TM 5-3895-374-24-2 EP160 ADDITIONAL MESSAGES HOLD MESSAGES DESCRIPTION The control has held for more than 10 minutes waiting for the low fire switch (M-D) to make. This message appears because of ignition cable noise.  Reroute scan- ner wires away from high voltage ignition cables.  Check for proper sparkgap.  Check for proper grounding of wiring base and power sup- ply.  Replace worn ignition cable and/or faulty connections The control has sensed an excessive current or short circuit external to terminal 5, 6 or 7.  Check for this short according to the procedure found in this bulletin on page 15 labeled "Before Installing the Con- trol." The control will lockout upon sensing this twice in a row. DESCRIPTION The "Run-Check" switch is in the Check position and will hold in- definitely.  The firing rate motor is being driven to the high purge po- sition. The "Run-Check" switch has been placed in the Check position and will hold indefinitely.  The firing rate motor is being driven to the low purge position. The "Run-Check" switch has been placed in the "Check" position during the pilot trial for ignition period.  The flame signal strength will be displayed.  The control will lockout on safety only if no flame signal is sensed for a continuous 30 seconds while the control is in this check position.  The control will not advance in the cycle until the switch is placed in the "run" position again. The "Run-Check" switch has been placed in the "Check position during the main burner on period and the firing rate motor has been driven to low fire.  The flame signal strength will be displayed as a number from 0-99 and is shown here by the symbols 00. POSSIBLE CAUSE SOLUTION -   High Electrical Noise -   Check for proper ground on power supply. -   Install noise suppressor on power supply (P/N 60-2333) -   Defective Field Wiring -   Make sure line phase on interlock circuits is the same as found on L1/L2 power supply to E100 -   Defective Amplifier -   Replace Amplifier -   Defective IR Scanner -   Replace IR Cell -   Voltage On Terminal 7 at -   Check wiring to Terminal 7 improper time.  Defective field wiring. -   Defective Chassis -   Replace Chassis (EB700) -   Defective Programmer -   Replace Programmer Note: Messages more than 8 characters in length will scroll continuously from right to left on the display.
