E05: Control board over
temperature
NOTE: Each module has an on-board temperature sen-
sor. Heat is turned off if module temperature exceeds
185°F (85°C) within the heater module.
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 re-plug cable that connects heater con-
trol module to heater module.
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.
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.
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.
