the selected Function. The "4. Redlines, Limits and Color Setup" screen provides the necessary parameters. Navigating to the “4. Redlines, Limits and Color Setup” screen. Start with the “Main Engine“screen and push the MENU button.
