Word Description Bits
2 13 LoopĆ1 CV Ramp Rate Ċ (selected in bit 4 of word 3 of the configuration block)
• 0 = LoopĆ1 CV is not ramping.
• 1 = LoopĆ1 CV is ramping at the rate entered in word 4 of the configuration block.
14 LoopĆ1 Input High TC Range Alarm Ċ (based on thermocouple type set in bits 12-15 of word 2 of the configuration block)
• 0 = LoopĆ1 PV input is below the high TCĆrange alarm value.
• 1 = LoopĆ1 PV input is at or above the high TCĆrange alarm value.
15 LoopĆ1 Input Low TCĆRange Alarm Ċ (based on thermocouple type set in bits 12-15 of word 2 of the configuration block)
• 0 = LoopĆ1 PV input is above the low TCĆrange alarm value.
• 1 = LoopĆ1 PV input is at or below the low TCĆrange alarm value.
3 0-15 LoopĆ1 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 1.
• 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).
4 0-15 LoopĆ1 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 1.
• 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.
