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.

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.
.

Programming
It is very easy programming a profile by the graph.

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 pressing
End
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

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

. 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.

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!
and
.
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.
