Important
E05: Control board over temperature
NOTE: Each module has an
1.Check that fan above electrical cabinet is operating.
2.Check that electrical cabinet door is properly installed.
3.Check for obstructions blocking cooling holes in bot- tom of electrical cabinet.
4.Clean heatsink fins behind heater control modules.
5.Ambient temperature may be too high. Allow Reac- tor to cool by moving to a cooler location.
E06: Communication cable unplugged
1.Unplug and
2.Replace communication cable if problem persists.
Communication Diagnostic Codes
E30: Momentary loss of communication
Communications between the display and the motor control board or the temperature control module have been momentarily lost. Normally, when communication is lost, the corresponding display will show E99. The corresponding control board will register E30 (The red LED will flash 30 times). If communications are recon- nected, the display can show the E30 for a small time (no more than about two seconds). It should not be pos- sible for E30 to be shown continuously, unless there is a loose connection causing the display and the board to continuously loose and regain communication.
Check all wiring between the display and the control board.
E99: Loss of communication
Communications between the display and the tempera- ture control module has been lost. When communication is lost, the display will show E99.
1.Check all wiring between the display and the tem- perature control module. Pay close attention to the wire crimping on plug J13 for temperature display and connector for control module.
Step 2 measures line voltage and should be done by a qualified electrician. If work is not performed properly it may cause electric shock or other serious injury.
2.Measure the incoming voltage to the module (it should be ~ 230Vac).
3.If it was only receiving 1 leg of the 230Vac the board may light up, and still not function properly. Correct the incoming voltage problem.
