JohnPeters Posted: Mar 04, 2009 07:17 AM	E-30 with EO1 errors!!! All, So my Graco E-30 has been plagued with EO1 errors for the last few months. We typically see 3-5 EO1 errors for every 8 hour shift. We reset the heater or recycle power to the proportioner with the error pops and press on. I purchased a brand new temp control board and installed it yesterday. I am still seeing the EO1 errors - in fact now we are getting EO4's. Does anyone have any ideas? JP

I thought that somehow it converted from temperature to amps on the readout and it turned out I had cut a wire on one of the connections. Not sure what E 01 is, but I certainly know what an E-24 is.

IF YOUR UNIT HAS MODULES SIMPLE SWITCH MODS. TO DETERMINE IF MOD. IS BAD. E04 IS FTS OR THERMOCOUPLE IS DISCONNECTED. AGAIN,ALOT OF THE TIMES THIS IS A CONNECTION PROBLEM NOT A BOARD. DISCONNECT LONG GREEN CONNECTOR,CLEAN AND REINSTALL. ALOT OF TIMES E01 & E04 OCCUR BECAUSE THE TERMINAL IS DIRTY AND NOT CONNECTING. CHECK TERMINALS FIRST BEFORE REPLACING BOARDS OR MODS.

E-30 with EO1 errors!!!

All,

So my Graco E-30 has been plagued with EO1 errors for the last few months. We typically see 3-5 EO1 errors for every 8 hour shift. We reset the heater or recycle power to the proportioner with the error pops and press on.

I purchased a brand new temp control board and installed it yesterday. I am still seeing the EO1 errors - in fact now we are getting EO4's.

Does anyone have any ideas?
