Type
INPUT TYPE
: Selects the input sensor type to be connected to the
controller.
Default:
1
(T/C Type K)
“This is the first parameter to be set.”
0
- T/C type J: -58 to 1400°F ( -50 to 760°C )
1

2
- T/C type S: 32 to 3200°F ( 0 to 1760°C )
3
- RTD-Pt100 with 0.1°
resolution: -199.9 to 986.0°F ( - 199.9 to 530.0°C )
4
- RTD-Pt100 with 1°
resolution: -328 to 986°F ( -200 to 530°C )
5

8
- T/C type R: 32 to 3200°F ( 0 to 1760°C )
NOTE:
In case of sensor break or failure an error " Erro
" message
is displayed, and the control output is turned off.
Vnit
TEMPERATURE UNIT:
Selects display indication for degrees
Celsius or Fahrenheit.
Default:
0
0 - degrees Celsius (
°(
);
1
- degrees Fahrenheit (
°f
);
A(t
ACTION CONTROL: Default:
0
0
-
Reverse action
. Generally used for heating.
1
-
Direct action
. Generally used for cooling.
(ntr
CONTROL OUTPUT CONFIGURATION:
0
- Sets
Control output
(ON/OFF or PWM - PID) on terminals
13-15 (4-20mA pulsed), with
Alarm-1
on terminals 11-12, and
Alarm-2
on terminals 9-10. See
atvn
and
pb
for ON/OFF and
PID control description in Cycle-2, page 12.
Note:
4-20mA will operate as PWM in the 4mA or 20mA state,
(This is not a linear 4-20mA output control in this configuration).
1
- Sets
Control output
(ON/OFF or PWM - PID) on terminals 11-12,
and
Alarm-2
on terminals 9-10
.
2 - Sets
Linear 4-20mA PID Control output
on terminals 13-15,
with
Alarm-1
on terminals 11-12, and
Alarm-2
on terminals 9-10.
NOTE
: •
Controller model TC33-1100-AC:
Default =

SpLl
SETPOINT LOW LIMIT:
Sets the lower range for SV and PV
indication.
Default:
-150
Spxl
SETPOINT HIGH LIMIT:
Sets the upper range for SV and PV
indication.
Default:
1370
Atvn
AUTO-TUNE
: Activates the auto-tuning of PID parameters.
0
- Auto-tune is off (led “AT” = off)
When set to
0
the controller is in Manual PID control or ON/OFF
control
(pb = 0 ).
1
- Auto-tune is on (led “AT” = on)
When set to 1
the controller is in PID Auto-tune control.
Default:
0
Pb
PROPORTIONAL BAND
: 0 to 500% of maximum input span.
When this parameter is set to zero
(Pb= 0 )
and
atvn
is set to
0
the
control action is
ON/OFF
output mode, with control hysteresis adjust.
Default:
10.0
Ir
INTEGRAL RATE
: 0.00 to 25.00 rep/min = Integral time constant in
repetitions per minute (Reset).
Default:
0.00
This constant is not used when controller is set to ON/OFF action
(Pb= 0 ).
Dt
DERIVATIVE TIME
: 0 to 250 = Derivative time constant in seconds.
This constant is not used when controller is set to ON/OFF action
(Pb= 0 ).
Default:
0
(t
CYCLE TIME
: Pulses in period per second. This term is only used when
the controller is set to PID action
.
Default:
0.5 (in seconds)
KySt
CONTROL HYSTERESIS
: Is the hysteresis for ON/OFF control (set in
temperature units).
Default:
0
This parameter is only used when the controller is in ON/OFF mode
(Pb= 0 ).
A1SP
SETPOINT value for ALARM 1
: Set-point for alarm 1
Default:
610
A2SP
SETPOINT value for ALARM 2
: Set-point for alarm 2
Default:
610
