2-wire Pt100 / Pt1000 sensor
connected and 3-wire set in the
configuration
Check sensor. Change setting to
2-wire with associated line
resistance.
The display shows
0
Ω
instead of
the measured value
The associated sensor has a
sensor short circuit between 2
wires.
Check sensor wires and replace if
necessary
Display shows nothing
-
Supply voltage not connected
-
Fuse has tripped
-
Devise has an internal defect
-
Connect supply voltage
-
Replace fuse
-
Send in the device for repair
„>>>“ or „<<<“ is displayed
instead of the measured value
Sensor value is greater (800°C) or
less (-200°C) than measuring
range
Check sensor and replace if
necessary
Display is to dark
The display is dimmed after the
set time (
menu -> settings ->
dimming time
), the set brightness
is too low (
menu -> settings ->
brightness
)
Increase the dimming time (
menu
-> settings -> dimming time
),
increase the display brightness
(
menu -> settings -> brightness
)
Device cannot be parameterized
The display shows “code lock” for
each parameter
Code lock active
In case of problems with the code
lock (code forgotten), the
protection can be switched off and
the code can be reset to 504 by
keeping the button pressed up
(approx. 5s) when switching on
the supply voltage. Now the code
lock can be reset.
No access via ethernet
DHCP is on, but no IP address
has been assigned
Check the DHCP server or set a
manual IP address
Invalid network area
Check the address range of the IP
address and the subnet mask
No parameters can be changed
via the browser
User administration active and no
write access for current user
available
Assign write rights to the current
user or disable user
administration. If the admin
password is not known, the user
administration can be deactivated
on the device. Disconnect the
device from the supply voltage,
push the button up, connect the
supply voltage and hold the
button (approx. 5s), reset the user
administration.
