Display Aux/Air
Aux =0
Air = 1
(Setting for the function o09)
Set the temperature value where the output signal must be minimum
(0 or 4 mA)
o27 Temp. at AO min.
(Setting for the function o09)
Set the temperature value where the output signal must be maximum (20 mA). (With a tem-
perature range of 50°C (dierential between the settings in o27 and o28) the dissolution will be
better than 0.1 °C. With 100°C the dissolution wil be better than 0.2°C.)
o28 Temp. at AO max.
Service
A number of controller values can be printed for use in a service situation
Read the temperature at the S
air
sensor (calibrated value) u01 Air temp.
Read the control reference
(Setpoint + any contribution from external signal)
u02 Air reference
Read temperature at the S
aux
sensor (calibrated value)
(This showing can also be uploaded from the normal display, if you push the lowermost button
for almost a second)
u03 Aux. temp.
Read valve’s actuator temperature u04 Actuator temp.
Read reference for valve’s actuator temperature u05 Actuator Ref.
Read value of external current signal u06 AI mA
Read value of transmitted current signal u08 AO mA
Read status of input DI (start/stop input) u10 DI
ICM opening degree.
Only active if (n03)=6
u24 OD%
-- DO1 Alarm
Read status of alarm relay
-- DO2 Cooling
Read status of relay for solenoid valve
-- DO3 Fan
Read status of relay for fan
Operating status
Operating status of the controller can be called forth in the display. Push briey (1s) the upper
button. If there is a status code, it will be shown on the display. (Status codes have lower priority
than alarm codes. In other words, you cannot see a status code, if there is an active alarm).
The individual status codes have the following meanings:
EKC State
(0 = regulation)
S10: Refrigeration stopped by the internal or external start/ stop 10
S12: Refrigeration stopped due to low S
air
12
