LoopĆ3 CV Ramp Rate Ċ (selected in bit 4 of word 3 of the configuration block)
•
0 = LoopĆ3 CV is not ramping.
•
1 = LoopĆ3 CV is ramping at the rate entered in word 4 of the configuration block.
14
LoopĆ3 Input High TC Range Alarm Ċ (based on thermocouple type set in bits 12-15 of word 2 of the configuration block)
•
0 = LoopĆ3 PV input is below the high TCĆrange alarm value.
•
1 = LoopĆ3 PV input is at or above the high TCĆrange alarm value.
15
LoopĆ3 Input Low TCĆRange Alarm Ċ (based on thermocouple type set in bits 12-15 of word 2 of the configuration block)
•
0 = LoopĆ3 PV input is above the low TCĆrange alarm value.
•
1 = LoopĆ3 PV input is at or below the low TCĆrange alarm value.

LoopĆ3 ConfigurationĆBlockĆError or GainsĆBlockĆError Word Ċ Indicates the first configurationĆblock or gainsĆblock word
containing an outĆofĆrange value or incompatible bit selection. (See appendix B for details on locating errors.)
•
0 = No error detected in configuration block or gains block for loop 3.
•
1 thru 23 in the leastĆsignificant pair of digits = configurationĆblock error Ċ (lowerĆdigits value = word containing error).
•
1 thru 57 in the upper pair of digits = gainsĆblock error Ċ (upperĆdigits value = word containing an outĆofĆrange value).

0-15
LoopĆ3 DynamicĆBlockĆError Word or AutoĆTuning Error Code Ċ Indicates the first dynamicĆblock word containing an
outĆofĆrange value or an autoĆtuning error. (See appendix B for details on locating errors.)
•
0 = No error detected in dynamic block or in autoĆtuning for loop 3.
•
1 thru 34 in leastĆsignificant pair of digits = dynamicĆblock error Ċ (lowerĆdigits value = word containing outĆofĆrange value).
•
65 thru 67 in the upper pair of digits = a code that indicates an autoĆtuning error.
