Reactor Error Code Trouble Shooting Guide
Rev 2.6 (02/2014) Page 5
E01: High Fluid temperature (Return to Table Of Contents)
Note: The display that is showing the E01 error is the zone that is seeing the error.
Check to see if you really do have high a temperature, by using an external
temperature-sensing device. If actual fluid temperature is above 190° F (88°C) you will
need to cool the unit down to be able to do any testing. Using your feed pumps to move
cool material into the Reactor will speed cooling time.
Causes:
1) The "A" or "B" Thermocouple (Ref # 310) picked up a high fluid temp of 229°F
(109°C) or greater.
Check connections between the temperature control module and the heater "A" & "B"
Thermocouples. Make sure all of the wires are securely connected into connector
J1/SENSOR B.
Check continuity of the "A" & "B" thermocouples by removing the J1/SENSOR B
connector from the temperature control module socket. On the plug end check the
resistance across pins 5 & 6 = 4 - 6 ohms. Pins 8 & 9 = 4 - 6 ohms. Pins 6 & 9 to
chassis ground as “OL” open loop at ambient temperature.
