5 INTRODUCTION AD-310 MACHINE OPERA TIONAL SUMMAR Y The model AD-310 incorporates one (1) “ EMERGENCY STOP (E-Stop) BUTTON ” located centrally on the Right Front Control Door . This " RED " MUSHROOM PUSH-BUTT ON is “ PUSH TO STOP ” the machine and “ TURN TO RELEASE ” or “ PULL TO RELEASE ” type control device.
6 EMERGENCY (E-S top) ST OP BUTT ON (Push T o Stop/T urn T o Release or Pull T o Release) This " red " mushroom push-button, located in the center of the Right Front Control Door almost directly under the Phase 5 Microprocessor Controller (computer) is a “Push T o Stop” and “T urn T o Release” type push- button.
7 CONTROL POWER (Off) This " RED LIGHTED OPERA TOR ," located on the Right Front Control Door , is for disabling the dryer ’ s output control voltage.
8 AD-310 MACHINE OPERA TION TROUBLESHOOTING INFORMA TION END OF CYCLE/HEA TER F AUL T INDICA T OR The “END OF CYCLE” light located on the top/front of the dryer , is triggered by the Air Jet Signal of the Phase 5 Microprocessor Controller (computer) to the input of the PLC (Programmable Logic Controller).
9 2. Check to see that the Air Jet L.E.D. (light emitting diode) is on at the end of the drying cycle. If the L.E.D. is not on it may be an indication of a failed Phase 5 Microprocessor Controller (computer). 3. If Air Jet L.E.D. is on then check the wiring from the Phase 5 Microprocessor Controller (computer) to the air valve.
10 2. Check that 80 PSI of compressed air is supplied to the machine and that the “Front Up” solenoid is being actuated by the PLC (Programmable Logic Controller). Refer to the PLC (Programmable Logic Controller) signal information included in the ladder diagrams and schematics supplied with the machine.
11 When a “HEA TER F AUL T” occurs after the first twenty-five (25) seconds of the drying cycle, a “CLEAR/ STOP” will be sent to the Phase 5 Microprocessor Controller (computer), a “FILL” .
12 The L.P . (liquid propane) gas pressure measured at each gas valve pressure tap must be 1 1-inches water column (W .C.) pressure, when the flame is established in both burner boxes. There is no means to adjust this pressure supplied with the dryer so the downstream L.
13 ONE (1) BURNER WILL NOT IGNITE A T THE BEGINNING OF A CYCLE This condition can be caused by the following: • DEFECTIVE DSI (Direct Spark Ignition) MODULE • DEFECTIVE SP ARK IGNITOR/FLAME-PROBE .
14 The dryer system is divided into a number of “electrical” sections which are as follows: 1. Right Front Control Panel The RIGHT FRONT CONTROL P ANEL is located in the Right Front Control Cabinet of the dryer . This panel is the heart of the drying system, where ALL control signals interface to or from this panel.
15 4. Optional Sprinkler Circuit The OPTIONAL SPRINKLER CIRCUIT main control panel will be located in the left front electrical enclosure. If a SPRINKLER OPTION is included with the dryer , this panel will include an “AUTOMA TIC EMERGENCY STOP” feature.

28 B. ELECTRICAL REQUIREMENTS and GAS REQUIREMENTS It is your responsibility to have ALL electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms with local and state regulations or codes.
29 SECTION V COMPONENT DESCRIPTION/REPLACEMENT A. HEA T SECTION The AD-310 dryer uses three (3) types of heat sources: natural gas, liquid propane (L.P .) gas, and steam. Natural Gas and L.P . (liquid propane) gas are not directly replaceable. The gas valves need to be modified to use other than the type of heat specified on the nameplate.
30 a . The Direct Spark Ignition (DSI) Module is a 24 V AC device designed to be the "controller" of the DSI system. When activated by the dryer controls, this module constantly monitors and controls the functions of the DSI system (i.e., spark activation, gas valve off and on, flame verification, etc.
31 e . The T umbler Hi-Limit Switch is a thermostat type switch located above the Lint Basket. Its function is to discontinue heat (flame) in the event of an over temperature situation (above 225º F).

37 First Visual Check (Does Ignitor Spark?) I s spark evident (on) at Ignitor Assembly? Is 24 Volts present across DSI Module terminals TH and COM? Check High Voltage (HV) Lead for nicks or cracking, where sparking to ground may occur. Is this wire damaged? Go To Chart 2 Open circuit to DSI System.
38 e . T roubleshooting Flow Chart - Quick Reference... Second Visual Check (Does Main Burner Ignite?) Does main burner light? Is manual knob on the Gas Valve in the "ON" position? Is dryer .
39 f . T roubleshooting Flow Chart - Quick Reference... Third Visual Check (Does Main Burner Ignite?) Does main burner remain lit? Does the Flame Probe have carbon or dust build up? Reposition Flame Sensor Probe to achieve a 2µa or greater sensor current or, if unattainable, replace the Sensor Probe Assembly.
40 3. T roubleshooting and System Detailed Diagnosis When the dryer calls for heat, 24 V AC from the step down transformer is applied to the "TH" and "GND" terminals of the DSI (Direct Spark Ignition) module.
