Error Code # Description
20 There is no communication occurring between the Base I/O board and the processor control board. A
defective board interface cable or an unresponsive Base I/O board can cause this.
21 There is no communication occurring with the first relay expansion board. The interface cable may be
defective or the first expansion board may be unresponsive. Check the jumper configuration on the
relay expansion board to ensure that J1 and J2 are both in the “OFF” position. Verify that the values
in L090, L091, and L092 are correct for the application.
22 There is no communication occurring with the second relay expansion board. The interface cable may
be defective or the second expansion board may be unresponsive. Check the jumper configuration on
the expansion board and make sure J1 is “ON” and J2 is “OFF”. Verify that the values in L090, L091,
and L092 are correct for the application.
23 There is no communication occurring with the Steffes Time Clock Module. If this module is installed,
verify the value in L035. If correct, the interface cable or the time clock module may be defective.
24 Temperature sensor offset/reference is out of range and indicates that one of the sensors or the core
thermocouple may be shorted to ground or the processor control board may be out of calibration.
25 Power line carrier system is active; however, no good data has been received.
26 Insufficient main control board memory. Contact a qualified service technician.
27 Insufficient permanent memory. Contact a qualified service technician.
28 Permanent memory change has been made. Press the M button to accept. This error message
indicates a change has been made to the software program; therefore, it is important to verify that all
location settings are correct for the application.
29 On-board communication system is not fully operable. Contact a qualified service technician.
30 Base control board is in test mode. Check the jumper configuration on the circuit board.
31 Relay expansion board(s) are in test mode. Check the jumper configuration.
39 Indicates the value in Location 13 (L013) has been set to a value greater than the value in Location 12
(L012). The system will not charge until the value in L013 is set lower than L012.
40 Location Values are lost. The EPROM will be updated to the values saved in the main program. Clear
error by touching the M button on the heater. If this will not clear the error, replace the processor
board.
41 This error may appear when configuring the heater. Clear error by touching the M button on the
heater. If this will not clear the error, replace the processor board.
42 Internal communication error. Reprogram or replace processor circuit board.
43 An attempt to load configuration using LO 98 set to 20, 30, 40, or 50 has failed. Each location values
will need to be manually set.
Cold Core Temperature of the brick core is below 40 degrees or the core sensing thermocouple may be open.
Verify that the core thermocouple wiring is connected properly and that the values in L090, L091 and
L092 are correct for the application. If the value in L110 is reading 30, then the thermocouple is open.
Core Fail Core high limit switch may be open.
PLC Fail The system is configured for power line carrier control; however, is not receiving a valid power line
carrier communication signal.
LoAd CAP All controllable loads have been shed and Maximum Load Capacity is still exceeded.
