Temperature Control Diagnostic Codes
3A1570V 13
E04: Fluid Temperature Sensor
(FTS) or thermocouple
disconnected
1. Check temperature sensor connections to long
green connector (B) on temperature control module.
See Temperature Control Module, page 29.
Unplug and re-plug sensor wires.
2. Test fluid temperature sensor continuity with
ohmmeter. See E01: High fluid temperature, page
11.
3. If an error occurred for the hose zone, check FTS
connections at each section of hose (see page 34).
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 manual current control mode. Refer to Reactor
Operation manual.
E05: Control board over
temperature
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.
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
reconnected, the display can show the E30 for a small
time (no more than about two seconds). It should not be
possible 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.
