4.4Display Module
•The Display Module contains a microprocessor whose function is to take the inputs from the front panel and send the appropriate command to the Motor Controller Module. It also controls the output to the display LEDs and beeper.
•Test the Display LEDs. Power on at the wall. This illuminates all LEDs for 2 seconds. Check the operation of all the switches and check the appropriate LED lights.
•If not all LEDs illuminate check that the LEDs are not bent. Open up housing, (with power off) and reposition the LED.
•Replace if there is any sign of corrosion on the Display Module. This is one of the most likely causes in older Smartdrives.
•The display has up to 4 hidden modes where the function of the buttons is different. Option adjustment mode, Diagnostic mode, Size Setting mode and Demonstration mode.
•On Phase 1 and early Phase 2 the Display Module was fitted with the lid switch. Check it activates correctly onto the plastic ‘button’ in the console.
•Phase
•Phase
•3 different display modules, LW, MW and GW. The AW is fitted with an LW display.
•Phase
•Colour of the display identifies the phase. Blue (or white) is Phase 1 and 2. Green is Phase 3. Yellow is Phase 4 and grey is Phase 5. The phase and colour of the display must match that of the Motor Controller.
•Phase 1 (spare). See WM011 in Appendix B.
•Pressure sensor and EEPROM on Phase 1 is in display, (not phase 1 spare).
•Condensation kit may be fitted to phase
