SSRP output is selectable one of standard ON/OFF control, cycle control, phase control by utilizing standard SSR drive
voltage output.

Auto tuning [ AT]

When setting ATparameter to ON, front temperature unit
display( or ) lamp will be flickering during Auto
tuning. After completing auto tuning, temperature
unit display lamp returns to normal operation and AT
parameter automatically becomes [ ON OFF].
Set as OFF to stop auto tuning.
It keeps previous P, I, D set values.
If SV is changed during auto tuning mode, auto tuning is
stopped.
PID time constants figured out through auto tuning function
can be changed.
If control method[ C-MD] is set to ONOF, no parameters
are displayed.
Finish auto tuning when [ OPEN] error occurs during the
operation.
In case of [ OPEN] error, auto tuning operation is not
applicable.

Input correction [ IN-B]

Input correction is to correct deviation occurred from
temperature sensor such as thermocouples, RTD etc.
lIf you check the deviation of every temperature sensor
precisely, it can measure temperature accurately.
Use this mode after measuring deviation occurred
from temperature sensor exactly. Because if measured
deviation value is not corrected, displayed temperature
may be too high or too low.
When you set the Input revise value, you may need
to record it, because it will be useful when performing
maintenance.

Input digital filter [ MAvF]

A function to filter input signals for more stable PV display
in order to provide stable control output. If noise occurs on
input signals or PV value keeps changing, it gets difficult to
perform high accuracy control since PV has a direct effect
on output level.

In case of ON / OFF control mode, even if PV reaches

to Hysteresis [ HYS] SV, loads response characteristics
or sensors location. In order to reduce hunting to a
minimum, it is required to take into following factors
consideration when designing temp. controlling;
proper Hysteresis [ HYS], heaters capacity, thermal
characteristics, sensors response and location.

Manual reset [ REST]

When selecting P/PD control mode, certain temperature
difference exists even after PV reaches stable status
because heater's rising and falling time is inconsistent due
to thermal characteristics of controlled objects, such as
heat capacity, heater capacity. This temperature difference
is called offset and manual reset [ REST] function is to set/
correct offset.
When PV and SV are equal, reset value is 50.0%. After
con-trol is stable, PV is lower than SV, reset value is
over 50.0% or PV is higher than SV, reset value is below
50.0%.

Cool / Heat function [ O-FT]

Generally there are two ways to control temperature, one
(Heat-function) is to heat when PV is getting down(Heater).
The other(Cool-function) is to cool when PV is getting
higher (Freezer).
These functions are operating oppositely when it is ON/
OFF control or proportional control. But in this case PID
time constant will be different due to PID time constant
will be decided according to control system when it is PID
control.
Cool-function [ COOL] and heat-function [ HEAT] must
be set correctly according to the application, if set as
opposite function, it may cause a fire. (If set cool-function
[ COOL] at heater, it will be maintained ON and it may
cause a fire.)
Avoid changing heat-function to cool-function or coolfunction to heat-function when the unit is operating.
It is impossible to operate both function at once in this
unit. Therefore, only one function should be selected
only.

SV High/Low limit [ L-SV / H-SV]

It sets SV high/low limit Limit range of using temperature
within temperature range for each sensor, user can set/
change set temperature(SV) within SV high limit [ H-SV]
to SV low limit [ L-SV]. ( L-SVH-SV cannot be set.)
When changing input type [ IN-T], SV high limit [ H-SV]
and SV low limit [ L-SV] of using temperature will be
initialized as max./min.value of sensor temperature
range automatically.

RUN/STOP function [ STOP]

It is allowed for users to select RUN / STOP in RUN mode.
When it is required to stop control output temporarily (e.g.,
during maintenance work), use STOP command to stop
control output.(auxiliary output is normally provided as
setting values.)
In case of STOP mode, STOP parameter and PV value is
flashing in turn on display part.
When power is off in 'STOP' mode, 'STOP' mode will be
kept after Power is supplied again. (in order to return to
normal control operation, make 'STOP' mode OFF using

If wire length of A is short, please connect mylar

SSR should be selected by the capacity of load,

otherwise, it may short-circuit and result in a fire. Indirect
heated should be used with SSR for efficient working.
Please use a cooling plate or it may cause the capability
deterioration, breakdown of SSR for a long usage.
Refer to the H-63 page for phase/cycle control connections.

Proper usage

When the load (Heater etc) is not operated
Please check operation of the OUT lamp located in front

If the OUT lamp does not operate, please check the
parameter of all programmed mode.
If lamp is operating, please check the output(Relay, SSR
drive voltage) after separating output line from the unit.

This is a warning that external sensor is open.
Please turn off the power and check the wire state of the
sensor. If sensor is not open disconnect sensor line from
the unit and short the input +, - terminal. Turn on the
power of the unit and check the controller displays room
temperature.
If this unit cannot display room temperature, this unit is
broken. Please remove this unit and contact our service
center. (When the input mode is thermocouple, it is
available to display room temperature.)

Caution for using

The connection wire of this unit should be separated from
the power line and high voltage line in order to prevent
from inductive noise.
For crimp terminal, select following shaped terminal (M3)

Max. 5.8mm

Please install power switch or circuit-breaker in order to

cut power supply off.
The switch or circuit-breaker should be installed near by
users.
This unit is designed for temperature controlling only. Do
not apply this unit as a voltage meter or a current meter.
In case of using RTD sensor, 3-wire type must be used.
If you need to extend the line, 3-wires must be used
with the same thickness as the line. It might cause
temperature difference if the resistance of line is different.
In case of making power line and input signal line close,
line filter for noise protection should be installed at power
line and input signal line should be shielded.
Keep away from the high frequency instruments.(High

When supplying measured input, if HHHH or LLLL is
displayed, measured input may have problem. Turn off
the power and check the line.
