CIAT LW 700 Montage-, Betriebs- Und Wartungsanweisung Seite 21

6 Niveau d'huile trop bas
Oil level too low
Ölstand zu niedrig
7 Défaut bobinage moteur
Motor fault
Motorstörung
8- Température de sortie fluide
froid trop élevée
Chilled fluid outlet
temperature too high
Austrittstemperatur der
kalten Flüssigkeit zu hoch
9- Température de refoulement
trop basse se rapprochant de la
température de condensation
Discharge temperature too low,
getting close to the condensing
temperature
Ausblastemperatur zu niedrig, nähert
sich der Verflüssigungstemperatur
Topups not made after interventions
Motor starts too close, anti short cycling out of order
Thermic faulty or out of order
Supply voltage too low
Faulty operation of intensity limiting device
a) Avec pression d'aspiration supérieure à la normale
a) With intake pressure higher than normal
a) Bei erhöhtem Ansaugdruck
Regulating device setting point out of order
Thermal load higher than the one forecasted
Wärmelast über dem vorgesehenen Wert
Water flow too high
Electronic control not working
Chilled fluid inlet or condenser air temperature too high, the intensity limi
ting device prohibits capacity increase
Capacity variation assemblies faulty
b) Avec pression d'aspiration inférieure à la normale
b) With intake pressure lower than normal
b) Bei zu niedrigem Ansaugdruck
Lack of refrigerant fluid
Faulty refrigerant fluid supply to the evaporator
Faulty operation of the compressor liquid injection system
The compressor sucks up too much liquid
Der Verdichter saugt zu viel Flüssigkeit an
Add oil
Set the correct delay between two starts
Set or replace
Check the electrical installation and contact, if required, the power supplying
company
Check the operation of capacity control relay driven by the limiting device.
Check and adjust, if necessary, the setting of the limiting device
Display the correct setting
Check the balances (or put on additional unit on line if available)
Adjust the flow according to forecasted value
Check operation of temperature and capacity controlers
Proceed as under 2 for the condenser
For the evaporator side : wait if the load is normal, the temperature will
decrease progressively
Check the capacity variation coils as well as the absence of leak on the assembly
Locate the leak(s) and top up the load
Check the electrical and expansion valves and possibly the filter dryer fouling
Check the adjustment and operation of the expansion valves on the evaporator
and ECOCIAT. Adjust the settings and/or replace the expansion valve(s) if
required
Check and adjust the refrigerant load
Check the operation of the expansion device supplying the evaporator
