• How to tune. Make an impulse on the 8-9 terminals. The controller tunes the parameters at the SP.
If the overshot may damage the process limit the output (Y) in 1.p/3.level/Yd’ and set 1.p/EPid[2]=1.
Let ALARM3 1.p/A3d[****3210]=****1010 and let the value of 1.p/1.level/A3 a little higher than the expect-
able biggest overshot.
There are two tuning method for motorized valve control. If 1.p/3.level/Yt<15 the tuning do not use the
travel time. If the controller uses the travel time written in1.p/3.level/Yt>15 1.p/3.level/Yt.

Warranty
Model: KD48P
Serial number: Date of purchase: Validation by the supplier:
The cost of transport (out and home) is borne by the customer. .
The HAGA Automation LTD’s KD48 series warranted to be free of defects in material, and fabrication. The warranty is valid
for 3 years after delivery to the first purchaser for use. The second period of the warranty is 2 years long in which the
manufacturer repairs the defective controller without fee, except the cost of materials. .
Since the HAGA Automation LTD can not influence the usage of the controllers, so the warranty is not valid for the
damages cased by them in the connected devices. ..
. .
The HAGA Automation LTD examines in its electrical laboratory the defective controller and detects the cause of breakdown.
The warranty does not apply to damage resulting from transportation, alteration, misuse or abuse. .
EMC installation guidelines
The KD48P controller generally is not sensible for electrical noise. The controller does not disturb the other instruments in
its environment as well. The extreme circumstances such as long leads, inductances without filters, etc. may reduce the
control qualities. In such cases you ought to prevent the spreading of the electric noise. The noises must be eliminated the
closest to its source. The filters and snubbers at the controller's inputs and outputs generally have not enough effects.
There are some thumb rules for improving the control properties. .
Connect to the every inductive coil a special filter as close as possible.
Give power from the operating circuit in a cabinet. If there is not, use separating transformer.
In very noisy environment install the controller in metal case which is properly connected to protective earth. If you have
more protective net use the best by trial. .
In very extreme environment (inductive heating, radio transmitter, X-ray appliances etc.) call an expert.
CAUTION: In any critical application where failure could cause expensive product loss or endanger personal safety, a
redundant limit controller or monitor is required. We recommend the KD48Bx controller. .
Never run the signal and control cables together the AC power lines. Use shielded cables and connect the shields (pigtails)
to the PE. .
All these sensible cables run as far the noise sources as possible.

For automatic lead compensation
Cascade control
KD48P PID Profile Controller. User’s Manual.
The KD48P type profile controller can solve all of your
heating tasks, where the temperature must be
controlled precisely by the time. .
Due to the robust PID algorithm the KD48P controls
the temperature along the programmed profile with
minimal oscillation. .
Please configure the controller before starting up. It is
necessary to read up this manual. Some skill in
knowledge of control may be useful. .
Danger warnings
Programming
It is very easy programming a profile by the graph.
Press the delayed START green lamp blinks and
the time appears in form on the display.
You can decrease with or inrease with
the delay.
Save the value pressing the again. The lamp of the 1. RAMP (heating velocity) will blink in form .
After pressing the controller saves the previous value and steps to the SOAK temperature setting.
The green lamp blinks and value displayed in form .
Set the SOAK temperature with .
Caution! The point at the and is the
signal of SOAK temperature.
Press and repeat the setting process for the SOAK time .
The time units of START delay, RAMP and SOAK are in hour or in minute according to configuration 1.p/dPrG[6].
Continue the programming to the and of the profile in the same way. The graph shows you what to do.
keys decrease or increase the displayed value with one unit at a press, but will run down or up
accelerated for holding them down. After the last program step the controller exits from programming. .
Press and hold for 5 seconds to start the control. The display changes from OFF to On. The controller
runs the programmed profile to the command or to the profile end. You can stop the program pressingEnd
and hold for 5 seconds. The lamps light red and the actual blinks. So the graph demonstrates the state
of process. .
The Difference display shows the control deviation. You can inquire about the actual time or temperature
pressing .
The lamp from among which is set blinks green. The actual running program step lamp is red and blinks.
The lamps of executed steps are continuously red. The lamp which is set in state blinks red-green.On .
For making the handling clear we name the profile construction and the set of the properties
of controller . To program a profile go through the graph and write the values in display and save.
Some useful facilities can you find below:

When you enter a RAMP in the graph appears. At his command the program jumps across the
velocity segment and heat without any restrictions to the next temperature.SOAK
The temperature limits are configured in 1.p/3.level/ and .SOAK SPlo SPHi
Step one before with there is the which finishes the profile, turns out the controller.FrEE
At SOAK time value the controller jumps to the next RAMP, so it is possible to use two RAMPS
continuously. SOAK time is guaranteed so there is an automatic FrEE before SOAK temperature. This may
disabled by 1.p/3.level/con[6]=1.
The SOAK time may be timeless if 1.p/3.level/dLin[4]=1. The display shows in such a case .
The programming may be enabled or disabled by the 1.p/3.level/out[7] and 1.p/3.level/dPrG[5] in or
state. In state the controller acts by the changed value immediately..
On
OFF On
All of the ALARM (4 pc) can work as event in each program segment. Configure the properties in the places:
the properties first in 1p./3.level/A*d and A23L, the values after it in 1.p/1.level/A* and A*h.
Using the ON-OFF mode the system oscillates, the PV swings around the SP. The PID control mode gives
the efficiency performance. The H-TUNE determines the parameters after starting. Enter the set point
in the place of first soak temperature by this sketch. Configure 1.p/3.level/out[54]=00. Give a
short circuit on 8 9 terminals for 1-3 seconds. The display shows holding down . The controller
makes 3 on-off oscillations around the selected set point and writes the parameters in the 1.p/1.level. After
it returns to the normal mode. The PID parameters can be altered for modifying of control properties.
tunE
.
Operation of H-TUNE function
The auto tune may be started in or state. The controller goes state finishing the tune.
For special tune see foot-note on 1. page.
On OFF OFF
.
There is a modulated (intermittent signal on the 2. relay if) 1.p/A23L[7]=1 and on the 3. relay if A23L[3]=1
when the relay is active. Acknowledge and turn off the signal with pressing .
There is a buzzer instead of relay by order.
In the controller containing 16 program steps
you may change by pressing for 5
seconds. The profil names are:
profiles
and .P-- I P--II
The controller containing 56 program steps you
profile inmay choose a 1.p/1.level/PrFL.
The Fig.2. shows an annealing program. The
explanations are as follows:
The range of the first part of the program is
effective to the line 7. The next part runs to
the line 13 and the symbol is lighting. At
the line 11 the controller turns off the process.
+
If two profile is connected 1.p/3.level/dPrG[2]=1
during the running of the second profile the II
symbol is lighting. .
Take it into account that the profiles may be connected by the 1.p/3.level/dPrG[012]= configuration. Write
the connected programs by itself in OFF state. The editing of connected programs in On state are disable.
***
Cation! If there is a START delay before a connected program than it appears before each profile, but it
will be effective after the start only. .

The ALARMs are a logical functions which act the relays. In the 1.p/3.level/A*d defined properties
determine the value of this function in the process. If the result is 0 the relay inactive (default state).
If it is 1 than active (reverse to the default). The relay is open in the case of reverse
configuration in active state. Some bool functions are in 1.p/3.level/A23L. These functions can connect
ALARMs together e.g.: in case of A23L[210]=100 R3 is active if AL3 AL4 are active.
Caution!

When the heat source is far from the workpiece, the controller can not regulate it properly. The controlI
is slow and unstable. Such process is the heating in a retort. Because of the big delay time a fair-sized
temperature overshot may occur.
To eliminate the the waste in material and energy, use 2 controllers in one cascade group. The inside
controller will be the MASTER and the outside the SLAVE.
The HAGA controllers are able to control in cascade method. You can configure the MASTER and connect
to the SLAVE thorough the communication port.

Configuring
The configuration specifies the properties of the controller. The configuration pages accept the data by
the model identification only. There is a map on the 1. page containing all of the menu items and the
moving possibilities among them. There are a lot of security items in the menu. The adequate
configuration helps you to select a very good operation. Using the security code to the necessary grade
the handling will be very easy. So the operator can not enter false data into the process. .
Press and hold and after it for about 3 seconds. The blinking appears. This is the first level of
configuration (see map on 1.page). Browse about the menu items with . At menu item you
can go on the second level and at menu item on the third level.

Addition to the KD48P Manual
The addition can be found in the 3. page at the d.FrE menu item.
This supplement contains some useful properties..
The light intensity can be set from half to whole. The half intensity is enough in normal circumstances and the instrument does not
warm over. The whole intensity has to use by daylight.
The band of switching from ramp to Soak may be widened. When the PID parameters are not precisely tuned or the power is very few
then the controller can not reach the Soak temperature and it is switching some degrees under it. This option eliminates the
phenomena, but would be better to use a correct PID parameter set.

1 The actuator can be scaled at YLo and YHi for Solid State Relay Driver (Ssd).
Settings of the actuator.Ifd.FrE[0]=0 the actuator operates by the Manual. If d.FrE [0]=1 and out[1]=0 (using relay or, Ssd for the
control) the actuator (Y) can be alterable and scalable. The relation between the Yvalue counted by the PID algorithm and value
which appears at the output is the next:
Y=0% the output is (e.g. Ssd) YLo.
Y=100% the output is (e.g. Ssd) YLHi. But YLo <YHi relation must be true!
YLo and YHi are set by the Manual and are the endpoints of the actuator scaling..
The controller counts the value for actuator between these two values linearly.
What is this function for? In some system occurs that its power is to much. This option can improve the control properties.
E.g. set YHi=50. By this value the actuator gets 50% when the counted value is 100%. It seems if the power had been halved. The
system has changed of course so it must be tuned again.
Important! Please tune the system after every actuator scaling!
Pay attention to the value of YLo! Because of the lowest value of the YLo is the least value for the actuator, it will operate
the system eve it is in OFF state. Be careful when use it! It my be useful for saving a system against frost.
