Resumen del manual


This kit is provided with a step by step field service bulletin FSB10033.doc 8-10 Convection Circuit CONVECTION (BLOWER) MOTOR OPERATION The convection (blower) motor is a variable speed convection motor, which operates from zero rpm up to 7000 rpm. The blower motor speed is controlled by a SP200 AC/Delta drive control. The speed of the motor is directly proportional to the applied low voltage to the SP200 AC./Delta drive control from the control circuit card. The blower motor operates during warm up cycle, the normal idle operation (for stabilization of the oven temperatures) and also while in the cooking mode at a set desired speed. Additionally, during the Test mode, which allows the technician to manually operate the blower ON and OFF to change the speed (0% to 100%). HOW TO TURN THE BLOWER ON 1) Press the BACK key until displaying say OVEN OFF. 2) From the OVEN OFF screen Press the BACK & ENTER keys simultaneously and key in Pin # 9-4-2-8 then ENTER. Older units Pin# 8-3-1-7 3) Press the BLOWER key to increase air speed from 0-100%. Each time the key is pressed and increment of 10% will occur on the air speed. 4) Verify status indicator "A" at the bottom of the screen is not highlighted. P – S –M– t –h –H – A –W 5) Verify that the blower motor rotates freely and does not vibrate from imbalance. 6) Verify that the blower shaft rotates in the counter-clockwise (CCW) direction when viewing the shaft from the right side of unit. 7) While in the TEST mode, Open the cook door and ramp the blower speed from 10-100% and verify air pressure is present from the top of the cooking chamber. If oven is cold then place your hand inside cooking chamber and as you ramp the blower air a substantial difference should be noted. Checking input voltage at motor controller 1) Place Oven in Test Mode. 2) Press BLOWER Key and Measure Voltage (DC) between Pin 7 (SP-200) or Pin AVI (Delta) and ground.

C Series Blower Circuit Defective Messages SELF TEST WHILE COOKING CAUSE CORRECTIVE ACTION BLOWER STATUS BLOWER STATUS Blower motor speed 1) Verify jumper on P3 of control or "F1 BLOWER" or "F1BLOWER" controller not returning the "running status command" See status indicator A board is present and placed according to motor controller (see wiring diagram section for details). Note: If the door is opening intermittently, the blower will cease to operate. Pins 1&2=Reliance Controller Pins 2&3=Delta Controller 2) Check Auxillary fuses (refer to schematic 3) Verify incoming voltage is present on controller input (200-240VAC). 4) Verify status indicator A is not highlighted. (See Page 5-3) 5) Check controller output voltage on motor controller (see Table 8-1) 6) Check fault messages on blower motor speed controller (refer to appropriate controller selection). 7) Check all connections in the blower circuit (ribbon cables, signal wires). 8) Check all interlock switches. 9) Verify motor shaft turns freely, if not then remove motor assembly and inspect wheel. 8-9 Convection Circuit Blower Motor Controller Fault Codes & Troubleshooting NOTE: If no fault condition exists, the LED will be green. If a fault condition exists, the LED will flash redhen a local keypad is not connected. All faults can be reset by cycling the reset control input, pressing the stop key, or cycling power, except as noted in the Corrective Action column below. NOTE: To recycle power, disconnect power for a full minute, or until the LED extinguishes, before reapplying power. Reliance Blower Motor Controller Fault Codes & Troubleshooting # of LED Flashes Fault Description Fault Cause Corrective Action 2 Control Input · Illegal control input sequence · 3–wire: Verify Start and Jog inputs are not both ON · 2–wire: Verify that only one input (Forward, Reverse, or Jog) is ON 2 Function Loss · Start attempt while STOP (function loss) input is off · Verify STOP (function loss) input is ON before attempting to start drive. 3 Under Voltage · Low input line · Temporary loss of input line · Check input line to verify voltage is within operating specifications 4 Over Voltage · High input line · Decel time too fast · Overhauling load · Check input line to verify voltage is within operating specifications · Increase decel time 5 Drive Overload · Excessive driven load · Reduce the load 5 Motor Overload · Excessive driven load · Verify P-02 is set correctly · Reduce the load. · Check for mechanical binding 6 Over Temperature · Operating environment is too hot · Verify the ambient temperature is <50.C · Fan is b...
