Operation
Display
The values will be shown with three digits.
Temperature are to be shown in °C and pressure in bar.
Light-emitting diodes (LED) on front panel
The four LED's will flash, if there is an error in the regulation.
In this situation you can upload the error code on the display and
cancel the alarm by giving the uppermost button a brief push.
The controller can give the following messages:
E1
Fault in controller
E15
Cut-out Sgc2 sensor
E16
Error message
Short circuited Sgc2 sensor
E20
Fault on the signal from Pgc
E39
Fault on the signal from Prec
A43
Step motor error. Output or phase
A45
Regulation stopped. Main switch r12 = off
The Pgc gas pressure measured is higher than the
A82
maximum limit for n69
The Pgc gas pressure measured is lower than Pgc
A83
Alarm message
min (A65)
The receiver pressure measured is lower than "n71"
A84
minus "n72"
A94
Pgc alarm limit "A66" is exceeded
A95
Prec alarm limit "A67" is exceeded
The buttons
When you want to change a setting, the two buttons will give you
a higher or lower value depending on the button you are push-
ing. But before you change the value, you must have access to the
menu. You obtain this by pushing the upper button for a couple
of seconds - you will then enter the column with parameter codes.
Find the parameter code you want to change and push the two
buttons simultaneously. When you have changed the value, save
the new value by once more pushing the two buttons simultane-
ously.
Gives access to the menu (or cutout an alarm)
Gives access to changes
Saves a change
Examples of operations
Set a menus
1. Push the upper button until a parameter is shown
2. Push one of the buttons and find the parameter you want to
change
3. Push both buttons simultaneously until the parameter value is
shown
4. Push one of the buttons and select the new value
5. Push both buttons again to conclude the setting
Control starts when the supply is connected
0 V = valve closed
10 V = valve open
Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep both buttons depressed at the same time as you recon n ect the supply voltage

Function
Normal display
Shows the current pressure after the gas cooler
Pushing both buttons briefly will display the
reference
Pushing the bottom button briefly will display
Prec.
Start / stop
Start / stop of regulation
Ramp for reference after heat recovery
Displacement of the Pgc minimum reference
(n89) during heat recovery. (Displacement value
at 10 V)
Alarm Settings
Alarm limit for Pgc Min.
Permitted Pgc reference variation
0 = no alarm function (recommended)
Permitted Prec reference variation
0 = no alarm function (recommended)
Delay time for 'A94' Pgc reference alarm
Delay time for 'A95' Prec reference alarm
Regulating parameters
Actuator type for receiver control
0=ETS12,5/25 / CCM10/20,
1=ETS50 / CCM30, 2=ETS100 / CCM40,
3=ETS250, 4=ETS400,
5=User defined (set: n37 and n38)
6=CCMT2/4/8
P: Amplification factor Kp
I: Integration time Tn
Max. opening degree. of the valve
Number of steps from 0-100% opening degree
(x10) **
Number of steps per second
Max. permitted receiver pressure, Prec
P-belt beyond PrecMax for valve to close
P: Amplification factor Kp for receiver
I: Integration time Tn for receiver
The gas cooler's max. pressure
This is where you set the maximum pressure per-
mitted in the gas cooler. If the pressure reaches
this value, the valve is fully open.
P-band under n69, so the valve is fully open if
the pressure is n69.
Min. pressure in the receiver
This function is only used if the pressure trans-
mitter Prec is mounted.
P-band to force open the valve if the receiver
pressure is too low
Subcooling is required to be regulated accord-
ing to temperature
Set the desired subcooling in K.
The gas cooler's min. pressure
Min. permissible opening degree for ICMTS
Extra capacity when the contact is closed.
(The Pgc reference is increased with this value)
Minimum permitted Pgc reference during heat
recovery (AI > 2 V). The value can be increased
further using the r68 function.
Do you require receiver pressure control: Off=no,
On=yes
Prec. reference for receiver pressure control
Receiver pressure control. Maximum opening
degree for ETS
Receiver pressure control. Smallest opening
degree for ETS
Define the reference curve point at 100 bar.
