Temperature Control Diagnostic Codes

12 312066ZAF

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 40). 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

contactor coil.

a. Hose zone: test hose continuity, page 45.

b. Perform Transformer Primary Check and

Transformer Secondary Check, starting on

page 47.

NOTE: When a no current error occurs, the LED on the

specific zone’s module turns red when the error is

displayed.

E04: Fluid Temperature Sensor

(FTS) or thermocouple

disconnected

1. Check temperature sensor connections to long

green connector (B) on temperature control module,

page 39. Unplug and re-plug sensor wires.

2. Test fluid temperature sensor continuity with

ohmmeter, page 10.

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 Reactor

Operation manual 312062.

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.
