1.Dual output :

It needs installing hardware then enter level 4 (set level) and set “OUTY. 1

st

& 2

nd

digit” to “11”. Output 1 is for heating

and output 2 is for cooling in the meantime. If it needs a gap, DB1 is for setting.

2.Loop broken alarm (loop short or loop open alarm):

It doesn’t need installing hardware but has to modify software as following steps.

a. Set “ALD1/ALD2/ALD3” to “18” in level 3 and enter level 4 to set “FUNC. 3

rd

digit” to “1”

b. Open “’AL1/AL2/AL3” in level 3 and set high/low/ alarm value.

c. Open “TOH, TSH” in level 3 and set the time of loop short and loop open.

Principal:

When PV is lower 2 

than low alarm set value within TSH time or PV is higher 

than high alarm set value      

within TSH time, it is loop short.

When PV is higher than high alarm set value, but it doesn’t drop 0.5 

in TOH time or PV is lower than low alarm 

set value but it doesn’t raise 0.5 

in TOH time, it is loop open.

3.Program:

It doesn’t need installing hardware but has to modify software as following steps.

a. Open “MODE” in level 4 and set “mode. 3

rd

& 4

th

digit” to “01” then the parameter of process will be displayed in 

window.

b. Change “LCK” to “0100” then it can set program parameter. The program has 2 patterns, each pattern contains 8

segments. 2 patterns can be linked together to 16 segments.

c. The “PTN” parameter set to “1”, it will display first section of 8 segments. The “PTN” parameter set to “2” it will 

display second section of 8 segments. If “PTN” is changed to “0” after setting PTN1 & PTN2, the program will be 

linked together to 16 segments.

d. Each segment can be arranged as ramp or soak; ramp is for changing SV with time while soak is for keeping SV

with time.
