While normal operation or if no key is pressed for about 3 minutes, the EVP
displays the following information:
1st priority: current failure (blinking)
2nd priority: operating states (e.g. 'oFF')
3rd priority: selected 'permanent parameter' display

Notice
CONNECTION INFORMATION & SAFETY INSTRUCTIONS
The guarantee will lapse in case of damage caused by failure
to comply with these operating instructions! We shall not be
liable for any consequent loss! We do not accept liability for
personal injury or damage to property caused by inadequate
handling or non-observance of the safety instructions! The
guarantee will lapse in such cases.
This manual contains additional safety instructions in the
functional description. Please note them!
If you notice any damage, the product may not be connected
to mains voltage! Danger of Life!
A riskless operation is impossible if:
• The device has visible damages or doesn't work
• After a long-time storage under unfavourable conditions
• The device is strongly draggled or wet
• After inadequate shipping conditions
• Never use this product in equipment or systems that are
intended to be used under such circumstances that may
affect human life. For applications requiring extremely
high reliability, please contact the manufacturer first.
• The product may only be used for the applications
described on page 1.
• Electrical installation and putting into service must be
done from qualified personnel.
• During installation and wiring never work when the
electricity is not cut-off ! Danger of electric shock!
• To prevent electrical shock, the device may only be
operated in a closed control cabinet or control box.
• Never operate unit without housing.
Danger of electric shock!
• All ‘PE’ terminals must be connected to PE.
Danger of electric shock! Additionally, the internal noise
filter will not work, faulty indicated values may occur.
• Please note the safety instructions and standards of your
place of installation!
• Before installation: Check the limits of the controller and
the application (see tech. data). Check amongst others:
- Make sure that all wiring has been made in accordance
with the wiring diagram in this manual.
- Supply voltage (is printed on the type label).
- Environmental limits for temperature/humidity.
- Maximum admitted current rate for the relays. Compare
it with the peak start-up currents of the controlled loads
(motors, heaters,etc.).
Outside these limits malfunction or damages may occur.
• Sensor/probe cables must be shielded. Don’t install them
in parallel to high-current cables. Shielding must be
connected to PE at the end close to the controller.
If not, inductive interferences may occur.
• Please note for elongation: The wire gauge is not critical,
but should have 0,5mm² as a minimum.
• Mounting the controller close to power relays is
unfavourable. Strong electro-magnetic interference,
malfunction may occur!
• Take care that the wiring of interface lines meets the
necessary requirements.
• All used temperature sensors must be identical. Never
use different types at the same time. This will not work.
• TF-type sensors are not designed for being immersed in
fluids permanently. In such a case, always use dip-fittings.
With extreme temperature variations, the sensor may be
damaged.
Cleaning
The use of a dry, lint-free cloth and household agents is
sufficient to clean the product.
Never use acids or acidic fluids! Risk of damage!

Error Messages / Error Memory / Error Codes
If a failure occurs, the controller will show parameter P43 with an error code with a flashing display automatically. Always the last 15 errot messages keep memorized with date and time of their appearance
and can be read-out via data interface.
---- .............. no error
sel ............ error in assignment page, e.g. function selected too often
Thi ............ alarm sensor, overtemperature
tlo ............ alarm sensor, undertemperature
tXb ............ sensor X broken
tXc ............ sensor X hot-wired
dbt ............ number of defrost cycles without termination by temperature exceeded,
maybe too many ice or heater malfunction.
rrt ............ cooling has achieved maximum runtime. This message is only active at point-in-time
set by
P42 (mode page).
rdo ............ door contact is open too long. This message is only active at point-in-time set
by
P42 (mode page).
dor ............ door X is open
opc ............ alarm at digital input X
cha ............ safety chain open
hrd ............ hardware failure
If a sensor is short or broken, a time delay of 5 seconds takes effect before an alarm will be activated.
Configuration Concept
The inputs/outputs of the EVP-cold storage controller
have no fixed tasks. The EVP works with a "free
configurable" concept, this means that all available
inputs and outputs (relays, sensors, digital inputs,
analogue output) can be configured to work with any
integrated control function or control circuit.
Sensors
Each sensor can fulfill each function, even up to 3
functions at the same time. (Function (a) of sensor
X, Function (b) of sensor X, Function (c) of sensor
X, X = sensor#). e.g.:
1. Control sensor /alarm sensor at the same time
2. Defrost limitation sensor and control sensor at
the same time, e.g. to control a refrigerated
shelf by the temperature of its air outlet.
Virtual Sensors
Up to 4 sensors can be combined to a 'virtual' sensor
to realize averaging with selectable emphasis.
Digital inputs (Optocoupler inputs)
Each digital input can be assigned to one of the
possible functions.
Relay Outputs
Each relay can be used to control one of the possible
functions. The same function can even be assigned
to multiple relays.
Relay output #4 is a Solid State Relay
with a lower contact rating than the
standard relay outputs. Normally, this
output is used for driving Electronic Ex-
pansion Valves, but can be used for any
other task if it works within the specified current
range.
Parameter
Parameters of functions which are not assigned will not
appear in the parameter pages to improve survey.
Assignment
The function of each input and output can be preset
on the 'assignment page'. The assignment can be
done by keys or via interface.
Configuration Example for an EEx-Valve
Configuration of the controller
Hereby we use the example from above: A cold storage with an evaporator with Electronic Expansion
Valve.

Repeat this steps until all inputs and outputs are assigned to the desired functions.
Display of actual values and states
All actual values are shown on the "Actual Values
Page" ((l)).
Status of the controller unit
If the 4 status LED's on the front are blinking
simultaneously and the display shows "oFF", the
control functions are disabled by digital input or
data interface.
Display of temperatures
"L01" -" L04" (Actual Values Page) show the actual
temperature value of the sensors 1-4 in a range
within -100... +100°C. "L05" shows a temperature
value which is calculated from the pressure value
of the transducer and the selected refrigerant table,
"L07" shows the 'virtual' temperature value.
With "P31"-"P34" and "P36" (Mode Page) this
displays can be calibrated.
Expansion Valve Status Display
This shows the current, average aperture size
from 0...100 % and additionally the actual state
of the valve.
cut = Restart of the evaporator after abnormal
operating conditions (cutoff)
pdo = Pumpdown of the refrigerant
(cooling relay ON for 30 sec.)
Setpoints
The active day or night setpoints are indicated by
the left decimal point switched on.
Time information
The Actual Values Page contains all runtime- /
remaining time information, so the times up to the
start of a function can be read.
Status of inputs/outputs
Digital-(OK)-Inputs State of the relays
Analogue Output: Parameter L50, value in %
Temperature Sensors
These types of temperature sensors can be used:
- TF 201, PTC sensor (2000 ohms@25°C)
- TF 501, PT1000 sensor (1000 ohms@0°C)
- customer specific sensor So1 (-40...+25°C)
- customer specific sensor So2 (-50...+50°C)
The type of sensor can be set by 'P35' (Mode
Page).
Please don't use the TF 201 sensor
if you work with Electronic
Expansion Valves.
'Permanent Parameter' - Function
After power-up of the controller, the display will
indicate the 'permanent parameter' after some
seconds (or in case of a failure it will display the
current failure). This can also be read if you don’t
touch a key for more than 3 minutes.
If you think that it is suggestive to show any sensor
value as permanent parameter, do the following:
Change permanent parameter
- Select the parameter you want to have as
'permanent parameter'
- Press "
" and " " simultaneously.
The display shows "
888" for a moment, after
that the selected parameter will be shown as
the 'permanent parameter'.
