1.Dual output :
It needs installing hardware then enter level 4 (set level) and set “OUTY. 1st& 2nddigit” 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
2 ℃ 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
& 4thdigit” 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.

e. If next segment’s “OUT” set to “0”, the program will end at this segment. If the program needs repeat, it has to
enter level 4 and set “PROG. 4th digit” to “1”.
f . Function key for program:
In the intial window status, pushing ”up” key for 4 sec., the program start and “pro” LED flickers, pushing
“down” key for 4 sec., the program pause and “PRO” LED keeps light.
If pushing “UP” key first then pushing key again, the program will jump to next segment, but if pushing
“down” key first then pushing key again, the program will end immediately and “PRO” LED is “off”.
g. Alarm function for program:
1).Segment ending alarm
“AL1/AL2/AL3” & “ALD1/ALD2/ALD3” in level 3 must be set.
example: Set “ALD1” to “07”
Set “AL1” to “2”, the alarm function will perform in segment 2
Set “ALT1” to “00.20 M/S.” the alarm will perform 20 sec., 00.20 H/M. the alarm will perform 20 MIN If set
it to “0” the alarm is in flicker but if set it to “99.59” the alarm is in continuance.
2).Program ending alarm:
“ALD1/ALD2/ALD3” in level 3 must be set.
example: Set “ALD2” to “17”, if the “PROG. 1
st
digit in level 4” set “1”, the alarm2 will perform when the program
end, but if the “PROG. 1
st
digit” set “0”, the alarm2 will perform during program process then it stops
when the program end.
h. Other functions:
1).Power failure function:
If the “PROG. 1
st
digit” set “1”, it has power failure function the program will perform again from stopped
segment when the power is recovered. On the contrary, if the “PROG. 1
st
digit ” set “0”, it hasn’t power failure
function, the program always perform again from first segment when the power is recovered.
2).When the program start from first segment, if “the PROG. 2
nd
digit” set “1”, it will start according to “PV” but if
the “PROG. 2
nd
digit” set “0”, it will start according to “0”, if it is set to start from PV, the controller will check PV
& SV-1 which is small if PV is small it will start from PV but if SV-1 is small it will start from SV-1.
3).Wait function:
If the “WAIT” parameter in level3 set “0”, it has not wait function, but if it sets other volume the SV will wait the
PV when the PV exceed the SV over the set volume.
4.Remote SV function:
a. It needs modifying hardware (contact the distributor)
b. Set the “MODE. 1
st
digit” to “1” and the “MODE. 4th& 3rddigit” to “11” in level 4.
5.Master and slaver function:
a. Both master and slaver need installing TTL communication hardware.
b. The master unit must be with program function, then setting its “TIM2. 4
th
& 3rd” to “11” and “FUNC. 1
st
digit” to “1” in level4. in addition to set “IDNO” parameter to “0” and “BAUD” parameter with ideal volume in level3.
c. The slaver unit must be without program function, then setting “TIM2. 4
th
& 3rddigit” to “11”, “FUNC. 2nddigit” to
“1” “MODE. 4
th
& 3rddigit” to “11” and “MODE. 1stdigit” to “0” in level4 in addition to set among
“ALD1/ALD2/ALD3” to “0” in level3. In this case one among “AL1/AL2/AL3” will convert to “RATE” function.
SET
SET
P.8
d. The “RATE” parameter is for setting how many percentage of SV in Slaver unit according with master unit. For
example, if the master SV is “1000” then we set “RATE” to “90” in slaver, the SV of slaver will be “900”.
e. One set of alarm can be used for “RATE” only.
6.Ramp and Soak function:
It doesn’t need installing hardware but has to modify software as following steps.
a. Set “MODE. 4
th
& 3rddigit” to “10” in level4.
b. For ramp function , it needs setting one among “ALD1/ALD2/ALD3” to “9” then one among “AL1/AL2/AL3” will
convert to “ramp” function. Setting unit for “RAMP” is “xx.xx
℃/MIN.”, and the PV will raise according to setting
volume until it finishes.
c. For soak function, it needs setting “MODE. 1
st
digit” to “0” for H/M or “1” for M/S, and one among “ALD1/ALD2
/ALD3” must be set to “19”, then one among “AL1/AL2/AL3” will convert to “soak” function and a time can be set
among “AL1/AL2/AL3”. When the PV reach the SV, it starts time counting, in the meantime one among “AL1/AL2
/AL3” and time will display alternately. When the time reach setting volume, the alarm perform and the control
output stop.
d. One set of alarm can be used for ramp and one set of alarm can be used for soak only.
7.Motor valve control function:
a. It needs installing hardware. (contact the distributor).
b. Set “MODE. 1
st
digit” to “1” in level4 to open second input.
c. Set “OUTY. 4
th
& 3rddigit” to “01” in level4 to open motor valve control function.
d. Set “CYT1” to open/close cycle time of motor valve in level2 and “RUCY” to time from open to close of motor valve
in level3.
e. The LED bar on the panel will display the position of motor valve.
f . Second input is for feedback use, it has 4~20mA,0~10mA,0~10VDC,2~10VDC,0~5VDC,1~5VDC or potentiometer.
8.SCR control output (resistance load only):
a. It needs installing hardware (contact the distributor).
b. Set “TIM2. 4
th
and 3rddigit” to “01” in level4 to open PWM output function.
c. Set “OUTY. 4
th
and 3rddigit” to “10” in level4 to open single phase function or “11” to open three phase function.
9.Analogue output function:
a. It needs modifying hardware, there are 4~20mA, 0~20mA, 0~5VDC, 0~10VDC, 1~5VDC, 2~10VDC. (contact
the distributor).
b. Set “CLO1” to lowest limit in level3. For exam ple, if lowest output is 4mA, then set it to “400”.
c. Set “CHO1” to highest limit in level3. For example, if highest output is 20mA, then set it to “2000”.
d. Set “TIM2. 4
th
and 3rddigit” to “01” in level4 to open PWM function. (Relay & SSR Output set “00”)
e. Set “OUTY. 4
th
and 3rddigit” to “00” in level4.
10.Analogue input (Input 1 only):
a. It needs modifying hardware, there are 0~10mA,4~20mA,0~1VDC,0~5VDC,0~10VDC (contact the distributor).
b. Set “INP 1” to “AN1~4” in level3, and set “LSPL” to lowest range, “USPL” to highest range in level3.
c. Set “LCK” to “0111” in level 2.
d. Push key and key for 4 sec. until “INPL” is displayed on upper window.
e. Send input signal for lowest range until display is stable, then push key to enter.

f . Send input signal for highest range when upper window displays “INPH”.
g. Push key when “INPH” is stable.
11.Transmitter output:
a. It needs installing hardware (contact the distributor).
b. Set “TIM2. 4
th
and 3rddigit” to “10” in level4 to open transmitter function.
c. Set “TIM2. 2
nd
digit” to “0” in level4 for PV transmitter or to “1” for SV transmitter.
d. Set “OPRL” to lowest range and “OPRH” to highest range in level3.
12.Communication function:
a. It needs installing hardware (contact the distributor).
b. Set “FUNC. 1

c. Set “TIM2. 4
th

d. Set “IDNO” parameter to address and “BAUD” parameter to ideal volume in level3.
e. Refer to communication protocol.
13. Auto/manual switch function:
a. It doesn’t need installing hardware.
b. Push key for 4 sec. under auto status, it converts to manual control function. In this case, the “MAN” LED
light and the volume of output will be controlled by “OUTL” which can be adjusted with or key to increase
or decrease. For example, set “OUTL” to “50”, the output volume always keep 50% until “OUTL” is changed.
c. Push key for 4 sec. under manual status, it converts to auto control function.
d. MC-2438 series don’t have this function.
