  • Page 11 Integrated ( 2) Series Integrated ( 2) Series 700- Electronic Control 700- SECTION 3 ELECTRONIC CONTROL SYSTEM INFORMATION NOTE: The Electronic Control System used in an Integrated (700-2) Tall Unit differs from the Electronic Control System used in a Integrated (700-2) Base Unit. For this reason, Section 3 is divided into two parts.
  • Page 12 700- ELECTRONIC CONTROL TERMINOLOGY & COMPONENT DESCRIPTIONS All Integrated 700-2 Series units utilize an electronic control system. The electronic control system monitors, regu- lates and controls a variety of functions. The electronic control system also displays temperature readings, ice maker system operation, possible problems with the unit and door ajar alarm status. The table below defines some basic electronic control system terminology and describes some of the electronic control system components.
  • Page 13 Integrated ( 2) Series Integrated ( 2) Series 700- Electronic Control 700- BASIC 700- 2 TALL UNIT ELECTRONIC CONTROL SYSTEM Input operations for the electronic control system are performed at the control panel (located at the top of the upper compartment), with monitoring, regulating and controlling functions taking place at the control board (located directly behind the control panel).
  • Page 14 Integrated ( 2) Series Integrated ( 2) Series Electronic Control 700- 700- 700-2 TALL UNIT CONTROL BOARD LAYOUT AND SUMMARY TABLE The electrical connection points on the 700-2 tall unit control board are labeled alphanumerically. These labels cor- respond with the alphanumeric control board summary table, located on all 700 Series wiring diagrams. By refer- encing the summary table, it is possible to identify which components are connected at which connection points on the control board.
  • Page 15 Unit ON/OFF All Integrated 700-2 Series units are shipped in the OFF Mode and when power is supplied to the unit, a trace of the word “OFF” is visible on the LCD. By pressing and releasing the UNIT ON/OFF key, (See Figure 3-5.)
  • Page 16 Door Ajar Alarm Bell ON/OFF All Integrated 700-2 Series units are equipped with a door ajar alarm feature. When activated the alarm will alert a customer if a door or drawer is left or stuck open. To enable the door ajar alarm feature, press and release the door ajar alarm bell ON/OFF key on the control panel.
  • Page 17 Integrated ( 2) Series Integrated ( 2) Series 700- Electronic Control 700- FUNCTIONS OF 700 TALL UNIT ELECTRONIC CONTROL SYSTEM The following few pages explain the monitoring, regulating and controlling functions of the electronic control system. Signal trace schematic illustrations for the model 700TC/I-2 are used to demonstrate current flow for the function being explained.

Though the com- partment air temperature does fluctuate, the LCD displays the average temperature (See Figure 3-10).
  • Page 19 Integrated ( 2) Series Integrated ( 2) Series 700- Electronic Control 700- Control Variable Speed Compressor (700TF/I-2V) Like other tall units, the temperature signal from the thermistor in a 700TF/I-2V freezer compartment is monitored by the microprocessor and then displayed on the LCD, and when cooling is called for, the evaporator fan and condens- er fan are energized.
  • Page 20 Integrated ( 2) Series Integrated ( 2) Series Electronic Control 700- 700- Control Condenser Fan Run The microprocessor senses the 115 volt output supplied to both compressors. If either compressor is running, a sig- nal is sent to the condenser fan relay on the control board to close, supplying power to the condenser fan. If both compressors are off, the condenser fan is off.
  • Page 21 Integrated ( 2) Series Integrated ( 2) Series 700- Electronic Control 700- Monitor Compressor Run Duration, Displays If Service may be Needed (700TC/I-2, 700TR-2 and 700TF/I-2) The microprocessor in the models 700TC/I-2, 700TR-2 and 700TF/I-2 senses the 115 volt output supplied to the compressor(s), monitoring the length of compressor run time (See Figure 3-15).
  • Page 22 Integrated ( 2) Series Integrated ( 2) Series Electronic Control 700- 700- Monitor and Control “Adaptive Defrost” of Freezer Evaporator Initially the freezer compressor will cycle-run for twelve hours (twenty-four hours in model 700TF/I-2V), after which the microprocessor sends the signal to the defrost relay on the control board to close. This supplies power to the defrost heater, and the compressor is switched off (See Figure 3-15).
