Can be selected between 0 and 16. The numbers 1
through 16 indicate the maximum program step to run. If
0 is selected, the thermostat and timer mode are
switched on. In this mode, when the temperature reaches
the set value, the timer is activated and the Alarm1
contact is active at the end of the time.
P.ont. = Behavior Selection on Power-up.
If StoP is selected, program stops when the power is
turned off and on (restart, power loss etc.) and the
program wait for restarting.
If Cont. is selected, program will resume on power-up.
SE.i.p. = Step Increment Parameter.
SE.i.P. Parameter takes values between "0" and C.Hi.L.
parameter. If S.num = 1 to 8 is selected, at the end of
time, Device waits until the difference between the
process value and the target temperature is less than or
equal to SE.i.p. value and then passes to the next step.
If S.num = 0 is selected, timer is stopped and LED
flashes until the difference between the target
temperature and the process value is less than or equal
to SE.i.p.
t.bas. = Time Units.
Can be selected as sEC. or min.
SEC. = Second-time unit selection.
min. = Minute-time unit selection.
C.Con. = Continuous Control Selection.
off = Temperature control is switched off at the end of
the profile.
on = Temperature is kept constant at the last set
value at the end of the profile.

For J - K - T- S and R Thermocouples :
Use the correct compensating cable. Do
not make any supplement to cables.
Connect the thermocouple cables to the
right places at the input terminal.
For resistance (PT100) Sensor :
In order to using 2-wire resistance sensors
(PT100), 8th and 9th terminals must be short
circuited on EUP4420, EUP7420 and
EUP9420 devices. Also on EUP8420
devices, 10th and 11th terminals must be
short circuited. Please check connection
diagrams carefully.
Logic output of the instrument is not electrically
insulated from the internal circuits. Therefore, when
using a grounding thermocouple, do not connect the
logic output terminals to the ground.
1) Mains supply cords shall meet the requirements of
IEC 60227 or IEC 60245.
2) In accordance with the safety regulations, the
power supply switch shall bring the identification of

* Applies to devices with Modbus function.
If A1.P.c parameter is set as on , A1 runs according to profile program value.
If A1.P.c parameter set asindE , A1 output will be activated according to A1.SE. value.
If C.o.SE parameter is set as SSr. , 0-20 or 4-20 and A2.P.c. parameter set as on , A2
runs according to profile program value.
If A2.P.c. parameter set as indE , A2 output will be activated according to A2.SE. value.

ENDA EUPx420 Series PID Temperature
Controllers are intended for installation in
control panels. Make sure that the device is
used only for intended purpose. The shielding
must be grounded on the instrument side.
During an installation, all of the cables that are connected
to the device must be free of energy. The device must be
protected against inadmissible humidity, vibrations,
severe soiling. Make sure that the operation temperature
is not exceeded. All input and output lines that are not
connected to the supply network must be laid out as
shielded and twisted cables. These cables should not be
close to the power cables or components. The installation
and electrical connections must be carried on by a
qualified staff and must be according to the relevant
locally applicable regulations.
PANEL CUT-OUT
1) While panel mounting, additional distance
required for connection cables should be
considered (except EUP9420).
Note :
2) Panel thickness should be maximum 9mm for EUP4420, 10mm for EUP7420,
8mm for EUP8420 and 6mm for EUP9420.
3) If there is no free space at back side of the device, it would be difficult to remove
it from the panel. Required minimum free spaces ;
EUP4420 = 100mm, EUP8420 = 90mm, EUP9420 = 60mm. EUP7420 = 90mm,

Display selection parameter: It can take between 1 and 10 values. When 1 is selected, only the
process value is displayed. When 2 and up values are selected, the step number and the process
value are displayed alternately if 2 or more step profiles are programmed. The entered number
indicates the number of seconds to display the step number. For example, if 4 is entered, the step
number is displayed for 1 second in 4 seconds.
Target temperature difference for increasing the step. (It can be set between 0 and H3 parameter. If
the step time is reached before the target temperature is reached when the profile is checked, then
the difference between the target temperature and the measured temperature is expected to be less
than or equal to this parameter value and then proceed to the next step. If the difference is smaller
than or equal to this parameter, the timer is switched on. See Drawing-4 / page 4 on user manual).

A1 alarm output programming coils in profile steps ;
If PC0=1, A1 output is ON at 1st step.... If PC15=1, A1 output will be ON at 16th step.
If PC33 = 0, in profile mode, the profile is stopped and the first step is returned.
If PC33 = 1, the profile is started in profile mode.
If PD0=1, profile is in constant temperature step.
If PD1=1, profile is in heating step.
If PD2=1, profile is in cooling step.
If PD3=1, profile terminated..
If PD4=1, profile step timer is 0.
PD5=1, profile step timer is running.
If PC34 = 0, the profile continues to run.
If PC34 = 1, the profile operation is put on hold (Hold mode).
If PC35 = 0, the control process is finished when the profile is finished (Control outputs are OFF).
If PC35 = 1, the control is continued according to the last set value when the profile is finished.
If PC37 = 0, output A1 is controlled according to H22 parameter.
If PC37 = 1 and PC32 = 1, output A1 is controlled at each step according to PH35 parameter.
If PC38 = 0, output A2 is controlled according to H27 parameter.
If PC38 = 1 and PC32 = 1, output C / A2 is controlled at each step according to PH36 parameter.
If PC36 = 0, the profile stops and returns to 1st step if power-off.
If PC36 = 1, In case of power-off or restarted and the current step value of the temperature
setpoint(s) are not configured for resuming, returns to the 1st step and the profile stops.

4. MODBUS ERROR MESSAGES
Modbus protocol has two types error, communication error and operating error. Reason of the communication error is
data corruption in transmission. Parity and CRC control should be done to prevent communication error. Receiver side
checks parity and CRC of the data. If they are wrong, the message will be ignored. If format of the data is true but
function doesn’t perform for any reason, operating error occurs. Slave realizes error and sends error message. Most
significant bit of function is changed '1' to indicate error in error message by slave. Error code is sent in data section.
Master realizes error type via this message.

The function code received in the query is not an allowable action for the slave. If a
Poll Program Complete command was issued, this code indicates that no program
function preceded it.
The data address received in the query is not an allowable address for the slave.
A value contained in the query data field is not an allowable value for the slave.

Message sample ;
As you see in command message, coil information of (4A1)h = 1185 is required but there isn’t any coil with 1185 address.
Therefore error code with number (02) (Illegal Data Address) sends.
