Failure Messages / Failure Memory / Failure Codes
All failures will be stored with date and time of their appearance. To display this messages, 2 pages
exist:
- The "
Actual failures page
" contains all current failures in a short form. To make more than one
current failure visible, use the 'up/down'-keys. If a sensor is short or broken, this message also
appears on the actual value display.
- The "
Historic failures
" page contains the last
15
failures with date and time of their appearance.
Failure Codes
----
............no failure
Init
...........first initialisation of the controller or data lost
Hard
........- hardware failure (from SoftwVers. 6.xx): Internal battery voltage low
MOFF
......mains supply cut off
MON
.........mains supply switched on
SiCh
........security chain open
SBr X
......sensor X broken
SSH X
.....sensor X short
If a sensor is short/broken, a time delay of 5 seconds takes effect before an alarm will be activated.
HT X
........one of the alarm sensors of circuit X high temperature
LT X
.........one of the alarm sensors of circuit X low temperature
MRC X
cooling of circuit X has exceeded maximum runtime. (only active up to '
runtime mess at
').
OPC X
.....alarm on digital (OC) input X, assigned as alarm input
DOR X
.....door contact of circuit X open too long. (only active up to '
runtime mess at
').
DEF X
.....number of defrost cycles without termination by temperature exceeded in circuit X,
maybe too many ice or heater malfunction.
ASSI
........error on assignment page, e.g. function programmed too often
COon
.......controller unit switched ON by interface or by digital input
COof
.......controller unit switched OFF by interface or by digital input
OFF X
.....circuit X switched off by interface or by digital input
Display of actual values and states
All actual values are shown on the '
actual values
'
page.
Display of the temperatures
'
sensor1
' to '
sensor 6
' display their actual value in
the range of -50 ... +100°C. At the same time, the
display shows the functions which are assigned to
the sensor.
Sensor corrections can be made by editing
each individual sensor reading. The resulting
correction factors are listed on the mode page
(
corr sensor 1-6
).
Setpoints:
The active day
or night setpoints
are indicated on
the display by „->“
and „<-“.
Information about delay times
On the actual values page you will find all remaining
delay times, so it is easy to verify the points in
time when specific functions must start.
Status Displays
Temperature Sensors
There are two types of temperature sensors which
can be used:
-
TF 201
, PTC sensor (2000 ohms@25°C),
!! not 3130/1 !!
-
TF 501
, PT1000 sensor (1000 ohms@0°C)
The type must be preset by '
sensor
' (mode
page).

'Standard Display' - Function
After switching on the controller, the display will
indicate the 'Standard Display' after some seconds
(in case of a failure it will display the actual failure).
factory set is the actual value of probe 1.
This will also displayed if you have selected any
parameter and you haven’t touch a button 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
'Standard Display'
- Press "
" and "
" simultaneaously.
The display becomes dark for a moment, after
that the selected parameter will be shown as
the "standard display".
Configuration Concept
The TKx controllers series has a ´
free configu-
rable concept
', that means all in/outputs have no
fixed functions. All inputs and outputs (
6 relays, 6
sensors, 4 digital (OC)-inputs, 1 analog output
) can
be configured to work with any integrated control
functions or all of the 4 control circuits.
Sensors
Each sensor is able to fulfill up to 3 functions at the
same time (function sensor X a, function sensor X
b, function sensor X c, X = sensor no.).
e.g.:
1. control sensor and alarm sensor simultaneous-
ly
2. control sensor and defrost sensor simultaneous-
ly, e.g to control a
chiller
cabinet at the air outlet.
Virtual Sensors
Up to 6 probes can be combined to a "virtual" sen-
sor, which allows an average determination with
adjustable quantifying.
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 allocated
to multiple relays.
Parameters
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 the keys or via interface.
Example of a configuration for a freezer with 3
evaporators:
