Temperature Control Diagnostic Codes

E03: No zone current
1. Check for tripped circuit breaker inside electrical
cabinet or at power source for that zone. Replace
circuit breaker if it trips habitually.
2. Check for loose or broken connection at that zone.
3. Exchange zone module with another one. Turn
zone on and check for error (see page 38). If error
disappears, replace faulty module.
4. If E03 occurs for all zones, the contactor may not be
closing. Verify wiring from heater control to contac-
tor coil.
a.
Hose zone
: test hose continuity, page 43.
b. Perform Transformer Primary Check and
Transformer Secondary Check, starting on
page 45.
E04: Fluid Temperature Sensor
(FTS) or thermocouple
disconnected
1. Check temperature sensor connections to long
green connector (B) on temperature control module,
page 37. Unplug and re-plug sensor wires.
2. Test fluid temperature sensor continuity with ohm-
meter, 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 cor-
responding 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 Reactor
Operation manual 312062.
E05: Circuit board overheated
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.
When a no current error occurs, the LED on the
specific zone’s module turns red when the error is
displayed.

Each module has an on-board temperature sensor.
Heat is turned off if module temperature exceeds
185°F (85°C) within the heater module.
