Error Messages / Error Memory / Error Codes
If a failure occurs, the controller will show parameter
L20
with a shortcut (see below) with a flashing
display automatically. If multiple errors are present, they can be called up by the up/down keys. Always
the last
15
error messages keep memorized with date and time of their appearance and can also be
read-out via data interface.

If a sensor is short or broken, a time delay of 5 seconds takes effect before an alarm will be activated.
Display of actual values and states
All actual values are shown on the "
Actual Values
Page
" (
(l)
).
State of the Controller Unit
If the 4 status LEDs
are blinking simul-
taneously and the display shows "oFF", the control
functions are disabled by digital input or data inter-
face.
Humidity Displays
"
L01, L05, L06
" (Actual Values Page) show the
actual values of the humidity sensors 1, 5 and 6 in
the range of 0...+100% r.H.. With "
P31, P35, P36
"
(Mode Page) this displays can be calibrated.
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.
State of inputs/outputs
Digital-(DI)-Inputs State of the relays
Analogue Output: Parameter

Humidity Sensors from ELREHA
These types of Humidity Sensors can be used:
- FF 2520
, output 0...10V or 4...20mA
- FG xxx
, output 0...1000 ohms
The type of sensor can be set by '
h21, h25
and
h26
'
(Assignment Page).
Remote Display
The connection of remote displays of the TAA xx15
series is possible. This displays are able to show
optional the actual values of 'L01', 'L05' and 'L06'.
'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. Factory set is
always the actual value of sensor 1.
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'.
Configuration Concept
The inputs/outputs of the EVP controller have no fixed
tasks. The EVP works with a "
free configurable
"
concept, this means that all available inputs and
outputs (
relays, digital inputs, analogue output
) can
be configured to work with any integrated control
function or control circuit.
Digital Inputs (DI, 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.
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 of the controller
Hereby we use the example from above.
