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).
