Temperature Control Diagnostic Codes

E04: Fluid Temperature Sensor
(FTS) or thermocouple
disconnected
1. Check temperature sensor connections to long
green connector (B) on temperature control module,
page 34. Unplug and re-plug sensor wires.
2. Test fluid temperature sensor continuity with
ohmmeter. See E01: High fluid temperature, page
8.
3. If an error occurred for the hose zone, check FTS
connections at each section of hose.
4. If an error occurred for the hose zone, test FTS by
plugging directly into machine.
5. To verify heater control module is not causing the
problem, use a wire to short-circuit the two pins
corresponding to the FTS (red and yellow for A or B
zone, red and purple for hose). The display will
show the control heater module temperature.
6. If an error occurred for the hose zone, temporarily
use the current control mode. Refer to your Reactor
Operation manual.
E05: Circuit board overheated
NOTE: Each module has an on-board temperature
sensor. 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
bottom of electrical cabinet.
4. Clean heatsink fins behind heater control modules.
5. Ambient temperature may be too high. Allow
Reactor to cool by moving to a cooler location.
E06: Communication cable
unplugged
1. Unplug and re-plug cable that connects heater
control module to heater module.
2. Replace communication cable if problem persists.
