Word Description Bits
14 0 LoopĆ5 Enable
• 0 = Loop 5 disabled.
• 1 = Loop 5 enabled.
1 LoopĆ5 Auto/Manual Mode Select Ċ (controlled by bit 1 of word 18 of the dynamic block)
• 0 = Loop 5 is in the manual mode Ċ the manual output value (from word 21, dynamic block) is used as the CV value.
• 1 = Loop 5 is in the automatic mode Ċ the PID algorithm generates the CV value.
2 LoopĆ5 Open Circuit
• 0 = LoopĆ5 thermocouple circuit is closed (connection OK).
• 1 = .LoopĆ5 thermocouple circuit is open (connection broken).
3 LoopĆ5 Parameters valid
• 0 = Power has been interrupted since valid parameters for loop 5 have been blockĆtransferred.
• 1 = Valid parameters for loop 5 have been blockĆtransferred since last loss of power .
4 LoopĆ5 Calibration Fault
• 0 = LoopĆ5 calibration is OK.
• 1 = LoopĆ5 cannot operate with as calibrated.
5 LoopĆ5 SetĆPoint Select Ċ (controlled by bit 2 of word 18 of the dynamic block)
• 0 = Select the standbyĆtemperature setĆpoint value from word 19 of the dynamic block.
• 1 = Select the runĆtemperature setĆpoint value from word 20 of the dynamic block.
6 LoopĆ5 Parameter Value Error
• 0 = LoopĆ5 parameter values OK.
• 1 = LoopĆ5 parameter value error.
7 LoopĆ5 AutoĆTuning Complete
• 0 = LoopĆ5 autoĆtuning is not complete.
• 1 = LoopĆ5 autoĆtuning is complete.
8 Reserved.
9 Reserved.
10 LoopĆ5 Thermal Runaway Ċ (set in words 22 and 23 of the configuration block)
• 0 = LoopĆ5 is operating within thermal runaway limit..
• 1 = LoopĆ5 has exceeded the thermal runaway limit. and the CV value has been forced..
11 LoopĆ5 High CV Limit Ċ (set in word 7 of the configuration block)
• 0 = LoopĆ5 CV value is below the high CV limit.
• 1 = LoopĆ5 CV value is at the high CV limit.
12 LoopĆ5 Low CV Limit Ċ (set in word 8 of the configuration block)
• 0 = LoopĆ5 CV value is above the low CV limit.
• 1 = LoopĆ5 CV value is at the low CV limit.
