Word Description Bits
12 0-15 LoopĆ3 Run Temperature SetĆpoint Value Ċ Used when bit 2 of word 1 0 is on (0 thru 999.9 ).
13 0-15 LoopĆ3 Manual Output Value (CV) Ċ Used when bit 1 of word 10 is off (-100.00 thru +100.00).
14 0 LoopĆ4 Enable
• 0 = Loop 4 disabled.
• 1 = Loop 4 enabled if PID control mode selected (bits 7-8, word 2, config block).
1 LoopĆ4 Auto/Manual Mode Select
• 0 = Loop 4 is in the manual mode Ċ the manual output value (from word 17) is used as the CV value.
• 1 = Loop 4 is in the automatic mode Ċ the PID algorithm generates the CV value.
2 LoopĆ4 SetĆPoint Select
• 0 = Select the standbyĆtemperature setĆpoint value from word 15.
• 1 = Select the runĆtemperature setĆpoint value from word 16.
3 LoopĆ4 AutoĆTuning Enable
• 0 = Disable autoĆtuning.
• 1 = Enable autoĆtuning Ċ autoĆtuning can be invoked by an offĆtoĆon transition of bit 1 of word 34.
4 Always = 0.
5 LoopĆ4 PID Integral Term Reset Enable
• 0 = Accumulate PID integral term.
• 1 = Reset the PID integral term on the 0ĆtoĆ1 transition, and then allow accumulation until the next 0ĆtoĆ1 transition.
6-15 Always = 0.
15 0-15 LoopĆ4 Standby Temperature SetĆpoint Value Ċ Used when bit 2 of word 14 is off (0 thru 999.9 ).
16 0-15 LoopĆ4 Run Temperature SetĆpoint Value Ċ Used when bit 2 of word 14 is on (0 thru 999.9 ).
17 0-15 LoopĆ4 Manual Output Value (CV) Ċ Used when bit 1 of word 14 is off (-100.00 thru +100.00).
